VMware App Volumes Specialist (2021) — Question 48

An architect intends to use the Primary Level of Failures To Tolerate (PFTT) to calculate the minimum number of required hosts for a vSAN cluster.

Which calculation model should be used?

Answer options

• A. 1 * PFTT + 1
• B. 2 * PFTT + 2
• C. 1 * PFTT + 2
• D. 2 * PFTT + 1

Correct answer: D

Explanation

The correct answer is D, as the calculation for the minimum number of hosts in a vSAN cluster considering PFTT requires accounting for the total number of failures that can be tolerated. Options A, B, and C do not adequately account for the necessary redundancy needed to maintain availability in the event of host failures.
