AZ-900 Study Guide: Pass Microsoft Azure Fundamentals

The AZ-900 study guide you actually need isn't a 300-page textbook. It's a clear map of what the exam covers, what the most common question types look like, and how to structure your study time so you're not wasting hours on topics that barely show up.

AZ-900 — the Microsoft Azure Fundamentals exam — is the entry point to Microsoft's Azure certification path. It's designed for non-technical and technical candidates alike. You don't need to be a developer or engineer to pass it. But you do need to understand cloud concepts and the Azure service landscape well enough to answer scenario-based questions correctly.

This guide covers everything in the current exam outline: the six skill domains, what each one tests, how to prepare efficiently, and what resources to use.

What Is the AZ-900 Exam?

AZ-900 is a foundational Microsoft Azure certification exam. It tests your knowledge of cloud computing concepts and Microsoft's core Azure services, pricing, security, and governance. Passing it earns you the Microsoft Certified: Azure Fundamentals credential.

It's positioned as an entry-level exam — no prerequisites, no experience required. That said, "entry-level" doesn't mean trivial. The exam uses scenario-based questions that require you to understand why a service or concept applies in a given situation, not just what it is.

For more on what the full certification looks like, see our AZ-900 certification guide.

The Six AZ-900 Skill Domains

Microsoft publishes the exact exam outline at learn.microsoft.com. The content is organized into six domains, each with a specific weighting:

1. Cloud Concepts (25–30%)

This is the biggest domain and the one that trips up overconfident candidates. Don't skip it. You need to know:

• The definition of cloud computing and why organizations move to it (scalability, elasticity, high availability, agility, CapEx vs. OpEx)
• IaaS vs. PaaS vs. SaaS — and realistic examples of each
• Public cloud, private cloud, hybrid cloud, and multi-cloud
• Shared responsibility model — who's responsible for what at each service type
• Benefits of cloud: fault tolerance, disaster recovery, global reach, economies of scale

Questions often give you a scenario — "a company wants to avoid managing physical servers but needs custom OS configurations" — and ask which service type fits. Know the distinctions cold.

2. Azure Architecture and Services (35–40%)

This is the largest domain and the most detailed. It covers Azure's physical and organizational structure, plus core service categories:

Architecture basics: Azure regions, region pairs, availability zones, resource groups, subscriptions, and management groups. Know the hierarchy: Management group → Subscription → Resource group → Resource.

Compute: Virtual Machines, Azure App Service, Azure Container Instances, Azure Kubernetes Service, Azure Functions (serverless). Know when you'd use each.

Storage: Blob storage, Azure Files, Azure Disk Storage, Azure Queue Storage. Know the difference between hot, cool, and archive tiers.

Networking: Virtual Networks (VNet), VPN Gateway, Azure ExpressRoute, Azure DNS, Azure Content Delivery Network, Load Balancer, Application Gateway.

Databases: Azure SQL Database, Azure Cosmos DB, Azure Database for MySQL/PostgreSQL. Know which is relational vs. NoSQL and when to use each.

Identity: Azure Active Directory (now Entra ID) — authentication vs. authorization, single sign-on, multi-factor authentication, conditional access.

3. Azure Management and Governance (30–35%)

This domain covers how you manage Azure resources, control costs, and stay compliant:

Cost management: Azure Pricing Calculator, Total Cost of Ownership (TCO) Calculator, Azure Cost Management + Billing. Know the factors that affect Azure costs: resource type, consumption model, region, billing zone.

Governance tools: Azure Policy, Azure Blueprints, resource locks, tags. Know what each does and why you'd use it.

Monitoring: Azure Monitor, Azure Service Health, Azure Advisor. Understand what each monitors and the alert types available.

Management tools: Azure Portal, Azure CLI, Azure PowerShell, Azure Cloud Shell, Azure Resource Manager (ARM) templates.

Security: Microsoft Defender for Cloud, Azure Security Center, network security groups, Azure Firewall, DDoS Protection (Basic vs. Standard).

What the Exam Actually Asks

AZ-900 questions aren't about memorizing service names. They test whether you understand use cases. Here's the kind of reasoning the exam requires:

• "Which Azure service should a company use if they want to host a web app without managing the underlying OS?" → Azure App Service (PaaS), not a Virtual Machine (IaaS)
• "A startup needs to store unstructured data that rarely gets accessed but must be kept for compliance." → Azure Blob Storage with the archive tier
• "What ensures that an Azure VM continues running if a single datacenter goes down?" → Availability Zones, not just an Availability Set

The pattern: read the scenario, identify the key constraint (cost, availability, management overhead, compliance), then match to the right service or concept.

Free Study Resources

Microsoft provides excellent free prep material:

• Microsoft Learn AZ-900 path: Free, structured, directly aligned to the exam outline. Covers all six domains with interactive exercises. Takes 8–12 hours total.
• AZ-900 skills outline: Available at learn.microsoft.com — lists every sub-topic that might appear. Use it as a checklist.
• Azure free account: Create a free Azure account and explore the portal, spin up a VM, browse pricing. Hands-on exposure makes concepts stick.
• Microsoft Learn Sandbox: Some Learn modules include free sandboxed Azure environments — no subscription needed.

A Realistic 2-Week Study Plan

If you can spend 1–2 hours per day, here's how to structure 2 weeks:

Days 1–3 — Cloud Concepts: Complete the Cloud Concepts module on Microsoft Learn. Focus on the shared responsibility model, service types, and CapEx vs. OpEx. Do 25 practice questions on this domain.

Days 4–7 — Azure Architecture and Services: This is the meatiest section — give it the most time. Study the regional architecture, compute options, storage tiers, and networking services. Create a mental comparison table: IaaS vs. PaaS for each compute service. Do 50 practice questions.

Days 8–10 — Management and Governance: Study cost management tools, governance features (Policy, Blueprints, tags), and monitoring services. Do 40 practice questions.

Days 11–13 — Full Practice Exams: Take two complete timed practice exams. Review every wrong answer. Look up the Microsoft Learn page for each topic you miss. Target 80%+ before exam day.

Day 14 — Light Review: Go through the skills outline one more time. Note any remaining weak spots and read the Learn documentation for those topics. Sleep well before the exam.

Common Mistakes to Avoid

A few patterns show up among candidates who need a second attempt:

• Skipping Cloud Concepts because it sounds basic. It's 25–30% of the exam. CapEx vs. OpEx and the shared responsibility model show up constantly.
• Confusing availability zones and availability sets. These are different. Availability Zones protect against datacenter failure; Availability Sets protect against hardware failure within a datacenter.
• Mixing up Blob storage tiers. Hot = frequent access, Cool = infrequent, Archive = rarely accessed/compliance. Cost tradeoffs go the opposite direction.
• Not practicing scenario questions. Reading is passive. If you only read the Learn modules without doing practice questions, you'll struggle with the applied scenarios on exam day.

After AZ-900: What's Next?

AZ-900 is the foundation. After passing, the most common paths are:

• AZ-104: Azure Administrator Associate — managing Azure resources, identity, governance
• AZ-204: Azure Developer Associate — building and deploying Azure applications
• AI-900: Azure AI Fundamentals — if you want to understand Azure's machine learning and AI services
• SC-900: Security, Compliance, and Identity Fundamentals — good companion to AZ-900 if you're in IT or compliance

AZ-900 gives you the vocabulary and conceptual framework. Associate-level exams build the hands-on technical depth on top of it. Most candidates who take AZ-900 seriously — completing the full Learn path, doing substantial practice questions, exploring the Azure free tier — pass on their first attempt.
