Correct answer: A
Answer: A bridge has access to physical (MAC) addresses in the same network.
Explanation:
Bridges operate at the data link layer (Layer 2). They learn and use hardware (MAC) addresses — often called physical addresses — to decide how to forward Ethernet frames. Because they forward at Layer 2, bridges only forward frames within the same broadcast domain or LAN segment and do not use IP (network layer) addresses to route between networks.
Operates at: Data link layer (Layer 2).
Address used: Physical (MAC) address.
Scope: Only devices in the same LAN/broadcast domain.
Contrast: Routers use network (IP) addresses to forward between different networks.
Example: When a frame arrives at a bridge, the bridge checks the destination MAC address and forwards the frame only to the port where that MAC was learned, keeping traffic within the same LAN.
