Question:
What is the value used to determine which port on a non-root bridge will become a root port in a STP network?

• the path cost
• the highest MAC address of all the ports in the switch
• the lowest MAC address of all the ports in the switch
• the VTP revision number

Explanation: STP establishes one root port on each non-root bridge. The root port is the lowest-cost path from the non-root bridge to the root bridge, indicating the direction of the best path to the root bridge. This is primarily based on the path cost to the root bridge.
