PAS-C01 Migration Practice Question
A company wants to migrate its SAP HANA database to AWS using SAP HANA Database Backup and Recovery. The backup files are stored on an NFS share on-premises. The company wants to restore these backups directly to an Amazon EC2 instance running SAP HANA. Which AWS storage service should they use to make the NFS backup files accessible to the EC2 instance?

Correct answer & explanation
✓
Amazon EFS
Amazon EFS provides a scalable NFS file system that can be mounted on EC2 instances. The backup files can be copied from on-premises NFS to EFS using AWS DataSync or other methods, and then used for restore. Options A, B, D are incorrect because S3 is object storage (not NFS), FSx for Windows File Server is SMB, and EBS is block storage not NFS.
