What does disaster recovery (DR) focus on?

• A. Keeping the system operational when a component fails
• B. Restoring a system to a previous acceptable state after a disaster
• C. Scaling horizontally to multiple runtimes
• D. Balancing load across nodes

Answer: (B)

Disaster recovery focuses on restoring a system to a known, acceptable state after a disruptive event. It centers on bringing back data and services to a recoverable point within agreed timelines and data loss limits, using backups, replicated environments, and tested recovery procedures. This makes it possible to resume operations after a disaster. This differs from keeping the system running during an outage (that’s about high availability and business continuity) and from scaling or balancing traffic (which are about capacity and performance, not recovery after a disaster).
