This is infuriating. These questions are arbitrary, designed to screw you. Every course i followed said that this would be a high level exam and not too technical. I am a marketing rep. damn it, why would i know what the H a blade is? This whole thing is highly deceptive. The MS900 learning path is designed to help you describe something, they do not go into this kind of detail. These types of questions are impossible to answer unless you have preexisting IT experience or actually dive far deeper into the dashboard itself and not only the provided learning materials. The problem here is, it is too much damn information to retain, too many acronyms and technical terms to remember. I failed the first time i took this exam because i panicked with all the stuff i had to remember, in the end the exam won't even cover some subjects. Completely infuriating.
