IBM Data Architect Big data

IBM Certified Data Architect exam was not so easy for me as I have very little time to spend on my preparation, however with the test available here it was comfortable and I was able to not just pass but with good score. Questions I practised were very much similar when it comes to the exam. I think this the best solution available on at this cost, this I can say from my little research before I purchase access here. Overall very satisfied, I suggest to others as well.
