Dell EMC Specialist – Systems Administrator, Unity XT — Question 6

A customer requests a proposal for a new Dell EMC SC Series storage system with the following specifications:
✑ IO type: Random
✑ Existing data: 100 TB
✑ Rate of change: 2 TB per day
✑ Growth rate: 100 GB per day
✑ Snapshot retention: 1 week
What storage capacity should be specified to scope the system with Tier 1 RAID 10 protection?

Answer options

Correct answer: C

Explanation

The correct answer is 6.5 TB, which accounts for the existing data, the amount of data changing daily, and the growth over a week, all while considering the RAID 10 overhead. The other options do not sufficiently cover the total capacity needed for both the existing and changing data over the specified retention period.
