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 Core Services
Which Azure service would you use to implement serverless computing?
- A. Azure Kubernetes Service
- B. Azure Functions (Correct answer)
- C. Azure SQL Database
- D. Azure App Service
Correct answer: B
Explanation: Azure Functions is a serverless compute service that allows you to run event-driven code without having to explicitly provision or manage infrastructure. Azure Kubernetes Service (A) is for container orchestration, Azure SQL Database (C) is a relational database service, and Azure App Service (D) is for hosting web apps.
Sample Question 4 — Azure Core Services
Which Azure service is best suited for storing and retrieving large binary files?
- A. Azure Table Storage
- B. Azure Blob Storage (Correct answer)
- C. Azure File Storage
- D. Azure Queue Storage
Correct answer: B
