AWS Certified SysOps Administrator – Associate (legacy) — Question 437

EBS (Elastic Block Store) can be best described as:

Answer options

• A. persistent internet storage.
• B. persistent block storage.
• C. transient instance storage.
• D. transient block storage.

Correct answer: B

Explanation

EBS (Elastic Block Store) provides persistent block-level storage volumes for use with EC2 instances, ensuring data remains intact even if the associated instance is stopped or terminated. In contrast, instance store volumes offer transient (ephemeral) storage, and internet or object storage solutions like S3 do not operate as standard block storage devices.
