Which of the following plans describes the process by which an organization manages a major outage?

A contingency plan is a general-purpose plan for unexpected scenarios and is not specifically focused on managing operational continuity during a major outage.

Site-to-site backup is a data replication or backup strategy, not a planning framework for managing an organization's response to an outage.

A disaster recovery plan focuses specifically on restoring IT systems and data after a disaster, which is a subset of business continuity rather than the complete outage management process.

Business continuity encompasses the full organizational strategy for sustaining critical operations throughout a major outage, covering people, processes, and technology together. It is broader than disaster recovery and addresses how the business continues to function during the disruption, not only how IT systems are restored afterward.
