What the AZ-900 Exam Actually Tests
Before diving into practice questions, it helps to understand exactly what Microsoft is measuring. The AZ-900 Certification is a proctored, computer-based fundamentals exam administered through Pearson VUE - either at an authorized test center or via the Pearson OnVUE online proctoring platform. Certiport scheduling is also available for students and educators where applicable.
The exam is designed for candidates who want to demonstrate baseline familiarity with cloud concepts and Microsoft Azure services. There are no prerequisites; you do not need prior certifications or a specific job title to register. That said, Microsoft's own guidance positions AZ-900 as best suited for candidates who already have some exposure to IT areas such as infrastructure, databases, or software development. Candidates with zero technical background will find the material more challenging than the "fundamentals" label implies.
If you are still orienting yourself to the certification, the article What Is AZ-900? covers the purpose and audience of the exam in depth. For a broader orientation to the skills measured, the AZ-900 Exam Domains 2026: Complete Guide to All 3 Content Areas is an essential companion to this practice-question walkthrough.
Domain-by-Domain Question Breakdown
The AZ-900 blueprint is divided into three domains. Knowing how much weight each domain carries lets you allocate study time rationally rather than treating all topics as equally important.
Domain 1: Describe Cloud Concepts (25-30%)
This domain covers the foundational vocabulary and principles of cloud computing - concepts every Azure question ultimately builds on. Questions here test whether you can distinguish between cloud service models, deployment models, and core economic benefits.
- IaaS, PaaS, and SaaS definitions and real-world examples
- Public, private, and hybrid cloud deployment models
- High availability, scalability, elasticity, agility, and fault tolerance
- Capital expenditure (CapEx) vs. operational expenditure (OpEx)
- The consumption-based model and how it differs from on-premises pricing
Domain 2: Describe Azure Architecture and Services (35-40%)
This is the heaviest domain and the one where most candidates lose or gain their margin of victory. Questions span Azure's global infrastructure, core compute and storage services, networking, and identity/security fundamentals.
- Azure regions, region pairs, availability zones, and sovereign clouds
- Azure Virtual Machines, Azure App Service, Azure Container Instances, Azure Kubernetes Service
- Azure Blob Storage, Azure Files, Azure Queue Storage, and storage tiers
- Azure Virtual Network, VPN Gateway, ExpressRoute, and Azure DNS
- Microsoft Entra ID (formerly Azure Active Directory), role-based access control (RBAC)
- Azure Key Vault, Microsoft Defender for Cloud, and DDoS Protection
Domain 3: Describe Azure Management and Governance (30-35%)
This domain focuses on how organizations control costs, enforce policies, and manage resources at scale. Questions frequently involve scenario-based reasoning - "a company needs to ensure all VMs have a specific tag; which tool do they use?"
- Azure Cost Management and Pricing Calculator vs. Total Cost of Ownership Calculator
- Azure Policy, Azure Blueprints (now superseded in part by deployment stacks), and management groups
- Azure Resource Manager (ARM) templates and Azure Arc
- Azure Monitor, Azure Service Health, and Azure Advisor
- Microsoft Cloud Adoption Framework and Microsoft Purview governance

