GATE | GATE-CS-2004 | Question 16

Which of the following is NOT true with respect to a transparent bridge and a router?
(A) Both bridge and router selectively forward data packets
(B) A bridge uses IP addresses while a router uses MAC addresses
(C) A bridge builds up its routing table by inspect­ing incoming packets
(D) A router can connect between a LAN and a WAN


Answer: (B)

Explanation: Network Devices
Bridges are used to connect two or more networks and create a bigger network. A bridge works up upto the second layer only, i.e. it only implements the Physical and Data Link layers. Therefore it does not use IP addresses for its routing.
Therefore option (B) is correct.
