SAA-C03 Question 421
Single answerA company is migrating its on-premises data to Amazon S3 and wants to minimize costs for storing infrequently accessed data. The company also requires immediate access to data when needed without waiting for retrieval. Which S3 storage class should the company choose?
- A
S3 Standard
- B
S3 Standard-IA (Infrequent Access)
- C
S3 Intelligent-Tiering
- D
S3 Glacier Instant Retrieval
Show answer and explanation
Correct answer: B
Explanation
S3 Standard-IA is the appropriate choice for storing infrequently accessed data while maintaining immediate access. It provides a cost-effective solution by offering lower storage costs compared to S3 Standard, while still delivering the required rapid access to the data. Other options like S3 Intelligent-Tiering and S3 Glacier Instant Retrieval are either unsuitable or introduce unnecessary complexity or costs for this specific use case.
- A. Incorrect.
S3 Standard is designed for frequently accessed data and is more expensive compared to other storage classes optimized for infrequent access. It is not the best choice for cost savings for infrequently accessed data.
- B. Correct.
S3 Standard-IA (Infrequent Access) is designed for data that is accessed less frequently but requires immediate access when needed. It offers lower storage costs compared to S3 Standard, making it the best option for this scenario.
- C. Incorrect.
S3 Intelligent-Tiering automatically moves data between storage tiers based on usage patterns. While it can optimize costs, it may introduce additional monitoring fees and is not strictly necessary for this scenario where the access pattern is already known (infrequent access).
- D. Incorrect.
S3 Glacier Instant Retrieval is designed for archival data that needs millisecond access. However, it is generally used for long-term storage of rarely accessed data rather than data that is infrequently accessed but still active.
