AWS Certified Cloud Practitioner — Question 967

Which type of AWS storage is ephemeral and is deleted when an Amazon EC2 instance is stopped or terminated?

Answer options

• A. Amazon Elastic Block Store (Amazon EBS)
• B. Amazon EC2 instance store
• C. Amazon Elastic File System (Amazon EFS)
• D. Amazon S3

Correct answer: B

Explanation

An Amazon EC2 instance store provides temporary (ephemeral) block-level storage physically attached to the host computer, which is wiped when the instance is stopped or terminated. Conversely, Amazon EBS, Amazon EFS, and Amazon S3 are persistent storage options that retain data independently of the EC2 instance's state.
