AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An organization wants to automatically move objects that have not been accessed for 30 days to a more cost-effective storage class within Amazon S3, without manual intervention. Which feature should they use to achieve this?
They should configure S3 Lifecycle Rules. S3 Lifecycle Rules allow you to define actions to automatically transition objects to different storage classes based on specified time periods. This helps in optimizing costs by moving less frequently accessed data to cheaper storage classes automatically. Enabling S3 Versioning allows you to keep multiple versions of an object but doesn't manage storage class transitions. Cross-Region Replication replicates objects to another region and is not used for transitioning storage classes within the same bucket. S3 Object Lock helps prevent objects from being deleted or overwritten but does not manage storage class transitions.
