During firewall kernel debug with fw ctl zdebug you received less information than expected. You noticed that a lot of messages were lost since the time the debug was started.
What should you do to resolve this issue?
A . Increase debug buffer; Use fw ctl debug Cbuf 32768
B . Redirect debug output to file; Use fw ctl zdebug Co ./debug.elg
C . Increase debug buffer; Use fw ctl zdebug Cbuf 32768
D . Redirect debug output to file; Use fw ctl debug Co ./debug.elg

A is the only logical option imo. But they need to use kdebug after increasing the buffer size. This question is open to interpretation.
A is not correct as this related to ‘fw ctl debug’ and not ‘fw ctl zdebug’ as stated in the question.
So based on this:
D is crossed off as this related to ‘fw ctl debug’
C is not valid as you cannot increase the buffer size on ‘fw ctl zdebug’ (1MB buffer size)
so that leave B as the only answer in my option.
