AWS Certified Cloud Practitioner — Question 605

A company needs to store infrequently used data for data archives and long-term backups.

Which AWS service or storage class will meet these requirements MOST cost-effectively?

Answer options

• A. Amazon FSx for Lustre
• B. Amazon Elastic Block Store (Amazon EBS)
• C. Amazon Elastic File System (Amazon EFS)
• D. Amazon S3 Glacier Flexible Retrieval

Correct answer: D

Explanation

Amazon S3 Glacier Flexible Retrieval is specifically designed for archiving data and long-term backups, offering highly durable storage at a fraction of the cost of active storage tiers. In contrast, Amazon EBS, Amazon EFS, and Amazon FSx for Lustre are high-performance block and file storage systems meant for active workloads and are not cost-effective for long-term data archiving.
