Refer to the exhibit.
Which two statements are true of the interfaces on Switch1? (Choose two.)
A.
Multiple devices are connected directly to FastEthernet0/1.
B.
A hub is connected directly to FastEthernet0/5.
C.
FastEthernet0/1 is connected to a host with multiple network interface cards.
D.
FastEthernet0/5 has statically assigned MAC addresses.
E.
FastEthernet0/1 is configured as a trunk link.
F.
Interface FastEthernet0/2 has been disabled.
Explanation:
Carefully observe the information given after command show. Fa0/1 is connected to
Switch2, seven MAC addresses correspond to Fa0/1, and these MAC are in different VLAN.
From this we know that Fa0/1 is the trunk interface.
From the information given by show cdp neighbors we find that there is no Fa0/5 in CDP
neighbor. However, F0/5 corresponds to two MAC addresses in the same VLAN. Thus we
know that Fa0/5 is connected to a Hub.Based on the output shown, there are multiple MAC addresses from different VLANs
attached to the FastEthernet 0/1 interface. Only trunks are able to pass information from
devices in multiple VLANs.
From the answer explanation: “Thus we know that Fa0/5 is connected to a Hub”… or a desktop low-end Cisco switch… or an higher-end non-Cisco switch… or a full-fledged Cisco switch with CDP disabled.
Well, I hope I’ll not face such kind of question in the real exam, and suppose that for the time being one should assume that there no other switches than Cisco Catalyst ones and that CDP is always enabled (if something does not appear in “cdp neighbors”, it does not exist!).
