I have found many come from Cisco. They live from earlier IOS versions
but the documentation doesn't get updated. They have also come from
Cisco Academy and other Cisco training. I know many people (I used to
be part of it too) believe the 10 MB interface can't trunk. This
requirement is still seen in Cisco documentation.

What is interesting to me about these myths is how they get started in
the
first place and even more perplexing is how they survive. As Brian
pointed
out, in most cases they can be disproved in 5 minutes on the command
line.
Yet the admin distance 0 myth that I cited can be found in such
respected
sources as Doyle and Caslow/Pavlichenko and the ones Brian lists are
equally
widespread. Weird.

I fully agree with Brian on these. These questions or "gotchas" likewise
here
are probably worth memorizing if this was more or less of a written exam
pin pointing out how much you know about the specifics. But the lab is
result
oriented so whatever you type on the router should give you hints as to
what
is going on :)
