AWS Certified Cloud Practitioner — Question 530

A company is using a third-party service to back up 10 TB of data to a tape library. The on-premises backup server is running out of space. The company wants to use AWS services for the backups without changing its existing backup workflows.

Which AWS service should the company use to meet these requirements?

Answer options

• A. Amazon Elastic Block Store (Amazon EBS)
• B. AWS Storage Gateway
• C. Amazon Elastic Container Service (Amazon ECS)
• D. AWS Lambda

Correct answer: B

Explanation

AWS Storage Gateway, specifically the Tape Gateway configuration, lets you replace physical tapes with virtual tapes in AWS without altering your existing backup workflows. This allows the company to free up local storage space while continuing to use their third-party backup software. Other options like Amazon EBS, Amazon ECS, and AWS Lambda do not offer tape library emulation or direct integration with on-premises backup servers.
