has at least 128 MB of RAM, support for Microsoft DirectX 9, and Microsoft Pixel Shader 2.0.

QUESTION 2
You are employed as a network administrator at Certkingdom.com. The Certkingdom.com network consists of a
single Active Directory domain named Certkingdom.com.
A client computer named Certkingdom-WS620 is running Microsoft Windows 2000 with Service Pack 3.
Certkingdom-WS620 also runs some legacy applications. The Certkingdom.com management wants all computers
to be running Microsoft Windows Vista. To this end you have received instructions from the CIO to
uCertkingdomrade Certkingdom-WS620 to Microsoft Windows Vista.
Which two steps should you take to uCertkingdomrade Certkingdom-WS620 and keeping the current applications
intact and not requiring reinstallation?

A. By Installing Windows Vista into a separate partition.
B. By using the Windows Easy Transfer wizard.
C. By uCertkingdomrading to Microsoft Windows XP Professional.
D. By uCertkingdomrading to Windows Vista.
E. By installing the latest version of the Service Pack.
F. By copying your user profile to a removable media.
G. By Performing a clean installation of Windows Vista.
H. By Copying the user profile to the C:\Windows\Users directory.

Answer: C,D

Explanation: To move to Windows Vista without having to reinstall your applications, you need to
do an ‘in-place’ uCertkingdomrade. However, you cannot uCertkingdomrade directly to Windows Vista from
Windows 2000 Professional (you would need a clean install which would delete your applications).
Therefore, you need to uCertkingdomrade to Windows XP Professional first. Then you can uCertkingdomrade to
Windows Vista and keep the applications.

QUESTION 3
You are employed as a network administrator at Certkingdom.com. The Certkingdom.com network consists of a
single Active Directory domain named Certkingdom.com. All client computers on the Certkingdom.com network run
Microsoft Windows Vista.
Certkingdom.com contains a client computer named Certkingdom-WS621. Certkingdom-WS621 has been assigned to a
Certkingdom.com user named Andy Booth. You received a report from Andy Booth complaining that CertkingdomWS621
is performing slower than it should. You have a suspicion that it could be malware that is
causing the problem.
How can you find out what is causing the problems?

A. You need to run a Windows Defender scan.
B. You need to view the processes list in Task manager.
C. You need to view the startup items in the System Configuration utility.
D. You need to run Disk Defragmenter.

Answer: A

Explanation: Windows Defender is an application that can scan for malware or other potentially
harmful files. You can initiate a Windows Defender scan to scan all the files on your system for
malware or other potentially harmful files.

QUESTION 4
You are employed as a network technician at Certkingdom.com. The Certkingdom.com network consists of a
single Active Directory domain named Certkingdom.com. All client computers on the Certkingdom.com network run
Microsoft Windows Vista.
A Certkingdom.com user named Andy Booth has been assigned a client computer named Certkingdom-WS629.
One morning Andy Booth complains that Certkingdom-WS629 does not produce any sound when he
views a video file clip. You open the Device Manager as shown below.

What configuration change should you make to Certkingdom-WS629?

A. You need to update the driver for the audio device.
B. You need to uninstall the device then run a hardware scan.
C. You need to enable the audio device in Device Manager.
D. You need to change the IRQ for the device.
E. You need to run Microsoft Windows Update and install the latest updates for Certkingdom-WS629.
F. You need to replace the audio device with one that is compatible with Windows Vista.

Answer: C

Explanation: The icon by the sound device (the Creative SB Live! Series device) shows that the
device is disabled. Therefore, to receive audio output from Certkingdom-WS629, you simply need to
enable the device. You can do this by right-clicking on the device and selecting Enable.

QUESTION 5
You are employed as a help desk technician at Certkingdom.com. The Certkingdom.com network consists of a
Workgroup named Certkingdom. The client computers on the Certkingdom.com network run a mix of Windows XP
Professional and Windows Vista. You
The Certkingdom.com management wants to conduct a meeting with all their users. You need to facilitate
this meeting. However, invitation to the Certkingdom.com users are not getting sent as they do not appear
in the Invite people list of the Microsoft Windows Meeting Space meeting.
What should you do to be able to invite all Certkingdom.com users to the Windows Meeting Space
meetings? (Each correct answer presents part of the solution. Choose TWO.)

A. You need to instruct the Certkingdom.com users with Windows XP Professional computers to create an
exception for invitations from Windows Meeting Space in the Microsoft Windows Firewall.
B. You need to uCertkingdomrade the Windows XP Professional computers to Windows Vista.
C. You need to configure the Windows XP Professional computers to use Microsoft NetMeeting to
connect to the meeting.

Microsoft 70-442 Q & A / Study Guide

Best Microsoft MCTS Certification, Microsoft MCITP Training at certkingdom.com

QUESTION 1
You work as a contract developer for National Retailers. You are currently working
on the online order application the National Retailers database developer has
informed you that the product parts and components will be stored in a xml data
type column. National Retailers employees are allowed to request product
information regarding a doll or action figure line by clicking a button on the Web
form. The data will only be retrieved if the employee requests details.
You need to design the appropriate data access technologies and must thus choose
the object that you need to use to store the query results for product parts and
component information.
What should you do?

A. Make use of a DataSet object.

B. Make use of an XmlElement object.

C. Make use of an XmlDocument object.

D. Make use of an XmlDocumentFragment object.

Answer: D

Explanation: An XmlDocumentFragment object can store either a well-formed
XML document or a fragment of a document. This would be consistent with the xml
data type which has the ability to store well-formed documents as well as fragments.
1. The National Retailers management wants to expand business by selling their
exclusive doll line on the company Web site
Incorrect Answers:
A: A DataSet object is used when the method returned a relational data set, akin to the
method that is generated from a SELECT statement.
B: An XmlElement object is used to store the results of a SELECT ... FOR XML query,
not the contents of a single value.
C: An XmlDocument object must store well-formed XML Documents. It is thus not
compatible with the xml data type.

