Broadcast Forwarding Behavior

What this IP broadcast networking question tests

This is an easy networking fundamentals question that checks whether a candidate understands the routing principles behind broadcast traffic in IP networks. It probes core knowledge of how routers distinguish between unicast, multicast, and broadcast frames, and the policy decisions they enforce.

The question rewards clear understanding of address scope, network boundaries, and why certain traffic patterns are or are not forwarded across router interfaces. It's a foundation concept for anyone working on infrastructure, trading systems, or any application that depends on reliable network behaviour. Candidates should be able to explain the reasoning behind routing decisions, not just memorize rules.
