Your network contains an active directory domain named Contoso.com. The domain contains a server named
Server1 that runs Windows Server 2012 R2 and has the Hyper-V server role installed. You have a virtual
machine named VM1. VM1 has a snapshot. You need to modify the Snapshot File Location of VM1.
What should you do first?

A.
Copy the snapshot file

B.
Pause VM1

C.
Shut down VM1

D.
Delete the snapshot

Explanation:
Snapshot data files are stored as .avhd files. Taking multiple snapshots can quickly consume storage space. In
the first release version of Hyper-V (KB950050) and in Hyper-V in Windows Server 2008 Service Pack 2,
snapshot, snapshot data files usually are located in the same folder as the virtual machine by default. In HyperV in Windows Server 2008 R2, the files usually are located in the same folder as the virtual hard disk. The
following exceptions affect the location of the snapshot data files: If the virtual machine was imported with
snapshots, they are stored in their own folder. If the virtual machine has no snapshots and you configure the
virtual machine snapshot setting, all snapshots you take afterwards will be stored in the folder you specify.
Caution
Do not delete .avhd files directly from the storage location. Instead, use Hyper-V Manager to select the virtual
machine, and then delete the snapshots from the snapshot tree. Do not expand a virtual hard disk when it is
used in a virtual machine that has snapshots. Doing so will make the snapshots unusable.
