Which term best describes a plan to restore IT infrastructure after a disaster?

• A. Business Continuity Plan
• B. Incident Response Plan
• C. Disaster Recovery Plan
• D. Service Continuity Plan

Answer: (C)

Restoring IT infrastructure after a disruptive event is addressed most precisely by a Disaster Recovery Plan. This plan focuses on recovering the IT environment—servers, networks, storage, databases, and applications—so that critical systems and data come back online within defined timeframes. It includes recovery objectives like RTO (how quickly to recover) and RPO (how much data loss is acceptable), backup and restoration procedures, failover to alternate sites, and roles and communications for the recovery effort.

A business continuity plan covers overall operations and how the business keeps functioning, not just IT recovery. An incident response plan is about identifying and responding to cybersecurity incidents, not the full IT restoration process. A service continuity plan is less standard and refers more generally to maintaining service delivery without specifying the IT restoration steps as clearly as a DRP.
