I have a job interview tommorrow for a network technician spot and I was wondering if anyone knows a quick website where i can cram some information about the hardware and stuff all on one site. school was a blur and I dont want this guy to think I'm an idiot, cause I know a decent amount of stuff. I just don't know one centralized spot to review it all. Thanks in advance!


hubs routers switches VPN blahbittyblah <- well I know alot about all of those but I know this guys going to sneak attack me.

I don't really know if there's a central nervesystem for this kind of thing, but I can definitely recommend browsing some sites like the cisco site, juniper perhaps, ... Blackbox

Might be a good approach to sneak-attack him on the latest heads-up in the world of networking by checking out what's new with these leading brands.

I know it's kinda late to reply to this, but I wish you the best of luck
and if you have any questions, feel free to ask now... (I'll do my best to help)

jlew, thanks.... good to know

i have till 3PM tomorow...that one link was good, thanks... and I'm going to sneak attack him with the new wave of equipment shit. make it sound like i know what im talking about. I'm afriad hes going to ask me to subnet or something like that and ill be like hmmmmmmmm yeaaaaaa can i sign online?

subnetting's piece of cake no?

just keep in mind what class your address is.
A : 8 network bits, leaving 24 hostbits
B : 16net , 16 host
C : 24 net, 8 host
D : not important, as it's mostly used for testing and not frequently encountered in real-life situations

So, proceed as follows
1) determine the amount of subnets you need. (ex. 10)
2) calculate how many bits you need to form these(10).... (here: 4, as that gives you 16 subnets*14, as you cannot use 1st and last(net address and broadcast)*, while 8 is not enough)
3) divide the host-portion of the address (mask) into subnet-and host portion (here, 50-50)
4) binary calculus gives you every available subnet. (0001, 0010, 0011, ..., 1110)
5) fill the host-portion using the same logic from 4)

Whoa, I'm totally confused dude.
It's been so long. I just use a subnet calculator if I need to.

All I remember was that it was way easier converting to binary first.

I have the ExamCram book for CCNA, it comes with a CD containing the book in PDF, Practice Questions and a Router Sim. That's my best advice to learn it, I found it just as comprehensible as Cisco's online course, but much cheaper

EDIT: My bad, I have the Sybex book

I actually assumed it had allready been converted to binary, as you see me talking/typing about bits...

From then on, most of the steps actually apply to the subnet mask.
Departing from that mask, you can begin to write down all available subnets.
You can check with cisco, juniper, whatever you please.

If it isn't quite clear, let me know precisely which steps aren't quite well explained.

I would say be honest. If you don't know something don't BS your way through and sound like an idiot. That's the fastest way to kick yourself out of the running. Make it seem like you're really into the job and completely willing to find the answers you don't know. Beyond that, a base knowledge will get you through.

Heh, no that's cool. I'll figure it out when I need. Sorry I'm not much help :(
