VCP-VMC 2024 Question 228
Select 3You are a cloud administrator managing a VMware Cloud environment. A critical virtual machine (VM) is running an application that requires frequent updates. Before applying a major update, you decide to create a snapshot to ensure rapid rollback in case of failure. Which of the following considerations should you follow when creating and managing the snapshot in this scenario?
- A
Do not keep snapshots for an extended period as they can grow in size and impact VM performance.
- B
Power off the VM before creating the snapshot to ensure data consistency.
- C
Use descriptive names for snapshots to identify their purpose and creation date.
- D
Delete snapshots immediately after reverting a VM to avoid storage overhead.
- E
Snapshots are a replacement for regular backups and should be retained indefinitely.
Show answer and explanation
Correct answers: A, C, D
Explanation
When creating and managing snapshots in VMware Cloud environments, it is crucial to follow best practices to ensure efficient storage utilization and VM performance. Snapshots are intended for temporary use, such as testing updates or changes. Long-term reliance on snapshots can cause storage bloat and degrade performance. Descriptive naming and timely deletion of snapshots after use are essential for effective snapshot management. It is also important to remember that snapshots are not substitutes for backups.
- A. Correct.
Snapshots should not be kept for an extended period because they can grow in size, consuming storage and potentially impacting VM performance. This is a best practice for snapshot management.
- B. Incorrect.
Powering off the VM is not necessary for creating snapshots in most cases, as VMware supports creating snapshots for running VMs with memory and disk states. This is not a required consideration for this scenario.
- C. Correct.
Using descriptive names for snapshots helps identify their purpose and creation dates, making it easier to manage and track them in a large environment.
- D. Correct.
After reverting a VM to a snapshot, the snapshot should be deleted to avoid storage overhead and to prevent performance issues caused by excessive snapshot growth.
- E. Incorrect.
Snapshots are not a replacement for backups. They are intended for short-term use and testing scenarios, and retaining them indefinitely can lead to storage and performance problems.
