A company wants to use Amazon FSx for Windows File Server for its Amazon EC2 instances that have an SMB file share mounted as a volume in the us-east-1 Region. The company has a recovery point objective (RPO) of 5 minutes for planned system maintenance or unplanned service disruptions. The company needs to replicate the file system to the us-west-2 Region. The replicated data must not be deleted by any user for 5 years.
Which solution will meet these requirements?

A
Create an FSx for Windows File Server file system in us-east-1 that has a Single-AZ 2 deployment type. Use AWS Backup to create a daily backup plan that includes a backup rule that copies the backup to us-west-2. Configure AWS Backup Vault Lock in compliance mode for a target vault in us-west-2. Configure a minimum duration of 5 years.
B
Create an FSx for Windows File Server file system in us-east-1 that has a Multi-AZ deployment type. Use AWS Backup to create a daily backup plan that includes a backup rule that copies the backup to us-west-2. Configure AWS Backup Vault Lock in governance mode for a target vault in us-west-2. Configure a minimum duration of 5 years.
C
Create an FSx for Windows File Server file system in us-east-1 that has a Multi-AZ deployment type. Use AWS Backup to create a daily backup plan that includes a backup rule that copies the backup to us-west-2. Configure AWS Backup Vault Lock in compliance mode for a target vault in us-west-2. Configure a minimum duration of 5 years.
D
Create an FSx for Windows File Server file system in us-east-1 that has a Single-AZ 2 deployment type. Use AWS Backup to create a daily backup plan that includes a backup rule that copies the backup to us-west-2. Configure AWS Backup Vault Lock in governance mode for a target vault in us-west-2. Configure a minimum duration of 5 years.

Explanation
Key Requirements Analysis:
- RPO of 5 minutes - This requires Multi-AZ deployment for FSx for Windows File Server, as Single-AZ 2 deployment doesn't provide the required RPO.
- Replication to us-west-2 Region - Achieved through AWS Backup cross-region copy.
- Data retention for 5 years with no deletion - Requires AWS Backup Vault Lock in compliance mode (not governance mode).
Why Option C is Correct:
- Multi-AZ deployment: FSx for Windows File Server Multi-AZ deployment provides synchronous replication across Availability Zones with an RPO of 5 minutes, meeting the requirement for planned/unplanned disruptions.
- AWS Backup with cross-region copy: Creates backups in us-west-2 region.
- AWS Backup Vault Lock in compliance mode: Ensures backups cannot be deleted by any user (including root account) for the specified retention period (5 years). Governance mode allows deletion by privileged users with specific IAM permissions.
Why Other Options are Incorrect:
- Options A & D: Use Single-AZ 2 deployment, which doesn't meet the 5-minute RPO requirement.
- Options B & D: Use governance mode instead of compliance mode, which doesn't guarantee that data won't be deleted for 5 years.
Additional Context:
- FSx for Windows File Server Multi-AZ provides automatic failover with minimal disruption.
- AWS Backup Vault Lock compliance mode provides WORM (Write Once Read Many) protection that cannot be bypassed.
- Daily backup plan with cross-region copy ensures disaster recovery capabilities.
