ISC2 CC Business Continuity, DR & Incident Response Practice Question
Which TWO are appropriate methods to test a disaster recovery plan?
⚠ Common exam trap
ISC2 often tests the distinction between DR testing methods (parallel, simulation, walkthrough) and software development testing types (unit, regression, acceptance), leading candidates to incorrectly select development tests as valid DR validation techniques.

Correct answer & explanation
✓
Parallel test
A parallel test is appropriate because it runs the DR site in parallel with the production environment, allowing validation of failover processes and data replication without impacting live operations. This method verifies that the backup systems can handle real workloads and that synchronization mechanisms (e.g., asynchronous replication or log shipping) are functioning correctly. It provides a high-confidence check of the DR plan's effectiveness while maintaining business continuity.
