Reveal correct answer
Correct answer: C
Explanation
Correct Answer:
C is correct. A bridge uses physical (MAC) addresses when making decisions on where to send traffic. Bridges can perform simple forwarding functionality or more complex filtering, but each function is based on the MAC address, which lies within the data link layer of the OSI model.
Incorrect Answers:
A is incorrect. Bridges work at the data link layer, not the physical layer.
B is incorrect. Bridges work at the data link layer, not the application layer.
D is incorrect. Bridges work at the data link layer, not the network layer.
