VCP-VCF Administrator 2024 Question 179
Single answerA VMware Cloud Foundation administrator is managing a critical workload that relies on a virtual machine (VM). The administrator decides to delete an existing snapshot of this VM to conserve storage space. What is the immediate impact of deleting the snapshot on the VM and its performance?
- A
The VM will be deleted along with the snapshot.
- B
The snapshot's data will be merged into the parent disk, and the VM's performance may temporarily degrade during the process.
- C
The snapshot will be permanently deleted without affecting the VM's parent disk or performance.
- D
The VM will need to be powered off before the snapshot can be deleted.
Show answer and explanation
Correct answer: B
Explanation
Deleting a snapshot in VMware Cloud Foundation does not delete the VM but instead merges the snapshot's data into the parent disk. This process involves disk I/O operations that can temporarily affect the VM's performance. Understanding this impact is crucial for administrators managing critical workloads to avoid any unexpected performance issues during snapshot operations.
- A. Incorrect.
Incorrect. Deleting a snapshot does not delete the VM associated with it; only the snapshot's data is affected.
- B. Correct.
Correct. When a snapshot is deleted, its data is merged into the parent disk, which can temporarily degrade performance due to disk I/O operations.
- C. Incorrect.
Incorrect. While the snapshot is permanently deleted, its data is merged into the parent disk, which may temporarily impact performance.
- D. Incorrect.
Incorrect. It is not necessary to power off the VM to delete a snapshot; the operation can be performed while the VM is running.
