Which statement best describes resilience in a cyber system?

• A. Redundant networks with automatic failover and rapid recovery processes.
• B. Single-path critical infrastructure without backups.
• C. No monitoring to reduce overhead.
• D. Manual recovery without automation.

Answer: (B)

Resilience in a cyber system means it can continue operating and recover quickly when disruptions occur, by anticipating failures, maintaining essential functions, and restoring services fast. Redundant networks with automatic failover and rapid recovery processes embody this idea because redundancy provides alternative paths so a single failure doesn’t halt operations, automatic failover switches traffic without waiting for human intervention, and rapid recovery processes bring services back online quickly. This combination keeps critical functions available and minimizes downtime, which is the essence of resilience. A single-path infrastructure without backups creates a clear point of failure and cannot sustain operations if a component fails. No monitoring makes problems harder to detect and respond to promptly, increasing downtime and impact. Manual recovery without automation is slower and more error-prone, undermining the speed and consistency resilience requires.
