2V0-21.23 Question 374
Select 3A VMware administrator is managing a virtual machine (VM) that runs a critical application. Before performing a complex software upgrade, the administrator decides to take a snapshot of the VM. Which of the following considerations must the administrator take into account when creating and managing VM snapshots?
- A
Snapshots should be deleted as soon as the upgrade is verified to prevent performance degradation.
- B
A snapshot can replace a full backup for long-term data protection.
- C
Snapshots preserve the VM's state, including memory and disk, at the time the snapshot is taken.
- D
Having multiple snapshots can cause datastore performance issues if not managed properly.
- E
Snapshots are automatically deleted after 30 days to save storage space.
Show answer and explanation
Correct answers: A, C, D
Explanation
VMware snapshots are a valuable tool for capturing the state of a virtual machine before making changes, such as software upgrades. However, they are not a long-term solution and should be managed carefully to avoid performance and storage issues. Understanding the limitations and best practices for snapshots is critical for effective VM management.
- A. Correct.
Correct: Snapshots should be deleted as soon as they are no longer needed because they can consume significant storage and degrade performance over time.
- B. Incorrect.
Incorrect: Snapshots are not a replacement for backups. They are intended for short-term use, not long-term data protection.
- C. Correct.
Correct: Snapshots preserve the state of the VM, including memory, disk, and power state, at the time of creation. This allows the VM to be rolled back to this state if needed.
- D. Correct.
Correct: Having multiple snapshots can negatively impact datastore performance and storage consumption, especially if snapshots grow over time.
- E. Incorrect.
Incorrect: Snapshots are not automatically deleted by default. They must be manually managed and deleted by the administrator.
