If two switches are configured with the same priority and the same extended system ID, what determines which switch becomes the root bridge?
- the lowest IP address
- the MAC address with the highest hexadecimal value
- the highest BID
- the Layer 2 address with the lowest hexadecimal value
Explanation: When other factors are equal, the switch with the lowest MAC address will have the lowest BID, and will become the root bridge. STP functions on Layer 2 and does not use IP addressing as a factor.
