Microsoft Azure Fundamentals (AZ-900)

The Microsoft Azure Fundamentals (AZ-900) certification is Microsoft's entry-level cert for the Azure cloud. It is the right starting point for anyone joining an Azure team — whether technical or not — and is a prerequisite-style stepping stone before role-based certifications like Azure Administrator (AZ-104), Azure Developer (AZ-204), and Azure Solutions Architect Expert (AZ-305).

This practice test gives you 250 real-style multiple-choice questions with detailed, multi-sentence explanations on every answer. Distribution mirrors the official Microsoft exam guide so the topic balance you study here matches what you'll actually see on test day.

What the AZ-900 exam covers

• Cloud Concepts (25–30%) — cloud benefits (high availability, scalability, reliability, predictability, security, governance, manageability), CapEx vs OpEx and consumption-based pricing, cloud service models (IaaS / PaaS / SaaS) and the Shared Responsibility Model, cloud deployment models (public / private / hybrid / multi-cloud), and disaster-recovery basics (Azure Site Recovery, Azure Backup, storage redundancy).
• Azure Architecture & Services (35–40%) — core architectural components (Regions, region pairs, Availability Zones, datacenters, subscriptions, resource groups, management groups, Azure Resource Manager); compute (Virtual Machines, VM Scale Sets, App Service, Functions, ACI / Container Apps, AKS, Azure Virtual Desktop); networking (VNets, NSGs, peering, VPN Gateway, ExpressRoute, Azure DNS, Front Door, Application Gateway, Load Balancer, Traffic Manager); storage (Blob, Files, Queue, Table; LRS / ZRS / GRS / GZRS redundancy); databases (Azure SQL Database, Azure SQL Managed Instance, Azure Database for PostgreSQL / MySQL / MariaDB, Cosmos DB, Synapse); identity and security (Microsoft Entra ID, MFA, Conditional Access, RBAC, Privileged Identity Management).
• Management & Governance (30–35%) — cost management (Pricing Calculator, TCO Calculator, Microsoft Cost Management, Budgets, Azure Reservations, Azure Hybrid Benefit, Spot VMs); governance (Azure Policy, Resource Locks, tags, management groups, Microsoft Purview); deployment and tools (Azure portal, Cloud Shell, Azure CLI / PowerShell Az, ARM, Bicep, Azure DevOps, GitHub Actions); monitoring (Azure Monitor, Log Analytics, Application Insights, Azure Advisor, Azure Service Health); and security tooling (Microsoft Defender for Cloud, Microsoft Sentinel, Azure Key Vault).

Exam format on Microsoft

The live AZ-900 has 40–60 questions to be completed within roughly 65 minutes of seat time (85 minutes total including instructions). The passing score is 700/1000 (~70%). Our 250-question bank covers the same syllabus in much greater depth so you build conceptual familiarity that goes beyond the exam itself.

Who should take this?

Microsoft positions AZ-900 as foundational — appropriate for non-technical roles (sales, marketing, project managers) as well as engineers new to Azure. Working professionals from on-premises or other cloud backgrounds use it as a structured way to cover the Azure-specific terminology and architecture before progressing to deeper certs.
