CCNA Exam question

Here is a question that was twice on a CCNA exam:

PC1--------> R1 ---------> R2 ---------> SW---------->PC2

You can see the IP for PC2 and you can log only on R1 via PC1

The exam asks to connect PC1 with PC2

1. Log on R1 and find the IP  of R2 with:
#sh cdp neigh details

note: it's important to use "details" otherwise you won't be able to see the
IP for R2.

2. Telnet to R2 and run a #sh cdp neigh details, but that will not help you
get the IP of the switch.
Apparently, the switch has not been assigned an IP.

I am not sure if you will be able to ipconfig /all on PC2.

Enable routing and adding the networks did not help. ...

It's a nice simulation to waste your time and stay behind with the rest of
the questions.

If you can reach R2, then we assume R1 is configured OK.
Once on R2, don't worrry about the switch unless interVLAN routing is
involved.
Check  the R2<-->SW interface and Configure with the right ip (you know
PC2's ip).
Config routing on R2
Check routing on R1.
Ping PC2 from PC1

You can assume that the switch will have little or no part to play with the
fault as inter vlan routing will not be in a simulation in the exam for
CCNA - you should concentrate on the routers. Normally one of the routers
will be configured ok you can do a show run on the working one and on the
broken one to quickly find out what to do. I had a similar question on the
CCNA few months ago.

Thanks for the answer.
Do you mind expanding a little on "Check  the R2<-->SW interface and

Both have to be on the same subnet and if you know PC2's default gateway
then use that as the router's IP.
