Generally, those who make the ISC2 exams are completely separated from those who develop training materials for it. A large part of that is ensuring the integrity of the exams. I assume the CC follows this model, which applies to the established exams of the ISC2.
Sorry to hear that you were not successful.
@JoePete is correct. ISC2 must keep the exam and trainings separated but they do follow the same outlines, Also note, that ISC2 us NOT allowed to teach the exam. Both teams will use the outlines to develop either the exam or the training. Remember the outline (commonly called the Common Body of Knowledge (CBK)) is intended for folks to be able to understand the subjects that will be taught/tested in each domain. So it logically follows that the questions might be on different subjects in any Domain.
