Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 135

What is the minimum number of nodes needed for self-healing after a failure with a vSAN storage policy of FTT = 1 and FTM = Mirroring?

Answer options

• A. 3
• B. 4
• C. 5
• D. 6

Correct answer: C

Explanation

The correct answer is 5 because with FTT = 1, one copy of the data can be lost, and with mirroring, two copies exist. Therefore, at least 5 nodes are necessary to maintain redundancy and enable self-healing after a node failure. The other options do not provide sufficient nodes to meet the requirements of the specified storage policy.