QUESTION 2
You work as the database developer for National Retailers. You need to optimize
the indexing strategies and are thus designing the indexes for the Sales.Orders table.
The query in the following exhibit is frequently executed, though it is not the most
commonly executed query.
SELECT Salesrepresentative, SUM(Commission)
FROM Sales.Orders
WHERE Date BETWEEN @ startDate AND @ endDate
GROUP BY Salesrepresentative
ORDER BY Salesrepresentative
You need to use the appropriate statement to create the best index to accommodate
this query.
What should you do?

A. Use the following statement:
CREATE INDEX ix_Commission
ON Sales.Orders(Salesrepresentative, Date, Commission)

B. Use the following statement:
CREATE CLUSTERED INDEX ix_Commission
ON Sales.Orders(Salesrepresentative, Date)

C. Use the following statement:
CREATE INDEX ix_Commission
ON Sales.Orders(Date)
INCLUDE (Salesrepresentative);

D. Use the following statement:
CREATE INDEX ix_Commission
ON Sales.Orders(Date, Salesrepresentative)
INCLUDE (Commission);

Answer: D

Explanation: The Date column is used to select the records and the
Salesrepresentative column is used to group and order the records. This means that
both these columns have to be key columns. The Date column is used in a
BETWEEN comparison, thus it should also be the first in the query. Furthermore,
it has higher selectivity than the Salesrepresentative column.
1. Sales Representatives should also be allowed to check the current commissions due to them.
Incorrect Answers:
A: The column used for equality or BETWEEN comparisons should be listed first. This
must then be followed by the most selective column, then the rest of the predicate
columns in order of decreasing selectivity. And, although it is possible that you can
create an index by using a computed column as the key column, it is recommended that
key columns be kept as narrow as possible. This means that making use of an included
column for Commission is a better option.
B: A Clustered index should have high selectivity. The Salesrepresentative column does
not have high selectivity. This means that this clustered index will not be appropriate for
any other queries done against the table like retrieving order information for instance. A
table can only have one unique index.
C: The Salesrepresentative column is used in the GROUP BY clause. Thus it would be
better suited as the key column rather than an included column. Furthermore, this is not a
covering index as it does not include Commission as an included column.

QUESTION 3
You work as the database developer for National Retailers. While busy designing
queries for the retrieval of data from XML sources, you are writing a script that
will generate an XML file to be imported into the collections application. This
application assumed XML data includes both elements and attributes.
You need to make a choice of the most appropriate type of Transact-SQL statement
to use to retrieve the data from the database.
What should you do?

A. Make use of the OPENXML Transact-SQL statement.

B. Make use of the sp_xml_preparedocument stored procedure.

C. Make use of the SELECT ... FOR XML AUTO Transact-SQL statement.

D. Make use of the SELECT ... FOR XML PATH Transact-SQL statement.

Answer: D

Explanation: The FOR XML PATH clause of the SELECT
statement will allow you to use XPath to define the structure for the XML data that
is returned. This structure can include both elements and attributes.
1. The Chicago office handles debt collection. All customers with an outstanding balance
over 60 days are also sent to the Chicago office. The accounting department makes use of
a collections application that imports XML data.
Incorrect Answers:
A: The OPENXML statement is used to insert XML data into relational tables. Not to
retrieve a resultant set formatted as XML from relational tables.
B: The sp_xml_preparedocument system stored procedure is used prior to calling OPENXML.
C: The FOR XML AUTO clause of the SELECT statement will generate a result set of
nested elements and as such do not make allowance for a mix of elements and attributes.

QUESTION 4
You are busy designing the database query strategy for National Retailers that will
retrieve the result set used to report on monthly sales trends. To this end you are
designing the stored procedure. This stored procedure will be used by an
application that makes use of Microsoft Visual C# .NET.
Of the requirements that you need to keep in mind is that the analysts need the
ability to retrieve a result set with approximately 100 records and scroll through
them to gather information. These analysts will need the ability to locate records
based on either factory or product I
D. They do NOT update any data. You thus
need to design the most appropriate cursor strategy for National Retailers.
What should you do?

A. Create a server-side static cursor.

B. Create a server-side dynamic cursor.

C. Create a client-side forward-only cursor.

D. Use a default result set and do not create a cursor.

Answer: D

Explanation: The Default Result Set caches all records in the result set to the client.
This will thus reduce round trips across the network to one and prevent data from
being stored in the tempdb.
1. Regularly at the end of each month, reports are generated manually and e-mailed to the
Chicago office. Monthly sales and invoice aging information is included in these reports.
Incorrect Answers:
A: If you create a Server-side static cursor it will consume server resources and require a
round-trip across the network each time the client fetches data. Furthermore the cursor
will then be stored in tempdb.
B: A Server-side dynamic cursor does require a round-trip across the network every time
a client fetches data.
C: Creating a Client-side forward-only cursor will not allow analysts to scroll through
the data the way that they require to. These cursors only support the ability to fetch the
next record and not to move to a specific record.

QUESTION 5
You work as the database developer for National Retailers. You are currently
designing the code that will retrieve the product information for the online order
application. To this end you need to determine the appropriate type of object that
you should create to return to the Web application. The Web application will
require that information such as product name, product description, and product
price information be returned in response to a search request.
What should you do?

A. Use a Transact-SQL stored procedure.

B. Use an extended stored procedure.

C. Use a table-valued user-defined function.

D. Use a Common Language Runtime (CLR) user-defined function.

Answer: A

Explanation: The online application accesses data via a Native XML Web service.
This means that you are limited to using an object that can be exposed as a Web
method. A Transact-SQL stored procedure can return the required information and
can be exposed as a Web method.
1. The National Retailers management wants to expand business by selling their
exclusive doll line on the company Web site.
2. The future online Sales application will be outsourced. NRCH-DB02 will host a
database to support the e-commerce application. The e-commerce application will make
use of Simple Object Access Protocol (SOAP) to retrieve product information and submit
orders.
Incorrect Answers:
B: An Extended stored procedure cannot be exposed as a Web method.
C: A Table-valued user-defined function cannot be exposed as a Web method.
D: A CLR user-defined function is not required because the data can be retrieved using
Transact-SQL.

