AWS Certified Solutions Architect – Associate (SAA-C02) — Question 12

A solutions architect at an ecommerce company wants to back up application log data to Amazon S3. The solutions architect is unsure how frequently the logs will be accessed or which logs will be accessed the most. The company wants to keep costs as low as possible by using the appropriate S3 storage class.
Which S3 storage class should be implemented to meet these requirements?

Answer options

• A. S3 Glacier
• B. S3 Intelligent-Tiering
• C. S3 Standard-Infrequent Access (S3 Standard-IA)
• D. S3 One Zone-Infrequent Access (S3 One Zone-IA)

Correct answer: B

Explanation

S3 Intelligent-Tiering is the most suitable choice because it automatically moves data between two access tiers when access patterns change, which is perfect for uncertain access frequency. The other options, such as S3 Glacier and S3 Standard-IA, are not ideal since they either incur higher retrieval costs or are not designed for unpredictable access patterns.
