If you're looking for AZ-900 study materials, you're in the right place — but let's be honest about what actually works. Microsoft's Azure Fundamentals exam covers a lot of conceptual ground, and the market is flooded with prep content of wildly varying quality. Some of it is genuinely useful. A lot of it is surface-level material that'll let you pass the exam without actually understanding the concepts — which defeats the purpose if you're building a career in cloud.
This guide covers the best free and paid AZ-900 study resources, how the exam is structured, which domains to prioritize, and a realistic study schedule. By the end, you'll know exactly what to study and in what order.
You don't need to spend anything to pass AZ-900. Microsoft publishes genuinely comprehensive free study materials, and the quality is better than most paid alternatives.
Microsoft Learn's AZ-900 learning path is the authoritative free resource. It covers all three exam domains with interactive modules, hands-on sandboxes, and knowledge checks after each section. Go to learn.microsoft.com and search for AZ-900. The total learning path takes roughly 10-12 hours if you go at a reasonable pace.
What makes Microsoft Learn superior to most third-party resources is accuracy — it's maintained by the same team that writes the exam, and it reflects the current exam objectives. When third-party materials conflict with Microsoft Learn content, Microsoft Learn is right.
Microsoft offers a free practice assessment with 50 questions at learn.microsoft.com. It's not a full practice exam — it's shorter and the difficulty is calibrated to be slightly easier than the real exam — but it's valuable for identifying your weakest topic areas before you start intensive prep.
Microsoft publishes a downloadable AZ-900 study guide PDF that lists the specific skills and concepts measured on the exam. This is your definitive study checklist. Download it, read through every line, and check off what you know vs. what you need to learn. Don't start studying without it — you'll waste time on topics that aren't on the exam.
This is the most conceptual section of the exam and the one where people make the most careless errors. The questions aren't difficult if you understand the definitions, but many candidates memorize surface definitions without truly understanding the distinctions.
Key concepts you must know cold:
The AZ-900 Core Cloud Computing Concepts practice test is excellent for drilling these distinctions in a scenario-based format.
This is the largest domain and covers the most material. The focus areas within this domain are:
Azure Core Architecture: Regions, region pairs, availability zones, and how they support high availability. Azure geographies. The hierarchy: management groups, subscriptions, resource groups, resources — and what each layer is for. The AZ-900 Azure Core Architectural Components practice test targets this specific area.
Compute and Networking: Virtual machines (when to use them, scale sets, availability sets), Azure App Service, Azure Container Instances vs. Azure Kubernetes Service at a conceptual level, Azure Functions. Virtual networks, subnets, VPN gateways, ExpressRoute, Azure DNS, Content Delivery Network. The AZ-900 Compute and Networking practice test covers this domain.
Storage: Blob, disk, file, queue, table — what each is for and when you'd use it. Redundancy options: LRS, ZRS, GRS, GZRS — what each provides and the tradeoffs. Access tiers: hot, cool, archive. The AZ-900 Azure Storage Services practice test focuses here.
Identity and Security: Microsoft Entra ID (formerly Azure Active Directory), authentication vs. authorization, Conditional Access, Multifactor Authentication, Defender for Cloud, key vaults. The AZ-900 Identity and Security practice test is essential for this area — security questions appear throughout the exam, not just in the identity section.
This domain is where many candidates underinvest. Cost management, tags, Azure Policy, and RBAC questions are common — and they require understanding not just what these tools do, but how they interact.
Key areas: Cost Management and Billing (cost factors, TCO calculator, Azure Pricing calculator, cost reduction strategies). Azure governance tools: management groups, Azure Policy, Azure Blueprints, resource locks. Compliance: Microsoft Purview, Service Trust Portal, compliance standards. Monitoring: Azure Monitor, Azure Advisor, Azure Service Health. The AZ-900 Cost Management and Governance practice test covers this entire domain.
If you prefer video instruction over reading, a structured paid course can help. The most consistently well-reviewed options:
Scott Duffy's AZ-900 course on Udemy is frequently cited as the best value — comprehensive, regularly updated, and usually available for $15-20 during Udemy sales. It's about 6 hours of video instruction and includes practice questions.
A Cloud Guru (now Pluralsight): Good production quality and interactive labs. More expensive than Udemy, but the hands-on labs are genuinely useful for building mental models of Azure services.
Whizlabs: Strong practice question bank — 500+ AZ-900 practice questions. If you want volume beyond what free resources provide, Whizlabs is a cost-effective option.
For the AZ-900 specifically, paid courses aren't necessary if you're disciplined about working through Microsoft Learn. The exam is entry-level — it doesn't require hands-on Azure experience, and the conceptual material is well-covered by free resources. Paid courses add value primarily for people who learn better through video and want a single structured resource rather than multiple free sources.
For practice test volume, the AZ-900 practice tests page gives you free access to questions across all three domains. Work through several rounds before exam day. And if you want a comprehensive overview of everything the exam covers, the AZ-900 certification guide breaks down every topic area with study guidance.
The week before shouldn't involve learning anything new. If you're still trying to understand new concepts a week out, you're underprepared — push your exam date back. The final week is for consolidation: working through practice questions to confirm your understanding holds up under exam pressure, and identifying the handful of areas where you're still shaky.
Take a full timed practice exam 2-3 days before your actual exam. Score yourself. Review every wrong answer. On exam day, you want your weakest areas to be ones you consciously reviewed, not ones you just hope won't come up.
