There was not a single topic that was not covered in the mocks. The mocks online covered all types of questions from all the topics and that too in a twisted manner. So I had to stay prepared to attempt the az-400 online exams for unlimited practice. I started comprehending the questions as the style and the multiple choices switched every time I attempted them. So I cannot rely on the memory of the mock but my knowledge of the syllabus of the AZ-400 exam. I invested my time, efforts, and energy into a resource that turned out to be successful in more ways than one.
