A transit authority wants to validate its DR plan without cutting over live rider apps yet. Leadership also wants a later exercise that runs recovery systems in parallel with production. Which testing progression best fits?
Select an answer to reveal the explanation.
Short Explanation
Crawl, then walk, then jog. Talk through the plan (tabletop/walkthrough), practice under simulation or parallel load, and only later risk a full cutover. Jumping straight to yanking production is how you strand riders.
Full Explanation
DRP testing types range from discussion-based tabletops and walkthroughs, through simulations and parallel tests that exercise recovery environments beside production, to full interruption tests that actually fail over live services. Organizations typically escalate intensity as confidence grows and always communicate status to stakeholders. Parallel testing validates recovery capability with less operational risk than immediate full interruption. Skipping milder exercises removes low-cost discovery of role and procedure gaps.
