Which risk control technique uses back-ups for critical systems to reduce loss severity?

Which risk control technique uses back-ups for critical systems to reduce loss severity?

• A. Avoidance
• B. Mitigation
• C. Frequency
• D. Duplication

Answer: (D)

Redundancy through duplication is about having duplicate systems and up-to-date backups ready to take over if the primary ones fail. This approach keeps operations running and minimizes downtime and data loss, which lowers the overall impact when a disruption occurs. Back-ups and redundant infrastructure provide a quick, reliable path to continuity, so the severity of losses is reduced. The other options don’t specifically focus on creating duplicates or ready-to-switch systems: avoidance would skip the activity entirely, mitigation reduces impact without necessarily duplicating resources, and frequency isn’t about implementing protective measures.
