AWS Certified SysOps Administrator – Associate (legacy) — Question 127

Amazon EBS snapshots have which of the following two characteristics? (Choose two.)

Answer options

• A. EBS snapshots only save incremental changes from snapshot to snapshot
• B. EBS snapshots can be created in real-time without stopping an EC2 instance
• C. EBS snapshots can only be restored to an EBS volume of the same size or smaller
• D. EBS snapshots can only be restored and mounted to an instance in the same Availability Zone as the original EBS volume

Correct answer: A, B

Explanation

The correct answers, A and B, highlight that EBS snapshots store only the changes made since the previous snapshot and can be created while the EC2 instance is running. Options C and D are incorrect because EBS snapshots can be restored to volumes of any size and can be restored across Availability Zones, not limited to the same zone.
