A company needs to migrate an on-premises SFTP site to AWS. The SFTP site currently runs on a Linux VM. Uploaded files are made available to downstream applications through an NFS share. As part of the migration to AWS, a solutions architect must implement high availability. The solution must provide external vendors with a set of static public IP addresses that the vendors can allow. The company has set up an AWS Direct Connect connection between its on-premises data center and its VPC. Which solution will meet these requirements with the LEAST operational overhead?

A. Create an AWS Transfer Family server. Configure an internet-facing VPC endpoint for the Transfer Family server. Specify an Elastic IP address for each subnet. Configure the Transfer Family server to place files into an Amazon Elastic File System (Amazon EFS) file system that is deployed across multiple Availability Zones. Modify the configuration on the downstream applications that access the existing NFS share to mount the EFS endpoint instead.
B. Create an AWS Transfer Family server. Configure a publicly accessible endpoint for the Transfer Family server. Configure the Transfer Family server to place files into an Amazon Elastic File System (Amazon EFS) file system that is deployed across multiple Availability Zones. Modify the configuration on the downstream applications that access the existing NFS share to mount the EFS endpoint instead.
C. Use AWS Application Migration Service to migrate the existing Linux VM to an Amazon EC2 instance. Assign an Elastic IP address to the EC2 instance. Mount an Amazon Elastic File System (Amazon EFS) file system to the EC2 instance. Configure the SFTP server to place files in the EFS file system. Modify the configuration on the downstream applications that access the existing NFS share to mount the EFS endpoint instead.
D. Use AWS Application Migration Service to migrate the existing Linux VM to an AWS Transfer Family server. Configure a publicly accessible endpoint for the Transfer Family server. Configure the Transfer Family server to place files into an Amazon FSx for Lustre file system that is deployed across multiple Availability Zones. Modify the configuration on the downstream applications that access the existing NFS share to mount the FSx for Lustre endpoint instead.
