What networking feature can be used within App Service to manage outbound network traffic?

1. App-assigned address

2. Hybrid Connections

3. Service endpoints

4. VNet Integration

The correct answer is: Hybrid Connections

The correct choice is Hybrid Connections. Hybrid Connections is a feature in Azure App Service that allows applications to connect securely to on-premises resources or other services that are not directly accessible over the internet. This feature essentially creates a bridge, allowing outbound traffic from the Azure App Service to reach those on-premise resources while maintaining security. By using Hybrid Connections, developers can manage outbound network traffic effectively, especially when it comes to applications that require access to internal databases or APIs that are hosted behind a corporate firewall. This is essential for maintaining a high level of security while still enabling cloud applications to communicate with necessary services. Other options like App-assigned address, Service endpoints, and VNet Integration serve different purposes. App-assigned addresses refer to specific IP addresses that can be assigned to applications for outbound traffic but do not generally enhance security or manage traffic the same way Hybrid Connections do. Service endpoints provide secure connectivity to Azure services but are not meant for routing traffic to on-premises networks. VNet Integration enables your App Service to access resources in a virtual network, making it suitable for integration scenarios but does not directly manage outbound traffic like Hybrid Connections does.
