Microsoft Azure AI Fundamentals (AI-901) is Microsoft’s entry-level AI certification — the 2026 successor to the popular AI-900 exam, which retired on June 30, 2026. It validates your understanding of core AI concepts and your ability to implement AI solutions by using Microsoft Foundry, and Microsoft’s audience profile asks for conceptual knowledge of AI solutions in Azure plus knowledge of Python coding syntax and programming techniques and familiarity with Azure resources, and says you should be familiar with REST APIs, SDKs, and CLIs. Expect roughly 40 to 60 questions in 45 minutes, with a passing score of 700 out of 1000. AI-901 is a genuine replacement rather than a refresh: the outline was rebuilt around Microsoft Foundry, and 55 to 60 percent of the exam is now hands-on implementation.

Practice questions are the highest-leverage way to prepare: they show you how concepts get tested, expose the gaps you didn’t know you had, and make the real exam feel familiar. The free quiz below works like the real thing — multiple choice with plain-English explanations — and every question explains why the answer is right, which is where the actual studying happens.

What’s on the Azure AI Fundamentals exam

Microsoft’s skills-measured outline (dated April 15, 2026) covers just two areas, and the balance is the important part: most of AI-901 is hands-on work in Microsoft Foundry. Our question set is mapped to these weights, so your practice score roughly tracks how the real exam distributes its questions:

Skill area	Exam weight	What it covers
Identify AI concepts and capabilities	40 to 45%	The six responsible AI principles (fairness, reliability and safety, privacy and security, inclusiveness, transparency, accountability); how generative AI models work; choosing an appropriate model based on capability; deployment options and configuration parameters such as temperature, top_p and max tokens; and identifying workloads across generative and agentic AI, text analysis, speech, computer vision, and information extraction
Implement AI solutions by using Microsoft Foundry	55 to 60%	Writing effective system and user prompts; deploying a model and working with it in the Foundry portal; building a chat client with the Foundry SDK; creating and testing single-agent solutions; text and speech solutions including Azure Speech in Foundry Tools; vision and image generation with multimodal models; and extracting information from documents, forms, images, audio and video using Azure Content Understanding

How to prepare for the Azure AI Fundamentals exam

Microsoft offers free self-paced learning paths on Microsoft Learn for Azure AI Fundamentals, plus an official practice assessment. A study loop that works: read the skills-measured study guide, take a practice set like the one above, then study the areas where you missed questions. Implementing AI solutions in Microsoft Foundry is by far the most heavily weighted area at 55 to 60 percent, so make sure you are comfortable in the Foundry portal, reading Python that uses the Foundry SDK, and working with agents and Azure Content Understanding. New to the concepts? Our plain-English AI glossary and explainer on how AI models actually work cover the fundamentals.
