VMware App Volumes Specialist (2021) — Question 36

During a planning session for new vSAN clusters in multiple data centers, the customer relayed the following information:
✑ Highest possible mitigation during a host failure in terms of capacity.
✑ A constraint in this year's IT budget.
What should the architect recommend?

Answer options

• A. Enable operations reserve. A minimum cluster of 3 vSAN nodes.
• B. Enable host build reserve. A minimum cluster of 4 vSAN nodes.
• C. Enable performance services. A minimum cluster of 6 vSAN nodes.
• D. Enable IOInsight Metrics. A minimum cluster of 2 vSAN ROBO nodes.

Correct answer: B

Explanation

The correct answer is B because enabling host build reserve with a minimum of 4 vSAN nodes allows for better capacity mitigation during host failures while adhering to budget constraints. Option A does not provide enough nodes for proper resilience, option C exceeds budget considerations with 6 nodes, and option D does not meet the requirements for capacity mitigation in a broader cluster setup.
