When troubleshooting VPN reachability, which networking detail should be verified to ensure resources can be reached?

• A. Local DNS server
• B. Printer queue
• C. Default gateway on VPN
• D. Wallpaper

Answer: (C)

When accessing resources across a VPN, the crucial factor is how traffic is routed through the VPN tunnel. The detail to verify is the VPN’s default gateway—the next hop that outbound traffic uses when the VPN is connected. If this gateway is incorrect, missing, or not reachable, packets destined for remote resources won’t be routed through the VPN, so reachability fails even though the VPN connection itself appears active. DNS settings can affect whether you can resolve hostnames, but reachability to resources on the remote network hinges on correct routing through the VPN gateway. The printer queue and wallpaper have no impact on network reachability to remote resources. To check the VPN gateway, inspect the routing table (for example, the default route that points to the VPN interface) and verify you can reach the VPN gateway and a known internal resource by IP. If direct IP tests fail, adjust the VPN configuration or contact support to ensure the tunnel’s default gateway is correctly configured.
