Your network contains a Hyper-V host named Server1 that runs Windows Server 2012. Server1 hosts a virtual
machine named VM1 that runs Windows Server 2012. You take a snapshot of VM1, and then you install an
Application on VM1. You verify that the Applicationruns properly.
You need to ensure that the current state of VM1 iscontained in a single virtual hard disk file.
The solution must minimize the amount of downtime on VM1.
What should you do?
A.
From Hyper-V Manager, delete the snapshot.
B.
From a command prompt, run dism.exe and specify the /commit-image parameter.
C.
From a command prompt, run dism.exe and specify the /delete-image parameter.
D.
From Hyper-V Manager, inspect the virtual hard disk.
Explanation:
Virtual machine snapshots are file-based snapshots of the state, disk data, and configuration of a
virtualmachine at a specific point in time.
You can take multiple snapshots of a virtual machine, even while it is running. You can then revert the virtual
machine to any of the previous states by App1ying asnapshot to the virtualmachine.
Taking a snapshot of a VM is to in essence freeze the current state and make it a parent disk based on
currentstate, and at the same time create a child disk to capture all subsequent changes. – See more at:
Snapshots require adequate storage space. Snapshotsare stored as .avhd files in the same location at
thevirtual hard disk. Taking multiple snapshots canquickly consume a large amount of storage space.
When you use Hyper-V Manager to delete a snapshot, the snapshot is removed from the snapshot treebut the .
avhd file is not deleted until you turn off the virtual machine.
