So whoever exactly you work for's IT will become a little less secure in the near future?
That's the funny (not really) part, the stuff I learned for this certificate has very little to do with my actual job. We deal with cryptography, and that was on there, but not the equipment/software I deal with. I don't actually do IT, or at least not what is commonly thought of as "IT".
DRSN (Defense Red Switch Network) is what I do.
Get plenty of sleep (but not too much to eat) before the test.
You'll do fine.
I was up all night (working...well, studying actually) and took the test in the morning. My co-workers thought I was nuts too, but that was the easiest way...or at least I thought so.
