About the Azure AZ-900 exam
Exam at a glance
The broadest Azure foundational credential and Microsoft's most popular cloud entry-point exam. Microsoft Fundamentals certifications do not expire — no renewal assessment is required after you pass.
Who AZ-900 is for
AZ-900 is unusually broad in audience. It's an excellent fit for:
- Business analysts, sales, project managers, executives who need shared cloud vocabulary to participate in Azure conversations and decisions.
- IT generalists adding Azure knowledge alongside existing AWS, GCP, or on-prem experience.
- Career changers using the credential as a visible signal of cloud literacy on a CV or LinkedIn profile.
- Students exploring whether a cloud / Azure career path is the right fit before committing to deeper hands-on certifications.
Domain weighting
- Describe cloud concepts: 25–30%
- Describe Azure architecture and services: 35–40%
- Describe Azure management and governance: 30–35%
Why take this certification
- Most-taken Azure credential. AZ-900 is by a wide margin the most popular Azure certification. Microsoft has issued it to millions of professionals worldwide, making it a recognizable shorthand for "knows what Azure is and how it works at a conceptual level."
- No expiry, ever. Unlike the Associate and Expert tiers, Fundamentals certifications are permanent. Pass once and the credential stays valid for the rest of your career.
- Low entry cost. At $99 USD with no prerequisites, AZ-900 is one of the most affordable globally recognized cloud credentials available.
- Gateway to deeper Azure tracks. AZ-900 builds the vocabulary you'll need for hands-on credentials like AZ-104 Administrator and design-focused credentials like AZ-305 Solutions Architect Expert.
What you'll learn in the AZ-900 exam
AZ-900 is conceptual rather than hands-on. Microsoft expects you to describe services, trade-offs, and Azure's operating model — not configure them. Questions are short scenarios that test whether you can match a workload requirement to the appropriate Azure service or governance feature.
Cloud concept basics
- Service models: IaaS, PaaS, SaaS — what each abstracts and a typical example service for each.
- Deployment models: public, private, hybrid — and the situations each fits best.
- Shared responsibility model: what the customer owns vs what Microsoft owns at each service tier.
- Cloud economics: CapEx vs OpEx, elasticity, scalability, agility, fault tolerance, disaster recovery, high availability.
Azure architecture
- Global infrastructure: regions, region pairs, sovereign regions, availability zones, datacenters.
- Resource hierarchy: resource groups, subscriptions, management groups — and how RBAC scopes inherit through them.
Core compute services
- Virtual Machines — IaaS workloads, sizing families, availability sets vs availability zones.
- App Service — managed PaaS hosting for web apps and APIs.
- Container Instances and Azure Kubernetes Service (AKS) — single-container vs orchestrated container workloads.
- Azure Functions — serverless event-driven compute.
Core storage services
- Blob — unstructured object storage (hot / cool / archive tiers).
- Queue — decoupled message storage.
- Table — NoSQL key-value storage.
- File — managed SMB / NFS file shares.
- Disk — managed block storage attached to VMs.
Core networking services
- VNet — Azure's foundational network primitive: subnets, NSGs, peering.
- ExpressRoute and VPN Gateway — private and encrypted on-prem-to-Azure connectivity.
- Azure DNS, Load Balancer, Application Gateway, Azure Firewall — name resolution, layer-4 vs layer-7 distribution, and managed perimeter security.
Core identity
- Microsoft Entra ID (formerly Azure AD) — Azure's identity backbone, users, groups, sign-in, MFA.
- Conditional access at a concept level — policy-driven sign-in decisions.
Core governance and management
- Azure Policy — guardrails that enforce or audit resource configuration.
- Resource Locks — protection against accidental delete / modify.
- Role-Based Access Control (RBAC) — assigning identities to scoped roles.
- Cost Management — budgets, cost analysis, alerts.
- Azure Monitor and Service Health — observability, alerting, and platform incident visibility.
How to prepare for the AZ-900 exam
AZ-900 is one of the friendliest cloud exams to prepare for. Most candidates pass with 2–4 weeks of part-time study, even with no prior Azure experience. A practical approach:
- Complete the free Microsoft Learn AZ-900 learning path (1–2 weeks). Microsoft's official AZ-900 learning path is around 8–12 hours of guided modules and is the single best free resource. Work through every module — don't skip the cloud-concepts section even if it feels obvious.
- Get hands-on with a free Azure account (1 week). Sign up for the Azure free account for $200 in credit and 12 months of free services. Deploy a VM, create a storage account, set up a VNet, and explore the Azure portal — the hands-on click-around dramatically improves retention even though AZ-900 doesn't test configuration directly.
