AWS Certified SysOps Administrator – Associate — Question 27

A SysOps administrator configured AWS Backup to capture snapshots from a single Amazon EC2 instance that has one Amazon Elastic Block Store (Amazon
EBS) volume attached. On the first snapshot, the EBS volume has 10 GiB of data. On the second snapshot, the EBS volume still contains 10 GiB of data, but 4
GiB have changed. On the third snapshot, 2 GiB of data have been added to the volume, for a total of 12 GiB.
How much total storage is required to store these snapshots?

Answer options

Correct answer: B

Explanation

The correct answer is B because AWS Backup uses incremental snapshots. The first snapshot requires 10 GiB, the second snapshot only needs the changes (4 GiB), and the third snapshot contains 2 GiB of new data. Therefore, the total is 10 GiB + 4 GiB + 2 GiB = 16 GiB. Options A, C, and D do not accurately account for how incremental snapshots work.
