Referring to the exhibit, which statement is correct?
A.
The local device is using a bridge priority of 4k.
B.
The root bridge is using a bridge priority of 4k.
C.
The root bridge has not been elected for this RSTP topology.
D.
The local device is the root bridge for this RSTP topology.
The Answer Is:
D
This question includes an explanation.
Explanation:
In a Rapid Spanning Tree Protocol (RSTP) topology, the root bridge is determined by the switch with the lowest bridge priority value 1 2 . If all switches have the same priority, then the root bridge is assigned to the switch whose MAC address’s hex value is the lowest 2 . The default bridge priority value is 32768 3 2 . However, without the actual exhibit, it’s difficult to definitively determine which device is the root bridge. But based on the options provided, if we assume that the local device has a lower bridge priority or a lower MAC address than other devices in the network, then it could be considered as the root bridge for this RSTP topology 4 5 .
