Q

By default routers pass Broadcast traffic from one network to another network.

A. True
B. False

A

B. False

Explanation: Routers do not pass Broadcast traffic by default. If routers did pass normal Broadcast traffic then that Broadcast traffic would have the potential to spread around the entire global internet without restriction. We can see how this would be a problem! Broadcast traffic is intended to stay within a local network which is also know as a Broadcast Domain.
