SAP-C02 Question 344
Select 2An e-commerce company stores its product images in an Amazon S3 bucket. These images are frequently accessed for the first 30 days after upload but are rarely accessed afterward. The company wants to optimize storage costs without impacting availability. Which combination of S3 storage classes and features should the company use?
- A
Configure an S3 Lifecycle policy to move objects to S3 Intelligent-Tiering after 30 days.
- B
Use S3 Standard for the first 30 days and transition objects to S3 Glacier Deep Archive afterward.
- C
Configure an S3 Lifecycle policy to transition objects to S3 Standard-IA after 30 days.
- D
Enable S3 Intelligent-Tiering for all objects upon upload.
- E
Configure an S3 Lifecycle policy to transition objects to S3 One Zone-IA after 30 days.
Show answer and explanation
Correct answers: A, C
Explanation
The best solution is to configure an S3 Lifecycle policy to transition objects to cost-effective storage classes based on access patterns. S3 Intelligent-Tiering is suitable for scenarios with unpredictable access patterns, while S3 Standard-IA works well for infrequently accessed objects that require high availability. Using both appropriately ensures cost optimization without impacting data availability or durability.
- A. Correct.
This is a correct option. S3 Intelligent-Tiering is designed to optimize storage costs automatically based on access patterns, and transitioning objects after 30 days can reduce costs effectively when access declines.
- B. Incorrect.
This option is incorrect because S3 Glacier Deep Archive is best suited for long-term archival storage with infrequent retrieval needs. It is not suitable for scenarios requiring consistent availability without retrieval delays.
- C. Correct.
This is a correct option. S3 Standard-IA (Infrequent Access) is a cost-effective option for objects that are rarely accessed but need high availability. Transitioning after 30 days aligns with the access pattern described.
- D. Incorrect.
This option is incorrect because enabling S3 Intelligent-Tiering for all objects upon upload is unnecessary and incurs additional charges for monitoring and automation. A lifecycle policy is more cost-efficient in this scenario.
- E. Incorrect.
This option is incorrect because S3 One Zone-IA stores data in a single Availability Zone, which increases risk. It is not suitable for scenarios where high availability and data durability are required.
