AZ-900 Study Guide 2026
Prepare for Microsoft Azure Fundamentals with a simple 2026 guide to cloud concepts, Azure services, governance, pricing, and support.
Published June 17, 2026
AZ-900 in Plain English
AZ-900 is designed for people who need a broad understanding of Azure rather than deep administration skills. You should know the difference between IaaS, PaaS, and SaaS, recognize common Azure services, and understand governance, identity, pricing, and support concepts.
The exam is friendlier than role-based Azure exams, but it still expects precision. For example, Azure Policy, role-based access control, Microsoft Entra ID, and management groups all relate to control, but they solve different problems.
Topics to Review
Study cloud concepts first, then Azure architecture, then management and governance. Build a mental map of where each service fits.
- Regions, availability zones, subscriptions, resource groups, and management groups
- Virtual machines, App Service, Functions, containers, and storage accounts
- Microsoft Entra ID, RBAC, conditional access concepts, and Defender for Cloud
- Azure Monitor, Advisor, Service Health, pricing calculator, and cost management
Practice Strategy
AZ-900 practice should emphasize vocabulary and service fit. If two answers sound similar, write down the difference after the session. Those small distinctions are often where points are won.
What to Learn Before Services
AZ-900 is easier if you understand cloud operating models before service names. Make sure you can explain public, private, and hybrid cloud, plus IaaS, PaaS, SaaS, scalability, elasticity, high availability, disaster recovery, and consumption-based pricing.
Once those ideas are clear, Azure service names become less random. Virtual Machines fit IaaS. App Service and Azure SQL Database fit managed platform use cases. Azure Functions supports event-driven workloads. Storage accounts provide different data services for blobs, files, queues, and tables.
- Cloud concepts: high availability, scalability, elasticity, agility, fault tolerance, and disaster recovery
- Azure architecture: regions, availability zones, subscriptions, resource groups, and management groups
- Core services: compute, networking, storage, databases, containers, and serverless
- Governance: Azure Policy, RBAC, tags, locks, Cost Management, Azure Advisor, and Microsoft Defender for Cloud
A Simple Two-Week AZ-900 Plan
AZ-900 can be prepared quickly if you already have IT experience, but do not rush vocabulary. Day one to three should cover cloud models and Azure architecture. Day four to seven should cover core services. Day eight to eleven should cover identity, security, governance, and cost. Use the final days for mixed practice.
If you are completely new to cloud, stretch this to four weeks. The goal is not to memorize a page of terms. The goal is to know which Azure concept solves which business problem.
- Write one sentence for every Azure service you study
- Compare RBAC, Microsoft Entra ID, Azure Policy, and management groups
- Practice pricing and support questions because they are easy points when studied properly
- Use Microsoft Learn sandbox-style material to see the portal flow before exam day
Common AZ-900 Mistakes
A common mistake is mixing identity and governance. Microsoft Entra ID handles identity and authentication. RBAC controls what a user, group, or service principal can do to Azure resources. Azure Policy enforces rules about resource configuration. Management groups organize subscriptions for governance at scale.
Another mistake is treating all monitoring tools as the same. Azure Monitor collects and analyzes telemetry, Service Health communicates Azure service issues, and Advisor recommends improvements for reliability, security, performance, cost, and operations.
Official Resources
Microsoft Learn is the best place to verify the current AZ-900 scope, duration, assessed skills, and study guide updates. Use it before your final practice pass.
