AI-901 Practice Exam: 40 Free Practice Questions with Answers
This article is the natural next step: a free AI-901 practice exam with 40 questions and answers, so you can test what you have learned.
In a previous article, I shared my personal experience passing AI-901. Based on that, I started writing a full study guide and exam preparation for the new Microsoft Azure AI Fundamentals exam, the one now replacing AI-900. You can find both here:

⚠️ These are original practice questions, written from Microsoft's published AI-901 skills outline and my own exam experience in July 2026. They are not real exam items. The exam is new and can still change, so use this for preparation, not as a guarantee.
How this works? Substack has no quiz tool, so all 28 questions come first, grouped into three sections. The answer key sits at the bottom of each section.
The exam breaks into three areas, so this practice test does too:
Responsible AI: 8 questions
AI concepts and workloads: 22 questions
Microsoft Foundry and Azure OpenAI: 10 questions
