Well, if you can discuss the exam with someone and not "reveal in whole or in part any exam questions, answers, problems or solutions to anyone during or after the exam whether orally, in writing, or any Internet chat rooms, or otherwise", then go for it (underline emphasis is mine). I'm not sure how you can talk to anyone about it without breaking this agreement.
But back to my original point. I'm sure they wouldn't be surprised if you and a couple buddies go get a beer afterwards and compare notes. But if you share on a message board that you and your buddies got a beer and talked about the exam, you shouldn't be surprised if they contact you.
