AWS Certified Solutions Architect – Associate (SAA-C02) — Question 121

A company uses Amazon S3 as its object storage solution. The company has thousands of S3 buckets it uses to store data. Some of the S3 buckets have data that is accessed less frequently than others. A solutions architect found that lifecycle policies are not consistently implemented or are implemented partially, resulting in data being stored in high-cost storage.
Which solution will lower costs without compromising the availability of objects?

Answer options

• A. Use S3 ACLs.
• B. Use Amazon Elastic Block Store (Amazon EBS) automated snapshots.
• C. Use S3 Intelligent-Tiering storage.
• D. Use S3 One Zone-Infrequent Access (S3 One Zone-IA).

Correct answer: C

Explanation

The correct answer is C, as S3 Intelligent-Tiering automatically moves data between two access tiers when access patterns change, optimizing costs while maintaining availability. Option A does not address storage costs, but rather access control. Option B pertains to block storage snapshots, which aren't suitable for object storage management. Option D provides lower-cost storage but does not support the same level of availability as Intelligent-Tiering.
