VMCE Practice Question - 26 February 2025 (VTT)

500. Instant Disk Recovery

You can’t use quick rollback because the data store was unavailable hence b and c are out. d remains correct. Since the VM has multiple disks, Instant Disk Recovery is the most suitable restore method

A - Instant VM Recovery or

D - Instant Disk Recovery

As i don’t know if the VM has only problems within the OS (BSOD) on Disk 1 - imho the best solution should be A. If it’s sure, that only the OS Disk has problems, and the Data on Disk 2 is intact, D would also work.

I go with A

B & C shouldn’t be used, if the error was due to a failure within the Hardware/SAN environment. AS you mentioned, the Datastore was not available.

2. Instant Disk Recovery with Quick Rollback

2. Instant Disk Recovery with Quick Rollback with Disk 1 OS drive 

​​​​A ​​​​​​) Instant VM Recovery 

I would go with D. Instant Disk Recovery for disk 1 (OS)

1. Instant VM Recovery

If have storage issue I think is right way.

So, let’s first knock out 2 options right off the bat → b. and c. Why? Quick Rollback is not an option for any Instant VM operation beit VM or Disk. It is only a restore option for Entire VM or Disk, and when restoring to the original location. Also, you do not use Quick Rollback if there is a VM hardware or some other virtual infrastructure failure. So even if the options were for Entire VM or Disk, we wouldn’t use this feature because the question states there was a Datastore failure.

That leaves either a. or d. And the quickest restore would be to just restore the disk, not entire VM. So d. Instant Disk Recovery is the correct answer here. For more info, see URL below:

I would answer B: Instant Disk Recovery with Quick Rollback
Considering that indeed, there seems to have happened a HW incident (datastore disconnection), that seem to have been a temporal condition, however, that would explain why the VM got a corrupted system file in the first place, but since that condition is corrected (the scenario say that there were datastore disconnections and not that the datastore is currently unavailable), after the datastore is available, we can try an Instant disk recovery with quick roll back to get the best RTO.
