You are a network administrator for Contoso.com. You have recently upgraded all of your servers to Windows Server 2012 R2. Your manager has indicated that he wants to start testing the live migration feature in a nonclustered environment so that you can eventually take advantage of this functionality in production.
You create a small test network consisting of two Hyper-V servers running Windows Server 2012 R2 named Host1 and Host2. The hardware and software settings on these two physical servers exactly match those of two physical servers in your production network. Host1 is currently hosting a guest VM named VM1.
You enable live migration on both servers and confgure CredSSP as the authentication protocol. You then log on locally to Host1 and initiate a live migration of VM1 from Host1 to Host2. You receive an error message indicating that the VM is using processor-specifc features not supported on the destination physical computer.
You want to perform a live migration successfully in your test network so that you will know what is required to use this feature successfully in production. What should you do?
  • A.
    Confgure constrained delegation for Host1 and Host2.
  • B.
    Disable VM monitoring on VM1.
  • C.
    Confgure Kerberos as the authentication protocol on Host1 and Host2.
  • D.
    On Host1, run the following command:
    Set-VMProcessor VM1 -CompatibilityForMigrationEnabled $true
  • Answer & Explanation
  • Report
Answer : [D]
Explanation :
  • A. Incorrect: Constrained delegation is required for Kerberos authentication. You have confgured CredSSP as the authentication protocol. In addition, you have received an error related to processor compatibility, not authentication.
  • B. Incorrect: VM monitoring isn’t incompatible with live migration, so it wouldn’t generate an error such as this one.
  • C. Incorrect: There is no reason to change the authentication protocol to Kerberos under these circumstances. CredSSP allows you to initiate a live migration when you are logged on locally to the source host.
  • D. Correct: If you enabled processor compatibility on the VM, the virtual processor will use only the features of the processor that are available on all versions of a virtualization-capable processor by the same processor manufacturer. You would see the error described if each host server used a different processor from the same manufacturer.

You are a network administrator for Adatum.com. You have recently upgraded all of your servers to Windows Server 2012 R2. Your manager has indicated that she wants to start testing the live migration feature so that you can eventually take advantage of this functionality in production.
You create a small test network consisting of two Hyper-V servers running Windows Server 2012 R2 named VHost1 and VHost2. The hardware and software settings on these two physical servers exactly match those of two physical servers in your production network. VHost2 is currently hosting a guest VM named VM2.
You enable live migration on both servers and confgure Kerberos as the authentication protocol. You then log on locally to Host1 and initiate a live migration of VM1 from VHost2 to VHost1. The live migration fails, and you receive an error indicating “No credentials are available in the security package.”
You want to perform a live migration successfully in your test network so that you will know what is required to use this feature successfully in production. You also want to initiate live migrations when you are not logged on to the source host server. What should you do next?
  • A.
    Confgure constrained delegation for VHost1 and VHost2.
  • B.
    Disable VM monitoring on VM2.
  • C.
    Confgure CredSSP as the authentication protocol on VHost1 and VHost2.
  • D.
    On VHost1, run the following command:
    Set-VMProcessor VM2 -CompatibilityForMigrationEnabled $true
  • Answer & Explanation
  • Report
Answer : [A]
Explanation :
  • A. Correct: When you choose Kerberos as the authentication protocol, you need to confgure constrained delegation on the computer accounts for the source and destination computers.
  • B. Incorrect: VM monitoring is not incompatible with live migration and would not generate an error such as the one described.
  • C. Incorrect: CredSSP as an authentication protocol would not enable you to initiate live migrations when you are not logged on to the source host server.
  • D. Incorrect: The error received was not related to processor compatibility, so this step would not fx the problem.

You are a network administrator for Proseware.com. One of your servers is named HV1 and is running Windows Server 2012 R2 with the Hyper-V role. HV1 is hosting 10 virtual machines on locally attached storage. It is not a member of any domain.
The available storage used by the 10 guest VMs on HV1 is close to being depleted. At the current rate of growth, the current physical disks attached to HV1 will run out of space in three months.
You want to provide more space to your guest VMs. How can you solve the storage problem with a minimum fnancial expense and minimum impact on users?
  • A.
    Perform a quick migration of the VMs on HV1 to a new server with more space.
  • B.
    Perform a live migration of the VMs on HV1 to a new server with more space.
  • C.
    Perform a storage migration of the VMs on HV1 to a new storage array with ample storage space.
  • D.
    Attach a new storage array with ample storage space to HV1 and expand the VHD fles used by the guest VMs.
  • Answer & Explanation
  • Report
Answer : [C]
Explanation :
  • A. Incorrect: A quick migration is possible only in a failover cluster environment. In addition, purchasing a new server with ample new storage is unnecessarily costly compared to purchasing only new storage.
  • B. Incorrect: You cannot perform a live
    • migration from a computer outside of a domain environment. In addition, purchasing a new server with ample new storage is unnecessarily costly compared to purchasing only new storage.
  • C. Correct: This option avoids the unnecessary expense of purchasing a new server and lets you transfer storage to the new storage array live, without taking your VMs offline.
  • D. Incorrect: This option will not solve your problem. If you purchase a new disk array, you need to fnd a way to move the VMs onto the new storage. You will be able to expand the size of the VHD fles only to the point that they will use up the space on the old disks.

You are a network administrator for Proseware, which has a main offce and a branch offce. The company network consists of a single Active Directory domain, Proseware.com. All servers are running Windows Server 2012 R2 and all clients are running Windows 8.1.
You confgure a fle server at the main offce as a BranchCache content server and confgure two servers at the branch offce as hosted cache servers.
You create a new Group Policy Object (GPO) for the branch offce. Which of the following Group Policy settings do you need to confgure in the GPO to enable the clients at the branch offce to use the hosted cache servers? (Choose all that apply.)
  • A.
    Turn on BranchCache
  • B.
    Set BranchCache Hosted Cache Mode
  • C.
    Enable Hosted Cache Discovery by Service Connection Point
  • D.
    Confgure Hosted Cache Servers
  • Answer & Explanation
  • Report
Answer : [A and D]
Explanation :
  • A. Correct: You need to enable this policy setting to enable BranchCache on clients that fall within the scope of the policy.
  • B. Incorrect: You can use this policy setting to specify only a single hosted cache server.
  • C. Incorrect: You use this policy setting to enable hosted cache discovery. You want to confgure clients with two specifc hosted cache servers, not enable hosted cache discovery.
  • D. Correct: You use this policy setting to confgure clients running Windows 8 or Windows Server 2012 with the names of one or more hosted cache servers.
