SAP-C02 Question 345
Select 3An e-commerce company is using Amazon S3 to store millions of image files for their product catalog. Most of these files are frequently accessed for the first 30 days after upload, but access patterns significantly drop afterward. The company wants to optimize storage costs while ensuring data is available when needed. Which S3 storage classes and lifecycle configurations should you implement to achieve this goal?
- A
Use S3 Standard storage class for the first 30 days, then transition the objects to S3 Standard-IA storage class after 30 days.
- B
Use S3 Standard storage class for the first 30 days, then transition the objects to S3 Glacier Instant Retrieval storage class after 30 days.
- C
Use S3 Standard storage class for the first 30 days, then transition the objects to S3 Intelligent-Tiering storage class.
- D
Use S3 Intelligent-Tiering storage class with no lifecycle configuration, as it automatically optimizes costs based on access patterns.
- E
Use S3 Standard storage class for the first 30 days, then transition the objects directly to S3 Glacier Deep Archive storage class.
Show answer and explanation
Correct answers: A, C, D
Explanation
To optimize costs for S3 storage, the best approach is to use storage classes and lifecycle configurations that align with the data's access patterns. S3 Standard is suitable for frequently accessed data, but transitioning to more cost-effective classes like S3 Standard-IA or S3 Intelligent-Tiering after the first 30 days ensures cost savings. S3 Intelligent-Tiering is particularly beneficial for dynamically managing costs based on changing access patterns, while S3 Glacier classes are only suitable for long-term archival needs.
- A. Correct.
Correct: Transitioning to S3 Standard-IA after 30 days is a cost-effective solution for infrequently accessed data while maintaining low-latency access.
- B. Incorrect.
Incorrect: S3 Glacier Instant Retrieval is ideal for archival use cases with occasional access, not for scenarios where frequent access is expected even after 30 days.
- C. Correct.
Correct: Transitioning to S3 Intelligent-Tiering after 30 days allows AWS to optimize costs further by automatically moving data to lower-cost tiers as access patterns change.
- D. Correct.
Correct: S3 Intelligent-Tiering automatically optimizes costs without requiring lifecycle rules, making it a viable alternative with minimal management overhead.
- E. Incorrect.
Incorrect: S3 Glacier Deep Archive is designed for long-term archival storage and is not suitable for scenarios where data may need to be accessed within minutes.
