Which disaster recovery plan is very expensive and disrupts normal business operations?

Full Interruption Testing involves shutting down primary systems to test recovery processes, making it expensive (due to downtime costs) and disruptive to normal operations.

Option B (Simulation Testing):Mimics a disaster without stopping operations.

Option C (Parallel Testing):Runs recovery systems alongside primary ones, non-disruptive.

Option D (Checklist Testing):A review process, no operational impact.

“Full Interruption Testing, while thorough, incurs high costs and disrupts business by halting primary systems to validate recovery” (Module: Testing Disaster Recovery Plans, Section: Test Types).
