After the election of the root bridge has been completed, how will switches find the best paths to the root bridge?

• Each switch will analyze the sum of the hops to reach the root and use the path with the fewest hops.
• Each switch will analyze the BID of all neighbors to reach the root and use the path through the lowest BID neighbors.
• Each switch will analyze the port states of all neighbors and use the designated ports to forward traffic to the root.
• Each switch will analyze the sum of all port costs to reach the root and use the path with the lowest cost.

Explanation: After the election of a root bridge has occurred, each switch will have to determine the best path to the root bridge from its location. The path is determined by summing the individual port costs along the path from each switch port to the root bridge.
