AZ-801 Question #45: Real Exam Question with Answer & Explanation

Question

You have an on-premises server that runs Windows Server and has the Web Server (IIS) server role installed. The server hosts a web app that connects to an on-premises Microsoft SQL Server database. You plan to migrate the web app to an Azure App Services web app. The database will remain on-premises. You need to ensure that the migrated web app can access the database. What should you configure in Azure?

Options

• Aan Azure SQL managed instance
• Ban on-premises data gateway
• CAzure Extended Network
• Da Hybrid Connection

Explanation

To ensure an Azure App Service web app can securely access an on-premises SQL Server database without migrating the database, a Hybrid Connection should be configured.

Common mistakes.

• A. An Azure SQL managed instance requires migrating the database to Azure, which contradicts the requirement for the database to remain on-premises.
• B. An on-premises data gateway is typically used for connecting Azure services like Logic Apps or Power BI to on-premises data sources, but Hybrid Connections are purpose-built for App Services to connect to on-premises resources.
• C. Azure Extended Network is a feature for stretching on-premises network subnets into Azure for VM migration, not for an Azure App Service connecting to an on-premises database.
