Q7: Which of the following is the responsibility of the customer to ensure the availability and backup of the EBS volumes?

A. Delete the data and create a new EBS volume.
B. Create EBS snapshots.
C. Attach new volumes to EC2 Instances.
D. Create copies of EBS Volumes.

Answer – B

Explanation : 

Snapshots are incremental backups, which means that only the blocks on the device that have changed after your most recent snapshot are saved. 

When you create an EBS volume based on a snapshot, the new volume begins as an exact replica of the original volume that was used to create the snapshot. The replicated volume loads data in the background so that you can begin using it immediately.

Option A is incorrect because there is no need for backup of the volumes if data is already deleted.

Option C is incorrect because attaching more EBS volumes doesn’t ensure availability, if there is no snapshot then the volume cannot be available to a different availability zone.

Option D is incorrect EBS volumes cannot be copied, they can only be replicated using snapshots.
