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.
This is wrong – the only time you will see a port as ALTN is when it is an alternate path to the root. As there is no information given as to the cost (media types) of any ports then we must assume that a port number lower than 10 is also connected to the Root. That makes the answer A.
