You administer a Windows 10 Enterprise computer that runs Hyper-V. The computer hosts a virtual
machine with multiple snapshots. The virtual machine uses one virtual CPU and 512 MB of RAM.
You discover that the virtual machine pauses automatically and displays the state as paused-critical.
You need to identify the component that is causing the error. Which component should you identify?

A.
no virtual switch defined

B.
insufficient memory

C.
insufficient hard disk space

D.
insufficient number of virtual processors

Explanation:
In this question, the VM has “multiple snapshots” which would use up a lot of disk space. Virtual
machines will go into the “Paused-Critical” state in Hyper-V if the fregfe space on the drive that
contains the snapshots goes below 200MB. One thing that often trips people up is if they have their
virtual hard disks configured on one drive – but have left their snapshot files stored on the system
drive. Once a virtual machine snapshot has been taken – the base virtual hard disk stops expanding
and the snapshot file stores new data that is written to the disk – so it is critical that there is enough
space in the snapshot storage location.
Incorrect Answers:
A: No virtual switch being defined would not cause the Pause-Critical state.
B: Insufficient memory would not cause the Pause-Critical state.
D: An insufficient number of virtual processors would not cause the Pause-Critical state.
