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?

Show Suggested Answer Hide Answer
Suggested 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.

I believe the bridge ID with the lowest value is selected, but I can't recall if the MAC address affects the decision if the priorities are the same.

I’m a bit confused about the priority numbers. Is 32768 always the default? I feel like I’ve seen different values in practice questions.

I remember practicing a similar question where we had to compare bridge IDs. I think the one with the lowest priority wins, so it might be A or C.

I think the root bridge is determined by the lowest bridge ID, but I'm not sure how the priority values play into that.
