you got a link to the the tcp/ip port numbers breh???A lot of troubleshooting questions and a couple simulations. Know the tcp/ip port numbers by heart. Also the 802.11 wireless frequencies. I didnt get a lot of hardware questions other than printers. I failed my first shot because i overlooked troubleshooting and was focused on memorizing pin counts and shyt then my test ended up being 60% troubleshooting. Passed on the second try. Good luck
