AI-901 Study Plan: How to Prepare for Azure AI Fundamentals

Most people prepare for AI-901 in two to four weeks of steady study, weighted heavily toward Microsoft Foundry. The plan is different from AI-900's: because more than half the exam is hands-on, you cannot read your way through it. Spend most of your time in the Foundry portal, keep the concept half lighter, and test yourself until your practice scores are consistently clear of the pass mark. Here is how.

How long you actually need

AI-901 assumes a little more than AI-900 did — some comfort with Azure and basic Python — so timelines depend on that starting point:

• New to Azure and coding: about 4 weeks at 4–6 hours a week, with a real share of that time spent clicking through the Foundry portal, not just reading.
• Some Azure or Python background: 2–3 weeks. The concept half will feel familiar; the time goes into hands-on Foundry practice.
• You already build with Azure: 1–2 weeks, mostly to map what you know to the exam's specific Foundry tasks.

The right length is however long it takes your practice scores to settle — not a fixed number of days.

The plan, weighted to Foundry

AI-901 has two areas, and the split should shape your schedule:

1. AI concepts and capabilities (40–45%) — the lighter half to study, even though it is nearly half the marks, because it is mostly understanding: responsible-AI principles, how generative AI models work, and recognizing the main AI workloads. Learn this first; it is the vocabulary the Foundry half uses.
2. Building AI solutions with Microsoft Foundry (55–60%) — where most of your time should go, because it is hands-on. This is the larger half and the one people underestimate.

A workable rhythm: spend the first stretch getting the concepts straight. Then spend most of your remaining time actually doing things in Foundry — deploying a model, sending prompts, building a small app, running a document through the tools.

The hands-on habit AI-900 never needed

This is the biggest change from AI-900, which you could pass on concepts alone. For AI-901, if you have never opened the Foundry portal, you are not ready — no matter how much you have read. If you are not sure what Foundry even is yet, start with our plain-English Microsoft Foundry primer, which covers exactly the parts the exam tests; then come back here to schedule the practice.

Treat each Foundry task in the skills outline as something to do once, not just read. Deploy a model, write a system prompt, build a lightweight chat client, create a single agent, and run text or a document through the tools. Each one you have actually done is a cluster of questions you no longer have to guess at.

Which free official resources to use

• The free learning paths on the exam page, which include hands-on exercises in Foundry.
• The skills outline in the study guide — use it as a checklist of Foundry tasks to have done.
• A free Azure account, so you can actually sign in to the Foundry portal and practice.

Note that Microsoft's own practice assessment for AI-901 is not yet available, so plan to get your question practice elsewhere for now.

How to know you're ready

Book the exam when your practice scores say so, not when a set number of days has passed. Aim to score consistently well clear of the 700 pass mark on full-length practice you have not seen before — and make sure the Foundry-heavy questions are where you are strong, not just the concepts.

Our AI-901 practice exams are built against this exact two-domain outline, Foundry weighting included, and every answer links to the official page behind it — so a miss shows you which task to go practice. For an honest read on the exam's difficulty before you start, see is AI-901 hard.
