Microsoft Azure Fundamentals
Who this exam is for
The Microsoft Azure Fundamentals certification is designed for professionals who work with or want to work with Microsoft technologies in a professional capacity. It is taken by cloud engineers, DevOps practitioners, IT administrators, and technical professionals looking to validate their expertise.
You do not need extensive prior experience to attempt it, but you will benefit from hands-on familiarity with the subject matter. The exam tests applied knowledge and architectural judgment, not just memorization. If you can reason about trade-offs and real-world scenarios, structured practice will handle the rest.
Domain breakdown
The AZ-900 exam is built around official domains, each with a fixed percentage of the question pool. This distribution should directly inform how you allocate your study time.
Note the domain with the highest weight — many candidates under-invest here because it feels conceptual. In practice, this is where the exam is most precise, with scenario-based questions that test specifics.
What the exam actually tests
This is not a memorization exam. Questions require applied judgment under constraints. Almost every question includes a scenario with explicit requirements and asks you to select the most appropriate solution.
Here are examples of the question types you will encounter:
