Correct answer: a Desired State Configuration (DSC) extension.
Why this is the answer
A Desired State Configuration (DSC) extension is the correct choice because it allows you to define the desired state of your Windows Server VMs, including software installations like NGINX. When applied, DSC ensures that the specified configuration is consistently maintained across all instances in the scale set. The New-AzConfigurationAssignment cmdlet is used for Azure Automanage, which is a broader management service, not specifically for software installation within a VM scale set. Azure Active Directory (Azure AD) Application Proxy provides secure remote access to on-premises web apps, which is unrelated to VM configuration. Azure Application Insights is an Application Performance Management (APM) service for monitoring live web applications, not for deploying software.
