• C. Azure Application Insights is a monitoring service for application performance and health, not a deployment or configuration tool for installing software.
• D. Deployment Center in Azure App Service is for deploying web applications to Azure App Service, which is a PaaS offering, not for configuring software on IaaS Azure Virtual Machines or VM scale sets.
