A company is migrating a legacy Windows file server that holds sensitive, irreplaceable data to Amazon FSx for Windows File Server. The data must be copied to another AWS Region for disaster recovery, and compliance requires that data never traverse the public internet. The company prefers managed AWS services where possible. Which design meets these requirements?

This solution is correct because it uses VPC peering for private network connectivity between regions, ensuring data never traverses the public internet, as required. AWS DataSync is an excellent managed service for migrating and synchronizing file data, and configuring it with interface VPC endpoints (AWS PrivateLink) guarantees that the data transfer remains entirely within the AWS network, meeting the compliance requirement. Using FSx for Windows File Server in the DR Region provides a native, managed file server solution for disaster recovery. The other options are incorrect: FSx File Gateway is designed for on-premises integration with FSx, not for cross-region FSx replication. AWS Site-to-Site VPN is a valid connectivity option, but AWS DataSync can communicate more efficiently and securely over VPC peering with PrivateLink for inter-region AWS service-to-service communication. AWS Transfer Family is for transferring files to and from S3, not directly between FSx file systems. While Transit Gateway can provide inter-region connectivity, DataSync with PrivateLink is a more direct and managed solution for file synchronization between FSx instances.
