Which risk control technique involves creating backups or duplicates of critical systems?

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

Answer: (D)

Duplication is a risk control approach that builds resilience by creating backups or duplicates of critical systems. By having a copy ready to take over, operations can continue with little downtime if the primary system fails, reducing the impact of outages and avoiding a single point of failure. This often involves mirrored data, redundant hardware, or failover setups (hot, warm, or cold standby), and can support recovery objectives like RTO and RPO. The other options describe different concepts: hazard is the danger itself, frequency is how often events occur, and avoidance is choosing not to engage in the activity to prevent risk.
