The AZ-900 Microsoft Azure Fundamentals exam is the entry point into Microsoft's cloud certification ecosystem. Whether you're an IT professional pivoting to cloud, a developer broadening your skills, or a business decision-maker wanting to understand Azure, this guide gives you a structured, no-fluff roadmap to pass the exam in 2026.
What the AZ-900 Exam Covers
Microsoft organises the AZ-900 objectives into five core domains. As of the 2026 syllabus update, the weightings are:
- Cloud Concepts — 25–30%
- Azure Architecture and Services — 35–40%
- Azure Management and Governance — 30–35%
You do not need hands-on development experience. The exam tests conceptual understanding, not scripting ability. That said, spending time in the Azure portal is invaluable for retaining abstract concepts.
Cloud Concepts: What You Must Know
This section trips up candidates who skip the basics. You need to clearly distinguish between:
- IaaS, PaaS, and SaaS — Know a real-world example of each (VMs = IaaS, App Service = PaaS, Microsoft 365 = SaaS).
- Public, Private, and Hybrid Cloud — Understand why an organisation might choose each model.
- CapEx vs OpEx — Cloud shifts spending from capital expenditure (buy servers) to operational expenditure (pay monthly). The exam loves this distinction.
- High Availability, Fault Tolerance, Scalability, Elasticity, and Agility — Learn the precise Microsoft definitions. "Elasticity" means automatically scaling up and down; "agility" means deploying resources quickly.
Azure Architecture and Services
This is the heaviest domain. Focus your study time here. Key areas:
Compute
- Azure Virtual Machines — IaaS, full OS control, you manage patching.
- Azure App Service — PaaS for web apps. No OS management required.
- Azure Functions — Serverless compute. You pay only when code runs.
- Azure Container Instances and AKS — Containerised workloads without and with orchestration.
Networking
- Azure Virtual Network (VNet) — Logical isolation of Azure resources.
- VPN Gateway — Encrypted site-to-site or point-to-site connections.
- Azure ExpressRoute — Private, dedicated connection from on-premises to Azure. Not over the public internet.
- Azure DNS and Azure Load Balancer — Know their purpose at a high level.
Storage
- Blob, File, Queue, and Table Storage — Know which is for which workload.
- Storage redundancy — LRS, ZRS, GRS, RA-GRS. LRS replicates within one data centre; GRS replicates to a paired region.
Azure Management and Governance
This domain has grown in recent exam sittings. You must understand:
- Azure Resource Manager (ARM) — The deployment and management layer for all Azure resources.
- Azure Policy — Enforce organisational rules. Example: "All VMs must use approved SKUs."
- Role-Based Access Control (RBAC) — Grant least-privilege access. Owner, Contributor, Reader are the built-in roles you must know.
- Microsoft Cost Management — Budgets, alerts, and cost analysis.
- Service Level Agreements (SLAs) — Azure guarantees uptime percentages. A 99.9% SLA allows ~8.7 hours downtime per year.
Effective Study Strategy
- Use Microsoft Learn — The official free learning path is comprehensive and maps directly to exam objectives. Complete the "Azure Fundamentals" path (AZ-900).
- Practice in the Azure Free Tier — Create a free account. Deploy a VM, create a storage account, explore the Cost Management blade. Hands-on memory beats flashcards.
- Take timed practice exams — Use MeasureUp or Whizlabs. Aim for 85%+ before booking your real exam. The pass mark is 700/1000.
- Review wrong answers immediately — Don't just note what you got wrong; read the explanation and trace it back to the official documentation.
- Watch John Savill's AZ-900 Study Cram on YouTube — A single, dense video that covers the whole syllabus in about 3 hours. Excellent for final revision.
Common Exam Pitfalls
Candidates who fail AZ-900 typically make these mistakes:
- Confusing availability zones (physically separate data centres within a region) with availability sets (logical groupings of VMs within a data centre).
- Mixing up Azure Advisor (recommendations) and Azure Monitor (telemetry and alerts).
- Not knowing that Azure Blueprints is deprecated in favour of Template Specs and Deployment Stacks — the exam may still reference it.
- Underestimating the governance section. Questions are scenario-based: "A company needs to ensure all resources are tagged with a cost-centre. What should they use?" Answer: Azure Policy.
Booking and Exam Day
The exam is 45 minutes, 40–60 questions, available online or at a Pearson VUE test centre. Online proctoring is convenient but requires a clean desk environment and stable internet. Budget 2–4 weeks of study for complete beginners; experienced IT professionals often pass in 1–2 weeks of focused prep.
You've got this. Start with Microsoft Learn today, build a free Azure account, and work through every objective domain methodically. The AZ-900 is achievable for anyone willing to put in the hours.
