VMware App Volumes (VCP-AM 2019) — Question 8

An all-flash vSAN cluster contains four nodes.
Which two storage policies can the cluster satisfy? (Choose two.)

Answer options

• A. FTT=2 (RAID-1 Mirroring)
• B. FTT=2 (RAID-6 Erasure Coding)
• C. FTT=1 (RAID-1 Mirroring)
• D. FTT=1 (RAID-5 Erasure Coding)
• E. FTT=3 (RAID-1 Mirroring)

Correct answer: C, D

Explanation

The correct policies, FTT=1 (RAID-1 Mirroring) and FTT=1 (RAID-5 Erasure Coding), can be satisfied because they require only one failure tolerance, which is feasible with four nodes. Options A, B, and E require higher fault tolerance levels than the cluster can support, making them invalid for this configuration.
