SAA-C03 Question 411
Single answerA company stores large volumes of log data in an Amazon S3 bucket. The data is frequently accessed for the first 30 days, after which it is rarely accessed but must be retained for compliance purposes for at least 7 years. Which solution is the MOST cost-effective for managing the data lifecycle while ensuring compliance?
- A
Configure an S3 Lifecycle policy to transition objects to S3 Glacier Instant Retrieval after 30 days and delete them after 7 years.
- B
Manually move objects to S3 Glacier after 30 days and delete them after 7 years.
- C
Configure an S3 Lifecycle policy to transition objects to S3 Standard-IA after 30 days and then to S3 Glacier Deep Archive after 7 years.
- D
Configure an S3 Lifecycle policy to transition objects to S3 Standard-IA after 30 days and then to S3 Glacier Deep Archive after 1 year.
Show answer and explanation
Correct answer: A
Explanation
S3 Lifecycle policies are designed to optimize cost and automate data management. In this scenario, transitioning data to S3 Glacier Instant Retrieval after 30 days ensures cost savings while maintaining fast access for compliance checks. Configuring the policy to automatically delete data after 7 years meets the compliance requirement without manual intervention.
- A. Correct.
This is the correct answer. S3 Lifecycle policies allow you to automate the transition of objects to a lower-cost storage class (S3 Glacier Instant Retrieval) after 30 days and delete them after 7 years, meeting both the cost-effectiveness and compliance requirements.
- B. Incorrect.
This option requires manual intervention, which is not practical or efficient at scale. Additionally, it does not leverage the automation provided by S3 Lifecycle policies.
- C. Incorrect.
This option transitions objects to S3 Standard-IA after 30 days, but transitioning to S3 Glacier Deep Archive after 7 years does not align with the compliance requirement since the data would remain in expensive S3 Standard-IA storage for too long.
- D. Incorrect.
This option transitions objects to S3 Glacier Deep Archive after 1 year, which is unnecessary since the data is only infrequently accessed after 30 days. Transitioning to S3 Glacier Deep Archive earlier would be more cost-effective.
