VMware vSphere 8.x Professional (VCP-DCV 2022) — Question 97

An administrator receives an escalation to investigate a low disk space alarm on a datastore. The administrator discovers that a snapshot has been accidentally taken on a production, write-intensive database server. The snapshot has grown to nearly 1 TB in size in less than an hour and continues growing every second.
Which behavior should the administrator expect while deleting the snapshot?

Answer options

• A. ESXi will create a virtual RAM disk to cache ongoing database write activity; performance impact will be limited.
• B. ESXi will commit the snapshot delta disk into the base disk; ongoing database write activity could result in long stun times.
• C. ESXi will merge the snapshot delta disk into the base disk; the virtual machine will be briefly stunned.
• D. ESXi will instantly switch from the base disk to the snapshot delta disk with no performance impact.

Correct answer: B

Explanation

The correct answer is B because during the deletion of a snapshot, ESXi needs to commit the changes from the snapshot delta disk to the base disk, which can lead to long stun times due to ongoing write activity. Option A is incorrect as there will be a performance impact due to the merging process. Option C is not accurate because while there is a brief stun, the emphasis is on the merging process causing potential long stun times rather than a brief one. Option D is incorrect since switching to the delta disk does not happen instantly and will affect performance.
