SAA-C03 Question 422
Single answerA media company stores large volumes of video files in Amazon S3. These files are infrequently accessed after the first 30 days but must be retained for at least five years for compliance purposes. The company wants to optimize storage costs while ensuring the files remain easily accessible when needed. What is the MOST cost-effective solution?
- A
Use Amazon S3 Intelligent-Tiering for all files.
- B
Move the files to the S3 Standard-IA storage class after 30 days.
- C
Use S3 Lifecycle policies to transition the files to S3 Glacier Flexible Retrieval after 30 days.
- D
Use S3 Lifecycle policies to transition the files to S3 Glacier Deep Archive after 30 days.
Show answer and explanation
Correct answer: B
Explanation
The media company's files are accessed infrequently after 30 days but must remain accessible on-demand for compliance. S3 Standard-IA provides a cost-effective solution for this use case by reducing storage costs while still allowing fast retrieval when needed. The other options either fail to meet the access requirements or are not the most cost-effective choice for the given access pattern.
- A. Incorrect.
Amazon S3 Intelligent-Tiering automatically moves objects between access tiers based on usage patterns, but it may not be the most cost-effective solution for objects with predictable access patterns, such as those accessed less frequently after 30 days.
- B. Correct.
S3 Standard-IA is a good fit for objects that are accessed infrequently but require rapid access when needed. Transitioning the files to Standard-IA after 30 days aligns with the storage requirements and optimizes costs.
- C. Incorrect.
S3 Glacier Flexible Retrieval is designed for long-term archival storage and is not suitable for objects that may require frequent or immediate access.
- D. Incorrect.
S3 Glacier Deep Archive is the lowest-cost storage class, but it is intended for rarely accessed data with retrieval times of 12 hours or more, which does not meet the accessibility requirements of the media company.