QUESTION 6
You are designing the error-handling routines for National Retailers. You are
creating a function that will be used to check the audit trail for the products. This
function must raise a custom error in the event of the audit trail not being
verifiable. Do bear in mind that the code to check the audit trail requires a query
and a cursor.
What should you do?

A. Use the following error-handing method:
-- Perform query and open the cursor
-- Run code that iterates through the cursor and checks the audit trail
IF @@ERROR
RAISERROR @@ERROR

B. Use the following error-handing method:
BEGIN TRY
-- Perform query and open the cursor
-- Run code that iterates through the cursor and checks the audit trail
END TRY
BEGIN CATCH
RAISERROR (@myCustomError, 15)
END CATCH

C. Use the following error-handing method:
--Perform query and open the cursor
--Fetch the first row
WHILE /*not the last row*/
IF /*Code that checks the audit trail*/
--Fetch the next row
ELSE
SET @@ERROR = @myCustomError
END WHILE

D. Use the following error-handing method:
--Perform query and open the cursor
--Fetch the first row
WHILE /*not the last row*/
IF /*Code that checks the audit trail*/
-- Fetch the next row
ELSE
RAISERROR (@myCustomError, 15)
END WHILE

Answer: D

Explanation: You need to pass the error message back to the application via an IF
ELSE statement to check the values in a row, then calling RAISERROR in the event
of the values being invalid. The RAISERROR function will allow you to send an
error message up the calling chain.
1. Industry regulations require an audit trail for all components and parts that go into a
doll or action figure. The audit trail must be able to use the UPC number on the package
to trace all the components and parts, who supplied the components and parts, and what
date the components and parts were shipped. Components and parts information must be
entered at the time the product line is created and cannot be altered after the quality
inspection. Attempts to modify components and parts information after the inspection
time must be logged.
2. Only product lines with an intact audit trail can be shipped. If an audit trail is not
available, the product line must be destroyed. The product line application includes a
verification routine that checks a specific product line's audit trail. The application makes
use of structured error handling to react to a product line that must be destroyed.
Incorrect Answers:
A: The requirements will not be met if you use @@ERROR after iterating through the
cursor. The @@ERROR global variable contains the error number generated by the last
statement. Thus if will only include an error number if the last statement to process the
cursor is responsible for the error.
B: Using a TRY ... CATCH block within a function is not possible.
C: @@ERROR is a global variable that is automatically set by SQL Server every time a
statement executes. Thus you cannot set @@ERROR.

QUESTION 7
You are designing the error-handling routines for the National Retailers Web
application. In the event of a customer failing to enter valid payment information,
you need to send a custom error to the calling application. Furthermore, this error
message has to be localized to the user's language. The Web application will pass the
language when it opens a connection to the database server. You thus need to decide
which would be the most appropriate way to support error messages in multiple
languages.
What should you do?

A. A CASE statement should be added to the CATCH block.
Then call RAISERROR with a different error message for each language.

B. A different error number should be used for each language version.
Then a CASE statement should be added to the trigger and call RAISERROR with
the language-specific error.

C. Add a message for each language using sp_addmessage.
A different error number should be used for each language version.
Raise the error in the @@ERROR global variable.

D. Add a message for each language using sp_addmessage.
The same error number should be used for each language version.
Call RAISERROR from the trigger.

Answer: D

Explanation: The same error numbers should be used when adding an error
message for each language. This will allow SQL Server to match the session
language to the error message language when you call RAISERROR. The
sp_addmessage stored procedure is used to add an error message.
1. The National Retailers management wants to expand business by selling their
exclusive doll line on the company Web site.
2. The future online Sales application will be outsourced. NRCH-DB02 will host a
database to support the e-commerce application. The e-commerce application will make
use of Simple Object Access Protocol (SOAP) to retrieve product information and submit
orders.
Incorrect Answers:
A: A CASE statement should not be added to the CATCH block and then call
RAISERROR with a different error message for each language. This will make
maintenance quite difficult since you will then be required to modify the code that calls
RAISERROR if a message changes or you need to add a language.
B: There is no need to use a different error number for each different language version
and then add a CASE statement to the trigger. This option will work, though it will be
difficult to maintain since the trigger will then have to be modified each time a language
is added. It will also require more programming effort instead of allowing SQL Server to
choose the right language for the error message.
C: If you raise the error in @@ERROR, then the error associated with the last statement
will be raised and not the custom error message. Also, there is no need to define a
different error number for each language version.

QUESTION 8
You are designing the error-handling routines for National Retailers. You thus need
to design the code that will validate the audit trail for a product batch.
Users that do not enjoy membership of the sysadmin role will run the
fn_ValidateBatch function. You need to use the appropriate statements to ensure
that in the event of an invalid audit trail, an error is raised to the calling application
and an event is written to the application log.
What should you do?

