If two switches are configured with the same priority and the same extended system ID, what determines which switch becomes the root bridge?

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.​
