VCP-VCF Administrator 2024 Question 169
Single answerYou are managing a virtual machine in a VMware Cloud Foundation environment that is experiencing performance issues. After investigating, you discover that multiple snapshots of the VM have been taken over time, and their sizes have significantly grown. What is the best course of action to resolve the snapshot-related performance degradation while preserving critical data?
- A
Delete all snapshots immediately to free up disk space.
- B
Consolidate the snapshots to merge their data into the base disk.
- C
Create a new snapshot before deleting the old ones to preserve the VM state.
- D
Revert the VM to the oldest snapshot to restore its performance.
Show answer and explanation
Correct answer: B
Explanation
When managing snapshots in VMware Cloud Foundation, performance issues can arise due to multiple or large snapshots. The best practice is to consolidate snapshots, which merges the snapshot data back into the base disk, ensuring data integrity and improving performance. Deleting snapshots without consolidation or creating additional snapshots would not resolve the issue, and reverting to an old snapshot could result in loss of recent data.
- A. Incorrect.
Deleting all snapshots immediately without consolidation may lead to data loss and inconsistencies, especially if the VM is actively using data from the snapshots.
- B. Correct.
Consolidating snapshots merges the data from the snapshots into the base disk, freeing up disk space and addressing performance issues without risking data loss. This is the correct approach.
- C. Incorrect.
Creating a new snapshot before deleting the old ones does not address the performance degradation and further increases disk space usage.
- D. Incorrect.
Reverting to the oldest snapshot would discard all current data and changes made since the snapshot was taken, which is not appropriate unless data recovery to that specific point is required.
