Exactly. I've had several candidates that I have passed who on the TCP question have said "I don't know, networking is not my strong point." That's great! Knowing when you don't know something and should just move in is a real strength. As long as someone does fine on most of the rest of the questions, having one or two gaps in knowledge is not a problem, I can tell from the other questions that they'll be able to pick it up if they need it, or ask for help when they need it.
