How to prepare for the AZ-900 Azure Fundamentals exam

Know what the exam actually covers

AZ-900 tests three areas, and Microsoft publishes the skills outline for each: cloud concepts (what cloud computing is, the shared responsibility model, service models like IaaS, PaaS and SaaS, and the benefits of cloud — scalability, elasticity, reliability); Azure architecture and services (how Azure is organised into regions and availability zones, and the core compute, networking and storage services); and Azure management and governance (cost management, tools for deploying and managing resources, and governance and compliance features). The official skills outline on Microsoft Learn is your syllabus — read it before anything else and let it shape your study plan.

The framing matters as much as the topic list. AZ-900 is a fundamentals exam: it asks “which service would you use for this?” and “what does this concept mean?”, not “configure this correctly”. You are being tested on recognition and appropriate application — knowing that a service exists, what problem it solves and when it is the right choice — rather than on operating it. Study accordingly: breadth over depth, and always tie each service to the situation it fits.

Build your study around Microsoft Learn — it is free and official

Microsoft Learn’s AZ-900 learning path is the backbone of a sensible preparation plan. It is free, written by Microsoft, mapped directly to the skills outline, and broken into short modules with knowledge checks — which suits fundamentals-level study, where the goal is steady exposure to a wide set of concepts rather than deep dives. Work through the path in order, and treat the built-in knowledge checks as retrieval practice rather than a formality: answering from memory is what makes the material stick.

Supplement the reading with a free Azure account so the services stop being abstract names. You do not need to build anything serious — creating a resource group, browsing the portal, spinning up and deleting a small resource, and looking at the cost-management screens is enough to anchor the vocabulary in something you have actually seen. Azure offers a free account with starter credit for exactly this kind of exploration; check Azure’s site for the current terms. Ten minutes of clicking around after each study session does more for recall than an extra hour of reading.

Learn the service names — and what each one is for

A large share of AZ-900 difficulty is simply vocabulary. Azure has its own names for everything, and the exam expects you to match a described need to the right service. Build a running list as you study and rehearse it as “name → one-line purpose → when you would choose it”:

• Compute: virtual machines for full control, App Service for hosting web apps without managing servers, Azure Functions for event-driven code, containers for packaged workloads.
• Storage and databases: the main storage types and when blob, file or disk storage applies, plus Azure’s managed database options and what distinguishes them.
• Networking: virtual networks, how resources connect privately, and the services that manage traffic in and out.
• Identity: Microsoft Entra ID — the current name for what was Azure Active Directory — and its role in sign-in and access control.
• Governance and cost: management groups, subscriptions and resource groups as the organising hierarchy, plus policy, cost-management and compliance tooling.

Where candidates actually lose marks

Three traps recur. The first is assuming general cloud knowledge is enough — candidates with AWS experience, or a general sense of “what the cloud is”, often underestimate how Azure-specific the exam is. The concepts transfer, but the names, the resource hierarchy and Azure’s particular way of organising governance do not, and the questions are written in Azure’s vocabulary. If you have used another cloud, budget real time for translation, not just revision.

The second trap is skimming the governance, pricing and service-level agreement material because it feels less interesting than the services. Management and governance is a full exam area, and its concepts — how costs are managed, how policy is applied, what an SLA promises — are exactly the kind of thing that feels obvious while reading and turns slippery under exam wording. The third is confusing adjacent concepts: scalability versus elasticity, availability versus durability, the service models. Practice questions expose all three traps early, which is precisely why they belong in your plan and not just at the end of it.

A realistic timeline for a beginner

AZ-900 is foundational, so the honest expectation is weeks of casual study rather than months of intensive work — but resist anyone who gives you a precise number of days, because your starting point dominates. Someone already working in IT may move through the material quickly; someone entirely new to cloud computing should expect to take longer, and that is fine. Short, near-daily sessions beat weekend binges at this level especially, because the exam is broad recall and spaced repetition is how broad recall is built.

Let readiness, not the calendar, decide when you book. Work through the full learning path, then use practice questions and full-length mock exams to find your gaps — when you are consistently scoring comfortably above the pass mark across different question sets, and the explanations for your wrong answers have stopped surprising you, you are ready. One good mock is luck; a pattern is evidence.

Exam mechanics — and the non-expiry bonus

The exam is delivered by Pearson VUE, either online from home or at a test centre, and you book it through the exam page on Microsoft Learn. The passing score is 700 out of 1000 — Microsoft’s standard scaled pass mark — and the format can include several question styles beyond plain multiple choice, such as multiple response and drag-and-drop, so do not be thrown by an unfamiliar interaction on the day. Exam pricing varies by country and region, so check the official AZ-900 exam page on Microsoft Learn for the current fee where you live rather than trusting any figure you read elsewhere.

One genuinely pleasant detail: AZ-900, like Microsoft’s other Fundamentals certifications, does not expire. Unlike Azure’s role-based certifications — which are valid for a year and renewed through a free online assessment — a Fundamentals badge is yours permanently once earned. That makes AZ-900 a low-risk, lasting first credential, and a natural stepping stone towards a role-based certification such as AZ-104 Azure Administrator when you are ready to go deeper.
