Answer: Implement an active-active architecture that provides real-time data replication across two Regions. Use Amazon Route 53 health checks and a weighted routing policy.
To achieve an RTO of less than 10 minutes and an RPO of zero, an active-active architecture with real-time data replication is necessary. This setup ensures that both regions are actively serving traffic and data is immediately replicated, eliminating data loss and minimizing downtime.

Question #81
A global company runs a critical primary workload in the us-east-1 Region. The company wants to ensure business continuity with minimal downtime in case of a workload failure. The company wants to replicate the workload to a second AWS Region.
A CloudOps engineer needs a solution that achieves a recovery time objective (RTO) of less than 10 minutes and a zero recovery point objective (RPO) to meet service level agreements.
Which solution will meet these requirements?
A
Implement a pilot light architecture that provides real-time data replication in the second Region. Configure Amazon Route 53 health checks and automated DNS failover.
B
Implement a warm standby architecture that provides regular data replication in a second Region. Configure Amazon Route 53 health checks and automated DNS failover.
C
Implement an active-active architecture that provides real-time data replication across two Regions. Use Amazon Route 53 health checks and a weighted routing policy.
D
Implement a custom script to generate a regular backup of the data and store it in an S3 bucket that is in a second Region. Use the backup to launch the application in the second Region in the event of a workload failure.
