B) In this document, the messages are stored in /var/log/messages Important - The CPU load increases at this point because the Firewall kernel starts to write some debug messages to the /var/log/messages file and the dmesg buffer. https://sc1.checkpoint.com/documents/R81/WebAdminGuides/EN/CP_R81_NextGenSecurityGateway_Guide/Topics-FWG/Kernel-Debug/Kernel-Debug-Procedure.htm

The Correct Answer A CCSM R80 Study guide pg 93. The Kernel mode process writes debug messages to the buffer. Therefore, it is necessary to define a sufficient buffer, using the following command: fw ctl debug -buf <buffer size> … this is also why an error message, generated outside of a debug, is sent to the console and an error message, generated during a debug, is sent to the debug buffer with all the other debug information.

B is the Answer: Page 180 on the studenty book: When debug information is sent to the operating system, the inf ormation is referred to as a console message because in most operating systems, the messages are printed to the console and copied to /var/log/messages
