SAA-C03 Question 380
Single answerA company is looking to optimize its storage costs for a new data analytics solution. The solution requires storing raw data for analytics in a durable and cost-effective manner. The data will be accessed infrequently for processing but must remain immediately accessible when needed. Which storage solution is the most cost-optimized for this use case?
- A
Amazon S3 Standard Storage
- B
Amazon S3 Intelligent-Tiering
- C
Amazon S3 Standard-IA (Infrequent Access)
- D
Amazon S3 Glacier Flexible Retrieval
Show answer and explanation
Correct answer: C
Explanation
Amazon S3 Standard-IA is the most cost-optimized solution for storing data that is infrequently accessed but still requires immediate retrieval. It provides lower storage costs than S3 Standard and avoids the retrieval delays associated with archival storage like S3 Glacier. While S3 Intelligent-Tiering can also optimize costs, it introduces additional monitoring fees that are unnecessary if the access patterns are already well understood.
- A. Incorrect.
Amazon S3 Standard Storage is designed for frequently accessed data, and its cost is higher compared to storage classes optimized for infrequent access. This is not the best option for cost optimization when the data is accessed infrequently.
- B. Incorrect.
Amazon S3 Intelligent-Tiering automatically moves data between tiers but incurs additional monitoring fees, which may not be necessary if you already know the data access pattern is infrequent. While it optimizes costs for unknown or changing access patterns, it is not the most cost-effective for this scenario.
- C. Correct.
Amazon S3 Standard-IA (Infrequent Access) is designed for data that is accessed less frequently but needs to remain immediately accessible. It offers lower storage costs compared to S3 Standard and is suitable for the given use case where the data access is infrequent.
- D. Incorrect.
Amazon S3 Glacier Flexible Retrieval is designed for long-term archival storage and is not suitable for data that needs immediate access. Retrieval times can take minutes to hours, making it inappropriate for this use case.
