Amazon S3 Standard
- B
Amazon S3 Glacier Instant Retrieval
- C

- D
Amazon S3 Standard-IA (Infrequent Access)
Show answer and explanation
Correct answer: D
Explanation
The Amazon S3 Standard-IA storage class is optimized for infrequently accessed data that requires rapid retrieval. It provides lower storage costs compared to S3 Standard while maintaining high performance for retrieval, making it an ideal choice for the company's requirements. Other options either do not meet the cost-saving goal or are not designed for this specific use case.
- A. Incorrect.
Amazon S3 Standard is designed for frequently accessed data, making it more expensive for data that is rarely accessed, which does not meet the company's cost-saving requirement.
- B. Incorrect.
Amazon S3 Glacier Instant Retrieval is primarily designed for archival data that needs to be retrieved instantly. Although it offers low storage costs, it is best suited for archival purposes rather than infrequently accessed data.
- C. Incorrect.
Amazon S3 Intelligent-Tiering automatically moves data between different tiers based on access patterns. However, it is ideal for unpredictable access patterns rather than data that is rarely accessed but needs quick retrieval.
- D. Correct.
Amazon S3 Standard-IA (Infrequent Access) is designed for data that is infrequently accessed but requires quick retrieval when needed. It offers lower storage costs than S3 Standard, making it the appropriate choice for this scenario.
