SAA-C03 Question 82
Single answerA company needs to enforce a data retention policy for its critical business data stored in Amazon S3. The data must be retained for 7 years to meet compliance requirements, and it should be protected against accidental deletion or overwriting during this period. Which solution will meet these requirements?
- A
Enable S3 Versioning and configure a lifecycle policy to transition non-current versions to Glacier after 7 years.
- B
Enable S3 Object Lock in Compliance mode with a retention period of 7 years.
- C
Use S3 Intelligent-Tiering to automatically move objects to the appropriate storage class based on access patterns.
- D
Enable MFA Delete on the S3 bucket and configure a lifecycle policy to delete objects after 7 years.
Show answer and explanation
Correct answer: B
Explanation
To meet the 7-year compliance requirement, the company needs to ensure that the data cannot be deleted or modified for the entire retention period. S3 Object Lock in Compliance mode is specifically designed for this purpose, as it enforces a write-once-read-many (WORM) model that prevents any changes to the data until the retention period expires. Other options, while useful for cost optimization or additional security, do not provide the necessary compliance guarantees.
- A. Incorrect.
This option does not guarantee compliance requirements because lifecycle policies alone cannot enforce a strict retention policy that prevents deletion or modification within a 7-year period.
- B. Correct.
This is the correct answer. S3 Object Lock in Compliance mode ensures that objects cannot be deleted or overwritten for the specified retention period, meeting the 7-year compliance requirement.
- C. Incorrect.
While S3 Intelligent-Tiering optimizes storage costs, it does not enforce a strict data retention policy or prevent accidental deletion or overwriting.
- D. Incorrect.
MFA Delete provides additional protection against accidental deletion but does not enforce a strict, mandatory retention policy for compliance requirements.
