Microsoft Azure Architect Design (AZ-304) Practice Test

What is an optimal solution to deploy a web application that requires minimal maintenance and cost while being consistently accessible?

1. Azure App Service

2. Azure Virtual Machines

3. Azure Kubernetes Service

4. Azure Blob Storage

The correct answer is: Azure App Service

Deploying a web application using Azure App Service is an optimal solution because it is specifically designed for hosting web applications with minimal maintenance and lower costs compared to other options. Azure App Service is a fully managed platform that abstracts away much of the underlying infrastructure management work, meaning developers can focus on building and deploying their applications without worrying about server maintenance, scaling, or patching. This platform provides built-in features such as automatic updates, load balancing, and autoscaling, which ensure the application remains consistently accessible without requiring significant manual intervention. The pricing model of Azure App Service is also favorable for cost control, as it allows for easy scaling based on traffic and resource demands. This reduces costs when demand is low while still providing the necessary resources during peak loads. The other options, while capable of hosting web applications, involve greater management overhead. For example, Azure Virtual Machines require more configuration and maintenance, such as managing the OS and software updates. Azure Kubernetes Service facilitates container orchestration, which is powerful but introduces complexities in terms of deployment and management compared to App Service. Azure Blob Storage is not suitable for hosting traditional web applications as it is primarily designed for object storage and serving static content rather than dynamic web content. Hence, for a web application needing
