In a route-based site-to-site IPsec VPN configuration, which component is specifically responsible for directing outbound traffic destined for the remote network into the VPN tunnel interface?

### Why this is right - **An Internet Key Exchange (IKE) gateway** is true because it defines peer and local gateway information used to negotiate the connection. - **An Internet Protocol Security (IPsec) tunnel** is true because it binds the gateway to the tunnel interface and cryptographic profile. - **A static route to the remote local area network (LAN)** is true because routing directs remote-destination traffic into the tunnel. ### The concept VPN configuration has separate negotiation, protected-tunnel, and routing roles. Configuring only negotiation does not tell the firewall which destinations should use the VPN. A route supplies that forwarding decision. ### The other options - **A host's desktop wallpaper setting**: this has no role in firewall VPN negotiation, encryption, or routing. ### Terms - **IKE**: Internet Key Exchange, the protocol used to negotiate VPN security associations. - **IPsec**: Internet Protocol Security, a suite used to protect network traffic. - **LAN**: Local Area Network, the internal network at a site. ### Remember A working VPN needs peer negotiation, an IPsec tunnel, and a route for remote traffic.
