Microsoft Azure Fundamentals (AZ-900) — Practice Questions and Mock Exam

The AZ-900 certification demonstrates foundational knowledge of cloud concepts and Azure services. It covers core cloud computing principles, Azure architecture components, Azure management and governance tools, compute, networking, storage services, identity, security, privacy, compliance, and Azure pricing and support. The exam validates a broad understanding of what Azure offers without requiring deep technical implementation skills.

This is the recommended entry point for anyone new to cloud computing or Azure, including business professionals, IT managers, sales and marketing teams, students, and non-technical stakeholders. It provides a solid foundation before pursuing role-based Azure certifications like AZ-104 or AI-200.

Azure architecture and services carries the most weight at 35–40%: regions and availability zones, compute and networking basics, storage services, and identity fundamentals like Microsoft Entra ID and RBAC. Management and governance follows close behind at 30–35%, covering cost management, Azure Policy, resource locks, and the portal, CLI, and ARM tooling used to manage resources. Cloud concepts (the shared responsibility model, service types, deployment models) sits at 25–30%, the conceptual base the other two domains build on.

The two heavier domains reward breadth across the Azure service catalog over depth in any one service, which is why the exam favors candidates who've explored the portal broadly rather than gone deep on a single workload.

AZ-900 draws 40–60 questions from a mix of multiple-choice, multiple-response, drag-and-drop, true/false, and dropdown-selection formats inside a 45-minute window. Questions test conceptual understanding rather than hands-on configuration — recognizing what a service does and when to use it, not how to deploy it.

Every domain of the AZ-900 exam has enough questions in the pool to practice it in depth. A mock exam asks 50 questions in one sitting, on the same 45-minute clock as the real thing.

How long you'll need depends on how much hands-on experience you bring. The rest is set by the vendor: how the exam is delivered, how soon you can retake it, and how long the credential stays valid.

AZ-900 runs through Pearson VUE, either online with a remote proctor or at an authorized testing center, and is offered in English, Japanese, Chinese, Korean, French, German, Spanish, Portuguese, and several other languages depending on location. As a Fundamentals certification, it does not expire and carries no renewal requirement.

IaaS, PaaS, and SaaS responsibility boundaries are tested directly — knowing which party manages what at each layer, and which Azure services fall into which category, catches more candidates than any single service question. Datacenter geography concepts get confused with each other despite governing different availability and compliance guarantees — availability zones, paired regions, and sovereign clouds each answer a different question. The Pricing Calculator and the Total Cost of Ownership Calculator solve different problems, and candidates often can't say which one a scenario calls for. Azure Policy, Blueprints, management groups, and resource locks each govern a different layer, and Microsoft Entra ID features (MFA, Conditional Access, SSO) get mixed up with on-premises Active Directory concepts they only superficially resemble.
