Azure AI-900 FAQ: Exam Format and Prep

Azure AI-900 FAQ for exam format, topics, prep strategy, practice, and common candidate traps.

Use this FAQ for current Microsoft Azure AI Fundamentals (AI-900) logistics, study questions, and edge cases that can distort your prep if you ignore them.

Quick answers

Question Short answer
Is AI-900 still active? Yes. Microsoft Learn still lists the certification as active on April 13, 2026.
Is it retiring? Yes. Microsoft says the related exam retires on June 30, 2026.
What replaces it? Microsoft says AI-901 will replace AI-900.
How long is the exam? Microsoft Learn currently says you have 45 minutes.
Is it coding-heavy? No. It is concept, workload, and service-selection heavy.
What should I do if my exam date is after retirement? Stop and verify that you should be preparing for AI-901 instead.

What does AI-900 really reward?

AI-900 rewards candidates who can classify the problem before naming a service. Strong answers usually:

  1. identify the workload or concept lane first
  2. choose the right Azure capability family
  3. reject distractors that solve a different problem type

That means the exam is not deep engineering work. It is clean reasoning about what the scenario is actually asking for.

Do I need machine-learning math?

No deep math is expected. You do need to keep the core distinctions straight:

  • classification vs regression vs clustering
  • supervised vs unsupervised learning
  • features vs labels
  • training vs validation vs inference
  • custom ML workflows vs prebuilt Azure AI services

If those boundaries are clear, a large share of AI-900 becomes much more manageable.

Does the Microsoft Foundry rename matter?

Yes, but only in a controlled way. Microsoft’s certification page now says Azure AI Foundry is now Microsoft Foundry and that the exam materials are being updated. The current AI-900 study guide still uses Azure AI Foundry wording. For exam prep, follow the study-guide objective wording first and treat the rename as a current branding transition you should recognize, not as a new objective set.

How should I think about document processing questions?

Start with the business goal:

  • if the task is reading existing text or structure from a form, invoice, or receipt, think document processing
  • if the task is analyzing general image content, think computer vision
  • if the task is creating a summary or draft, think generative AI

This boundary matters because AI-900 likes distractors that sound modern but solve the wrong workload.

What is the smallest useful hands-on baseline?

You do not need a portfolio project, but some direct exposure helps. A strong minimum baseline is:

  • one image-analysis or OCR demo
  • one text-analysis or speech-to-text demo
  • one quick review of Azure Machine Learning as the custom-model platform
  • one grounded generative-AI example so you understand why retrieval context matters

That is enough to make the service boundaries feel real instead of memorized.

What should I do if two answers both sound plausible?

Use this tie-break order:

  1. Which answer matches the problem class most directly?
  2. Which answer stays at the AI-900 fundamentals level instead of diving into implementation?
  3. Which answer solves the stated need without drifting into a neighboring workload?

On AI-900, the broader correct service family is often better than a lower-level technical answer.

What should I do in the last 72 hours?

  • reread the cheat sheet first
  • rerun the leaf-page quizzes where misses still feel random
  • use the glossary only to untangle blurred terms
  • re-check the live Microsoft Learn pages on resources for retirement and wording changes

What should I trust when sources disagree?

Use this order:

  1. current Microsoft certification page
  2. current Microsoft study guide
  3. current Microsoft retirement page
  4. this guide
  5. older blog posts, videos, and third-party summaries
