Question 107/142
In STP, the bridge ID on the switching network is as follows. With which of the following bridge IDs is the switch selected as the root bridge?
Correct Answer: B
Comprehensive Explanation: In STP, the switch with the lowest Bridge ID is selected as the root bridge.
The Bridge ID consists of the bridge priority and the MAC address. In this case, the switch with the bridge priority of 4096 has the lowest Bridge ID, making it the root bridge. If two switches have the same bridge priority, the MAC address is used to break the tie, with the lower MAC address winning.
