VMware App Volumes (VCP-AM 2019) — Question 5

A storage administrator discovers vSAN is rebalancing components across a cluster randomly and faces degraded performance on the applications.
What should be done to avoid these issues?

Answer options

• A. Size at least two disk groups on each node
• B. Maintain a minimum of 10 percent unused capacity
• C. Keep total storage consumption <70 percent
• D. Ensure there is sufficient queue depth on the I/O Controller

Correct answer: A

Explanation

The correct answer is A, as having at least two disk groups on each node helps distribute the workload more evenly, reducing the chances of performance degradation during rebalancing. Options B and C focus on capacity management, which is important but does not directly address the rebalancing issue. Option D, while relevant to performance, does not specifically resolve the random rebalancing of components.
