8 Free AZ-900 Sample Questions with Answers
Each question below includes 4 answer options, the correct answer, and a detailed explanation. These are real questions from the FlashGenius AZ-900 question bank.
Sample Question 1 — Azure Core Services
Which Azure service is primarily used for hosting web applications and APIs?
- A. Azure Functions
- B. Azure App Service (Correct answer)
- C. Azure Virtual Machines
- D. Azure Blob Storage
Correct answer: B
Explanation: Azure App Service is a fully managed platform for building, deploying, and scaling web apps. It supports multiple programming languages and frameworks, making it ideal for hosting web applications and APIs. Azure Functions (A) is used for serverless computing, Virtual Machines (C) provide IaaS for various applications, and Blob Storage (D) is used for storing unstructured data.
Sample Question 2 — Azure Core Services
What is the primary purpose of Azure Virtual Network?
- A. To store large amounts of unstructured data
- B. To create virtual machines
- C. To isolate and secure network resources (Correct answer)
- D. To provide identity and access management
Correct answer: C
Explanation: Azure Virtual Network (VNet) is used to create isolated and secure network environments in Azure. It allows you to securely connect Azure resources to each other and to on-premises networks. Storing data (A), creating VMs (B), and identity management (D) are not the primary purposes of VNets.
Sample Question 3 — Azure Pricing and Support
Which Azure pricing model allows you to pay for cloud services based on actual usage?
- A. Reserved Instances
- B. Pay-As-You-Go (Correct answer)
- C. Enterprise Agreement
- D. Free Tier
Correct answer: B
Explanation: The Pay-As-You-Go pricing model allows customers to pay for Azure services based on actual usage without any upfront commitment. This is ideal for users who need flexibility and scalability. Reserved Instances require upfront payment, Enterprise Agreements are for large organizations with specific contracts, and the Free Tier provides limited free services.
Sample Question 4 — Azure Pricing and Support
What is the primary benefit of using Azure Cost Management and Billing?
- A. To increase the speed of data processing
- B. To monitor and optimize cloud spending (Correct answer)
- C. To enhance security features
- D. To automate deployment processes
Correct answer: B
Explanation: Azure Cost Management and Billing is designed to help users monitor, allocate, and optimize their cloud spending. It provides tools to analyze costs, set budgets, and forecast future expenses. It does not directly affect data processing speed, security features, or deployment automation.
Sample Question 5 — Cloud Concepts
What is a key benefit of using cloud computing for businesses?
- A. Increased hardware maintenance costs
- B. Scalability and flexibility (Correct answer)
- C. Limited access to global markets
- D. Higher upfront capital expenditure
Correct answer: B
Explanation: Cloud computing offers scalability and flexibility, allowing businesses to adjust resources as needed without significant capital investment. This contrasts with traditional IT infrastructure, which often requires substantial upfront costs and ongoing maintenance. Options A, C, and D are incorrect because cloud computing typically reduces hardware costs, provides global access, and lowers initial capital expenses.

Which of the following describes a public cloud deployment model?
- A. Resources are owned and operated by a single organization
- B. Resources are shared by multiple organizations with common concerns
- C. Resources are available to the general public over the internet (Correct answer)
