A production environment and its disaster recovery (DR) environment were deployed in the same AWS Region. Applications run on EC2 instances and use an FSx for NetApp ONTAP volume for storage; no application data is on the EC2 instances. AMIs were copied to a DR Region and CloudFormation templates were parameterized by Region. The storage RPO must be 10 minutes in the DR Region. What solution satisfies this requirement?

The correct solution is to deploy an FSx for ONTAP instance in the DR Region and configure NetApp SnapMirror replication. FSx for NetApp ONTAP supports SnapMirror, a native NetApp technology for efficient, incremental replication of volumes. Setting a 5-minute replication schedule ensures the 10-minute RPO is met, as data will be replicated frequently enough to recover within the specified window. Incorrect options: S3 Cross-Region Replication with a Lambda to copy from FSx ONTAP is inefficient and complex for block storage, and likely won't meet the RPO reliably due to the overhead of copying data to S3. AWS Backup can back up FSx for ONTAP, but the question states EC2 instances are assigned to the backup plan, not the FSx volume. Even if the FSx volume were backed up, AWS Backup's minimum RPO for FSx is typically 1 hour, not 10 minutes. Lambda to snapshot instance store volumes is irrelevant because the question states "no application data is on the EC2 instances" and the primary storage is FSx for ONTAP.
