VMware App Volumes Specialist (2021) — Question 43

A cache disk failure marked a vSAN disk group as failed, and the data is being rebuilt on other disk groups.
Which action should the vSAN administrator take to reduce the negative impact on the VMs?

Answer options

• A. Enabling Resync Throttling
• B. Enabling Maintenance mode with no data evacuation
• C. Enabling automatic rebalance
• D. Setting the vSAN policy's IOPS limit for object value to 0 (unlimited)

Correct answer: A

Explanation

Enabling Resync Throttling is the correct action to manage the impact on VMs during the data rebuild process, as it controls the bandwidth used for resynchronization, preventing performance degradation. The other options either do not address the immediate impact on VMs effectively or may worsen the situation by disrupting normal operations or resource allocation.
