A company is planning a disaster recovery testing strategy. They want to validate both RTO and RPO without impacting production. Which THREE approaches should they consider? (Choose THREE.)
Trap 1: Run load tests against production systems
Load testing targets performance, not recovery; it may also impact production.
Trap 2: Use chaos engineering to inject failures in production
Injecting failures in production clearly impacts operations and violates the requirement to avoid production impact.
- A
Perform regular backup restoration tests
Backup restoration tests directly verify that backups can be restored within RTO and RPO limits without affecting production.
- B
Conduct scheduled DR drills in a separate environment
DR drills in an isolated environment test failover procedures without risking production systems.
- C
Run load tests against production systems
Why wrong: Load testing targets performance, not recovery; it may also impact production.
- D
Use chaos engineering to inject failures in production
Why wrong: Injecting failures in production clearly impacts operations and violates the requirement to avoid production impact.
- E
Enable continuous monitoring of production metrics
Continuous monitoring of production metrics, such as recovery times from backups or replication lag, provides passive validation of RTO/RPO without disrupting services.
