About the Azure AI Fundamentals (AI-900) Exam

Quick Answer: The AI-900 exam has a 45-minute time limit and requires 700/1000 to pass; Microsoft does not publish its question count (most Microsoft exams have 40-60). It covers five domains spanning AI workloads, machine learning, computer vision, NLP, and generative AI on Azure. The exam cost $99 USD with no prerequisite certifications required. Microsoft retired it on June 30, 2026; AI-901 replaced it.

The Microsoft Azure AI Fundamentals (AI-900) certification validates your foundational understanding of artificial intelligence and machine learning concepts, as well as related Microsoft Azure services. Unlike associate-level certifications such as the AI-102, the AI-900 is a conceptual exam — it tests your understanding of what AI services do and when to use them, not your ability to write code or build solutions.

This certification is ideal for both technical and non-technical professionals who work with or around AI-powered solutions. Whether you are a business analyst evaluating AI capabilities, a project manager overseeing an AI initiative, or a developer beginning your AI journey, the AI-900 establishes your foundational AI knowledge on the Microsoft platform.

Exam Format at a Glance

Domain Breakdown

On the Exam: Following the May 2, 2025 exam update, Generative AI (20-25%) is the single heaviest domain — the machine-learning domain's weight was reduced and the generative-AI weight increased. The other four domains are each 15-20%. Combined, Generative AI plus Machine Learning can account for 35-45% of the exam, and Computer Vision plus NLP form another 30-40%. Responsible AI principles appear across ALL five domains, not just Domain 1.

Exam Retirement Notice

Important: Microsoft retired the AI-900 exam on June 30, 2026. You can no longer take AI-900; the replacement exam is AI-901, which now earns the Azure AI Fundamentals certification.

What this means:

• New candidates take AI-901
• Certifications already earned through AI-900 remain valid; Fundamentals certifications don't expire

Question Types Explained

Multiple-Choice (Single Select)

You are presented with a question and four answer options. One answer is correct. These often test your ability to identify the correct Azure AI service or concept for a given scenario.

Multiple-Answer (Multi-Select)

You are given a question with five or more options and asked to select two or three correct answers. Common for questions asking you to identify multiple responsible AI principles or Azure AI service capabilities.

Drag-and-Drop (Matching)

You may need to match AI concepts to their definitions, Azure services to their capabilities, or machine learning types to their use cases.

Yes/No Statement Groups

A set of related statements where you must evaluate each as true or false. These test your ability to distinguish between similar concepts.

Scenario-Based

A short scenario (1-2 paragraphs) followed by a question. These test your ability to identify the appropriate AI approach, Azure service, or responsible AI consideration for a business scenario.

Tip: Unlike the AI-102, the AI-900 does NOT include case studies. All questions are standalone, and you can navigate back and forth between questions. Use this to your advantage — flag uncertain questions and return to them.

Who Should Take This Exam?

The AI-900 is designed for professionals who:

• Business stakeholders evaluating AI opportunities and understanding AI terminology
• Project managers overseeing AI-related projects who need foundational AI knowledge
• IT professionals beginning their AI and cloud journey
• Sales and marketing professionals working with AI-powered products
• Students pursuing a career in AI, data science, or cloud computing
• Developers who want a broad understanding of AI before specializing
• Anyone curious about AI and how Azure implements AI services

Prerequisites

Microsoft states there are no formal prerequisite certifications for the AI-900. The exam is designed for both technical and non-technical audiences. However, familiarity with the following is helpful:

• Basic understanding of cloud computing — what cloud services are and how they differ from on-premises solutions
• General awareness of AI concepts — what AI, ML, and deep learning mean at a high level
• Ability to navigate the Azure portal — understanding how to find and explore Azure services (helpful but not required)
• No programming required — unlike the AI-102, the AI-900 does not test coding skills

On the Exam: The AI-900 intentionally avoids code-level questions. You will never need to write Python, C#, or API calls. Questions focus on concepts, service selection, and responsible AI principles.

Scoring

The exam uses a scaled scoring model ranging from 1 to 1,000. The passing score is 700. The scaled score does not translate directly to a percentage — a score of 700 does not mean you answered 70% of questions correctly. After completing the exam, you receive a pass/fail notification on screen immediately. Your detailed score report showing performance by domain is available in your Microsoft Learn profile within minutes.

Certification Renewal

Azure AI Fundamentals is a Fundamentals certification: it does not expire and has no renewal assessment.

Career Path

Career Tip: The AI-900 is an excellent entry point, but to demonstrate hands-on skills to employers, pursue the AI-103 (Azure AI Apps and Agents Developer Associate) or AI-300 (Machine Learning Operations Engineer Associate) as your next certification. The AI-900 alone signals awareness; associate-level certs signal capability.
