VCP-VCF Administrator 2024 Question 326
Select 3A VMware Cloud Foundation administrator notices that a virtual machine (VM) backup process fails repeatedly. Upon investigating, it is determined that the error stems from a snapshot issue. The administrator observes that snapshots cannot be deleted or consolidated, and the VM is running slower than normal. What are the most likely causes of this issue?
- A
The datastore hosting the VM has run out of free space.
- B
The snapshot file has grown excessively large and is impacting performance.
- C
The virtual machine is powered off, preventing snapshot consolidation.
- D
The snapshot chain is corrupted due to multiple snapshots being taken and deleted over time.
- E
The ESXi host where the VM resides is in maintenance mode.
Show answer and explanation
Correct answers: A, B, D
Explanation
Snapshot issues can arise from insufficient datastore space, large snapshot sizes, or corrupted snapshot chains. These factors can prevent snapshot deletion or consolidation and degrade VM performance. Understanding these root causes allows administrators to troubleshoot and resolve snapshot-related problems effectively.
- A. Correct.
If the datastore hosting the VM runs out of free space, snapshot operations such as deletion or consolidation can fail. This can also affect VM performance.
- B. Correct.
Excessive growth of snapshot files can consume significant resources on the datastore, impacting the performance of the VM and snapshot operations.
- C. Incorrect.
Snapshots can still be consolidated or deleted while a VM is powered off. The VM's power state is not a factor in this situation.
- D. Correct.
A corrupted snapshot chain can occur when multiple snapshots are taken and deleted over time, leading to potential issues with consolidation or deletion.
- E. Incorrect.
The ESXi host being in maintenance mode does not impact the ability to manage snapshots on a VM, as snapshot operations occur at the VM level and are not directly tied to the host's mode.
