Show answer and explanation
Correct answer: C
Explanation
The S3 Standard-Infrequent Access storage class is designed for data that is accessed less often but still requires immediate retrieval when needed. It provides a lower cost compared to S3 Standard while maintaining high availability. This makes it the best choice for the given scenario where data is rarely accessed but must be immediately available, aligning with the cost optimization goal.
- A. Incorrect.
Amazon S3 Standard is designed for frequently accessed data and offers high availability, but it is not cost-effective for rarely accessed data.
- B. Incorrect.
Amazon S3 Intelligent-Tiering automatically moves objects between access tiers based on usage patterns, but it adds a small monitoring fee and might not be necessary if the access pattern is already known as infrequent.
- C. Correct.
Amazon S3 Standard-Infrequent Access (S3 Standard-IA) is optimized for data that is infrequently accessed but requires immediate retrieval, making it the most suitable and cost-effective choice for this use case.
- D. Incorrect.
Amazon S3 Glacier Instant Retrieval is designed for archival data requiring millisecond retrieval, but it is typically used for long-term archival storage rather than standard infrequent access.
