You plan to migrate an on-premises IIS web app (which connects to an on-premises SQL Server database) to Azure App Service, while leaving the database on-premises. What Azure component should you configure so the migrated App Service app can reach the on-premises database?

Correct answer: A Hybrid Connection.
Why this is the answer
A Hybrid Connection is the correct choice because it provides a secure, persistent, and bidirectional connection between an Azure App Service app and an on-premises resource, such as a SQL Server database, without requiring a VPN or opening firewall ports. This allows the App Service app to access the on-premises database as if it were on the same network. An Azure SQL Managed Instance is incorrect because it's a fully managed SQL database service in Azure, not a connectivity solution for on-premises databases. An on-premises data gateway is primarily used for Power BI, Azure Logic Apps, and Azure Analysis Services to connect to on-premises data sources, not directly for Azure App Service. Azure Extended Network is not a standard Azure networking component for this specific scenario.
