Question

A financial services firm must validate its disaster recovery plan for a core transaction-processing system. The CISO wants the highest-confidence test that proves the recovery site can handle real production workloads, but the business absolutely cannot tolerate any downtime or risk to the live production environment during the exercise. Which DR test type best satisfies these competing requirements?

Accepted Answer

Parallel test, where recovery systems are brought online and process real workloads alongside production without shutting production down

Answer

Full-interruption test, where production is shut down and operations fail over entirely to the recovery site

Answer

Structured walkthrough, where recovery team members review the plan step-by-step in a conference room

Answer

Simulation test, where the team responds to a scripted scenario without activating any recovery systems
