The exam

What is the AI-900 exam?

AI-900 was the original exam for Microsoft Certified: Azure AI Fundamentals. Microsoft retired it on 30 June 2026, so it can no longer be scheduled. AI-901 is now the route to the Azure AI Fundamentals credential. This page and its question bank remain available as reference material for the former AI-900 outline.

The exam doesn't ask you to write Python or design a model architecture. It expects a clear conceptual map of AI workload types (computer vision, NLP, document processing, generative AI), the six responsible-AI principles, the difference between regression, classification, and clustering, and which Azure AI service matches a given scenario — Azure AI Vision, Azure AI Language, Azure AI Speech, Azure OpenAI, Microsoft Foundry. The May 2025 outline added significant generative-AI coverage, so a recent question bank matters more than for older fundamentals exams.

Microsoft last updated the AI-900 skills outline on 2 May 2025. Every question in Azure Mastery's AI-900 bank is mapped to that final outline. Read the archived official outline at learn.microsoft.com.

AI-900 exam objectives

Five domains, with weights set by Microsoft's May 2025 update. Every domain summary below is paraphrased from the official skills outline; the bullet-level objectives in Azure Mastery are tagged so you always know which domain you're being tested on.

Aura presents a visual map of data, models, agents, and responsible AI skills.
AI & agent skill map

AI workloads and considerations15–20%

Explore key topics

The conceptual foundation. Identifies the four common AI workload types (computer vision, natural language processing, document processing, generative AI) with example scenarios for each, and walks through Microsoft's six guiding principles for responsible AI — fairness, reliability and safety, privacy and security, inclusiveness, transparency, and accountability. Expect scenario questions like "which responsible-AI consideration applies here?" Around 6–12 questions per sitting.

Fundamental principles of machine learning on Azure15–20%

Explore key topics

Common ML techniques (regression, classification, clustering, deep learning, the Transformer architecture) and core concepts (features and labels, training and validation datasets). Covers Azure Machine Learning capabilities: automated ML, the data and compute services, and the model management and deployment story. You don't write code — you identify the right technique for a given scenario. Around 6–12 questions.

Computer vision workloads on Azure15–20%

Explore key topics

Distinguishing image classification from object detection from optical character recognition (OCR) from facial detection — and matching each to the right Azure service. Covers the Azure AI Vision service and the Azure AI Face detection service: what each can do, what each is restricted from doing (Limited Access policies for Face), and which scenario maps to which. Around 6–12 questions.

Natural Language Processing (NLP) workloads on Azure15–20%

Explore key topics

The NLP scenario taxonomy: key phrase extraction, entity recognition, sentiment analysis, language modelling, speech recognition and synthesis, and translation. Maps each scenario to the right Azure tool — Azure AI Language for text analysis, Azure AI Speech for spoken-input/output. Around 6–12 questions.

Generative AI workloads on Azure20–25%

Explore key topics

The largest domain by typical question count, reflecting the May 2025 outline update. Covers what generative AI models are, common scenarios (chat, code, image generation, summarisation), and responsible-AI considerations specific to GenAI. Service coverage includes Microsoft Foundry, Azure OpenAI Service, and the Microsoft Foundry model catalog — what they offer and how they differ. Around 8–15 questions.

Frequently asked

AI-900 FAQs

Can I still take the AI-900 exam?

No. Microsoft retired AI-900 on 30 June 2026, so it can no longer be scheduled. AI-901 is now the exam route to the Azure AI Fundamentals credential.

What replaced AI-900?

AI-901 replaced AI-900 on 1 July 2026. It remains the route to Microsoft Certified: Azure AI Fundamentals and adds a more implementation-oriented focus on Microsoft Foundry and Python examples.

What happens if I already passed AI-900?

An Azure AI Fundamentals credential earned through AI-900 remains on your Microsoft Learn transcript. AI-900 itself is retired and cannot be retaken.

Are AI-900 practice questions still useful?

Yes, as reference material for core AI, machine-learning, vision, language, and responsible-AI concepts. New candidates should study the current AI-901 outline and use the AI-901 bank for exam readiness.

AI-900 vs AI-102 — which should I take first?

AI-900 first, unless you already build AI applications professionally. AI-900 is the conceptual map: it teaches you the vocabulary (image classification vs object detection, key phrase extraction vs entity recognition, regression vs classification, the Foundry model catalog) without expecting you to write code. AI-102 is the role-based Associate exam — it expects hands-on Python, REST API calls against Azure AI services, and prompt-engineering against Azure OpenAI. Most candidates pass AI-900 in a few weeks, then spend two to three months on AI-102.

Is AI-900 worth taking if I'm not technical?

Yes — that's a large part of the audience. Microsoft positions AI-900 for both technical and non-technical candidates: solution consultants, sales engineers, technical PMs, business stakeholders evaluating Azure AI procurement, and anyone wanting a credible answer to "which Azure AI service should we use for this?" The exam doesn't ask you to write Python. It asks you to recognise scenarios — "which Azure AI service is best suited for redacting PII from a document?" or "which guiding principle of responsible AI applies here?" — and pick the correct option.

Is Azure Mastery free for AI-900 prep?

The app is free to download and includes a free allowance of AI-900 questions so you can try every feature. The full bank of 340 AI-900 practice questions unlocks with a one-time exam-pack purchase, or you can unlock every exam in the catalogue with a subscription or a one-time lifetime upgrade.

Does AI-900 practice work offline?

Yes. Question practice, scoring, and the readiness prediction all run on-device, so you can study on a flight or a commute with no connection. No account is required, and your study data stays on your device with optional private iCloud sync.

Is there an AI-900 practice test mode?

Yes — timed practice sessions use original, blueprint-aligned questions, published timing guidance, and supported interactive item types. Adaptive study sessions and Focus Weak Spots then target the domains where your accuracy is lowest.
