Answer is C https://aws.amazon.com/efs/ Amazon Elastic File System (Amazon EFS) provides a simple, serverless, set-and-forget, elastic file system that lets you share file data without provisioning or managing storage. It can be used with AWS Cloud services and on-premises resources, and is built to scale on demand to petabytes without disrupting applications. With Amazon EFS, you can grow and shrink your file systems automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.

- C - Application communicates to file system via NFS --> only EFS supports this A. AWS DataSync - Wrong. For data migration, NOT storage B. Amazon Elastic Block Store (Amazon EBS) - Wrong. Does not support NFS C. Amazon Elastic File System (Amazon EFS) - Correct. Supports NFS D. Amazon EMR File System (Amazon EMRFS) - Wrong. Does not support NFS. EMRFS is an implementation of HDFS - https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-fs.html

just to ass to comments here,EBS is incorrect because it does not use NFS. Exact protocol is unclear but its iscsi/SAN combination. EFS uses NFS protocol. Intial read of question gives feels of storage gw though!

Never mind. The question is asking about a solution for after migration which in that case answer C is correct.

the question asks for "... recommend for use after the migration?" Not asking how to migrate.
