QuestionQ13

Advanced Kernel Debugging

The two procedures available for debugging the firewall kernel are:

  1. fw ctl zdebug
  2. fw ctl debug/kdebug

Choose the statement that correctly explains the difference between the two.

Detailed kernel debugging uses fw ctl debug to configure debug flags and buffer settings, followed by fw ctl kdebug to collect the debug output; this workflow supports more extensive diagnostic capture.
