Describe the role of "redundant pathways" in SEW resilience.

• A. Provide alternative links or paths to maintain critical communications if a primary link is jammed or degraded
• B. Increase dependency on a single primary link
• C. Reduce available bandwidth
• D. Remove need for crosslinks

Answer: (D)

Redundant pathways are about keeping critical communications alive even when the main route is compromised. In SEW resilience, the goal is to have multiple independent routes so that if one path is jammed, degraded, or damaged, traffic can automatically switch to a backup path without interrupting the flow. This eliminates a single point of failure and enables rapid recovery, ensuring command and control and data stay available under interference or attack. Crosslinks between network nodes are how these extra routes are created, providing alternative channels for the same information. Choices that push toward a single path, reduce bandwidth, or remove crosslinks don’t support resilience because they leave the system vulnerable to disruption and lack fallback options.
