VMware App Volumes Specialist (2021) — Question 45

An architect is working with vSAN and setting the fault domains to support FTT=1.
How many fault domains will be needed?

Answer options

• A. 2
• B. 3
• C. 4
• D. 1

Correct answer: B

Explanation

For FTT=1, vSAN requires at least three fault domains to ensure that one copy of the data can remain available if one fault domain fails. While one fault domain is insufficient, and two would not provide the necessary redundancy, three fault domains allow for data protection and availability.
