Assuming only one VLAN in the exhibit, which switch is acting as the root bridge?
A.
Switch3
B.
A root bridge is not required in this network.
C.
Switch1
D.
Switch2
Explanation:
A root switch has all ports in non-blocking mode. Based on the diagram above, Switch1 and
Switch 2 contain ports that have been blocked by the STP process, so Switch3 must be the root
bridge.
