AI-901 Azure AI Fundamentals (2026): 500 Practice Questions

Are you ready for Microsoft exam AI-901, Azure AI Fundamentals? These five practice tests are built to answer that question honestly, before you book the exam. You get 500 questions, fifty per test, written against the current study guide with its skills measured as of April 2026.

That matters more than it sounds: AI-901 replaced the retired AI-900 exam and dropped the classic machine learning domain entirely. The syllabus is now built around Microsoft Foundry, formerly Azure AI Foundry, and the Foundry Tools that used to be called Azure AI services. Practice material written for AI-900 will send you into the exam prepared for the wrong test.

The five tests get progressively harder, on purpose. Test 1 covers the core of every objective with short, single-concept questions. Test 2 moves to realistic scenarios where the wrong answers are the services that genuinely get confused with each other.

Test 3 gives you two defensible options and one constraint that decides between them. Test 4 goes into implementation detail: parameters, portal steps, SDK requirements and service limits. Test 5 is a full simulation at real exam pace, fifty questions in forty-five minutes, with the domains mixed and several constraints per question.

Every question is explained twice over. Each answer option has its own feedback telling you why it is right or wrong, and what that wrong option actually is, so you learn the distinction rather than the answer. Each question then closes with a full explanation and a link to the Microsoft Learn page it came from, so you can read further where you need to.

Results are scored per exam domain, so a weak score tells you exactly where to spend your remaining study time. The pass mark is set at 80 percent, and 85 percent on the final simulation, deliberately above the real exam's bar: passing at your own desk should mean you have margin to spare on the day. These are practice tests with explanations, not a video course.

They work best alongside the free Microsoft Learn learning paths for AI-901. Frequently Asked QuestionsAre these real exam questions? No.

All questions are original and based on the official exam objectives. They match the style, difficulty and topic weighting of the real exam, without copying it. How do the five practice tests work?
