Rely solely on manual documentation stored on local laptops for failover steps.

Question 10

Which THREE factors should an architect evaluate when determining Recovery Point Objective (RPO) and Recovery Time Objective (RTO) for an OCI database disaster recovery solution? (Choose three.)

Accepted Answer

Level of automation configured for failover (e.g., Fast-Start Failover vs. manual scripts). RPO and RTO are driven by business tolerance for data loss, network throughput/latency constraints for replication, and the degree of automation (like FSFO or FSDR) applied to failover procedures.
