AWS Certified Cloud Practitioner (CLF-C02) — Question 225

A company wants to store data in Amazon S3. The company rarely access the data, and the data can be regenerated if necessary. The company wants to store the data in the most cost-effective storage class.

Which S3 storage class will meet this requirement?

Answer options

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

Correct answer: D

Explanation

The correct choice is D, S3 One Zone-Infrequent Access (S3 One Zone-IA), as it is designed for infrequently accessed data and is more cost-effective for data that can be easily recreated. Options A and B are more expensive because they are meant for frequently accessed data, while C, S3 Standard-IA, is also costlier compared to One Zone-IA, which offers lower pricing for data that does not require redundancy across multiple availability zones.
