Deploying the SD-WAN controller on-premises offers several advantages, particularly in terms of control and customization.

Full Control of the Data Plane and the Control Plane: When the controller is deployed on-premises, the organization maintains complete control over both the data plane (traffic forwarding) and the control plane (network management and configuration). This allows for more granular control over network policies, security configurations, and performance optimizations.

Customization and Security: On-premises deployment allows organizations to customize their SD-WAN setup to meet specific security and compliance requirements. Sensitive data remains within the organization's control, which can be crucial for industries with strict data privacy regulations.

Operational Flexibility: Having the controller on-premises provides operational flexibility, enabling organizations to integrate the SD-WAN solution with existing network management tools and processes.

To allow VPN 10 traffic to have direct internet access locally from the WAN Edge device, the configuration must ensure that the traffic is routed correctly and that NAT (Network Address Translation) is applied to allow the traffic to exit to the internet.

Policy Configuration:

NAT Use: The configuration should include a directive to use NAT for the specific VPN (VPN 10 in this case). This ensures that the traffic originating from VPN 10 can be translated and routed to the internet.

Apply Policy: The policy should be applied in the outbound direction to the appropriate interface that connects to the internet.

Option A Analysis:

This option includes the nat use-vpn 0 directive, which instructs the system to use NAT for traffic in VPN 10, allowing it to access the internet directly.

The apply-policy command is correctly used to apply the policy to the site list and the data-policy DPI from-service.