A. Use the following statements:
sp_addmessage (@msgnum=50888, @severity=15, @msgtext="Batch" + @b "cannot be
validated.")
and
RAISERROR(50888, @batchnum, WITH LOG)

B. Use the following statements:
sp_addmessage (@msgnum=50888, @severity=16, @msgtext="Batch %b cannot be
validated.")
and
RAISERROR (50888, WITH SETERR, @batchnum)

C. Use the following statements:
sp_addmessage (@msgnum=50888, @severity=16, @msgtext="Batch %b cannot be
validated.")
and
RAISERROR (50888, %batchnum)

D. Use the following statements:
sp_addmessage (@msgnum=50888, @severity=16, @msgtext="Batch %b cannot be
validated.")
and
RAISERROR(50888, @batchnum, WITH LOG)

E. Use the following statements:
sp_addmessage (@msgnum=50888, @severity=21, @msgtext="Batch %b cannot be
validated.")
and
RAISERROR(50888, @batchnum, WITH LOG)

Answer: D

Explanation: By specifying the 16 severity level, you ensure that the users who do
not belong to the sysadmin role have the ability to raise the error. Also this option
displays the correct syntax for using arguments in a message text string. By default,
only messages with a severity level of over 19 are logged to the application log. This
can be overridden by specifying WITH LOG when calling RAISERROR.
1. Industry regulations require an audit trail for all components and parts that go into a
doll or action figure. The audit trail must be able to use the UPC number on the package
to trace all the components and parts, who supplied the components and parts, and what
date the components and parts were shipped. Components and parts information must be
entered at the time the product line is created and cannot be altered after the quality
inspection. Attempts to modify components and parts information after the inspection
time must be logged.
Incorrect Answers:
A: This option would be correct except for the severity level of 15. By default, only
messages with a severity level of over 19 are logged to the application log. This option
does not offer any overriding probabilities to have the error logged to the application log.
B: This option is only partly correct. But you should not raise the error by specifying
SETERR. This will result in @ERROR and ERROR_NUMBER to be set to 50000. You
do not make use of a concatenated string to use an argument in the message text.
C: The RAISERROR (50888, $batchnum) is the incorrect syntax. A local variable starts
with an @ and not a %. Also this option will not cause the application to be logged to the
application log.
E: You should not specify a severity of 21. Messages with this severity level can only be
raised by members of the sysadminrole.

QUESTION 9
You work as the database developer for National Retailers. You are currently
designing the indexes that will be used for the OnlineSales.Customers table. The
following exhibit illustrates the most common query that will be used.
SELECT FirstName, LastName, Address, City, State, Zip
FROM OnlineSales.Customers
WHERE CustomerID = @emailAddress
You thus need to select the best statement that should be used to create this index
that will accommodate this query.
What should you do?

A. Use the following statement:
CREATE INDEX ix_custInfo
ON OnlineSales.Customer(CustomerID)
INCLUDE (FirstName, LastName, Address, City, State, Zip);

B. Use the following statement:
CREATE INDEX ix_custInfo
ON OnlineSales.Customer(LastName, FirstName)
INCLUDE Address, City, State, Zip;

C. Use the following statement:
CREATE CLUSTERED INDEX ix_custInfo
ON OnlineSales.Customer(CustomerID, FirstName, LastName, Address, City, State,
Zip);

D. Use the following statement:
CREATE CLUSTERED INDEX ix_custInfo
ON OnlineSales.Customer(CustomerID)
INCLUDE (LastName, Address, FirstName, City, Zip, State);

Answer: A

Explanation: Making use of this statement will create an index with a small unique
key that covers the entire query. For optimal performance a small key size that
includes the columns used in the
WHERE clause and other predicates or in joins are recommended. In this scenario
the only required key column would be the CustomerID column. Then you can
include the rest of the columns as non-key columns. This means that you need to
create the index as a non-clustered index because non-key included columns are not
supported for clustered indexes.
1. The National Retailers management wants to expand business by selling their
exclusive doll line on the company Web site.
Incorrect Answers:
B: This index would not be used for the query because the CustomerID column is not
listed as a key column.
C: This statement, if created will result in an index with 344 bytes in the key column.
Though it is possible, it is not optimal since it is better to create an index with a smaller
key column and included columns.
D: This is incorrect because you cannot make use of included columns in a clustered
index.

QUESTION 10
National Retailers require a database that will support the e-commerce application.
You need to find a way to provide the e-commerce application with information
about the existing inventory. The database must determine the nearest factory that
has the product ordered in stock and send the order to that specific factory to have
it fulfilled.
You thus need to determine how the inventory information should be made
available to the e-commerce application while providing the best possible
performance when placing the order.
What should you do?

A. Query the database server at each factory using OPENROWSET from a stored
procedure run on NRCH-DB02.

B. At each factory implement an HTTP endpoint on the database server and expose a
Web method that checks inventory.

C. Replicate the data from the database servers at the different factories to the
NRCH-DB02 server using merge replication.

D. Use a linked server for the database server at each factory at NRCH-DB02.

Answer: C

Explanation: Using merge replication to replicate all data from the factories to
NRCH-DB02 will make the data available locally and improve query performance when
an order is placed. This is the best type of replication to use in this case because there
could be conflicts by orders placed over the Web and order places by the Sales
representatives at each factory. Also in a case where the different sites/factories are not
well-connected making use of merge replication makes sense. And in this case the
factories are connected to the Chicago office by demand-dial links.
1. The National Retailers management wants to expand business by selling their
exclusive doll line on the company Web site.
2. The future online Sales application will be outsourced. NRCH-DB02 will host a
database to support the e-commerce application. The e-commerce application will make
use of Simple Object Access Protocol (SOAP) to retrieve product information and submit
orders.
Incorrect Answers:
A: Making use of OPENROWSET to query each database server at each factory from a
stored procedure on NRCH-DB02 will result in one or more remote queries to be sent
across the network for each product ordered.
B: Making use of an HTTP endpoint will result in more overhead than is required. There
is already a demand-dial connection between the Chicago office and the different
factories. Thus there is no firewall that restricts incoming protocol to only HTTP. Making
use of a SOAP request will result in even more overhead than a remote query.
D: Making use of a linked server for the database server at each factory and performing a
remote query is not the best solution because each product that is ordered will cause at
least one, and possible more, remote queries to be sent across the network.

Free Microsoft 70-291 Q & A / Study Guide Part II

Best Microsoft MCTS Certification, Microsoft MCITP Training at certkingdom.com

QUESTION 1:

A. On Certkingdom -PR01, run the net session command.
B. On Certkingdom -PR01, run the netstat command.
C. On Certkingdom -PR01, run the netsh command.
D. On Certkingdom -PR01, run the netcap command.

