Advanced Networking Administrator Test Prep

Answer: C - Routers initiate broadcasts, but do not forward them.

Key Takeaway: A router is a device used to break up broadcast domains. A broadcast domain is a logical part of a network where any network device can transmit data directly to another device without going through a routing device. A router blocks a layer-2 broadcast, like an ARP request, which is sent by a machine on the network to all devices on the network. The only time when a router will originate a broadcast is when a router is sending update information using routing protocols like RIP.
