Difficulty: MediumRemote Access and Site-to-Site VPN Concepts

An enterprise is configuring a remote access VPN solution for mobile employees using Cisco AnyConnect client software. The network engineering team wants to implement split-tunneling to conserve corporate Internet bandwidth while maintaining secure connectivity to internal resources. Which two statements describe the operational behavior of split-tunneling in this remote access VPN deployment? (Select TWO.)

  1. Traffic destined for specified internal corporate IP subnets is encrypted and routed through the secure VPN tunnel.Answer
  2. Unencrypted Internet-bound traffic is routed directly out of the user's local network interface without traversing the corporate network.Answer
  3. C
    All user traffic, including public Internet browsing, is forcibly encrypted and forwarded through the central security gateway.
  4. D
    Split-tunneling establishes two concurrent site-to-site IPsec tunnels from the user endpoint to separate gateway routers.
  5. E
    The local endpoint default gateway is completely removed, preventing access to any local network devices such as local printers.

Answer

Split-tunneling encrypts and routes traffic destined for specified corporate subnets through the VPN tunnel, while allowing non-corporate Internet traffic to route directly via the endpoint's local interface.
In a remote access VPN deployment with split-tunneling configured, the VPN client receives a list of internal networks from the gateway. Traffic matching these corporate destination IP addresses is encrypted and encapsulated into the VPN tunnel. Traffic going to all other destinations (such as public websites) bypasses the tunnel and is sent directly out of the local network interface, saving corporate Internet bandwidth.

Step-by-Step Solution

1
Identify the primary operational mechanism of Remote Access VPN split-tunneling.
Split-tunneling separates traffic into two categories based on destination IP matching an access list or network scope defined on the gateway.
Only traffic destined for corporate subnets requires tunnel encapsulation.
2
Determine how corporate-bound and Internet-bound traffic are handled.
Corporate traffic is encrypted and sent through the VPN tunnel, while Internet-bound traffic bypasses the tunnel directly through the remote user's local gateway.
This reduces WAN latency and bandwidth consumption at the central corporate VPN gateway.
