Microsoft Azure Fundamentals (AZ-900) is the entry-level credential for the Azure platform. It validates a candidate's ability to describe core cloud concepts, the major Azure architectural components, and Azure management and governance features. The audience is broad: business stakeholders, sales and pre-sales engineers, project managers, students, and engineers from other clouds who need an Azure literacy stamp. The exam is conceptual rather than hands-on — expect 40–60 questions in 45 minutes covering shared responsibility, cloud service models (IaaS/PaaS/SaaS), Azure regions and availability zones, core compute and storage services, Microsoft Entra, RBAC, and cost-management tooling.
Cloud benefits, capex vs. opex, IaaS / PaaS / SaaS, public / private / hybrid models, the shared responsibility model. Pure vocabulary domain — about 28% of questions.
Largest domain at 37%. Regions, availability zones, resource groups, subscriptions, management groups, and the headline services across compute (VMs, App Service, Functions, AKS, Container Instances), networking (VNets, peering, VPN, ExpressRoute), and storage (Blob, Files, Disks, Queues, Tables).
35% of the exam. Cost-management tools (TCO calculator, Pricing Calculator, Cost Management + Billing), Azure Policy, resource locks, Microsoft Purview, Service Health, Azure Advisor, and Azure Monitor / Log Analytics. Heavy on knowing which tool addresses which governance scenario.
$60k–$95k–$135k USD annual
AZ-900 alone rarely moves the needle on salary — it is a foundational signal, not a hiring requirement. Range reflects US-based roles where cloud literacy is expected. Engineers with hands-on Azure experience typically pair AZ-900 with AZ-104 or AZ-204, which lift compensation meaningfully.

AZ-900 is one of the highest-volume Microsoft certifications globally, partly because Microsoft frequently runs free voucher campaigns through Microsoft Learn challenges and partner programs. Recruiters treat it as a baseline literacy signal rather than a differentiator — useful on a resume for non-engineering roles (sales, project management, consulting) where a cloud vocabulary is increasingly assumed. Engineers commonly use AZ-900 as a stepping stone to AZ-104 or AZ-204; in that context it pairs naturally with the AI-900 or DP-900 fundamentals to round out a full Azure-platform overview.
There are no formal prerequisites. AZ-900 is designed to be the first Azure exam most candidates take, and Microsoft's official Microsoft Learn path requires no prior cloud experience. Plan on around 10–15 hours of free content on Microsoft Learn covering the three exam areas.
If you already hold AWS Cloud Practitioner or Google Cloud Digital Leader, expect to need only 5–10 hours to map equivalent vocabulary onto Azure-specific service names. Microsoft Learn Sandboxes provide a free hands-on environment that — while not strictly required — makes terminology stick faster. Microsoft regularly distributes free AZ-900 vouchers through "Get Certified" challenges, Microsoft Ignite registration, and partner training programs.
AZ-900 sits at the Fundamentals tier — the most approachable Microsoft exam. Plan on 15–25 hours of study over 2–3 weeks if you have no prior cloud exposure; experienced engineers often pass with 5–10 hours of focused review. The exam runs about 45 minutes with roughly 40–60 questions in mixed formats: multiple choice, multiple response, and drag-and-drop matching exercises. There are no case studies at the Fundamentals level.
The most common stumbling block is service-name overload — Azure has dozens of named services across compute, networking, storage, security, and governance, and the exam expects you to match each to its primary use case. Memorizing the management-and-governance toolset (Azure Policy vs. Blueprints vs. Resource Locks vs. Microsoft Purview) is where most candidates spend their final review hours.
Most recent skills-measured update. Refreshed AI/ML and Microsoft Entra (formerly Azure AD) terminology, added emphasis on Azure Arc and FinOps tooling. Microsoft refreshes the AZ-900 outline approximately yearly without changing the exam code.
Restructured the exam into three domains (down from six), repositioned Microsoft Entra and renamed several services in line with Microsoft's 2022 branding.
AZ-900 (Microsoft Azure Fundamentals) is a considered an entry-level exam testing breadth of conceptual understanding rather than hands-on depth Foundational-level exam. Most candidates need 30–80 hours of study spread over 3–6 weeks for foundational-level exams. Most candidates who score consistently above the passing threshold on practice exams pass on their first attempt.
