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…

An Azure Desired State Configuration (DSC) extension can be included in an ARM template for a virtual machine scale set to automatically install and configure software like NGINX on all instances after they are deployed.

Microsoft Intune is a cloud-based service for mobile device management (MDM) and mobile application management (MAM), primarily for end-user devices, not for configuring server-side software on Azure VMs in a scale set.

The Publish-AzVMDscConfiguration cmdlet uploads a DSC configuration to Azure Storage, which is a preparatory step, but it does not actually apply the configuration to the virtual machines itself.

The New-AzConfigurationAssignment cmdlet is used for Azure Policy guest configuration assignments, which are typically for auditing or enforcing compliance rather than initial software deployment for a VMSS via an ARM template.