Answer: D

Explaination: Netstcap.exe is a command line tool that could be used to capture the
network traffic. A filter can be created to be used during the capture to determine the
MAC address the print jobs are being sent to. The Network Monitor Capture Utility (
Netcap.exe) can be used to capture network traffic in Network Monitor. Netcap provides
capture abilities only from a command prompt; to open the resulting capture (.cap) files,
you must use the full Network Monitor interface. Netcap is installed when you install the
Support tools that are on the Windows XP CD-ROM. Netcap provides capture abilities
that are similar to the version of Network Monitor that is included with the Windows
Server products; however, you must use Netcap at a command prompt. Netcap installs
the Network Monitor driver and binds it to all adapters when you first run the Netcap command.
Incorrect Options:
A: The net session command can be used to view the computer names and user names of
users on a server, to see if users have files open, and to see how long each user’s session
has been idle. Net session manages server computer connections – used without
parameters, net session displays information about all sessions with the local computer.
B: The netstat command is not a utility to use when troubleshooting NetBIOS names, but
is used to display TCP/IP and port information.
C: The Network Shell utility (Netsh.exe) can perform a wide range of system
configuration tasks. You can use commands in the Netsh Interface IP context to
configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and
WINS servers) and to display configuration and statistical information.

QUESTION 2:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of two subnets. All servers on the Certkingdom.com network run
Windows Server 2003 and all client computers run Windows XP Professional. All
servers are located in a central data center that uses a single IP subnet and all client
computers are located in one subnet.
The data center contains two routers named Certkingdom -SR01 and
Certkingdom -SR02, two domain controllers named Certkingdom -DC01 and
Certkingdom -DC02, and two file servers named Certkingdom -SR03 and
Certkingdom -SR04. The IP addresses of these servers are indicated in the table
below.

Host name	IP address
Certkingdom-DC01	10.10.10.1
Certkingdom -DC02	10.10.10.2
Certkingdom -SR01	10.10.1.1
Certkingdom -SR02	10.10.1.2
Certkingdom -SR03	10.10.11.1
Certkingdom -SR04	10.10.11.2

You have received instruction from the CIO to install a new database server in the
data center. You install Windows Server 2003 on a new server computer named
Certkingdom -DB01 and hand it over to a database administrator named Dean
Austin. Dean Austin installs Microsoft SQL Server 2005 and makes some changes to
the TCP/IP settings on Certkingdom -DB01 as shown in the following table.

Parameter	Value
IP address	10.10.1.3
Subnet mask	255.255.255.0
Default gateway	10.10.1.2

Later, Dean Austin complains that Certkingdom -DB01 cannot communicate with the
other servers in the data center. All other servers in the data center can
communicate with the other servers as well as the client computers. You log on to
Certkingdom -DB01 and attempt to ping Certkingdom -DC01 but you receive the
following error message: “Destination host unreachable”.
What should you do to ensure that Certkingdom -DB01 can communicate with the
other computers in the Certkingdom.com network?

A. Configure Certkingdom -DB01 with a default gateway of 10.10.1.1.
B. Configure Certkingdom -DB01 with a subnet mask of 255.255.0.0.
C. Configure Certkingdom -DB01 with an IP address of 10.10.10.3.
D. Configure Certkingdom -DB01 with an IP address of 10.10.11.3.

Answer: B

Explaination: Large networks are subdivided to create smaller subnetworks to reduce
overall network traffic by keeping local traffic on the local subnet and sending all
nonlocal traffic to the router. In order to create a subnetwork, we need to have a system
for addressing that allows us to use the network ID and host ID within the class-based
system. This is accomplished through the use of a subnet mask. To determine the
appropriate custom subnet mask (typically referred to simply as subnet mask) for a
network, you must first:
1. Determine the number of host bits to be used for subnetting.
2. Determine the new subnetted network IDs.
3. Determine the IP addresses for each new subnet.
4. Determine the appropriate subnet mask.
Incorrect Answers:
A: You need to assign the correct subnet mask to ensure connectivity.
C, D: The problem in this scenario is not a faulty IP address. It is the appropriate subnet
mask that has to be determined to enable connectivity.

QUESTION 3:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of two subnets named Subnet A and Subnet B. Subnet A and
Subnet B are connected by a router. All computers on the Certkingdom.com network
are configured with static IP addresses. All network servers run Windows Server
2003 and all client computers run Windows XP Professional.
Certkingdom.com hires a new Sales manager named Amy Wilson. You install a new
client computer named Certkingdom -WS291 for Amy Wilson. You then add
Certkingdom -WS291 to Subnet A. The relevant portion of the network is configured
as shown in the exhibit.

However, Amy Wilson complains that Certkingdom -WS291 cannot communicate
with other hosts on the network.
What should you do to ensure that Certkingdom -WS291 can communicate with all
local and remote computers on the Certkingdom.com network?

A. Configure Certkingdom -WS291 with a default gateway of 192.168.28.84.
B. Configure Certkingdom -WS291 with a default gateway of 192.168.2.1.
C. Configure Certkingdom -WS291 with a subnet mask of 255.255.255.128.
D. Configure Certkingdom -WS291 with a subnet mask of 255.255.255.192.

Answer: C

Explaination: It is evident from the exhibit that the file server and
Certkingdom -WS291 have a different subnet mask. This is the reason why they
cannot communicate with each other. You must therefore change the subnet mask
of Certkingdom -WS291 to 255.255.255.128.
Incorrect Answers:
A, B: The problem is not the gateway IP address that is faulty, but rather the subnet
mask.
D: This option suggests the correct object that has to be changed, but it gives the wrong
subnet mask.

