If a customer has an RPO of 4 hours and an RTO of 1 hour, which DR methods would you recommend? (Choose 2)

The customer's requirements specify a Recovery Point Objective (RPO) of 4 hours and a Recovery Time Objective (RTO) of 1 hour. The RPO indicates that the customer can tolerate losing up to 4 hours of data, while the RTO signifies the maximum acceptable downtime of 1 hour.

Given these parameters, two recommended disaster recovery (DR) methods would be to have a cluster ready in another region and to replicate data in near real-time.

Having a cluster ready in another region ensures that, in the event of a disaster, the infrastructure can be brought online quickly, aiding in meeting the stringent RTO of 1 hour. This method ensures that the systems are pre-provisioned and prepared for failover, which allows for rapid recovery.

Replicating data in near real-time provides the necessary data protection within the acceptable RPO. By doing so, the organization can minimize the amount of data loss during a disruption, ensuring that they are within the 4-hour tolerance for data loss. This method also enhances the potential for business continuity by keeping the data current and readily available for recovery.

Using on-premise backups, while reliable, may not meet the RTO and RPO requirements effectively. Backups are typically
