Very update questions. I bought the dumps 3 days ago because I saw the update date was just on that day. I took the questions to my friend (he just took the exam) and he said these were new questions. And I just passed my exam a while ago. Can't wait to share my great experience with you all. I got 98% of the full score. I think I missed one question about network. The dumps from this site is really valid and accurate one. Already recommended it to all.

Passed my exam with this dumps. Really recommend. The questions are valid and answers are accurate. The only shortcoming is there are too many questions and you need to spend lots of time to prepare with the questions. But compare to pass the exam and get certified, it's only a piece of cake.
