Show answer & explanation
Correct answer: D
Answer: A bridge operates at the Data Link Layer (Layer 2) of the OSI model. Why: Bridges forward and filter link-layer frames using MAC addresses; they do not make routing decisions based on IP addresses or examine transport-layer ports. Learns MAC addresses and builds a forwarding (MAC) table.
