Question

What is the role of the root port in a switched network?

A It replaces the designated port when the designated port fails.
B It replaces the designated port when the root port fails.
C It is the best path to the root from a nonroot switch.
D It is administratively disabled until a failover occurs.

Explanation

In STP, a nonroot switch identifies one root port as its lowest-cost path to the root bridge. That port is the switch’s best route toward the root and is used for forwarding traffic in that direction.