QUESTION 4:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com
Certkingdom.com has its headquarters in Chicago and branch offices in Dallas and
Miami. All servers on the Certkingdom.com network run Windows Server 2003 and all
client computers run Windows XP Professional. You work in the Miami branch
office.
The network at the Miami branch office consists of 25 different subnets, each with a
maximum of six computers. The network administrator at headquarters has
allocated the 192.168.3.0/24 network address to the Miami branch office.
You install a new server named Certkingdom -SR21 in the Miami branch office. You
need to configure the Internet Protocol (TCP/IP) properties for Certkingdom -SR21.
You configure Certkingdom -SR21 with an IP address of 192.168.3.44. What subnet
mask should you use?

A. A subnet mask of 255.255.255.0.
B. A subnet mask of 255.255.255.128.
C. A subnet mask of 255.255.255.192.
D. A subnet mask of 255.255.255.240.
E. A subnet mask of 255.255.255.248.

Answer: E

Explaination: The network address is: 192.168.2.0/24, which means
11111111.11111111.11111111.0 in binary.
Therefore, you can use the last octet to configure the 30 subnets and 6 hosts in each
subnet
You need only six host PCs. When you convert to binary, it is: 00000111. As a result,
you use 3 bits.
This leaves 5 bits for the subnets 11111000 converted to decimal:
128+64+32+16+8=248, therefore the subnet mask will be: 255.255.255.248.

QUESTION 5:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com
Certkingdom.com has its headquarters in Chicago and a branch office in Dallas. All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. You work in the Dallas branch office.
The network at the Dallas branch office consists of a single subnet that contains 150
client computers and 12 servers. The network administrator at headquarters has
allocated the 10.10.0.0/16 network address to the Dallas branch office.
You have received instruction from your manager to place all servers at the Dallas
branch office into a separate subnet that uses the 192.168.10 public addressing
scheme. Your manager asks you to make allowance for a maximum of 30 servers in
the new subnet.
Which subnet mask should you use for the new subnet?

A. 255.255.255.224
B. 255.255.255.240
C. 255.255.255.248
D. 255.255.255.252
E. 255.255.255.254

Answer: A

Explaination: A 255.255.255.224 subnet mask gives five host address bits, so the
maximum number of host addresses is 2 ^ 5 – 2 = 30 host addresses. Thus
255.255.255.224 is the only subnet mask that will allow for sufficient IP addresses in
case of further growth, whilst still conserving as many current addresses as possible.

QUESTION 6:

DRAG DROP
You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional.
You have installed a new server named Certkingdom -SR06 on the network. The
relevant portion of the network is shown on the exhibit.

You want to configure Certkingdom -SR06 with a valid static IP configuration.
Certkingdom -SR06 must be able to communicate with all hosts on the network and
on the internet. You also need to configure Certkingdom -SR06 to use the DNS server
on the local subnet for name resolution. In addition, you must configure redundancy
for name resolution.
How should you configure Certkingdom -SR06?
To answer drag the appropriate IP addresses and Subnet masks to the appropriate
places.

Answer:

Explaination:
The Class C address 192.168.0.100 has to be the IP address to enable
Certkingdom -SR06 to communicate with all hosts on the network and on the internet
as 192.168.0.1, 192.168.0.2 and 192.168.0.110 are already in use. 192.168.5.2 and
192.168.5.100 are on the wrong subnet, and besides, 192.168.5.12 is already in use.
The subnet mask for this Class C address is 255.255.255.0. The default gateway
should be 192.168.0.1. To configure redundancy for name resolution, configure the
preferred DNS server/primary address as 192.168.0.2, and the alternate DNS
server/secondary address as 192.168.5.2.

QUESTION 7:

A. On the DHCP server, increase the DHCP lease period.
B. Configure alternate IP settings for Certkingdom -SR25 on the Alternate Configuration
tab of the Internet Protocol (TCP/IP) properties.
C. Configure the DHCP scope in the 169.254.0.1. – 169.254.255.254 range.
D. On the DHCP server, configure the DHCP 001 Resource Location Servers reservation
option for Certkingdom -SR25.

Answer: B

Explaination: Windows Server 2003 includes the Alternate Configuration feature.
The Windows Server 2003 servers can be configured to use an alternate static IP
configuration if a DHCP server is unavailable. When a DHCP client determines that
the DHCP server is unavailable, it will automatically change over and also configure
the TCP/IP stack with the static address information specified on the Alternate
Configuration tab of the Internet Protocol (TCP/IP) properties.
Incorrect Answers:
A: Increasing the lease period would result in DHCP clients requesting leases less
frequently, but won’t guarantee that Certkingdom -SR25 will be available when the DHCP
server is down.
C: Modifying the DHCP scope to the 169.254.0.1. – 169.254.255.254 range will still be
reliant on the DHCP server.
D: Configuring the DHCP 001 Resource Location Servers reservation option for
Certkingdom -SR25 on the DHCP server will not ensure that Certkingdom -SR25 will
receive an IP address or have the IP address renewed.

QUESTION 8:

A. Establish a Telnet session to Certkingdom -SR34 and then run the net start dhcp
command.
B. Establish a Telnet session to Certkingdom -SR34 and then run the net start dhcpserver
command.
C. Establish a Telnet session to Certkingdom -SR34 and then run the ipconfig /renew
command.
D. On Certkingdom -WS291, run the netsh dhcp server\\ Certkingdom -SR34 show server
command.

Answer: B

Explaination: You can start the DHCP Server service by executing the Net Start
Dhcpserver command at the command prompt.
Telnet is a protocol that enables an Internet user to log on to and enter commands on a
remote computer linked to the Internet, as if the user were using a text-based terminal
directly attached to that computer. Telnet is part of the TCP/IP suite of protocols. The
term telnet also refers to the software (client or server component) that implements this
protocol.
Given the fact that you can ping Certkingdom -SR34 you should then establish a Telnet
session to Certkingdom -SR34 and then run the appropriate command.

