Question
A company runs an application on Amazon EC2 instances across multiple Availability Zones in the same AWS Region. The EC2 instances share an Amazon Elastic File System (Amazon EFS) volume that is mounted on all the instances. The EFS volume stores a variety of files such as installation media, third-party files, interface files, and other one-time files. The company accesses some EFS files frequently and needs to retrieve the files quickly. The company accesses other files rarely. The EFS volume is multiple terabytes in size. The company needs to optimize storage costs for Amazon EFS. Which solution will meet these requirements with the LEAST effort?
Options
- AMove the files to Amazon S3. Set up a lifecycle policy to move the files to S3 Glacier Flexible
- BApply a lifecycle policy to the EFS files to move the files to EFS Infrequent Access.
- CMove the files to Amazon Elastic Block Store (Amazon EBS) Cold HDD Volumes (sc1).
- DMove the files to Amazon S3. Set up a lifecycle policy to move the rarely-used files to S3 Glacier

Explanation
Amazon EFS offers an Infrequent Access (IA) storage class, which can be managed via EFS lifecycle policies. Frequently accessed files remain in the Standard storage class, while infrequently accessed files are automatically moved to the IA class, significantly reducing storage costs with minimal effort and no application changes.
