SAP-C02 Question 664
Select 2A media company is hosting a large number of video files on Amazon S3. These files are infrequently accessed after their initial upload but must be retained for 5 years to comply with regulatory requirements. The company also wants to minimize storage costs while maintaining the ability to retrieve the files within minutes if needed. Which combination of S3 storage classes and features should be used?
- A
Amazon S3 Glacier Instant Retrieval
- B
Amazon S3 Intelligent-Tiering with the Archive Access Tier enabled
- C
Amazon S3 Standard storage class
- D
Amazon S3 Lifecycle policies to transition objects to S3 Glacier Flexible Retrieval after 30 days
- E
Amazon S3 Lifecycle policies to transition objects to S3 One Zone-IA after 30 days
Show answer and explanation
Correct answers: B, D
Explanation
The combination of Amazon S3 Intelligent-Tiering with the Archive Access Tier enabled and Amazon S3 Lifecycle policies to transition objects to S3 Glacier Flexible Retrieval provides the optimal solution. Intelligent-Tiering minimizes storage costs by dynamically moving objects between tiers based on access patterns. Lifecycle policies ensure that objects are transitioned to the appropriate archival storage class for long-term retention, further reducing costs while meeting retrieval time requirements.
- A. Incorrect.
Amazon S3 Glacier Instant Retrieval is designed for archival data with millisecond retrieval but is more expensive than necessary for infrequently accessed data. It is not optimal for minimizing costs in this scenario.
- B. Correct.
Amazon S3 Intelligent-Tiering is an ideal choice since it automatically moves objects to lower-cost storage tiers based on access patterns. Enabling the Archive Access Tier ensures cost-effective storage for infrequently accessed files while maintaining retrieval within minutes.
- C. Incorrect.
Amazon S3 Standard is the most expensive storage class and is intended for frequently accessed data. It is not suitable for minimizing costs in this scenario.
- D. Correct.
Amazon S3 Lifecycle policies can transition objects to S3 Glacier Flexible Retrieval, which offers lower costs for infrequent access with retrieval times in minutes to hours. This aligns well with the requirements of retaining files for 5 years and minimizing costs.
- E. Incorrect.
Amazon S3 One Zone-IA is a lower-cost option but does not provide the level of durability needed for regulatory compliance, as it stores data in only one Availability Zone. This makes it unsuitable for this scenario.
