Which testing method should a financial institution use to evaluate its disaster recovery plan in a production-like environment?

• A. Full System Test
• B. Parallel Testing
• C. Tabletop Exercise
• D. Dry Run

Answer: (B)

The best choice for evaluating a disaster recovery plan in a production-like environment is parallel testing. This method allows the financial institution to run the recovery procedures alongside the normal operations without interrupting the production systems. During parallel testing, the backup systems are activated to ensure that they can handle the workload and meet the necessary performance and functional standards.

This approach provides a realistic assessment of the disaster recovery process, allowing organizations to identify potential issues and validate the effectiveness of the recovery protocols. It is particularly important for industries like finance where data integrity and system availability are critical.

In contrast, full system tests may disrupt ongoing operations, while tabletop exercises focus on discussion rather than actual system performance, and dry runs may not effectively replicate real-world conditions, making them less suitable for comprehensive evaluation in a production-like setting. Parallel testing strikes the right balance by allowing for testing in a manner that closely resembles actual operational conditions, thus offering an accurate reflection of preparedness.
