AZ-900 Overview — Format, What’s Tested & How to Prepare

Everything to know before taking Microsoft Azure Fundamentals (AZ-900): format and scoring, who it’s for, skills measured by domain, and a compact study plan mapped to our syllabus and practice.

Exam snapshot

  • Certification: Microsoft Azure Fundamentals (AZ-900)
  • Audience: Students, beginners, business/technical stakeholders, career-switchers
  • Experience target: 0–6 months with cloud/Azure concepts; light labs recommended
  • Format: Multiple choice/response, short concept items, matching/drag-and-drop
  • Timing: ~60–90 minutes appointment (varies by form)
  • Passing: Scaled score 700 (0–1000)

What AZ-900 measures (by domain)

1) Cloud concepts

  • IaaS vs PaaS vs SaaS; CapEx vs OpEx; elasticity, scalability, availability
  • Shared responsibility model; reliability vs fault tolerance vs disaster recovery

2) Azure architecture & core services

  • Global infrastructure: regions, availability zones, region pairs
  • Compute (VMs, App Service, Functions, containers), storage (Blob/Files/Disks), networking (VNet, VPN, ExpressRoute, Load Balancer)
  • Data services at a fundamentals level (Azure SQL, Cosmos DB)

3) Security, identity & governance

  • Microsoft Entra ID (Azure AD) basics; authentication vs authorization; RBAC
  • Defender for Cloud, Key Vault, Network Security Groups, Private Endpoints
  • Governance: management groups, subscriptions, resource groups, tags, Azure Policy

4) Cost management & SLAs

  • Pricing calculator, TCO basics, budgets & alerts
  • Service-level agreements and how redundancy affects availability

Who should take AZ-900?

  • New to cloud or Azure and want a recognized foundation
  • Non-engineering stakeholders who need to speak Azure fluently
  • Engineers planning a role path (e.g., AZ-104, AZ-204, AZ-305) and wanting a fast on-ramp

Readiness checklist

  • I can explain IaaS/PaaS/SaaS and pick the right model for a scenario.
  • I know regions vs availability zones vs region pairs.
  • I can choose a fit-for-purpose service (e.g., App Service vs VM).
  • I understand RBAC vs Policy vs Locks at a conceptual level.
  • I can estimate cost with the pricing calculator and interpret an SLA.

Compact 1–2 week plan

Days 1–2: Cloud concepts + shared responsibility + global infrastructure.
Days 3–5: Core services by category (compute, storage, networking, data).
Days 6–7: Identity/security/governance + cost/SLA.
Final days: Cheatsheet + Practice — two mixed sets and one full mock.


Exam-day tactics

  • First pass fast; flag longer scenario items for review.
  • Prefer managed, secure-by-default answers (least privilege, private endpoints where appropriate).
  • If two answers seem right, choose the one that is simpler, resilient, and operationally sound.
  • Watch for intent words: cost, resiliency, security, global reach, management overhead.
