Which risk control technique reduces the potential impact of a single event by ensuring redundancy across independent resources?

• A. Diversification
• B. Separation
• C. Duplication
• D. Protection

Answer: (C)

Redundancy, or duplication of resources, is a risk control technique that lowers the potential impact of a single event by providing independent backups that can take over if one component fails. The key idea is independence: having multiple copies or alternative pathways means a single disruption won’t knock out the entire system because another resource can maintain operations. For example, a data center might have mirrored servers in separate locations and dual power feeds from different utility sources, so if one path is disrupted, the others keep systems running. This contrasts with diversification (spreading risk across different exposures), separation (physically or functionally separating components to reduce the chance of a single event affecting all), and protection (putting barriers in place to prevent losses but not necessarily guaranteeing a substitute resource). The duplication approach directly creates a substitute resource that preserves function when an event impacts one part.
