AZ-900 Study Guide: How to Pass Azure Fundamentals

Studying for the AZ-900? Here's the short version. Azure Fundamentals is a beginner exam with no prerequisites, you pass at 700 out of 1000, and most people get ready in two to three weeks of light study. There are usually somewhere around 35 to 50 questions and roughly 45 minutes to answer them, though the exact count varies by exam form. The rest of this guide walks through what to study and how.

The AZ-900 is the entry point to Microsoft's Azure certifications. It's designed for people who are new to the cloud, including non-technical folks in sales, project management, or finance roles who just need to understand what Azure does. If that's you, don't be intimidated. This exam tests concepts and vocabulary, not hands-on engineering.

What's on the AZ-900 exam?

Microsoft splits the exam into three skill areas, each weighted differently. Knowing the weights tells you where your time goes.

• Cloud concepts (25 to 30%): what the cloud is, the benefits of cloud computing, and the differences between IaaS, PaaS, and SaaS, plus public, private, and hybrid models.
• Azure architecture and services (35 to 40%): the core building blocks. Regions and availability zones, resource groups, compute options like virtual machines and App Service, storage, networking, and database services.
• Azure management and governance (30 to 35%): cost tools like the pricing calculator and Cost Management, plus governance and compliance features like tags, Azure Policy, role-based access control, and the Trust Center.

The middle area is the biggest, so spend the most time on Azure's actual services. The other two are lighter but full of easy points if you learn the terminology.

What's the AZ-900 passing score?

You need 700 out of 1000 to pass. That's a scaled score, not a straight percentage, so it doesn't mean you got exactly 70% of questions right. Microsoft weights questions differently and scales the result.

There's no penalty for a wrong answer, so never leave anything blank. If you're stuck, eliminate what you can and pick the best remaining option. A guess can score, a blank never will.

How much does the AZ-900 cost?

The exam is about 99 USD in most regions, though the price shifts a bit by country and currency. Students and some other groups may qualify for discounts through Microsoft, so it's worth checking before you book.

How long does it take to study for the AZ-900?

For most people, two to three weeks at about an hour a day is plenty. If you already work in tech or use any cloud platform, you might be ready in a week. If cloud computing is brand new to you, give yourself a month and don't rush it.

Here's a simple plan:

1. Days 1 to 4: Cloud concepts. Learn the vocabulary first. IaaS vs. PaaS vs. SaaS, public vs. private vs. hybrid, and why companies move to the cloud (scalability, pay-as-you-go, reliability). This is the foundation everything else sits on.
2. Days 5 to 12: Azure services. The biggest area, so spend the most days here. Cover regions, availability zones, resource groups, virtual machines, App Service, Azure Storage, virtual networks, and the main database options. Focus on what each service is for, not deep configuration.
3. Days 13 to 16: Management and governance. Cost Management, the pricing and TCO calculators, Azure Policy, role-based access control, tags, and compliance basics.
4. Days 17 to 21: Practice questions. Switch to timed practice and review every answer. This is where your score climbs the fastest.

Don't try to memorize every Azure service. There are hundreds, and the exam only touches a few dozen at a fundamentals level. Understanding the common ones beats half-remembering all of them.

How hard is the AZ-900?

It's one of the more approachable certifications out there. The questions test recognition and understanding, not problem-solving under pressure. You'll see definitions, "which service fits this need" matchups, and a few true/false style statements.

The trap isn't difficulty, it's vagueness. Some questions describe a need and ask which Azure service or feature matches. If you only memorized names without understanding what each thing does, those questions get slippery. So study for meaning. Be able to say in one plain sentence what Azure Policy does, or when you'd pick App Service over a virtual machine.

What's the best way to study for Azure Fundamentals?

Reading docs teaches you definitions. Practice questions teach you how Microsoft phrases things and how they expect you to choose, which is what actually gets tested. So don't wait until the end to start answering questions. Begin earlier than feels comfortable.

For each question, focus on the reasoning, not just the right letter. Ask why the correct option beats the others, and do this even for questions you got right, because guessing correctly and understanding are not the same thing.

A few habits that help:

• Do a couple of timed sets near the end so 45 minutes feels normal on exam day.
• Keep a short list of things you keep mixing up (IaaS vs. PaaS, resource group vs. subscription, Azure Policy vs. role-based access control) and drill those.
• Read the explanation for every option, not only the one you picked.

You can practice with real exam-style questions for Azure Fundamentals, and each one comes with a full explanation of why every option is right or wrong. That explanation is the part that moves your score.

What should I do the day before?

Stop learning new material. The last day is for review, not cramming. Skim your weak-spot list, do one short practice set, and then leave it alone.

Sort the logistics too. Decide whether you're testing at a center or online with remote proctoring, and if it's online, check your room and webcam setup ahead of time. A good night's sleep does more for your score than one more hour of notes.
