AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A healthcare application on AWS archives patient records that need to be retained for a minimum of 7 years for compliance reasons. The current design stores all data on Amazon S3. Which S3 feature should be used to automate the transition of the patient records to a lower-cost storage class after a year, and then ensure deletion after 7 years?
Enable Amazon S3 Intelligent-Tiering to automatically move the data to the most cost-effective storage class.
Configure S3 Replication to replicate the data to a different bucket for storing the data longer and reducing costs.
Implement an Amazon S3 Lifecycle policy to transition the data to S3 Glacier after a year and expire the data after 7 years.
Set up S3 Versioning to make archived versions of the patient records, which could later be manually deleted after 7 years.
Amazon S3 Lifecycle policies enable the automation of moving objects between different storage classes and managing object expiration. Setting a lifecycle policy to transition objects to Amazon S3 Glacier or S3 Glacier Deep Archive after a year takes advantage of lower-cost storage classes suitable for data that is infrequently accessed. Furthermore, another action can be defined in the policy to permanently delete objects after 7 years, thereby adhering to compliance requirements for data retention. Using S3 Versioning or S3 Replication does not automate the process of transitioning data to lower-cost storage classes or object deletion after a specified period. S3 Intelligent-Tiering is a storage class that automatically moves data to the most cost-effective access tier without the need to set lifecycle policies, but it does not ensure deletion after a specified period.
