AZ-900 Study Guide 2026: Domain-by-Domain Prep

AZ-900 Study Guide 2026 — Domain-by-Domain Prep Plan

The AZ-900 Microsoft Azure Fundamentals exam is the entry-level certification for cloud professionals looking to validate their understanding of Azure services. Covering three core domains — Cloud Concepts, Azure Architecture, and Management and Governance — the exam is ideal for both technical and non-technical candidates. This study guide breaks down every domain, provides a structured 4-week prep plan, and shows you exactly what to focus on to score 700 or higher on exam day.

How to Use This Study Guide

The AZ-900 Microsoft Azure Fundamentals exam is Microsoft's entry-level cloud certification. It tests conceptual knowledge — not hands-on engineering skills — making it ideal for beginners, business decision-makers, and IT professionals pivoting to cloud.

This guide is designed to be used as a complete prep roadmap, not just a reference sheet. Work through each section in order: understand the domain weights, allocate your time accordingly, then follow the 4-week plan day by day. If you are short on time, jump straight to the 4-Week Study Plan section and use the domain breakdowns as reference while you study.

The passing score for AZ-900 is 700 out of 1000. The exam contains 40–60 questions, mostly multiple-choice, with some drag-and-drop and scenario-based formats. You have 65 minutes to complete it.

Exam Domains Overview

Microsoft publishes an official skills outline for AZ-900. As of 2026–2026, the exam covers three domains with the following approximate weightings:

Domain 1 — Cloud Concepts: 25–30%
Domain 2 — Azure Architecture and Services: 35–40%
Domain 3 — Azure Management and Governance: 30–35%

Domain 2 carries the most weight, so allocate proportionally more study time there. Domain 3 is commonly underestimated — many candidates overlook cost management and compliance topics and lose easy points.

For additional context on how this exam fits into Azure certifications, see the AZ-900 complete guide and the Microsoft Certified Azure overview.

The Three AZ-900 Exam Domains

cloud Domain 1 — Cloud Concepts

Covers the fundamentals of cloud computing: what the cloud is, why organizations adopt it, and how it works. Key sub-topics include the shared responsibility model, cloud service types (IaaS, PaaS, SaaS), consumption-based pricing, and cloud deployment models (public, private, hybrid). This domain is conceptual — no Azure-specific technical depth required.

server Domain 2 — Azure Architecture & Services

The heaviest domain. Covers Azure's global infrastructure (regions, availability zones, region pairs), core services across compute (VMs, App Service, Azure Kubernetes Service), networking (VNet, VPN Gateway, ExpressRoute), storage (Blob, Disk, File, Queue), identity (Azure AD / Microsoft Entra ID), and security services (Defender for Cloud, Key Vault, Sentinel). Expect scenario-based questions asking which service fits a given use case.

shield Domain 3 — Management & Governance

Often underestimated. Covers cost management (Azure Pricing Calculator, TCO Calculator, Cost Management), governance tools (Azure Policy, Blueprints, Purview), resource management (Azure Resource Manager, management groups, subscriptions, resource groups), monitoring (Azure Monitor, Log Analytics, Azure Advisor, Service Health), and compliance features (Trust Center, compliance documentation).

4-Week AZ-900 Study Plan

This plan assumes roughly 1–1.5 hours of study per day. If you can dedicate more time, compress it into 2–3 weeks. Each week targets one domain, with the final week reserved for mixed review and practice exams.

Week 1 — Cloud Concepts (Domain 1)

Day 1: What is cloud computing? Benefits: high availability, scalability, elasticity, agility, disaster recovery. CapEx vs OpEx models.
Day 2: Shared responsibility model — what Microsoft manages vs what you manage across IaaS, PaaS, SaaS. Draw the responsibility matrix.
Day 3: Cloud service types in depth — IaaS (VMs), PaaS (App Service, SQL), SaaS (Microsoft 365). Real-world examples for each.
Day 4: Deployment models — public cloud, private cloud, hybrid cloud, multi-cloud. Trade-offs and use cases.
Day 5: Consumption-based pricing model. How Azure charges (per second, per GB, per transaction). Compare to on-premises fixed costs.
Day 6–7: Microsoft Learn — complete the Cloud Concepts learning path module. Take the knowledge check at the end.

