Exam AI-901 is a proctored fundamentals exam: 45 minutes of exam time, offered in 13 languages, and 700 passes. Microsoft doesn't publish the number of questions (most of its exams have 40 to 60). The fee is set by the country or region (USD 99 in the United States). Fundamentals certifications don't expire, so there is no renewal. Our forms use 50 questions split 21 / 29, close to the midpoints of the guide's ranges.

From Microsoft's certification page and exam guide, checked Oct 18, 2026.

Every task in the exam guide

The exam guide splits each domain into task statements. Each one has a page with a short summary, the lessons that teach it and open sample questions.

Domain 1: Identify AI concepts and capabilities

Domain 2: Implement AI solutions by using Microsoft Foundry

How these questions are made

  • Written by us from the exam guide's task statements and the Microsoft documentation — never from real exam content.
  • Every option carries its own explanation and a link to the Microsoft page that proves it.
  • A question enters a timed exam only after an independent check; until then it is a practice question.
  • Results are a plain percentage, per domain too — not an imitation of Microsoft's scaled score.

Questions about the AI-901 practice exam

Is the AI-901 practice exam free?
Yes. The full practice exam (50 questions, 45 minutes) is free with no sign-up, and so are the 78 practice questions, the task pages and the study path. Your attempts are saved in this browser, on this device.
How many questions does it have, and is it timed?
50 questions in 45 minutes: the real AI-901 pace, scaled to this form. When the time runs out, the exam is submitted as it stands.
Are the answers explained?
After you submit, not during: like the real exam, the timed exam gives no feedback until the end. Then you get your score overall and per exam domain, and every question with each option explained and a link to the Microsoft documentation page behind it. In practice mode an answer is explained as soon as you check it.
What does the Azure AI Fundamentals exam pack add?
3 more timed practice exams (Practice exam 1: 50 questions, 45 minutes; Practice exam 2: 50 questions, 45 minutes; Practice exam 3: 50 questions, 45 minutes), each scored and explained the same way, and the next version of this exam if it changes within your 12 months. 12 months of access. One payment, nothing renews by itself. Everything above stays free. See the pack.
Can I get a refund?
Yes, with no conditions: ask within 14 days of buying and you get the whole payment back. The details are in the terms.
Is this an official Microsoft practice exam?
No. BytePatterns is not affiliated with, endorsed or sponsored by Microsoft. Every question is written by us from the public exam guide and the Microsoft documentation, never from real exam content, and a score here does not predict your result on the real exam. Microsoft lists its own preparation resources on its certification page.