QUESTION 9:

A. Run the net session command.
B. Run the netstat command.
C. Run the netsh command.
D. Run the netcap command.

Answer: D

Explaination: Netstcap.exe is a command line tool that could be used to capture the
network traffic. A filter can be created to be used during the capture to determine the
MAC address the print jobs are being sent to. The Network Monitor Capture Utility (
Netcap.exe) can be used to capture network traffic in Network Monitor. Netcap provides
capture abilities only from a command prompt; to open the resulting capture (.cap) files,
you must use the full Network Monitor interface. Netcap is installed when you install the
Support tools that are on the Windows XP CD-ROM. Netcap provides capture abilities
that are similar to the version of Network Monitor that is included with the Windows
Server products; however, you must use Netcap at a command prompt. Netcap installs
the Network Monitor driver and binds it to all adapters when you first run the Netcap
command.
Incorrect Options:
A: The net session command can be used to view the computer names and user names of users
on a server, to see if users have files open, and to see how long each user’s session has
been idle. Net session manages server computer connections – used without parameters,
net session displays information about all sessions with the local computer.
B: The netstat command is not a utility to use when troubleshooting NetBIOS names, but
is used to show what ports your computer is listening on.: -R is used to reload your
LMHOSTS file located in %systemroot%\system32\drivers\etc., -r will show you which
name resolutions have been answered via broadcasts, and which have been answered via
a NetBIOS name server, -RR switch of the command utility refreshes your NetBIOS
name with a configured WINS server.
C: The Network Shell utility (Netsh.exe) can perform a wide range of system
configuration tasks. You can use commands in the Netsh Interface IP context to
configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and
WINS servers) and to display configuration and statistical information.

QUESTION 10:

Network Topology Exhibit:

LAN Settings Exhibit:

You work as the network administrator at Certkingdom.com The Certkingdom.com
network consists of a single Active Directory domain named Certkingdom.com All
servers on the Certkingdom.com network run Windows Server 2003 and all client
computers run Windows XP Professional. The Certkingdom.com network contains a
Microsoft Internet Security and Acceleration (ISA) Server computer named
Certkingdom -SR01, a DNS server named Certkingdom -SR02, a DHCP server named
Certkingdom -SR03, a file server named Certkingdom -SR21, and a Web server named
Certkingdom-SR25. Certkingdom -SR25 also serves as a central antivirus server.
Certkingdom -SR21 is located on the 10.10.11.0 subnet and Certkingdom -SR25 is
located in the perimeter network. Certkingdom -SR21 contains antivirus software
that checks for new virus definitions on Certkingdom -SR25 every hour. You can also
access Certkingdom -SR25 through a virus update Web page to perform manual
virus definition updates.
Certkingdom -SR03 suffers a catastrophic failure and is removed from the network.
Due to budgetary constraints, a replacement for Certkingdom -SR03 will only be
acquired in the next financial year. You need to redesign network addressing
scheme, and change the IP addresses for Certkingdom -SR01 to the addresses shown
in the Network Topology exhibit.
Certkingdom -SR02 contains the new host (A) resource records for
Certkingdom -SR01.
You receive reports about a new virus threat and want to protect the network
immediately by manually downloading the new virus definitions to
Certkingdom -SR21. you log on to Certkingdom -SR21 but discover that you cannot
access the virus update Web page on Certkingdom -SR25. The static TCP/IP
configuration on Certkingdom -SR21 uses Certkingdom -SR02 as the preferred DNS
server.
You confirm that Certkingdom -SR01 is configured properly. On Certkingdom -SR21,
you view the Internet Explorer LAN settings that are shown in the LAN Settings
exhibit.
What should you do to allow Certkingdom -SR21 to connect to Certkingdom -SR25?

A. At a command prompt on Certkingdom -SR21, run the ipconfig /flushdns command.
B. In the LAN settings of Internet Explorer on Certkingdom -SR21, select the
Automatically detect settings check box.
C. At a command prompt on Certkingdom -SR01, run the ipconfig / flushdns command.
D. At a command prompt on Certkingdom -SR01, run the ipconfig /registerdns command.

Answer: A

Explaination: Running the ipconfig /flushdns command will flush and reset the DNS
resolver cache which is necessary to allow connection. Run this command on
Certkingdom -SR21 to connect to Certkingdom -SR25.
Incorrect Answers:
B: Selecting the “Automatically detect settings” checkbox is not going to allow
Certkingdom -SR21 to connect to WWW.
C: The ipconfig /flushdns command flushes and resets the DNS resolver cache. This is
not what is necessary.
D: The ipconfig /registerdns command refreshes all DHCP leases and registers any related
DNS names. This option is available only on Windows 2000 and newer computers that
run the DHCP Client service. This is not going to allow Certkingdom -SR21 to connect to
WWW when it is run on Certkingdom -SR01.

QUESTION 11:

You log on to a client computer named Certkingdom -WS292 and run the ipconfig
/renew command successfully.
What should you do to ensure that Certkingdom -WS291 can receive its IP address
configuration from the Certkingdom -SR25?

A. Restart the DHCP service on Certkingdom -SR25.
B. Restart Certkingdom -WS291.
C. Restart Certkingdom -SR25.
D. Add additional IP addresses to the scope on Certkingdom -SR25.

Answer: B

Explaination: It is probable that the TCP/IP stack has a problem because the
computer is unable to send a DHCP discover broadcast packet. This can happen
when you insert a network cable after the PC has been started. You should restart
the client PC to successfully obtain a new IP address.
Incorrect Answers:
A, C, D: This is unnecessary because Certkingdom -WS292 did obtain an IP address from
the DHCP server, thus indicating that the DHCP server configuration is not the issue.

QUESTION 12:

You work at headquarters. A Certkingdom.com employee named Andy Booth is one of
three employees that are relocated to headquarters from the Dallas office. Andy
Booth uses a portable client computer named Certkingdom -WS291. Andy Booth
complains that when he plugs Certkingdom -WS291 into the LAN connection in his
new cubicle, he cannot connect to network resources on the LAN or the Internet.
None of the other employees are experiencing the same problem.
When you run the ipconfig command from a command prompt on
Certkingdom -WS291, you see the output as shown in the exhibit.

