Explanation

fw ctl zdebug is the correct answer because it is specifically designed as a lightweight kernel debugging tool that operates with a 1 MB buffer, making it ideal for monitoring packet drops and kernel events on production firewalls with minimal performance impact - the "z" hints at "zero-impact" debugging. Option B (fw ctl debug/kdebug) is the other valid kernel debugging procedure, but it uses a much larger buffer and consumes significantly more system resources, making it suited for deep-dive analysis rather than low-overhead troubleshooting. Option A (fw debug ctl) reverses the command syntax and is not a valid Check Point command. Option D (fwk ctl debug) is a fabricated command that does not exist in the Gaia OS toolkit.

Memory tip: Think of the "z" in zdebug as "zero overhead" - when you need to debug quickly and cheaply (especially packet drops), reach for zdebug; when you need the full firehose of kernel detail and can afford the resource cost, use kdebug.
