ISC2 CC Business Continuity, DR & Incident Response Practice Question
Which THREE are commonly defined in a disaster recovery plan? (Select exactly 3.)
⚠ Common exam trap
ISC2 often tests the distinction between the DR plan components (RPO, RTO, BIA) and risk management calculations (ALE, cost-benefit analysis), trapping candidates who confuse the outputs of a BIA with separate financial analysis tools.

Correct answer & explanation
✓
Recovery point objective
Recovery point objective (RPO) is a core metric defined in a disaster recovery plan because it specifies the maximum acceptable amount of data loss measured in time. For example, an RPO of 1 hour means backups must be taken at least every hour to ensure no more than 60 minutes of data is lost. This directly drives backup frequency and replication technology choices, such as synchronous vs. asynchronous replication.
