When I took the exam there was one question where the conditions given eliminated all the of possible answers. So I picked the answer that violated just one of the conditions and would be the least disruptive in a production environment. I described the problem in more detail during the comments section.

I did not pass, and next time the same question came back! While I was able to go home and research correct answers to some questions I remembered and was unsure of, I have no idea if I got this one right or not, and if not, I don't know how to know which answer they considered "right."
