Technical questions from my interview

I just had a phone interview for a Jr. Network Engineer position that is Cisco focused and wanted to share the technical questions that I was thrown. I figure those hanging around this forum would be interested to know.
1) Explain the difference between a collision domain and broadcast domain.
2) How would you configure a trunk port on a switch?
3) How would you allow only certain VLANs to traverse a particular trunk?
4) Which routing protocol are you most comfortable with? How would you set that up on a router?
5) How would you list the contents of a directory from a linux command line? (Because I listed basic linux/unix skills)
That's all there was to it. I drew a blank on the command for question 3, but still got the job. It's hell not knowing what kind of questions you might get. That's always one of the most nerve racking parts of interviews for me.

I think ccnp switch covers trunk allowed vlan list only, so you did really good, and congrats for the job! -

That doesn't sound right, "switchport trunk allowed vlan" was in the CCNA I'm sure.Work In Progress: CCIE R&S Written

Excellent! Thanks for posting these questions. It helps a lot to know that I'm actually learning something while studying for the CCNA. -

Yea, at the end of the interview I asked the guy what the command was for the one I blanked out on.
I wanted him to know that when I don't know something, I make a point of finding out. CISSP | CCNA:R&S/Security | MCSA 2003 | A+ S+ | VCP6-DTM | CCA-V CCP-V -
