QUESTION 21
Your network contains a file server named Server1 that runs Windows Server 2008 R2.
Server1 hosts a shared folder that stores Microsoft Excel spreadsheets. A new Excel spreadsheet is created each day.
You need to ensure that all Excel spreadsheets that are older than one month are automatically moved to a different folder.
What should you do?
A. Create an Active Directory Rights Management Services (AD RMS) policy template. B. Create a quota for the shared folder.
C. Create a file management task.
D. Modify the archive attribute of the shared folder.
Correct Answer: C
Section: (none)
Explanation
Explanation/Reference:
Correct answer(s): C
File expiration tasks are used to automatically move all files that match certain criteria to a specified expiration directory, where an administrator can then back those files up and delete them.
When a file expiration task is run, a new directory is created within the expiration directory, grouped by the server name on which the task was run.
The new directory name is based on the name of the file management task and the time it was run. When an expired file is found it is moved into the new directory, while preserving its original directory structure.

QUESTION 22
Your network contains a server named Server1. Server1 has the DHCP server role installed and contains multiple scopes.
You restore the DHCP database and discover that the active IP address leases are not displayed. You need to ensure that all IP address leases are displayed.
What should you do?
A. Reconcile all of the scopes.
B. Run jetpack.exe dhcp.mdb temp.mdb. C. Restart the DHCP Server service.
D. Authorize Server1.
Correct Answer: C
Explanation/Reference:
Correct answer(s): C
Recovery: Restoring DHCP Database from Backup:
If the DHCP server database becomes corrupted or is lost, simple recovery is possible by replacing the server database file (Dhcp.mdb), located in the % SystemRoot %System32Dhcp folder, with a backup copy of the same file. You can then perform a simple file copy to overwrite the current corrupted database with a backup copy of the same file.
If DHCP Manager has been used previously to enable backup, you can obtain the backup copy of the server database file located in the % SystemRoot %System32DhcpBackup folder. As an option, you can also choose to restore the Dhcp.mdb file from a tape backup or other backup media.
Before restoring the database file from backup, the DHCP service must first be stopped. Once you have copied the backup file to the % SystemRoot %System32Dhcp folder from your preferred backup source, you can restart the DHCP service.
To stop the DHCP server service, type the following at a command prompt:
net stop dhcpserver
Once the DHCP service has been stopped, the following procedure can be used to safely restore a backup copy of the database from either backup media or the DHCP service backup folder.
First, move the files from your existing DHCP folder to a different folder location, such as Olddhcp. Be careful to keep the DHCP folder structure intact. For example, type the following set of commands at a command prompt to perform this step:
md c:Olddhcp move % SystemRoot % system32DHCP*.* C:Olddhcp
Next, remove the corrupted server database file. This can also be done at the command prompt:
del % SystemRoot % system32DHCPDhcp.mdb
You can then copy the backup database file into the DHCP service folder. The path to be used when performing the actual copy operation varies (as shown in Table 4.15), depending on the specific server version of Windows running on the computer where the DHCP database file is being restored.

QUESTION 23
Your company has a main office and five branch offices. The branch offices connect to the main office by using a WAN link.
Each branch office has 100 client computers that run Windows XP or Windows Vista. All servers run
Windows Server 2008 R2.
The main office has a Windows Server Update Services (WSUS) server.
You need to minimize the amount of WAN traffic used to download updates from the WSUS server. What should you do?
A. From Windows Explorer, enable Offline Files.
B. From a Group Policy, enable Allow BITS Peercaching.
C. From a Group Policy, enable the Set BranchCache Distributed Cache mode setting. D. From a Group Policy, enable the Set BranchCache Hosted Cache mode setting.
Correct Answer: B
Explanation/Reference:
Correct answer(s): B
Windows Update and Microsoft Update use the Background Intelligent Transfer Service (BITS) to download updates. You can optimize download performance by configuring BITS through Group Policy.
Peer caching is a feature of BITS that enables peer computers to share files. Peer computers are computers that have the peer caching feature enabled and that are located in the same subnet. If peer caching is enabled on a computer, Automatic Updates instructs BITS to make downloaded files available to the computer’s peers.
When updates are downloaded, BITS caches them. When another peer caching-enabled computer tries to download the same update, BITS sends a multicast request to all peers. If peer computers respond to the request, BITS downloads the file from the first peer computer to respond. If the download from the peer computer fails or take too long, BITS continues the download from the WSUS server or from Microsoft Update.
Peer caching can optimize bandwidth in the following ways:
– Decreases the data that is transferred from the WSUS server to client computers because computers in the same subnet will usually download the updates from each other.
– Decreases the data that is transferred across the WAN when some or all of the client computers of a
WSUS server are located in different locations.
– Decreases the data that is transferred across the Internet if WSUS client computers that are located in the same subnet are configured to download updates from Microsoft Update.

QUESTION 24
Your network contains an Active Directory domain. The domain contains two DHCP servers named DHCP1 and DHCP2.
On DHCP1, you create a scope named Scope1.
You configure Scope1 as a split scope and add DHCP2 as an additional DHCP server.
You need to ensure that DHCP1 and DHCP2 can issue IP addresses. What should you do from the DHCP console?
A. Reconcile Scope1 on DHCP2. B. Activate Scope1 on DHCP2.
C. Restart the DHCP Server service on DHCP2. D. Update the range of IP addresses on DHCP1.
Correct Answer: B

QUESTION 25
Your network contains an Active Directory domain named Contoso.com. Contoso.com contains an enterprise certification authority (CA) named CA1.
You enable Secure Socket Tunneling Protocol (SSTP) on a server named Server1.
A user named User1 attempts to establish an SSTP connection to Server1 and receives the following error message: Error 0x80092013: The revocation function was unable to check revocation because the revocation server was offline.
You verify that all certificates services are online.
You need to ensure that User1 can connect to Server1 by using SSTP. What should you do first?
A. Configure a pre-shared key for IPSec on User1s computer.
B. Publish the certificate revocation list distribution point (CDP) to a location that is accessible from the
Internet.
C. Configure User1 for certificate autoenrollment.
D. Add a certificate to Server1 that contains server1.contoso.com as a Subject Alternative Name (SAN).
Correct Answer: B
Explanation/Reference:
Correct answer(s): B
Client tries to connect to SSTP VPN server and it fails to connect giving error message 0x80092013:
Trouble-shooting steps: This will happen if client is failing the certificate revocation check of the SSL certificate obtained from server side. Ensure the CRL check servers on the server side are exposed on the Internet. This is because CRL check is done on the client side during SSL connection establishment phase and the CRL check query will be directly going on the Internet.
