Your customer wants to ensure that their corporate browser always goes through VPN, but at the same time, they want to implement the best configuration to reduce unnecessary traffic over the corporate VPN. What VPN configuration would best fit the customer's specific requirements?

Per-App VPN is the best solution because it allows specific applications, like the corporate browser, to route their traffic through the VPN while other applications can access the internet directly. This selectively encrypts and routes only necessary corporate traffic, reducing the load on the VPN server and optimizing network performance. Always-On VPN would route all device traffic through the VPN, which is inefficient and generates unnecessary traffic. Per-Profile VPN is not a standard Android Enterprise VPN configuration option. User-Initiated VPN requires manual activation, which doesn't guarantee that the corporate browser traffic always goes through the VPN.
