SAA-C03 Question 412
Single answerYour company stores critical data in an Amazon S3 bucket for analytics. Compliance requirements mandate that data older than 90 days must be archived to reduce costs, and data older than 1 year must be deleted. How can you implement this requirement efficiently while minimizing management overhead?
- A
Use Amazon S3 Lifecycle policies to transition data to Amazon S3 Glacier after 90 days and delete it after 1 year.
- B
Manually move data older than 90 days to Amazon S3 Glacier and delete objects older than 1 year using an AWS CLI script.
- C
Use Amazon S3 Lifecycle policies to transition data to Amazon S3 Standard-IA after 90 days and delete it after 1 year.
- D
Configure an AWS Lambda function to monitor object age and move data to Amazon S3 Glacier after 90 days, and delete it after 1 year.
Show answer and explanation
Correct answer: A
Explanation
Amazon S3 Lifecycle policies are a native feature designed to manage object lifecycles efficiently. By configuring a policy, you can automatically transition data to lower-cost storage classes like S3 Glacier and delete objects after a specified period, meeting both cost-optimization and compliance requirements without manual intervention. This is the most efficient and reliable solution for the given scenario.
- A. Correct.
Correct: Amazon S3 Lifecycle policies allow you to automate the transition of objects to lower-cost storage classes (e.g., S3 Glacier) and eventual deletion. This approach minimizes management overhead and fulfills the compliance requirements.
- B. Incorrect.
Incorrect: Manually moving data and deleting objects via scripts involves significant management effort and is prone to errors. AWS provides built-in lifecycle management to automate such tasks.
- C. Incorrect.
Incorrect: While transitioning to S3 Standard-IA reduces costs, it does not comply with the requirement to archive data in S3 Glacier after 90 days. S3 Glacier is more cost-effective for long-term archival.
- D. Incorrect.
Incorrect: Using an AWS Lambda function for this task is overly complex and unnecessary, as S3 Lifecycle policies are specifically designed for these types of automated transitions and deletions.
