EMC Proven Professional – Elastic Cloud Storage Solutions Expert — Question 11

In a VxRail Stretched Cluster built from eight all-flash nodes, what should be the recommended storage policy to ensure the highest possible protection?

Answer options

• A. Raid-1(Mirroring) FTT=1
• B. Raid-1(Mirroring) FTT=2
• C. Raid-5/6(Erasure Coding) FTT=1
• D. Raid-5/6(Erasure Coding) FTT=2

Correct answer: B

Explanation

The best choice for maximum protection in a VxRail Stretched Cluster is Raid-1(Mirroring) FTT=2 because it provides redundancy by creating two copies of data, allowing for the failure of two nodes without data loss. The other options either offer less protection (FTT=1) or are less effective in a stretched cluster environment where higher fault tolerance is required.