What should you do to allow Certkingdom -WS291 to connect to network resources
on the LAN or the Internet?

A. Configure Certkingdom -WS291 with a subnet mask of 255.255.240.0.
B. Configure Certkingdom -WS291 with a default gateway of 192.168.3.12.
C. Configure Certkingdom -WS291 with a primary DNS suffix of Certkingdom.com
D. Configure Certkingdom -WS291 to automatically lease an IP address from
Certkingdom -SR01.

Answer: D

Explaination: The client computers on the subnet use DHCP to obtain their IP
configurations. Certkingdom -WS291 has a static IP address, and therefore cannot
obtain a valid IP configuration from the DHCP server.
Incorrect Answers:
A: By changing the subnet mask you will not ensure that Certkingdom -WS291 will
connect to other computers and the Internet.
B: Changing the default gateway will not enable Certkingdom -WS291 LAN connection.
Besides, 192.168.3.12 is the IP address of the DHCP server.
C: Adding a primary DNS suffix means that only domain names listed in that window
will be tried for resolution purposes. Both the connection-specific and primary DNS
suffix are ignored.

QUESTION 13:

A. Reconfigure Internet Connection Sharing on Certkingdom -WS291.
B. Configure the shared dial-up connection on Certkingdom -WS291 so that automatic
dialog is enabled.
C. Configure Certkingdom -WS292 to receive an IP lease from a DHCP server.
D. Configure Certkingdom -WS292 to use Certkingdom -WS291 for DNS name resolution.

Answer: C.

Explaination: The problem is most likely caused by an incorrect or non-existent
default gateway setting on Certkingdom -WS292. If you configure
Certkingdom -WS292 to use DHCP to obtain IP addressing information,
Certkingdom -WS292 will receive the correct settings from the ICS service on
Certkingdom -WS291.
Incorrect Answers:
A: The question refers to a shared dial-up connection on Certkingdom -WS291 not
working. If the dial-up connection is shared, then Internet Connection Sharing is enabled
already.
B: The question states that Certkingdom -WS291 automatically connects to the network at
the main office whenever the user on Certkingdom -WS291 attempts to access resources
located on the main office network. This indicates that automatic dial-up is already
configured.
D: Certkingdom -WS291 is not a DNS server. The ICS service has a DNS proxy that
would pass DNS requests to whichever DNS server Certkingdom -WS291 is using.

QUESTION 14:

A. On Certkingdom -SR25, configure Conflict detection attempts to 1.
B. On Certkingdom -SR25, configure Conflict detection attempts to 3.
C. On Certkingdom -SR25, configure client reservations for each client computer’s MAC
address.
D. On Certkingdom -SR25, activate and reconcile the scopes.

Answer: A

Explaination: When conflict detection attempts are set, the DHCP server uses the
Packet Internet Groper (ping) process to test available scope IP addresses before
including these addresses in DHCP lease offers to clients. A successful ping means
that the IP address is in use on the network. This results in the DHCP server not
offering to lease the address to a client.
If the ping request fails and times out, it indicates that the IP address is not in use on the
network. In this case, the DHCP server offers to lease the address to a client. Each
additional conflict detection attempt delays the DHCP server response by a second while
waiting for the ping request to time out. This in turn increases the load on the server. A
value of no greater than two (2) is recommended for ping attempts.
Incorrect Answers:
B: Due to the latency involved in ping attempts, the higher the conflict detection value is
set, the longer the lease process will be for every client that uses the DHCP server.
C: Configuring client reservations for each client computer MAC address will involve a
physical visit to each and every client computer if you do not ping it successfully.
D: The scope would already be activated in this scenario.

QUESTION 15:

A. On Certkingdom -SR31, modify the Dynamically update DNS A and PTR records only
if requested by the DHCP clients option.
B. On Certkingdom -SR38, modify the Always dynamically update DNS A and PTR
records option.
C. On Certkingdom -SR31, modify the Discard A and PTR records when lease is deleted
option.
D. On Certkingdom -SR31, modify the Dynamically update DNS A and PTR records for
DHCP clients that do not request dynamic updates (for example, clients running
Windows NT 4.0) option.

Answer: D

Explaination: Dynamically Update DNS A And PTR Records For DHCP Clients That
Do Not Request
Updates – This checkbox lets you handle these older clients graciously by making the
updates using a separate mechanism. When checking this check box you will ensure that
Certkingdom -SR38can resolve FQDNs for all client computers on the network under the
given circumstances and the role that Certkingdom -SR31 plays.
Incorrect Answers:
A: Dynamically Update DNS A And PTR Records Only If Requested By The DHCP
Clients – This radio button (which is on by default) tells the DHCP server to register the
update only if the DHCP client asks for DNS registration. When this button is active,
DHCP clients that aren’t hip to DDNS won’t have their DNS records updated. However,
Windows 2000, XP, and Server 2003 DHCP clients are smart enough to ask for the
updates.
B: Always Dynamically Update DNS A And PTR Records – This radio button forces the
DHCP server to register any client to which it issues a lease. This setting may add DNS
registrations for DHCP-enabled devices that don’t really need them, like printer servers;
however, it allows other clients (like Mac OS, Windows NT, and Linux machines) to
have their DNS information automatically updated. This is not what is required.
C: Discard A And PTR Records When Lease Is Deleted – When a DHCP lease expires,
what should happen to the DNS registration? Obviously, it would be nice if the DNS
record associated with a lease vanished when the lease expired; when this checkbox is
checked (as it is by default), that’s exactly what happens. If you uncheck this box, your
DNS will contain entries for expired leases that are no longer valid; when a particular IP
address is reissued on a new lease, the DNS will be updated, but in between leases you’ll
have incorrect data in your DNS-always something to avoid.
