会社のセキュリティポリシーでは、リモート従業員の社内ノートパソコンからのすべてのネットワークトラフィックに会社のVPNを使用することが義務付けられています。このシナリオに最も適したネットワークアクセス方法は、次のうちどれですか?
正解:B
The correct answer is Full-tunnel because the policy requires all network traffic from remote corporate laptops to pass through the company's VPN. In a full-tunnel VPN configuration, once the VPN connection is established, all traffic-including internet-bound traffic-is routed through the corporate network before reaching its destination. This ensures centralized monitoring, content filtering, logging, and enforcement of security controls such as IDS/IPS and firewalls.
According to CompTIA Network+ (N10-009) security objectives, full-tunnel VPNs enhance security by preventing users from directly accessing the internet from their local connection, thereby reducing exposure to local network threats (e.g., public Wi-Fi attacks).
A split-tunnel VPN (Option D) allows users to access the internet directly while only sending corporate- bound traffic through the VPN, which does not meet the "all traffic" requirement. A site-to-site tunnel (Option C) connects entire networks rather than individual remote users. A clientless VPN (Option A) typically provides web-based access without a full network tunnel and does not necessarily route all traffic.
Therefore, full-tunnel best matches the policy requirement.
