Suggested answer: A

Explanation:

To calculate the required capacity for snapshots after one week for an HPE Alletra 9000 with the given customer requirements:

Base volume size: 200TB

Snapshots frequency: Every hour (24 snapshots per day, 168 per week)

Daily change rate: 10%

The snapshot capacity can be calculated by considering the daily change rate and the number of snapshots over a week.

Daily change: 10% of 200TB = 20TB Total change over a week: 20TB * 7 days = 140TB

Since there are 168 snapshots (24 per day for 7 days), the total required capacity is 140TB (for the changes) plus the base volume size of 200TB, totaling 480TB.
