VMware App Volumes Specialist (2021) — Question 5

Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster.
Which two causes explain this behavior? (Choose two.)

Answer options

• A. The cluster DRS threshold has been set to Aggressive.
• B. There is a vSAN node failure.
• C. The vSAN Resync throttling is enabled.
• D. The object repair timer value has been increased.
• E. The vSAN policy protection level has changed from FTT=0 to FTT=1.

Correct answer: B, E

Explanation

A vSAN node failure (option B) can lead to increased backend IOPs due to the need for data reconstruction and redistribution, while changing the vSAN policy protection level from FTT=0 to FTT=1 (option E) will also increase IOPs as more copies of the data need to be maintained. The other options do not directly relate to backend IOPs in the same manner.
