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

When should you use Azure Resource Manager?

1. To monitor resource use and generate management reports

2. To perform basic management tasks, such as starting and stopping a VM

3. To coordinate resource use between on-premises and cloud-based resources

4. To automate resource deployments using templates

The correct answer is: To automate resource deployments using templates

Using Azure Resource Manager to automate resource deployments using templates is the most appropriate choice. Azure Resource Manager (ARM) is designed to provide a systematic way of managing your resources through infrastructure as code. By using ARM templates, you can define the resources needed for your solution in a declarative way, and these templates can automate the deployment across multiple environments, ensuring consistency and repeatability. Automating resource deployments with templates allows teams to manage complex environments with ease. For instance, you can deploy entire environments with just a single command, significantly reducing the chances of human error and streamlining the process of infrastructure management. The other options, while related to resource management, do not capture the primary purpose of Azure Resource Manager as effectively. Monitoring resource use and generating management reports typically involves using tools like Azure Monitor rather than ARM directly. Performing basic management tasks such as starting and stopping a virtual machine can be done through various interfaces, including the Azure Portal, PowerShell, and CLI, without necessarily leveraging the full capabilities of Azure Resource Manager. Coordinating resource use between on-premises and cloud-based resources is more aligned with Azure Arc and hybrid solutions, rather than the specific deployment and management features provided by ARM.
