AI-901 Azure AI Fundamentals Practice Tests: 5x45 Explained

EXAM SIMULATOR, NOT A VIDEO COURSE. Every minute here is spent on exam-style questions: timed like the real exam and reviewed option by option. Use it after you have studied, to find out whether you are ready and exactly where you would lose marks.

WHY THESE EXAMS

• 5 full length practice exams, 225 original questions, each exam 45 questions in 45 minutes with a 70 percent pass mark, the same shape as the Microsoft AI-901 Azure AI Fundamentals exam.

• Written for AI-901, the exam that replaces AI-900: Microsoft Foundry, Azure OpenAI models, Content Understanding, agents and responsible AI as listed in the current study guide, not the old AI-900 outline.

• Every answer option explained, not only the correct one, with a key takeaway and a link to the Microsoft Learn page behind the question.

• Every question tagged with its skill area, so practice mode lets you drill one area at a time, and the results page shows where you lose marks.

• Scenario questions with exhibits: service comparison tables, model selection flowcharts and confusion matrices, so you practise reading an exhibit under time pressure like the real exam. Multi-select questions included in a similar proportion to the real exam, with the number of correct answers stated.

WHAT IS COVERED. The two skill areas of the official AI-901 study guide, weighted evenly: Identify AI concepts and capabilities (machine learning types and model evaluation, computer vision, natural language processing, speech, document and content understanding, generative AI, responsible AI principles) and Implement AI solutions by using Microsoft Foundry (choosing models and services, Azure OpenAI, Vision, Language, Speech, Content Understanding, Content Safety, prompt engineering, grounding and agents). The five exams build on each other: the first covers both areas at the level of the study guide, the middle three go deeper into the areas candidates most often confuse (which responsible AI principle a scenario violates, classification versus regression versus clustering, which Foundry service fits a task, prompt techniques and grounding), and the last is a harder mixed review.

HOW THE QUESTIONS ARE WRITTEN. Most questions put you in a situation a team actually faces: a bank must explain a loan decision, a retailer wants to read receipts automatically, a support desk wants an assistant grounded in its own documents. You read the exhibit or the scenario, then choose the option that Microsoft Learn supports. Distractors are plausible mistakes, not obvious wrong answers. Every question was written for this course from the official study guide and Microsoft Learn; none are copied from the real exam or from any exam dump, and we never claim that any question matches a real exam question.

HOW TO USE THEM. Take Practice Test 1 in exam mode to get a baseline. Review every explanation, including the options you got right. Use practice mode on your weakest skill area, then take the next exam. Aim for a stable score above 80 percent before you book the real exam.

SUPPORT. Every explanation ends with a question code. If you think an answer is wrong or outdated, post the code in Q&A and we will check it against Microsoft Learn and correct it.
