A city municipality lost its primary data center when a tornado hit the facility. Which of the following should the city staff use immediately after the disaster to handle essential public services?

The correct answer is DRP (Disaster Recovery Plan). A DRP outlines the procedures for restoring critical IT systems and operations after a catastrophic event like a tornado. Its immediate implementation ensures the continuity of essential public services by bringing systems back online. BCP (Business Continuity Plan) is incorrect because while it encompasses DRP, a BCP is a broader strategy for maintaining business functions during and after a disruption, not the immediate technical recovery plan. The question specifically asks what to use immediately after the disaster to handle essential public services, pointing to the technical recovery. A Communication plan is incorrect because it focuses on how to disseminate information during a crisis, not on the technical recovery of services. While crucial, it's a component of a broader response, not the recovery plan itself. IRP (Incident Response Plan) is incorrect because it deals with responding to security incidents (e.g., cyberattacks, data breaches), not natural disasters that destroy physical infrastructure.
