Answer: On-premises, deploy an S3 File Gateway with a public endpoint, create an S3 bucket and NFS share, and migrate data from the current NFS to the new S3-backed share.
The correct answer is C. Deploying an S3 File Gateway on premises and creating a new NFS file share on the gateway allows seamless migration of data from the existing NFS share to Amazon S3 with minimal bandwidth usage. This solution is efficient for large-scale data migration because it leverages local network transfer initially and then synchronizes with S3. The other options either involve more complex setup (D) or cannot efficiently handle such large volumes of data (A). Option B is also a feasible solution but relies on physical transport, which may not be as immediate as the S3 File Gateway method.

A company with 70 TB of NFS-stored video files, ranging from 1 MB to 500 GB, seeks a rapid, bandwidth-efficient migration to Amazon S3. What is the optimal solution?
A
Create an S3 bucket, assign an IAM role for S3 write access, and use AWS CLI for local file transfer to S3.
B
Initiate an AWS Snowball Edge job, transfer data using the device provided, and return it for AWS to upload to S3.
C
On-premises, deploy an S3 File Gateway with a public endpoint, create an S3 bucket and NFS share, and migrate data from the current NFS to the new S3-backed share.
D
Establish AWS Direct Connect, deploy an S3 File Gateway with a public VIF, create an S3 bucket and NFS share, and migrate data to the S3 File Gateway.
