VMware App Volumes Specialist (2021) — Question 44

An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local
Protection) configured.
The administrator has been alerted that there is a problem with the cluster. The following has been observed:
✑ The vSAN Witness Host is offline.
✑ Two disk failures on two hosts have occurred in the preferred site.
This has resulted in a critical production virtual machine's vmdk becoming inaccessible.
Which step needs to be performed by the administrator to resolve the issue?

Answer options

• A. Replace all failed disks on the preferred site.
• B. Replace the vSAN Witness Host
• C. Replace access to the existing vSAN Witness Host
• D. Replace only one failed disk on the preferred site.

Correct answer: C

Explanation

The correct action is to replace access to the existing vSAN Witness Host, as the witness is necessary for the cluster to maintain quorum and access to the virtual machine's vmdk. Replacing all failed disks or just one disk does not solve the issue of the offline witness, and simply replacing the witness host may not address the current access problem if the cluster configuration is not restored first.
