Explanation

vpn debug truncon (option D) is the correct Check Point command for enabling VPN debug logging to troubleshoot Site-to-Site VPN issues - truncon tells the system to truncate (reset) the log file and turn on debugging simultaneously, capturing clean output from the moment the issue occurs.

Why the distractors are wrong:

• A (vpn truncon debug) reverses the argument order, which is invalid syntax and will not execute.
• B (cp debug truncon) is not a recognized command; cp is not a valid Check Point CLI module for VPN debugging.
• C (fw debug truncon) is a real Check Point command, but it targets the firewall kernel (fw = FireWall module), not the VPN subsystem - it won't capture IKE/IPsec negotiation failures.

Memory tip: Think of it as a sentence - "VPN, debug: turn on (truncon)" - the module comes first (vpn), the action second (debug), and the mode last (truncon). The module prefix always tells you what you're debugging: vpn for tunnels, fw for packet inspection.
