Which approach best supports resilience against link disruption in Link 16 by maintaining alternate routing paths?

• A. Relying on a single, hardened backbone with no backups.
• B. Maintaining multiple paths and alternative routes to the network.
• C. Disabling automatic routing to keep control.
• D. Increasing transmission power to overcome losses.

Answer: (B)

Redundancy through multiple routing paths is the key to resilience. By keeping several paths and alternate routes to the Link 16 network, traffic can be rerouted automatically if any single link or node deteriorates or fails. This means the network can maintain communication even in contested or degraded environments, preserving mission data flow without waiting for a manual fix. Relying on a single backbone creates a weak point where disruption stops traffic entirely, and disabling automatic routing removes the system’s ability to adapt to changing conditions. While increasing power might help a marginally, it doesn’t provide alternate paths or automatic rerouting, and it can introduce more interference. So the approach that maintains multiple paths best supports resilience against link disruption.
