AWS Certified SysOps Administrator – Associate (legacy) — Question 445

In Amazon EC2, can you create an EBS volume from a snapshot and attach it to another instance?

Answer options

• A. No, you cannot attach EBS volumes to an instance.
• B. Yes, you can but only if the volume is larger than 2TB.
• C. No, you can't create an EBS volume from a snapshot.
• D. Yes, you can.

Correct answer: D

Explanation

Amazon EBS allows you to create a new volume from any existing EBS snapshot and then attach it to any EC2 instance, provided they are in the same Availability Zone. There are no size restrictions like a 2TB minimum for this operation, and creating volumes from snapshots is a fundamental feature of the service.
