Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 100

An environment has two VxRail Clusters with this configuration:

VMs on Cluster-A use a policy with FTT = 1 and FTM = Erasure Coding
VMs on Cluster-B use a policy with FTT = 1 and FTM = Mirroring

A 100 GB VM is planned to be vMotioned from Cluster-A to Cluster-B.

How much more vSAN capacity is consumed in Cluster-B than in Cluster-A?

Answer options

Correct answer: D

Explanation

When using Erasure Coding with FTT = 1, the capacity consumed is less than when using Mirroring with the same FTT. In Cluster-A, the 100 GB VM consumes 50 GB, while in Cluster-B, it consumes 100 GB, leading to a difference of 50 GB. However, considering the effective storage utilization and overhead, the actual additional capacity required is 33 GB.
