Explanation

Parallel testing activates backup systems alongside live production systems simultaneously, allowing organizations to validate recovery capabilities against both internal disruptions (system failures, process breakdowns) and external threats (natural disasters, cyberattacks) while keeping primary operations fully intact and uninterrupted.

Why the distractors are wrong:

• A. Walkthrough - A paper-based tabletop exercise where team members verbally review procedures; no systems are activated at all, so it doesn't truly test resilience under realistic conditions.
• B. Simulation - Mimics a disaster scenario with role-playing, but does not bring actual backup systems online or validate technical recovery processes.
• D. White box - A software testing methodology where testers have full knowledge of system internals; it is not a recognized business continuity test type in this context.

Memory tip: Think of "parallel" like parallel parking - both your car (backup system) and the adjacent cars (live operations) are present at the same time, side by side, with neither one disrupted. If the test were a full interruption test, you'd be towing the live car away entirely - that's when operations get endangered.
