Q9. - (Topic 1)
Your network contains a single Active Directory domain. All servers run Windows Server 2008 R2. A DHCP server is deployed on the network and configured to provide IPv6 prefixes. You need to ensure that when you monitor network traffic, you see the interface identifiers derived from the Extended Unique Identifier (EUI)-64 address.
Which command should you run?
A. netsh.exe interface ipv6 set global addressmaskreply=disabled
B. netsh.exe interface ipv6 set global dhcpmediasense=enabled
C. netsh.exe interface ipv6 set global randomizeidentifiers=disabled
D. netsh.exe interface ipv6 set privacy state=enabled
Answer: C
Explanation:
Starting Windows Vista, Windows Server 2008 and Windows 7, to prevent address scans of IPv6 addresses based on the known company IDs of network adapter manufacturers, Windows by default generate random interface IDs for non-temporary autoconfigured IPv6 addresses, including public and link-local addresses. A public IPv6 address is a global address that is registered in DNS and is typically used by server applications for incoming connections, such as a Web server. However, this can cause issues with some connection instances in which case you may need to disable this option. To prevent Windows from using Random Identifiers,
1. Click Start – search “cmd“, right-click and choose “Run as Administrator“. This should launch the command window withe elevated privileges.
2. Run the following command:
C:windowssystem32> netsh interface ipv6 set global randomizeidentifiers=disabled
At anytime later, you can enable this (if requierd) as follows:
C:windowssystem32> netsh interface ipv6 set global randomizeidentifiers=enabled

Q10. - (Topic 4)
Your network contains a server named Server1.
An administrator named Admin1 installs the Windows Server Update Services (WSUS) server role on Server1.
You open the Windows Server Update Services console and view the Products and Classifications options as shown in the exhibit. (Click the Exhibit button.)
You need to ensure that you can select updates for Windows Server 2008 R2 Service Pack 1 (SP1) from the Products and Classifications options.
What should you do?
A. From a command prompt, run gpudate /force.
B. From the WSUS Administration console, synchronize Server.
C. From the Service console, restart the Update Services service.
D. From a command prompt, run wuauclt /detectnow.
Answer: B
Explanation: * During synchronization, a WSUS server downloads updates (update metadata and files) from an update source. It also downloads any new product classifications and categories. When a WSUS server synchronizes for the first time, it downloads all of the updates that were specified in the synchronization options. After the first synchronization, a WSUS server downloads only updates from the update source, metadata revisions for existing updates, and expirations to updates.
* To specify update products and classifications for synchronization
1. On the WSUS console toolbar, click Options, and then click Synchronization Options. Etc.
