Thanks...pretty much a refresher, but the questions were not so tough. Like they would throw in something like a scenario where 50 feet of cable going between stations and wireless AP, AP's going through park with TREES (ha ha---big clue), and the signal not ever being established...what could they do? One of the answers of course was that the AP's neede to be high enough above the trees! Other VPN questions were screenshots of SDM outputs, where IPSEC encryptions don't match, or the wrong interesting traffic was put into the ACLs, or something and you had to guess why the vpn can't connect, etc. There were two simlets that asked questions..."what is the gateway for the tunnel?" or "what workstation/range is configured to authenticate and configure the server via HTTP?", and they gave you screens of SDM outputs with only some buttons active. Not too tough. You should take it and put it on your résumé!
