Thank you to everyone on this forum for all their invaluable feedback, especially the guys that worked on the CertifyChat November VCE and PDF files. There are some wrong questions, but they are both still valid to pass with. 95% of my exam was in the dump. This was my 2nd time taking the test. The first time I failed using just the ExamCollections Premium VCE file. (Jan 2016) I would strongly not rely on that VCE file alone. The 70-413 exam is not easy and both times I took the test, there were some new and slightly re-worded tests. If you study the dumps and have a solid understanding of the topics, you will pass this exam. Good luck everyone!
