Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which Azure service offers serverless computing capabilities?

1. Azure Functions

2. Azure VM

3. Azure SQL Database

4. Azure Blob Storage

The correct answer is: Azure Functions

The correct choice, Azure Functions, is a key player in the serverless computing landscape on Azure. Serverless computing allows developers to focus on writing code without having to manage the underlying infrastructure. With Azure Functions, you can run event-driven code in response to various triggers such as HTTP requests, message queues, or timers. This means you only pay for the compute resources when your code is executed, leading to cost efficiency and scalability, as the service automatically adjusts based on demand. In contrast, Azure Virtual Machines require you to provision and manage servers, which involves handling the operating system, patches, and other maintenance tasks. Azure SQL Database, while a managed database service, does not fit the typical definition of serverless computing because it involves database management and provisioning. Azure Blob Storage primarily serves as an object storage solution rather than a platform for executing code. Thus, Azure Functions stands out as the clear choice for serverless capabilities.
