Final answer:
A Disaster Recovery Plan outlines steps a business will take following a disaster to resume normal operations. It is part of a Business Continuity Plan which ensures the continuation of critical business functions.
Step-by-step explanation:
The type of plan that outlines the procedures to follow when a disaster interrupts the normal operations of a business is known as a Disaster Recovery Plan (DRP). A DRP is part of a broader Business Continuity Plan (BCP), which ensures that critical business functions continue during and after a disaster. The vulnerability assessment is a process that identifies, quantifies, and prioritizes the vulnerabilities in a system, while a business impact assessment evaluates the potential effects of an interruption to critical business operations as a result of a disaster, accident, or emergency.
Referring to Figure 20.1, choosing between Plan A and Plan B can be thought of in terms of risk management, which is central to both DRP and BCP.
