NEW QUESTION # 74
You modified kernel parameters and after rebooting the gateway, a lot of production traffic gets dropped and the gateway acts strangely What should you do"?
Answer: D
Explanation:
If you have modified kernel parameters (in fwkern.conf, for example) and the gateway starts dropping traffic or behaving abnormally after a reboot, the best practice is to restore the original or a known-good configuration from backup. Then, reboot again so that the gateway loads the last known stable settings.
Option A (fw ctl set int fw1_kernel_all_disable=1) is not a standard or documented method for "undoing" all kernel tweaks.
Option B (Restore fwkem.conf from backup and reboot the gateway) is the correct and straightforward approach.
Option C (fw unloadlocal) removes the local policy but does not revert custom kernel parameters that have already been loaded at boot.
Option D (Remove all kernel parameters from fwkem.conf and reboot) might help in some cases, but you risk losing other beneficial or necessary parameters if there were legitimate custom settings. Restoring from a known-good backup is safer and more precise.
Hence, the best answer:
"Restore fwkem.conf from backup and reboot the gateway."

NEW QUESTION # 75
When a User Mode process suddenly crashes, it may create a core dump file. Which of the following information is available in the core dump and may be used to identify the root cause of the crash?
i. Program Counter
ii. Stack Pointer
iii. Memory management information
iv. Other Processor and OS flags / information
Answer: B
Explanation:
A core dump file is essentially a snapshot of the process's memory at the time of the crash. This snapshot includes crucial information that can help diagnose the cause of the crash. Here's why all the options are relevant:
i. Program Counter: This register stores the address of the next instruction the CPU was supposed to execute. It pinpoints exactly where in the code the crash occurred.
ii. Stack Pointer: This register points to the top of the call stack, which shows the sequence of function calls that led to the crash. This helps trace the program's execution flow before the crash.
iii. Memory management information: This includes details about the process's memory allocations, which can reveal issues like memory leaks or invalid memory access attempts.
iv. Other Processor and OS flags/information: This encompasses various registers and system information that provide context about the state of the processor and operating system at the time of the crash.
By analyzing this information within the core dump, you can often identify the root cause of the crash, such as a segmentation fault, null pointer dereference, or stack overflow.
Check Point Troubleshooting Reference:
While core dumps are a general concept in operating systems, Check Point's documentation touches upon them in the context of troubleshooting specific processes like fwd (firewall) or cpd (Check Point daemon). The fw ctl zdebug command, for example, can be used to trigger a core dump of the fwd process for debugging purposes.
