QUESTION 1
Your company has a private cloud that is managed by using a System Center 2012 infrastructure.
You deploy Data Protection Manager (DPM) to a server named DPM1.
A server named Server1 has the Hyper-V server role installed and hosts a virtual machine named VM1.
From DPM1, you perform a full backup of Server1.
You discover that you are unable to restore idividual files from VM1.
You need to ensure that you can restore individual files from VM1 by using the DPM Administrator console.
What should you do first?
A. On VM1, install Windows Server Backup
B. On DPM1, attach the VHD of VM1
C. On DPM1, install the Hyper-V server role.
D. On VM1, install integration features.
Answer: C
Explanation/Reference:
See here: http://blogs.virtualizationadmin.com/lowe/2011/01/12/hyper-v-and-dpm-watch-out-for-this/
If you’re here, you already know you love virtualization so it’s tempting to, as new services come on board, add them to the virtual environment. But, be careful when you consider adding Data Protection Manager as a virtual service. If you do, you lose the key ability to fully protect Hyper-V-based workloads using DPM’s native Hyper-V hooks. The reason: In order to fully protect Hyper-V with DPM, the DPM server requires that the Hyper-V role be installed on it. You can’t install the Hyper-V role inside a virtual guest due to lack of VT/AMD-V capability inside the VM. Hence, you’re out of luck.
Let’s talk specifics: In short, although you can still protect Hyper-V with a virtual DPM server, on the recovery side, you lose the ability to perform item-level restoration of items from inside a virtual machine.
You can still protect individual virtual machine workloads by installing the DPM agent inside the virtual machine’s guest OS at which point DPM sees that VM as just another system to be protected.
My advice: Just go physical if you’re deploying DPM, especially if you need that native Hyper-V support.
NOTE: The text below was copied from a duplicate question
in either case, DPM utilizes the Hyper-V VSS writer to synchronize block-level differences within the VHDs using
a process called an “Express Full”, which identifies which blocks have changed in the entire VHD and then sends
just the updated blocks or fragments. This provides a complete and consistent image of the virtual hard disk
files on the DPM server or appliance. DPM maintains up to 512 shadow copies of the full VHD set by storing only
the block-level differences between any two images.

QUESTION 2
Your company has a private cloud that is managed by using a System Center 2012 infrastructure.
The infrastructure contains multiple servers that have Data Protection Manager (DPM) installed. A DPM server named Server1 is running out of hard disk space.
You add additional physical hard disks to Server1.
You verify that the additional disks are available from the local Disk Management console.
You need to ensure that the additional disk space can be used to store DPM backups.
What should you ?
A. From the DPM Administrator console, click Refresh.
B. From the DPM Administrator console, click Disk Allocation.
C. From the DPM Administrator console, click Add.
D. From the DPM Administrator console, click Rescan.
Answer: C
Explanation/Reference:
To add disks to the storage pool
In DPM Administrator Console, on the navigation bar, click Management, and then click the Disks tab.
In the Actions pane, click Add.
The Add Disks to Storage Pool dialog box appears. The Available disks section lists the disks that you can add to the storage pool.
Select one or more disks, click Add, and then click OK.

QUESTION 3
Your company has a private cloud that is managed by using a System Center 2012 infrastructure.
An administrator installs a new tape drive on a server that has Data Protection Manager (DPM) installed.
You discover that the tape drive is unavailable from the DPM Administrator console.
You verify that the tape drive is installed correctly on the DPM server.
You need to ensure that the tape drive is available from the DPM Administrator console.
What should you do from the DPM Administrator console?
A. From the Agents view, click Install.
B. From the Disks tab, click Add.
C. From the Protection view, click Tape.
D. From the Libraries view, click Rescan.
Answer: D
