QUESTION 421
Your network contains an Active Directory domain named contoso.com.
The domain contains a server named Server1 that has the Windows Server Update Services (WSUS) server role installed.
You have several client computers that are not members of the domain.
The client computers are currently part of the Unassigned Computers group.
On the client computers, you set the WSUS target group to WSUS_Group1, and then you run wuauclt /resetauthorization / detectnow.
You discover that all of the client computers are still members of the Unassigned Computers group.
You need to ensure that the client computers immediately become members of a computer group named WSUS_Group1.
What should you do? (Each correct answer presents part of the solution. Choose two.)

A.    Create a new WSUS computer group.
B.    On Server1, run wuauclt /resetauthorization /detectnow.
C.    On Server1, create a new security group.
D.    On all of the client computers, run wuauclt /resetauthorization /detectnow.
E.    On Server1, run wsusutil /reset.
F.    On all of the client computers, run wsusutil /reset.

Answer: AD
Explanation:
Note:
– By default, the WSUS server is set to use server-side targeting.
If you are using client- side targeting, you need to set an option on the WSUS server.
– By default, each computer is already assigned to the All Computers group.
Computers will also be assigned to the Unassigned Computers group until you assign them to another group. Regardless of the group you assign a computer to, it will also remain in the All Computers group. A computer can be in only one other group in addition to the All Computers group.

QUESTION 422
You install Microsoft Network Monitor 3.4 on a server.
You start Network Monitor and you capture data overnight.
The next morning, you discover that the server responds very slowly.
You open Task Manager as shown in the exhibit. (Click the Exhibit button.)
You need to reduce the amount of system resources consumed on the server when Network Monitor captures network data.
What should you do?
 

A.    Use Netmon and enable pmode for the network adapter.
B.    Use Netmon with conversations enabled.
C.    Use Nmcap and enable pmode for the network adapter.
D.    Use Nmcap with conversations disabled.

Answer: D

QUESTION 423
Your network contains a Windows Server Update Services (WSUS) server.
You need to ensure that the WSUS server automatically downloads updates for a specific Microsoft product.
What should you do first?

A.    From the Automatic Approvals options, modify the Advanced settings.
B.    From the Products and Classifications options, modify the Classifications settings.
C.    From the Products and Classifications options, modify the Products settings.
D.    From the Automatic Approvals options, modify the Update Rules list.

Answer: B

QUESTION 424
Your network contains an Active Directory domain named contoso.com.
The domain contains a DNS server named Server1.
You are configuring DirectAccess.
You create a static host (A) record for isatap.contoso.com.
You discover that the DNS server fails to respond to queries for the isatap.contoso.com record.
You need to ensure that the DNS server resolves queries for isatap.contoso.com.
What should you do?

A.    Run dnscmd /config /globalqueryblocklist wpad.
B.    Run dnscmd /config /enableglobalqueryblocklist 1.
C.    Create a primary zone for isatap.contoso.com.
D.    Run dnscmd /config /globalqueryblocklist isatap.

Answer: A
Explanation:
Windows 2008 DNS implements GlobalQueryBlockList, an additional security feature that includes ISATAP by default. This causes it to ignore any ISATAP.<domain name> request. Therefore, you must clear ISATAP from the list. Do this via the DNSCMD command or by making a registry entry.
At a command prompt, enter dnscmd /config /globalqueryblocklist wpad and press Enter. This will define the GlobalQueryBlockList as only having WPAD in it (thus removing ISATAP). You also may accomplish this by going to the registry key at HKLM:\System\Current Control Set\Services\DNS\Parameters.
Edit GlobalQueryBlockList and remove ISATAP.

QUESTION 425

You run the nslookup.exe command as shown in the exhibit. (Click the Exhibit button.)
You need to prevent a timeout message from appearing when you run the command.
What should you do?
 

A.    Reload the fabrikam.com zone.
B.    Create a reverse lookup zone.
C.    Run ipconfig /registerdns on www.fabrikam.com.
D.    Restart the Netlogon service on dnsl.fabrikam.com.
E.    Change the fabrikam.com zone to an Active Directory-integrated zone.

QUESTION 427
Your network contains two Active Directory domains named contoso.com and fabrikam.com. Each domain contains several domain controllers.
All of the domain controllers are configured as DNS servers for their respective domain.

QUESTION 428
Your network contains two servers named Server1 and Server2 that run Windows Server 2008 R2 Service Pack 1 (SP1).
Server1 and Server2 have the Network Policy and Access Services (NPAS) server role installed. Server1 is configured as a VPN server. Server1 fails.
You configure Server2 as a VPN server and you configure Server2 to use the external IP address of Server1.
After you configure Server2, users report that they fail to connect to the network by using their PPTP-based VPN connection.

QUESTION 429
Your network contains a server named Server1.
You open Reliability Monitor as shown in the exhibit. (Click the Exhibit button.)
You need to ensure that Reliability Monitor collects and displays information.
Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two.)
 

A.    Start the System Performance Data Collector Set.
B.    Start the System Diagnostics Data Collector Set.
C.    Configure an event viewer subscription.
D.    Modify the RacTask scheduled task.
E.    Modify the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft\Reliability
Analysis\WMI\WMIEnable registry value.

Answer: DE
Explanation:
Issue: When you open Reliability Monitor on a computer that is running Windows Server 2008 or Windows Server 2008 R2, Reliability Monitor displays no information.
Cause: This behavior occurs because the trigger that regularly starts the RacTask task is disabled.
Information that Reliability Monitor displays is provided by the RacTask task. By default, the RacTask task runs one time that is about one hour after you install the operating system.
In Windows Server 2008 and in Windows Server 2008 R2, the trigger that regularly starts the RacTask task is disabled after the RacTask task runs for the first time.
Solution:
To resolve this issue, follow these steps:
– Click Start, type Task Scheduler in the Search box, and then click Task Scheduler.
– Enable the trigger that regularly starts the RacTask task.
– Update a registry setting.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Reliability Analysis\WMI\WMIEnable
– Restart the computer.
Note:
– Reliability Monitor uses data provided by the RACAgent scheduled task. Reliability Monitor will start displaying a Stability Index rating and specific event information 24 hours after system installation.
The RACAgent scheduled task runs by default after the operating system is installed.
If it is disabled, it must be enabled manually from the Task Scheduler snap-in for Microsoft Management Console (MMC).
Reliability Monitor displays no information in Windows Server 2008 and in Windows Server 2008 R2

QUESTION 430
Your network contains a DNS domain named contoso.com.
An administrator installs an FTP server on a server named server2.contoso.com.

Which type of DNS record should you add?
 

A.    text (TXT)
B.    well known service (WKS)
C.    host (A)
D.    pointer (PTR)
E.    service location (SRV)
