Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 41

A VxRail administrator is evaluating vSAN settings in preparation for vSAN configuration.

Which configurations will result in the lowest initial usable capacity?

Answer options

• A. FTT = 1 (RAID 5 - Erasure Coding) Deduplication and Compression Enabled
• B. FTT = 1 (RAID 5 - Erasure Coding) Deduplication and Compression Disabled
• C. FTT = 1 (RAID 1 - Mirroring) Deduplication and Compression Enabled
• D. FTT = 1 (RAID 1 - Mirroring) Deduplication and Compression Disabled

Correct answer: A

Explanation

Option A will result in the lowest initial usable capacity because RAID 5 with Erasure Coding requires additional space for parity, and enabling Deduplication and Compression further optimizes storage efficiency. The other options either use RAID 1, which requires more capacity for mirroring, or have Deduplication and Compression disabled, which does not maximize space utilization.
