The boson test sim does not make any sense! Or am I just really tired?

The question:

A network engineer has just been hired to work on a small internetwork. The manager gives the new engineer the password to log into switch SW2, telling the new engineer to try to start building a diagram of the network. Based on the command output in the exhibit, which of the following would be accurate items to add to the network diagram?

A picture of three devices:

|Device X| ---- |SW2| --- |Device Y|

A printout of "show cdp neighbour detail"

Possible answers:

A. Label both links as full duplex.
B. If drawing “SW1” where “Device X” sits, label SW2’s left-side interface as Gi0/2.
C. If drawing “R1” where “Device Y” sits, label R1’s left-side interface as Fa0/13.
D. Label R1 as using 10.1.1.1 on its connected interface.
E. If drawing “SW1” where “Device X” sits, label SW2’s left-side interface as Gi0/1.

WTF? Correct answers should be A, B, D - but I don't even understand the question! Does this make sense to anyone else? Am I just really tired?

Edit: Is their English just really, really bad? If so, I need another test simulator.

Based on the information given in your question, A couldn't be correct, as we aren't given enough information on what Device X and Device Y are. Perhaps they're hubs, in which case neither link will be full duplex. (see note below however)

I think this question is testing you on knowing cdp. If

A printout of "show cdp neighbour detail"

actually showed something like

Device ID: S2
Entry address(es):
IP address: 192.168.1.51
Platform: cisco WS-C2950-12, Capabilities: Switch IGMP
Interface: Ethernet0/0, Port ID (outgoing port): FastEthernet0/1
Holdtime : 168 sec
(etc)

Then it's testing you on being able to assemble a network diagram just by cdp: is e0/0 a port on S2 or a port on the device running the show cdp neighbors command? Is the IP address the local port or remote port?

EDIT:
OK, a google search found me the question and yeah, this is strictly being able to interpret the output of show cdp commands.

A is correct as the two devices show cdp neighbors lists are a router and switch. Both will support full duplex links between SW2 and themselves.

B is correct because part of the output is

Device ID: SW1
...
Interface: GigabitEthernet0/2, Port ID (outgoing port): GigabitEthernet0/1

This shows SW2's port is gi0/1, connecting to SW1's gi0/2 port, so on your diagram if you were to mark Device X as SW1, you'd also mark the connecting ports as such.

D is correct because part of the output includes

Device ID: R1
Entray address(es):

---

IP address: 10.1.1.1
...
Interface: FastEthernet0/13, Port ID (outgoing port): FastEthernet0/1

Which shows SW2's FA0/1 is connected to R1's FA0/13 port, which is assigned ip address 10.1.1.1.
