How do you distinguish between a bridge and a router?
Correct Answer: D
Explanation/Reference: Explanation: Bridges and routers both connect networks. While bridges works only up to the data link layer, routers work at the network layer. Incorrect Answers: A: Both bridges and routers connect multiple networks. A router examines each packet to determine which network to forward it, but bridges can also examine packets by using filters to determine if the data should be forwarded or not. B: Bridge and router are not synonyms as they work at different network layers. C: A bridge is not one type of router. A bridge cannot connect a LAN to the Internet as it only working at the data link layer, and you need to work at the network layer to connect a LAN to the Internet.
