Check Point Certified Multi-Domain Security Management Specialist (CCMS) — Question 4

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 options

• A. Run command fw ctl set int fw1_kernel_all_disable=1
• B. Restore fwkern.conf from backup and reboot the gateway
• C. run fw unloadlocal to remove parameters from kernel
• D. Remove all kernel parameters from fwkern.conf and reboot

Correct answer: B

Explanation

Restoring fwkern.conf from backup is the correct action because it returns the kernel parameters to a known good state, which can resolve issues caused by incorrect settings. The other options either attempt to disable kernel functions or clear parameters without ensuring a stable configuration, which may not resolve the root cause of the problem.
