VMware App Volumes Specialist (2021) — Question 19

An administrator of `vsan-prod` cluster noticed the witness components of VMs are flagged as absent after a failed attempt to replace the vSAN Witness Host.
Which action should the administrator take to resolve this issue?

Answer options

• A. Upgrading the vSAN on-disk format
• B. Running the vSAN Skyline Health check to ensure there are vSAN Object Health errors and executing the Repair Object Immediately option
• C. Using the RVC command: vsan.resync_dashboard ~/computers/vsan-prod
• D. Placing the vSAN Witness Host in Maintenance Mode and adding to the vSAN cluster

Correct answer: D

Explanation

Placing the vSAN Witness Host in Maintenance Mode and then adding it back to the vSAN cluster allows the system to re-establish connection and synchronize the witness components properly. The other options do not address the issue of the witness components being absent; they either focus on checks or commands that do not directly resolve the absence of the witness components.
