The Check Point Firewall Kernel is the core component of the Gaia operating system and an integral part of traffic inspection process. There are two procedures available for debugging the firewall…

Explanation

fw ctl debug (and its kernel-level alias kdebug) is the correct command for detailed firewall kernel debugging - it enables verbose, granular inspection of traffic processing and requires significantly more CPU and memory resources, making it the heavier of the two available procedures.

Why the distractors are wrong:

• A (fw debug/kdebug) - Incorrect syntax; the ctl subcommand is required to interact with the kernel layer, so fw debug alone is not the right form.
• B (fw ctl zdebug) - This is actually the other procedure: zdebug is the lightweight, quick-capture method ("z" ≈ zero heavy overhead) used for fast, lower-impact debugging - the opposite of what the question asks.
• C (fw debug/kdebug ctl) - The word order is wrong; ctl must come before debug, not after.

Memory tip: Think of ctl as "control the kernel" - fw ctl debug gives you full control and full detail, at a full resource cost. fw ctl zdebug is the "zero-fuss" quick look. When the exam asks which method is heavier, pick the one without the "z."
