Only two new questions in my exam. All others were learned in the dumps. I do not just prepare for the exam using dumps. I also joined the training courses for about 10 days. The questions are valid. All answers are correct, too. Questions may change in the real exam so you need to read that carefully. So you really need to pay attention to the real question especially the sequence of the options.

I honestly started reading through the questions and re-reading it every night starting one month out from the test. I don't think I saw anything on the test that I didn't see at least tangentially covered in these questions.
