Good question. These certification exams all include a non-disclosure or confidentiality agreement. In any case, I don't think this could be the result of test-takers recalling questions from memory. We're talking about seeing 100-150 questions, and spending only a minute or so with each one, and many questions involve reading a short paragraph. The "dumps" have the questions and answers verbatim. I think it must be the work of unscrupulous employees at the certification vendors or some of the testing centers.
