Dell EMC Specialist – Implementation Engineer, ECS — Question 22

A VxRail Stretched Cluster will be configured with four All-Flash nodes at each site based on the following requirements:
✑ PFTT = 1
✑ SFTT = 1
✑ FTM = Erasure Coding
Based on the required usable capacity, what should be the planned capacity of the design?

Answer options

• A. Single Site Capacity = 150% Total Cluster Capacity = 300%
• B. Single Site Capacity = 133% Total Cluster Capacity = 266%
• C. Single Site Capacity = 100% Total Cluster Capacity = 200%
• D. Single Site Capacity = 200% Total Cluster Capacity = 400%

Correct answer: C

Explanation

The correct answer is C because with PFTT = 1 and SFTT = 1, the usable capacity is designed to be 100% at each site, resulting in a total cluster capacity of 200%. Options A, B, and D overestimate the required capacity based on the specified protection and redundancy levels.
