AWS Certified SysOps Administrator – Associate (legacy) — Question 862

A SysOps Administrator stores crash dump files in Amazon S3. New security and privacy measures require that crash dumps older than 6 months be deleted.
Which approach meets this requirement?

Answer options

• A. Use Amazon CloudWatch Events to delete objects older than 6 months.
• B. Implement lifecycle policies to delete objects older than 6 months.
• C. Use the Amazon S3 Standard-Infrequent Access (S3 Standard-IA) storage class to automatically delete objects older than 6 months.
• D. Create versioning rules to delete objects older than 6 months.

Correct answer: B

Explanation

Amazon S3 lifecycle policies allow you to define actions to automatically expire (delete) objects after a specified number of days, making it the most efficient native solution for this requirement. Amazon CloudWatch Events cannot natively manage object expiration, and S3 versioning rules alone do not delete current versions of objects based on age. Transitioning objects to S3 Standard-IA changes their storage tier to save costs but does not delete them.
