Domain overview
This domain covers how organizations keep operating and recover when disruption hits. For CC, it is tested through scenario questions on business impact analysis, recovery objectives, plan components, and incident response steps. You must distinguish continuity from recovery, understand RTO versus RPO, and know the sequence of detecting, containing, eradicating, and recovering from incidents.
Exam objectives
Business impact analysis identifying critical business functions and their dependencies
Recovery time objective versus recovery point objective for critical systems
Incident response lifecycle phases: preparation, detection, containment, eradication, recovery, lessons learned
Crisis communications components including notification, escalation, and stakeholder messaging
Confusing RTO with RPO: RTO is acceptable downtime, RPO is acceptable data loss measured in time.
Assuming disaster recovery and business continuity are the same; DR restores IT, BCP keeps the whole business running.
Skipping business impact analysis and jumping straight to plan writing, so critical functions and dependencies are missed.
