SAA-C03 Question 423
Single answerA company uses Amazon S3 to store large volumes of log files that are rarely accessed but must be retained for compliance purposes for 7 years. The company needs a cost-effective storage solution while ensuring that files can be retrieved within hours if needed. Which S3 storage class should the company use to meet these requirements?
- A
S3 Standard
- B
S3 Intelligent-Tiering
- C
S3 Glacier Flexible Retrieval
- D
S3 Glacier Deep Archive
Show answer and explanation
Correct answer: C
Explanation
S3 Glacier Flexible Retrieval is the best choice for this scenario because it balances cost-effectiveness with relatively fast retrieval times (within hours). This makes it ideal for rarely accessed data that must be retained for compliance purposes but may occasionally need to be retrieved quickly. Other options either do not meet the cost or retrieval time requirements.
- A. Incorrect.
S3 Standard is designed for frequently accessed data and charges a higher storage cost. It is not cost-effective for data that is rarely accessed.
- B. Incorrect.
S3 Intelligent-Tiering automatically moves data between access tiers based on usage patterns, but it incurs monitoring and automation costs, making it less suitable for rarely accessed data with predictable retrieval requirements.
- C. Correct.
S3 Glacier Flexible Retrieval is designed for archival storage with infrequent access. It provides a cost-effective solution for data that requires retrieval within hours, meeting the company's requirements.
- D. Incorrect.
S3 Glacier Deep Archive is the lowest-cost option for archival storage, but its retrieval time is typically in the range of 12-48 hours, which is too long for the company's needs.
