Disaster Recovery refers to

• A. The ability to provide IT services following an interruption, often at an alternate location.
• B. The ongoing operation of IT services during a normal business day.
• C. The design of a secure network topology.
• D. The plan for long-term business strategy.

Answer: (A)

Disaster Recovery centers on restoring IT services after a disruption, including the ability to resume operations, often by switching to an alternate location such as a hot, warm, or cold site. It focuses on getting systems and data back online quickly after an incident, guided by recovery objectives like RTO (recovery time) and RPO (recovery point). This emphasis on bringing IT back up and running after an interruption, sometimes at a different site, is what sets DR apart.

Ongoing operation during a normal business day describes day-to-day service continuity, not recovery after a disruption. Designing a secure network topology is about protecting the network, not recovering services after an outage. Planning for long-term business strategy relates to strategic direction, not IT service restoration.
