Dell EMC Specialist – Systems Administrator, Elastic Cloud Storage — Question 7
An environment has two VxRail clusters with the following hardware configuration:
✑ Cluster-A is using FTT = 2 and FTM = Erasure Coding
✑ Cluster-B is using FTT = 2 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
- A. 0 GB; consumption is unchanged
- B. 100 GB
- C. 150 GB
- D. 167 GB
Correct answer: D
Explanation
The correct answer is D because when the VM is moved to Cluster-B, the Mirroring FTM requires duplicating the data, effectively consuming more capacity. In contrast, Cluster-A's Erasure Coding uses less capacity due to its method of data protection, leading to a significant difference in capacity consumption between the two clusters.
