AZ-104 Certification Practice Question #176

Question

You plan to deploy several Azure virtual machines that will run Windows Server 2019 in a virtual machine scale set by using an Azure Resource Manager template.
You need to ensure that NGINX is available on all the virtual machines after they are deployed.
What should you use?

Accepted Answer

To automate post-deployment configuration tasks, such as installing and configuring the NGINX web server on Windows Server VMs in a virtual machine scale set during provisioning, Azure VM extensions should be used. The **Desired State Configuration (DSC) extension** allows administrators to define the desired state of a VM (e.g., ensuring NGINX is installed and running) in a script and apply it automatically as part of the ARM template deployment. Another commonly tested correct option is the Custom Script Extension, but because only DSC is listed among the choices, B is the correct answer.
