AWS Certified Cloud Practitioner (CLF-C02) — Question 307

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 that does not persist when the host instance is stopped or terminated. In contrast, Amazon EBS, Amazon EFS, and Amazon S3 are persistent storage services designed to retain data independently of the lifecycle of any specific EC2 instance.
