Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 17

Dell EMC VxRail All-Flash nodes have been deployed in a Stretched Cluster configuration. A storage policy has been configured with:
✑ PFTT = 1
✑ SFTT = 0
✑ FTM = Default
What protection will a VMDK have with this storage policy?

Answer options

• A. RAID 1 cross-site RAID 5 locally
• B. No cross-site protection RAID 1 locally
• C. RAID 1 cross-site RAID 1 locally
• D. RAID 1 cross-site No local protection

Correct answer: A

Explanation

The correct answer is A, as PFTT = 1 indicates that there is one failure tolerance across the sites, which utilizes RAID 1 for cross-site protection. The local RAID configuration defaults to RAID 5, providing additional redundancy locally. The other options incorrectly interpret the protection levels or RAID configurations indicated by the storage policy settings.
