AZ-900 Practice Questions: 10 Free Sample Questions with Answers (2026)

How to Use These Practice Questions

Read each question carefully, pick your answer, then scroll down to the explanation. These questions cover all three AZ-900 domains: cloud concepts, Azure architecture and services, and Azure management and governance. Each is representative of the difficulty and style you will encounter on exam day.

After you finish these 10, the full ReadRoost AZ-900 pack has 400 practice questions and 200 flashcards with spaced repetition tracking starting at $4.99 AUD.

Question 1 -- Cloud Service Models (Domain: Cloud Concepts)

An organisation evaluates moving its email system to cloud-based Office 365. What type of cloud service model is this, and who manages the infrastructure? A) IaaS; the organisation manages everything B) PaaS; Microsoft manages applications only C) SaaS; Microsoft manages applications, infrastructure, and updates D) Private cloud; the organisation manages infrastructure

Answer: C Office 365 is a SaaS offering where Microsoft provides the complete application, handles all infrastructure, patches, updates, and security. Users simply access the service via web browsers or clients. In SaaS, the customer is only responsible for data management and user access control.

Question 2 -- Cloud Pricing Models (Domain: Cloud Concepts)

A manufacturing company needs consistent, predictable performance for mission-critical systems and plans significant capital investment in infrastructure. Which cloud pricing model should they consider? A) Pay-as-you-go consumption pricing B) Reserved instances with long-term commitment discounts C) Spot instances for cost optimisation D) Serverless pay-per-execution pricing

Answer: B Reserved instances provide discounts for long-term commitments (1-3 years), making them ideal when workload requirements are predictable and consistent. Pay-as-you-go offers flexibility but higher per-unit costs, spot instances are for fault-tolerant workloads only, and serverless suits highly variable workloads.

Question 3 -- Hybrid Cloud (Domain: Cloud Concepts)

A healthcare provider uses a combination of on-premises systems for patient records and cloud-based analytics services. This deployment approach is an example of which cloud model? A) Public cloud B) Private cloud C) Hybrid cloud D) Community cloud

Answer: C Hybrid cloud combines on-premises infrastructure with cloud services. This scenario uses on-premises patient records (sensitive data with control requirements) and cloud-based analytics (leveraging cloud scalability). Neither pure public nor pure private cloud alone describes this deployment.

Question 4 -- PaaS Security Benefits (Domain: Cloud Concepts)

An organisation discovers that its security team lacks expertise in managing infrastructure but needs to deploy secure systems quickly. Which cloud benefit addresses this gap? A) Managed PaaS services with built-in security controls and compliance baselines B) IaaS with full control allowing custom security implementation C) SaaS for all applications eliminating security concerns entirely D) Hybrid cloud maintaining some on-premises control

Answer: A Managed PaaS services embed security controls and compliance frameworks, reducing the expertise and effort required from internal teams. IaaS still requires you to manage OS and network security. SaaS does not eliminate all security concerns (you still manage data and access), and hybrid cloud adds complexity rather than reducing it.

Question 5 -- Identifying SaaS (Domain: Cloud Concepts)

A financial services company uses Microsoft 365 for email, document collaboration, and team communication. Which cloud service model does this represent? A) Infrastructure as a Service (IaaS) B) Platform as a Service (PaaS) C) Software as a Service (SaaS) D) Backup as a Service (BaaS)

Answer: C Microsoft 365 is a textbook SaaS example. Users access fully managed applications without touching any underlying infrastructure. Microsoft handles patching, scaling, and availability. BaaS is not a standard Azure service model.

Question 6 -- IaaS Use Case (Domain: Cloud Concepts)

A manufacturing company needs to run legacy custom applications that require specific hardware configurations. Which cloud service model would provide the flexibility and control needed? A) Platform as a Service (PaaS) B) Software as a Service (SaaS) C) Infrastructure as a Service (IaaS) D) Serverless Computing

Answer: C IaaS provides virtualised computing resources where you control the operating system, middleware, and runtime environment. This is essential for legacy applications that require specific OS versions or hardware configurations. PaaS abstracts the OS away, SaaS provides finished applications, and serverless removes server management entirely.

Question 7 -- Cost Management (Domain: Management & Governance)

Your company runs multiple Azure subscriptions across different departments. Management wants a single view of costs and the ability to set spending limits per department. Which Azure tools should you use? A) Azure Advisor and Azure Service Health B) Microsoft Cost Management and Azure Budgets C) Azure Monitor and Log Analytics D) Azure Policy and Azure Blueprints

Answer: B Microsoft Cost Management provides unified cost reporting across subscriptions, and Azure Budgets lets you set spending thresholds with alerts. Azure Advisor provides optimisation recommendations but is not a cost reporting tool. Azure Policy enforces rules but does not track spending. Cost management is one of the most commonly tested topics on the AZ-900.

Question 8 -- Azure Infrastructure (Domain: Architecture & Services)

What is the relationship between Azure datacentres, availability zones, and regions? A) A region contains multiple datacentres; an availability zone is a single datacentre B) A region contains availability zones; each availability zone is one or more physically separate datacentres C) An availability zone contains multiple regions D) Datacentres and availability zones are the same thing

Answer: B Azure regions contain availability zones, and each availability zone consists of one or more physically separate datacentres with independent power, cooling, and networking. This hierarchy provides fault isolation at multiple levels. Understanding this relationship is a common AZ-900 exam topic.

Question 9 -- Availability Zones (Domain: Architecture & Services)

What is the key difference between zone-redundant and zonal resource deployments? A) They have identical responsibility models B) Zone-redundant deployments handle failover automatically by Azure; zonal deployments require you to manage failover C) Zonal deployments provide better latency D) Only zone-redundant deployments support availability zones

Answer: B Zone-redundant deployments are managed by Azure with automatic distribution and failover across availability zones. Zonal deployments pin a resource to a specific zone and leave failover planning to you. Both use availability zones, but the responsibility model differs.

Question 10 -- Sovereign Regions (Domain: Architecture & Services)

Your organisation spans multiple countries and uses both sovereign and standard Azure regions. What is the most important architectural consideration? A) Sovereign and standard regions can freely replicate data B) Network latency is identical between region types C) Service availability differences must be carefully evaluated, as sovereign regions offer limited services D) All subscriptions must be in the same tenant

Answer: C Sovereign cloud regions (such as Azure Government and Azure China) often have limited service availability compared to standard Azure regions due to regulatory and compliance requirements. Architects must verify which services are available before designing solutions that span both region types.

What Makes Good AZ-900 Practice Questions?

The best practice questions mirror the real exam in both format and difficulty. The AZ-900 uses multiple-choice and multi-select questions. Scenario-based questions are common, where you must apply concepts to realistic business situations rather than simply recall definitions.

Avoid practice tests that are too easy or that test obscure trivia. The AZ-900 focuses on practical understanding: when to use IaaS vs PaaS vs SaaS, how Azure pricing works, what each compliance tool does, and how to choose the right service for a given scenario.

ReadRoost questions are AI-curated and mapped to official Microsoft exam objectives. Every question includes a detailed explanation of why the correct answer is right and why each distractor is wrong, turning each practice attempt into a learning opportunity.
