What do ARM templates allow you to do in Azure?

1. Backup virtual machines automatically

2. Manage application logs more effectively

3. Deploy and manage resources consistently

4. Optimize network bandwidth usage

The correct answer is: Deploy and manage resources consistently

ARM templates, or Azure Resource Manager templates, are a powerful feature in Azure that facilitate the deployment, management, and organization of Azure resources in a consistent and repeatable manner. By defining the infrastructure and configuration of your Azure solutions in a JSON format, ARM templates enable you to deploy multiple resources together as a unit, also known as a resource group. The primary advantage of using ARM templates is their ability to provision resources in a declarative way. This means that you can specify what resources you want instead of how to create them, allowing Azure to handle the orchestration of the deployment. This consistency is crucial for environments where multiple deployments need to be managed, as it minimizes the risk of human error and enforces standardization. Furthermore, ARM templates support parameters, variables, and conditions, making it easier to customize deployments depending on the environment (development, staging, production). This flexibility enhances the ability to maintain consistency across different environments and supports infrastructure as code principles. In contrast, options related to backing up virtual machines, managing application logs, or optimizing network bandwidth usage do not directly pertain to the use of ARM templates. These functionalities are better served by different Azure services or tools specifically designed for those purposes.
