VMware vSphere 6.5 Professional (2017) — Question 13

Assuming a mirrored (RAID-1) object configuration, how many hosts must contribute storage in a non-stretched VMware vSAN cluster to satisfy the "Number of failures to tolerate" policy option? value for all options.

Answer options

• A. 2n+2
• B. 2n
• C. 2n+1
• D. 3n

Correct answer: C

Explanation

The correct answer is C (2n+1) because in a RAID-1 setup, for every piece of data stored, there needs to be a mirror copy, plus one additional host to tolerate the failure. Options A, B, and D do not account for the necessary additional host required for proper mirroring and failure tolerance.
