2V0-21.23 Question 372
Single answerA VMware administrator is tasked with implementing a new backup strategy for their vSphere environment. The solution must ensure that VMs can be restored to their most recent state in case of failure. Additionally, the backup solution must minimize storage consumption and operational overhead. Which approach should the administrator use?
- A
Configure vSphere Replication to replicate VMs to a secondary site.
- B
Use VMware Data Protection (VDP) to create full backups of all VMs nightly.
- C
Leverage vSphere Storage Policy-Based Management (SPBM) to define snapshot-based backups.
- D
Implement a third-party backup solution that supports Changed Block Tracking (CBT).
Show answer and explanation
Correct answer: D
Explanation
The correct approach is to implement a third-party backup solution that supports Changed Block Tracking (CBT). CBT enables incremental backups by only tracking and transferring the changes since the last backup, making it an efficient and modern solution for minimizing storage requirements and operational overhead. Other options either lack backup functionality, are deprecated, or are not suitable for achieving the desired outcome.
- A. Incorrect.
vSphere Replication is primarily used for disaster recovery and replicating VMs to a secondary site, not for creating backups. It does not provide the ability to restore VMs to their most recent state without significant manual effort.
- B. Incorrect.
VMware Data Protection (VDP) is an older backup solution that has been deprecated. While it can create backups, it is no longer the best practice or recommended solution for modern vSphere environments.
- C. Incorrect.
vSphere Storage Policy-Based Management (SPBM) is used for defining storage policies, not for creating or managing backups. Snapshots created via SPBM are temporary and not a substitute for a proper backup solution.
- D. Correct.
Third-party backup solutions with CBT support are specifically designed for efficient backups. CBT ensures only changed data blocks are backed up, reducing storage consumption and operational overhead while allowing restoration to the most recent state.
