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

What service provides the ability to automate deployment and scaling of applications?

1. Azure Functions

2. Azure App Service

3. Azure Kubernetes Service

4. Azure Batch

The correct answer is: Azure App Service

The correct answer is Azure App Service, which provides a platform for building, hosting, and scaling web applications, mobile app backends, and RESTful APIs. One of its key features is the ability to automate deployment and scaling, allowing developers to focus more on their code rather than on infrastructure management. Azure App Service offers built-in scaling options such as manual or automatic scaling based on demand, ensuring that applications can handle varying loads efficiently. It supports continuous deployment from various source control systems, and features like staging slots allow for safe and easy deployments. This makes it an ideal choice for developers looking for a quick and efficient way to manage their applications in the cloud. Other options, while important services within Azure, serve different purposes. For instance, Azure Functions is designed for serverless computing and executing code in response to events, focusing more on individual function deployment than managing complete applications. Azure Kubernetes Service, on the other hand, excels at container orchestration and requires more complex configurations for scaling, primarily aimed at microservices architectures. Azure Batch is geared towards running large-scale parallel and high-performance computing (HPC) applications but does not offer the same level of direct support for web application hosting and scaling as Azure App Service.
