DEA-C01 Question 244
Select 2Your company is implementing a data retention policy for a data lake built on Amazon S3. The policy states that frequently accessed data should be retained for 1 year, infrequently accessed data should be archived for compliance for an additional 5 years, and data older than 6 years should be permanently deleted. Which combination of S3 features would best meet this requirement?
- A
Use S3 Lifecycle policies to transition data to S3 Glacier Deep Archive after 1 year and delete it after 6 years.
- B
Use S3 Versioning to retain multiple versions of the same object for compliance.
- C
Use S3 Lifecycle policies to transition data to S3 Standard-IA after 1 year, then to S3 Glacier after 5 years, and delete it after 6 years.
- D
Use S3 Intelligent-Tiering to automatically archive infrequently accessed data to S3 Glacier Deep Archive and permanently delete it after 6 years.
- E
Enable S3 Object Lock in compliance mode to automatically transition objects to S3 Glacier after 1 year and delete them after 6 years.
Show answer and explanation
Correct answers: A, C
Explanation
S3 Lifecycle policies are the best solution for implementing data retention policies and archiving strategies because they allow you to define rules for transitioning objects between storage classes and automatically deleting them after a specified time. This aligns with the requirement to manage data retention for cost and compliance. Combining transitions to S3 Standard-IA, S3 Glacier, and eventual deletion after 6 years ensures both cost optimization and compliance.
- A. Correct.
Correct: S3 Lifecycle policies can be used to transition data to different storage classes, such as S3 Glacier Deep Archive, for cost-effective long-term archiving and to delete data after its retention period.
- B. Incorrect.
Incorrect: S3 Versioning retains multiple versions of an object but doesn't help with storage class transitions or deletion based on retention policies.
- C. Correct.
Correct: S3 Lifecycle policies can be configured to transition data first to S3 Standard-IA, then to S3 Glacier, and finally delete it after the specified time, aligning with the retention requirements.
- D. Incorrect.
Incorrect: S3 Intelligent-Tiering is designed for automatic cost optimization based on access patterns but doesn’t allow for scheduled deletion or compliance-specific transitions.
- E. Incorrect.
Incorrect: While S3 Object Lock in compliance mode prevents deletion or modification, it doesn’t automate storage class transitions or deletion based on retention policies.
