Were you in the situation to find some of the exam questions ambiguous? For example if I am to follow strictly the requirements of one of the questions in my last exam, my configuration in the laboratory is not working. Do you have any hints how can I officially get clarification about this question? By now I've wrote to the "training" email address and I'm waiting for an answer.
I've come across a couple of questions that were somewhat vague for Satellite, but I wouldn't say that they were ambiguous. As a matter of fact, I've filled in the feedback form that was available for those sections during a Red Hat exam.
