SY0-701 Question 237
Single answerTesting: Tabletop exercises , Fail over , Simulation , Parallel processingA healthcare organization is preparing to test its disaster recovery capabilities for an electronic medical records (EMR) platform. Management wants the most realistic validation possible that the secondary site can take over processing if the primary data center fails, but they also want to avoid disrupting patient care or risking production data. Which testing approach best meets this requirement?
- A
Conduct a tabletop exercise with infrastructure, security, and clinical operations leaders to walk through the recovery steps
- B
Run a simulation in which the team practices the disaster recovery procedures without moving live production workloads
- C
Perform a failover test by shutting down the primary EMR environment and forcing all users to the secondary site during business hours
- D
Use parallel processing by running the secondary EMR environment alongside production and comparing results before cutover
Show answer and explanation
Correct answer: D
Explanation
The best answer is parallel processing. In disaster recovery and business continuity testing, testing methods vary in realism and operational risk. Tabletop exercises are low-risk, discussion-based reviews of roles and procedures. Simulations are more hands-on and can mimic an incident, but they still do not fully validate live processing capability. Failover testing provides strong assurance because production services actually shift to the alternate environment, but it carries higher business risk. Parallel processing is often the best balance when an organization needs realistic validation without disrupting live operations: both environments operate concurrently, and results can be compared before any real cutover. This aligns with common business continuity and disaster recovery practices described in industry guidance such as NIST contingency planning recommendations, which distinguish between discussion-based and operational testing methods and emphasize selecting a test type based on realism, safety, and business impact.
- A. Incorrect.
This is incorrect because a tabletop exercise is discussion-based and validates roles, communication paths, and decision-making, but it does not provide technical proof that the secondary site can actually process workloads. It is useful for reviewing plans and identifying procedural gaps, yet it is less realistic than an operational test of systems.
- B. Incorrect.
This is incorrect because a simulation is more realistic than a tabletop exercise and can test procedures in a controlled manner, but it still does not provide the same level of assurance as operating the recovery environment in parallel with production. The scenario specifically asks for the most realistic validation possible while avoiding disruption to patient care and production data.
- C. Incorrect.
This is incorrect because a live failover test would provide strong validation, but it introduces operational risk by moving actual users and workloads to the secondary site during business hours. In a healthcare setting, this could disrupt patient care, making it inconsistent with the requirement to avoid risking production operations.
- D. Correct.
This is correct because parallel processing allows the organization to run the secondary environment at the same time as the primary environment and compare outputs without immediately cutting over production users. This provides a high-confidence test of recovery capability and system readiness while minimizing business disruption. It is commonly used when organizations need strong assurance that systems at the alternate site will function correctly before relying on them in a real outage.
