Bridge priority
Cost
A) Port ID, IP address, MAC address
B) Bridge priority, cost, extended system ID
C) MAC address, bridge priority, IP address
D) Bridge priority, MAC address, port ID

Answer 1

The bridge ID is formed by combining Bridge Priority, MAC Address, and Port ID, which is option D in the question. This identifier is crucial in spanning tree protocols within a network.

Step-by-step explanation:

The three components combined to form a bridge ID are Bridge Priority, MAC Address, and Port ID. This unique identifier is used in network protocols, specifically spanning tree protocols, to prevent loops and choose the root bridge in a network. The correct combination is given by option D) Bridge priority, MAC address, port ID. The bridge priority is a value that helps to determine the root bridge, the MAC address provides a unique identifier for the network device, and the port ID specifies the exact port within a bridge or switch.
