Refer to the exhibit. Given the output shown from this Cisco Catalyst 2950, what is the most likely
reason that interface FastEthernet 0/10 is not the root port for VLAN 2?
A.
This switch has more than one interface connected to the root network segment in VLAN 2.
B.
This switch is running RSTP while the elected designated switch is running 802.1d Spanning
Tree.
C.
This switch interface has a higher path cost to the root bridge than another in the topology.
D.
This switch has a lower bridge ID for VLAN 2 than the elected designated switch.
Explanation:
This question is to check the STP technology.
When STP is running in a network with loops, ports will transition into the forwarding state or the
blocking state. Here decisive factor is the cost to reach the root bridge, the port with the higher
cost is in the blocking state, while the port with the lower cost is in the forwarding state.
