Answer: Implement an AWS Storage Gateway Volume Gateway cached volume with a 10 TB local cache, iSCSI mount to the file server, file transfer, and scheduled snapshots. For disaster recovery, snapshot restoration to an Amazon EBS volume attached to an EC2 instance.
The correct answer is C: 'Implement an AWS Storage Gateway Volume Gateway cached volume with a 10 TB local cache, iSCSI mount to the file server, file transfer, and scheduled snapshots. For disaster recovery, snapshot restoration to an Amazon EBS volume attached to an EC2 instance.' This solution ensures minimal changes to the existing infrastructure while providing immediate access to all file types with low latency. The Volume Gateway cached volume provides a cost-effective storage solution since only the frequently accessed data is stored locally. The cloud retains backups, making disaster recovery efficient by restoring snapshots to Amazon EBS and attaching it to an EC2 instance.

A company seeks a disaster recovery solution for its primary on-premises file storage, mounted via iSCSI, containing hundreds of TB of data. The solution must ensure uninterrupted, latency-free access for end users and minimal changes to existing infrastructure.
A
Deploy an Amazon S3 File Gateway VM on-premises with a 10 TB local cache, adjust applications for NFS access, and use EC2 for S3 bucket mounting in a disaster scenario.
B
Utilize an AWS Storage Gateway tape gateway for data backup to a virtual tape library, with nightly backups post-initial backup, and EC2 for data restoration to Amazon EBS in case of disaster.
C
Implement an AWS Storage Gateway Volume Gateway cached volume with a 10 TB local cache, iSCSI mount to the file server, file transfer, and scheduled snapshots. For disaster recovery, snapshot restoration to an Amazon EBS volume attached to an EC2 instance.
D
Set up an AWS Storage Gateway Volume Gateway stored volume matching the existing storage size, iSCSI mount and file transfer to it, and enable snapshot scheduling. In a disaster, restore from a snapshot to an Amazon EBS volume for EC2 attachment.