Question Formats and Item Types
Microsoft does not pre-announce the exact item types that will appear on AZ-900, but the exam platform supports interactive components in addition to traditional multiple-choice questions. Based on the published exam format, candidates should be comfortable with:
- Single best answer (multiple choice): One correct answer from four options. The most common format across all three domains.
- Multiple select: "Select all that apply" or "Choose two answers." These are unforgiving - partial credit is not guaranteed, so precision matters.
- Drag-and-drop / matching: Match a service to its category or drag a feature to the correct tier. These often appear for storage types or service models.
- Yes/No or True/False answer sets: A scenario followed by a series of statements where you confirm or deny each. Read each statement independently.
- Ordering / sequencing: Arrange steps in the correct order, often related to deployment or security workflows.
High-Value Topics That Appear Most Often
Because Domain 2 carries 35-40% of the exam weight, Azure architecture and services questions will dominate your exam experience. Within that domain, certain topics surface repeatedly in practice exams and align tightly with the skills measured for the July 2026 update:
- Availability zones vs. availability sets: A classic confusion point. Availability zones are physically separate datacenters within a region; availability sets protect VMs within a single datacenter.
- Azure storage redundancy options: LRS, ZRS, GRS, and GZRS - what each protects against and when you would choose one over another.
- Azure Entra ID vs. on-premises Active Directory: Entra ID is not a direct cloud lift of on-premises AD; it is an identity platform built for web-based authentication.
- Shared responsibility model: This concept spans Domain 1 and Domain 2. Know exactly what Microsoft manages vs. what the customer manages in IaaS, PaaS, and SaaS scenarios.
- Azure Policy vs. RBAC: Policy controls what can be done with resources; RBAC controls who can perform actions. These are complementary, not interchangeable.
Weak performance on Domain 2 is the most common reason candidates fall short of the 700 threshold. Supplementing your reading with full-length timed practice tests on the AZ-900 Exam Prep practice test platform helps you identify which Architecture and Services subtopics need the most reinforcement before exam day.
Representative Practice Questions by Domain
The following questions are representative of the style and difficulty level of AZ-900 exam items. They are not leaked or actual exam questions - they are original examples constructed to match the documented skills measured.
Domain 1 - Cloud Concepts
Question: A company wants to move its email platform to a cloud service where the provider manages the underlying infrastructure, operating system, and application. Employees simply log in and use the service. Which cloud service model does this describe?
Answer: SaaS (Software as a Service). The customer has no management responsibility for infrastructure or application layers.
Domain 2 - Azure Architecture and Services
Question: Your organization requires that virtual machines remain available even if an entire Azure datacenter within a region fails. Which Azure feature should you configure?
Answer: Availability Zones. Availability zones are physically separate datacenters within a region; they protect against datacenter-level failure. Availability sets only protect against rack-level failures within a single datacenter.
Question: A development team needs a storage solution for unstructured data such as images, videos, and log files. Which Azure storage service is most appropriate?
Answer: Azure Blob Storage. Blob storage is optimized for storing massive amounts of unstructured object data.
Domain 3 - Management and Governance
Question: An enterprise wants to ensure that no Azure resources are deployed to regions outside of Europe. Which Azure tool enforces this constraint?
Answer: Azure Policy. Azure Policy evaluates resources for compliance and can deny deployments that violate defined rules, such as allowed region lists.
Question: A cloud architect wants to estimate the monthly cost of a proposed Azure workload before deployment. Which tool should they use?
Answer: Azure Pricing Calculator. The Pricing Calculator is used to estimate costs for new workloads. The TCO Calculator is used to compare on-premises costs against Azure costs.
Key Takeaway
When reviewing practice answers, always ask why the wrong options are wrong - not just why the correct answer is correct. AZ-900 distractor options are carefully crafted to catch candidates who have surface-level familiarity with Azure service names but lack conceptual precision.
Scoring, Passing Threshold, and Guessing Strategy
Microsoft uses a scaled scoring system where raw correct answers are converted to a score between 1 and 1000. The passing threshold for AZ-900 is 700. Microsoft does not publish the exact conversion formula, and the number of questions can vary between exam administrations - so focus on conceptual mastery rather than calculating a minimum number of correct responses.
There is no penalty for guessing on AZ-900. If you are uncertain about an answer, eliminate clearly incorrect options first and select the most defensible remaining choice. Never leave an answer blank. On scenario-based questions with multiple correct selections, apply the same logic - partial responses still carry risk on "select exactly two" formats, so make your best complete selection.

A Domain-Weighted Study Schedule
If you have three weeks before your exam date, a domain-weighted approach ensures you spend the most time where the exam allocates the most points.
Domain 1 - Cloud Concepts (25-30%)
- Master IaaS / PaaS / SaaS distinctions with real Azure service examples
- Map all cloud benefits (HA, scalability, elasticity, agility, DR) to Azure features
- Complete 30-40 Domain 1 practice questions daily, reviewing every wrong answer
- Finish the week with a timed Domain 1-only mini-exam to measure baseline accuracy
Domain 2 - Azure Architecture and Services (35-40%)
- Build a mental map of Azure global infrastructure: regions → region pairs → availability zones
- Study compute, storage, networking, and identity services in dedicated daily blocks
- Use flashcards for service-to-category matching (prep for drag-and-drop questions)
- Run full-length timed practice tests on the AZ-900 Exam Prep platform and track Domain 2 accuracy separately
Domain 3 - Management and Governance (30-35%) + Full Review
- Focus on cost management tools, Azure Policy, and monitoring services
- Complete two or three full-length 60-question timed practice exams
- Target any subtopic where your accuracy falls below 75%
- Review the shared responsibility model across all three service models one final time
For a more comprehensive structured approach beyond this three-week framework, the AZ-900 Study Guide 2026: How to Pass on Your First Attempt covers resource selection, Microsoft Learn path sequencing, and time-commitment benchmarks in detail.

Frequently Asked Questions
Microsoft states that most certification exams contain 40-60 questions and that the AZ-900 is a 45-minute assessment. The exact question count can vary between administrations, and some items may be unscored. Plan for the full possible range rather than counting on a specific number.
Domain 2 - Describe Azure architecture and services - carries the highest weight at 35-40% of the exam. If you have limited study time, invest the largest share in mastering Azure compute, storage, networking, and identity services before drilling the other two domains.
No. Microsoft explicitly states there is no penalty for guessing on AZ-900. Always submit an answer for every question - eliminate what you can and make your best selection. Leaving a question blank guarantees zero points; guessing gives you a nonzero chance of credit.
Microsoft Fundamentals certifications do not expire and renewal does not apply. Once you pass AZ-900 and earn the Microsoft Certified: Azure Fundamentals badge, it remains permanently on your transcript without any renewal requirement.
Use practice questions in two modes: untimed topic-specific drilling early in your prep to identify knowledge gaps by domain, then timed full-length exams in the final week to simulate the 45-minute exam pressure. Review every incorrect answer at the conceptual level - understand the principle behind the correct choice, not just which letter to select. The AZ-900 Exam Prep practice test platform provides domain-tagged questions so you can isolate weak areas by the three official content domains.