- Read Microsoft's official AZ-900 study guide PDF (a few hours). The official AZ-900 study guide lists every objective with exact wording — a perfect last-pass checklist before your attempt.
- Practice exams (1 week). Take timed practice tests to identify weak areas. Aim for consistent 80%+ scores before scheduling. Microsoft's own free practice assessment is the closest thing to the real exam format.
Recommended timeline
2–4 weeks for IT generalists. 4–6 weeks for complete beginners with no prior tech background. Most candidates spend 20–40 total hours preparing.
Frequently asked questions
Are these actual exam questions?
No. All Nex Arc Azure AZ-900 practice questions are original content based on the provider's published exam blueprint, official documentation, and real-world scenarios across every topic the exam covers. We do not offer brain dumps, leaked questions, or actual exam content. Using or distributing real exam questions violates certification provider agreements and can result in certification revocation.
How many questions are in the AZ-900 exam?
The AZ-900 exam typically contains 40-60 questions delivered in a 45-minute session. Microsoft does not publish an exact question count and it can vary slightly between attempts. Question types include multiple choice, drag-and-drop, hot-area, and case-study style items.
What's the AZ-900 passing score?
The passing score is 700 out of 1000. Microsoft uses a scaled scoring model where questions are weighted, so a raw 70% on the practice questions does not perfectly map to the scaled score. Focus on understanding the concepts behind every answer rather than memorizing.
How do I access the full AZ-900 practice exam?
Click on the Buy Now button in the sidebar to purchase the complete AZ-900 course. After payment, you'll have instant access to 12 practice exams with detailed explanations and lifetime access.
What are the prerequisites for the AZ-900 exam?
There are no formal prerequisites. AZ-900 is designed as Microsoft's entry-level cloud credential and is open to anyone — business analysts, sales engineers, project managers, executives, and IT generalists alike. Basic familiarity with general IT concepts (servers, networks, databases) is helpful but not required. Most candidates can prepare in 2-4 weeks of part-time study without any prior Azure experience.
Does the AZ-900 certification expire?
No. Microsoft Fundamentals certifications — including AZ-900, AI-900, DP-900, SC-900, and MS-900 — do not expire and require no renewal assessment. Once you pass AZ-900, the credential is permanent. This is different from Microsoft's Associate and Expert tier certifications (AZ-104, AZ-305, etc.), which require an annual free online renewal assessment to stay current.
What's the exam cost and can I retake it if I fail?
The AZ-900 exam costs $99 USD in most markets (converted to local currency, with some regional variation). It is delivered through Pearson VUE either at a testing center or via online proctoring. If you fail, Microsoft requires a 24-hour wait before your second attempt. From the third attempt onward the wait time grows (14 days between attempts 3+) and you can take a maximum of five attempts in a 12-month period. Each retake requires a new payment.
What Azure services are most heavily tested on AZ-900?
The most frequently tested areas are: core compute (Virtual Machines, App Service, Container Instances, AKS, Functions), core storage (Blob, Queue, Table, File, Disk), core networking (VNet, ExpressRoute, VPN Gateway, DNS, Load Balancer, Application Gateway, Azure Firewall), identity (Microsoft Entra ID and conditional access at a concept level), and governance (Azure Policy, Resource Locks, RBAC, Cost Management, Azure Monitor, Service Health). Cloud concepts (IaaS / PaaS / SaaS, public / private / hybrid, shared responsibility model, cloud economics) are tested in roughly a quarter of the questions.
How does AZ-900 differ from AZ-104 and AZ-305?
AZ-900 is Fundamentals tier — conceptual, broad, no hands-on configuration. AZ-104 (Administrator Associate) is hands-on operations: deploying VMs, managing storage, configuring VNets, monitoring, backup. AZ-305 (Solutions Architect Expert) is design-focused at the architecture level. AZ-900 is the recommended starting point if you have no Azure experience, but it is not a prerequisite for the Associate or Expert tiers — you can sit them in any order. Many candidates use AZ-900 as a warm-up before AZ-104.
Is AZ-900 worth taking for non-technical professionals?
Yes. AZ-900 is one of the few cloud certifications explicitly designed for non-technical audiences. Business analysts, project managers, sales engineers, marketing professionals, and executives who interact with cloud projects benefit from the shared vocabulary it builds — IaaS / PaaS / SaaS, regions and availability zones, shared responsibility, cost management — without requiring any hands-on configuration. The credential is often used as a hiring signal that someone can speak credibly about Azure in commercial conversations.
