HPE Converged Storage Solutions — Question 45

A solution architect is sizing the required capacity for an HPE Alletra 9000. Customer requirements include:

• 200TB base volumes
• Regular snapshots being taken every hour with one-week retention
• 10% daily change rate

How much capacity is needed for snapshots after one week?

Answer options

Correct answer: D

Explanation

The correct answer is D, which accounts for the daily change rate of 10% on the 200TB of base volumes over a week. This results in a snapshot requirement of 140TB after one week, while the other options either underestimate or miscalculate the required capacity based on the daily change rate and retention policy.
