VCP-VCF Administrator 2024 Question 346
Select 3A VMware Cloud Foundation administrator manages a vSAN cluster and discovers that one of the disk groups in a host has failed due to a physical disk controller failure. The administrator needs to recover the vSAN cluster and ensure data availability. Which of the following actions should the administrator take to properly recover from this failure?
- A
Replace the failed disk controller and rebuild the affected disk group.
- B
Remove the affected host from the vSAN cluster and perform a full reconfiguration.
- C
Mark the failed disk group as absent and allow vSAN to rebuild the data elsewhere in the cluster.
- D
Replace the failed components and use the 'Repair Objects Immediately' option in vSAN Health Service.
- E
Check the vSAN Compliance status to ensure object compliance after recovery.
Show answer and explanation
Correct answers: A, D, E
Explanation
To recover from a disk or controller failure in a vSAN cluster, the administrator must replace the failed hardware components and initiate the data repair process to restore redundancy and compliance. It is critical to also verify the compliance status to ensure proper recovery. Unnecessary actions, such as removing the entire host, are not required with vSAN’s built-in recovery mechanisms.
- A. Correct.
Replacing the failed disk controller and rebuilding the affected disk group is a necessary step to recover from a physical controller or disk failure. This restores the physical hardware functionality.
- B. Incorrect.
Removing the entire host and reconfiguring the cluster is not necessary in this scenario. vSAN can recover data availability using its built-in mechanisms without requiring such a drastic step.
- C. Incorrect.
Marking the disk group as absent is not a manual process. vSAN automatically handles absent or degraded components and initiates data rebuilding on its own, where possible.
- D. Correct.
Replacing the failed components and using the 'Repair Objects Immediately' option ensures that vSAN initiates an immediate data repair process for any affected objects, restoring data redundancy and compliance.
- E. Correct.
Checking the vSAN Compliance status ensures that all objects are compliant with the storage policy after the recovery process. This is a best practice for ensuring the cluster is fully operational.
