Exam fidelity: Microsoft does not publish a fixed live question count or guarantee a question-type mix for AZ-400. This lane contains multiple-choice and multiple-response exam-style practice. Practice percentages do not reproduce Microsoft's scaled scoring, and difficulty labels describe this site's Expert-level implementation and design complexity rather than a Microsoft-published question rating.
