DEA-C01 Question 241
Select 2An organization uses Amazon S3 to store large volumes of data for analytics. They want to implement a data retention policy to automatically delete objects after a specific period and transition less frequently accessed data to a lower-cost storage class to optimize costs. Which combination of actions should they take to achieve this?
- A
Create an S3 Lifecycle policy to transition data to Amazon S3 Glacier after a specified number of days.
- B
Enable versioning on the S3 bucket to retain older versions of objects indefinitely.
- C
Create an S3 Lifecycle policy to delete objects after a specified period.
- D
Use S3 Intelligent-Tiering to automatically move data to the most cost-efficient storage class based on access patterns.
- E
Manually move objects to Amazon S3 Glacier Deep Archive for long-term storage.
Show answer and explanation
Correct answers: A, C
Explanation
To implement a data retention policy and optimize costs, S3 Lifecycle policies can be used to transition data to lower-cost storage classes like Amazon S3 Glacier and delete objects after a specified retention period. These actions are automated and align with the organization's requirements, while other options are either unrelated or require manual intervention.
- A. Correct.
Correct: S3 Lifecycle policies allow you to define rules to transition objects to lower-cost storage classes like Amazon S3 Glacier after a specified number of days, helping optimize costs for infrequently accessed data.
- B. Incorrect.
Incorrect: While versioning helps retain older versions of objects, it does not align with implementing a retention policy for automatic deletion or transitioning data to a lower-cost storage class.
- C. Correct.
Correct: S3 Lifecycle policies can also be configured to automatically delete objects after a specified retention period, fulfilling the data retention policy requirements.
- D. Incorrect.
Incorrect: S3 Intelligent-Tiering is useful for optimizing costs based on access patterns, but the question specifically asks for implementing a retention policy with automatic deletion and transition.
- E. Incorrect.
Incorrect: Manually moving objects to Glacier Deep Archive is not an automated process and does not align with the organization's request for an automatic retention and archiving strategy.
