What if I told you I saw that question recently on my CCIE written
test......then would it still be a CCNP question??? But of course I wouldn't
due that because of the NDA....:-)

I think this is actually more of a CCNP troubleshooting
question. Think
about the type of media you're dealing with. Collisions
happen on media
that allow multiple devices to speak at the same time. If
the media or
topology does not allow multiple access then you cannot have
collisions.
On most serial links, you are running full duplex with only
two
devices. This makes it impossible to have collisions. They
just don't
apply in this situation. Heck, even in situations where you
can run
half-duplex serial I don't know what happens when both
stations transmit
at the same time. I've never personally experienced a
half-duplex
serial link, I've just heard that they exist.
HTH,

Can you have collisions on a serial link? Thanks again.
