VMware App Volumes (VCP-AM 2019) — Question 43

vSAN is configured with a storage policy with a Failures To Tolerate (FTT) set to three.
Which type of redundancy is being used?

Answer options

• A. RAID-0 (Striping)
• B. RAID-1 (Mirroring)
• C. RAID-6 (Erasure Coding)
• D. RAID-5 (Erasure Coding)

Correct answer: B

Explanation

The correct answer is B, RAID-1 (Mirroring), because it is designed to tolerate multiple failures by creating copies of the data. Options A (RAID-0) does not provide redundancy, while both C (RAID-6) and D (RAID-5) offer different forms of erasure coding that tolerate fewer failures compared to RAID-1 with an FTT of three.