Week 2 — Azure Architecture & Services (Domain 2)

Day 1: Azure global infrastructure: geographies, regions, availability zones, region pairs, sovereign regions. Know why AZs exist and how they protect workloads.
Day 2: Azure compute services: Virtual Machines, scale sets, Azure Virtual Desktop, containers (Azure Container Instances, AKS), Azure Functions, App Service. Know the use case for each.
Day 3: Azure networking: Virtual Networks, subnets, peering, VPN Gateway, Azure ExpressRoute, Azure DNS, Azure Content Delivery Network, DDoS Protection.
Day 4: Azure storage: storage account types, Blob storage (tiers: Hot/Cool/Archive), Azure Files, Azure Queues, Azure Disks, storage redundancy options (LRS, ZRS, GRS, GZRS).
Day 5: Identity & access: Microsoft Entra ID (formerly Azure AD), authentication vs authorization, MFA, Conditional Access, Azure RBAC, Zero Trust model, Passwordless.
Day 6: Azure security services: Microsoft Defender for Cloud, Azure Key Vault, Microsoft Sentinel, Azure Firewall, Web Application Firewall.
Day 7: Mixed review — quiz yourself on which service fits 10 real scenarios (pick from AZ-900 practice test questions with video answers).

Week 3 — Management & Governance (Domain 3)

Day 1: Cost management tools: Azure Pricing Calculator, Total Cost of Ownership (TCO) Calculator, Microsoft Cost Management + Billing. Practice estimating a VM cost.
Day 2: Azure resource hierarchy: Management Groups → Subscriptions → Resource Groups → Resources. How policies and RBAC inherit down the hierarchy.
Day 3: Azure Policy and Blueprints. How policies enforce compliance. Difference between initiative (policy set) and individual policy definition.
Day 4: Azure Advisor, Azure Service Health, Azure Monitor, Log Analytics Workspace. What each tool surfaces and when to use it.
Day 5: Azure Arc, Azure Resource Manager (ARM) templates, and infrastructure-as-code basics. Bicep vs ARM templates — understand the concept, not syntax.
Day 6: Compliance and trust: Microsoft Trust Center, Azure compliance documentation, privacy statements, Purview compliance manager.
Day 7: Full Domain 3 review. Work through 20 governance-focused practice questions from AZ-900 practice test exam.

Week 4 — Mixed Review & Practice Exams

Day 1–2: Full mixed practice exam (60 questions, timed at 65 minutes). Score yourself. Review every wrong answer — read the official Microsoft Learn explanation for each concept.
Day 3: Focus revision on your two weakest sub-topics. If you missed governance questions, re-read Day 1–3 of Week 3. If storage tripped you up, revisit Week 2 Day 4.
Day 4: Second full practice exam. Target 80%+ before booking the real exam. For extra drilling, use how to pass the AZ-900 exam strategies.
Day 5: Review the official AZ-900 exam skills outline PDF from Microsoft. Tick off every bullet point you feel confident about. Flag gaps.
Day 6: Light review only. No new material. Re-read your notes on the shared responsibility model, storage redundancy tiers, and resource hierarchy — these are high-frequency topics.
Day 7: Rest or a final 20-question warm-up the morning of your exam. You are ready.

How long does it take to study for AZ-900?

Most candidates need 2–4 weeks of consistent study (1–1.5 hours per day). Complete beginners with no cloud background may need 4–6 weeks. IT professionals already familiar with networking or server concepts often pass in 2 weeks. The 4-week plan in this guide is designed for the average candidate with no prior Azure experience.

Is AZ-900 hard to pass?

AZ-900 is considered an entry-level exam and is one of the more accessible Microsoft certifications. However, it is not a memorization test — Microsoft's scenario-based questions require genuine understanding of concepts like the shared responsibility model, storage tiers, and governance tools. Candidates who study from practice questions alone without understanding the underlying concepts often fail. The passing score is 700/1000.

What is the best free resource for AZ-900?

The Microsoft Learn Azure Fundamentals learning path (learn.microsoft.com) is the single best free resource. It covers all three domains with hands-on sandboxes, readings, and knowledge checks. It takes 10–12 hours to complete and is maintained by Microsoft to match current exam objectives. Supplement it with full-length timed practice exams to build exam-day stamina.

Which AZ-900 domain should I study most?

Domain 2 — Azure Architecture and Services — carries the most weight at 35–40% and has the most sub-topics (compute, networking, storage, identity, security). Allocate at least 40% of your total study time to it. Domain 3 — Management and Governance — is commonly underestimated at 30–35%; many candidates neglect cost management and compliance topics and lose easy points.

Can I pass AZ-900 without hands-on Azure experience?

Yes. AZ-900 tests conceptual and definitional knowledge, not hands-on implementation skills. You do not need to build anything in Azure to pass. That said, using the free Microsoft Learn interactive sandboxes to see services in action (creating a storage account, browsing the Azure Portal) significantly reinforces conceptual understanding and helps questions click faster during the exam.

How can I get a free AZ-900 exam voucher?

Microsoft offers free exam vouchers through its Virtual Training Day program. Attending both days of a free online AZ-900 Virtual Training Day event qualifies you for one free exam attempt. Availability varies by region and date. Check microsoft.com/en-us/trainingdays for upcoming sessions. Some Microsoft partners (including universities and corporate training programs) also offer sponsored vouchers.
