VMware App Volumes 4 Specialist — Question 4

Which storage policy can be assigned to virtual machines in a 5-node, all flash vSAN cluster, to provide the highest level of redundancy?

Answer options

• A. 1 failure "" RAID-5 (Erasure Coding)
• B. 2 failures "" RAID-6 (Erasure Coding)
• C. 2 failures "" RAID-1 (Mirroring)
• D. 3 failures "" RAID-1 (Mirroring)

Correct answer: C

Explanation

The correct answer is C, as RAID-1 (Mirroring) with 2 failures provides a higher level of redundancy compared to the other options. RAID-5 and RAID-6 introduce erasure coding, which may not offer the same level of data availability in scenarios with multiple failures. Option D also provides mirroring, but it is not the most efficient use of resources compared to option C.
