Full Tunnel VPN for Remote Access Traffic
Short answer
A Choose full tunnel so remote-access laptops send all traffic through the VPN to the corporate firewall for inspection.
Question
• Client laptops must start VPN software on startup.
• All traffic from remote access users must route through the corporate firewall.
Which of the following is the best way to meet these requirements?
Key Takeaways
The question tests the difference between full-tunnel remote access and other VPN models; the trap is selecting IPSec because it secures VPNs without defining whether all traffic is routed through the firewall.
This N10-009 VPN scenario tests whether full tunnel, IPSec, site-to-site, or clientless satisfies remote-access startup and firewall-inspection requirements. The correct choice is full tunnel (A), because it routes all remote-user traffic through the corporate firewall.
Common mistake: The most tempting wrong answer is IPSec (B) because it is a VPN security protocol, but it does not specify full-tunnel routing; only full tunnel ensures every remote-user packet reaches the corporate firewall.
Expert Analysis
The two requirements are qualifiers, not background. The question asks for the best way to satisfy both bullets: a software VPN client must start on each laptop, and every packet from remote users must go through the corporate firewall. The first bullet rules out designs that do not use an installed remote-access client; the second rules out any design that lets internet-bound traffic bypass the tunnel.
Option A matches the traffic-routing constraint. A full-tunnel VPN sends all traffic—corporate and internet-bound—through the encrypted tunnel to the corporate edge. Once the always-on client connects, the default route points into the tunnel, so the firewall can inspect, filter and log remote-user traffic. The supplied comment makes this point: full tunnel routes all traffic from the remote laptop through the VPN tunnel to the corporate firewall for inspection and access control. That is the decisive match.
The other options fail on one of the qualifiers. B, IPSec, is a protocol suite that can secure a VPN, but it does not by itself specify full versus split tunnelling or force startup behaviour; it is a mechanism, not the complete answer to the routing requirement. C, site-to-site VPN, connects networks such as a branch to headquarters; it does not install and launch a client on each remote laptop. D, clientless, uses a browser portal rather than VPN software on startup and typically exposes selected internal resources, not all remote-user traffic.
Conclusion. A is the only option that directly covers the all-traffic constraint while remaining consistent with a remote-access software client. The startup detail is implemented as an always-on VPN client; the full-tunnel configuration then ensures the corporate firewall sees all remote-user traffic.

Exam Strategy
When a VPN question lists two bullets, map each bullet to a feature and eliminate options that satisfy only one. Here, VPN software on startup points to an installed remote-access client, while all traffic through the firewall points to full tunnel rather than split tunnel. Treat protocol names such as IPSec as supporting mechanisms, not complete architectures, unless the question asks which protocol secures the tunnel.

ERB14 👍 1 Answered AA. Full tunnel: A full tunnel VPN configuration routes all network traffic from the remote user's laptop—including internal network traffic and public internet traffic—through the VPN tunnel to the corporate firewall for inspection, security filtering, and access control. This directly satisfies the requirement that "All traffic from remote access users must route through the corporate firewall".
