Question 5
Domain 4: Security Operations, Monitoring, and Incident ResponseAn organization requires a Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 1 hour for a critical cloud-based application. Which disaster recovery approach is MOST appropriate?
Correct answer: C
Explanation
Warm standby with continuous replication fits a 4-hour RTO and 1-hour RPO because the standby environment is already running and can be brought online quickly, while continuous replication keeps data loss within about an hour. This approach balances speed and data protection better than cold or pilot-light recovery for a critical cloud application.
Why each option is right or wrong
A. Backup and restore with daily snapshots
B. Pilot light with automated failover
C. Warm standby with continuous replication
A warm standby is the appropriate DR tier when the application must be restored within a few hours, because the secondary environment is already provisioned and only needs to be scaled or activated, which aligns with a 4-hour RTO. Continuous replication is the feature that satisfies the 1-hour RPO by keeping the data copy near-current, limiting potential data loss to no more than about 60 minutes; cold site or pilot-light options would typically exceed both targets.
D. Multi-site active-active configuration
