1.You run a free-command on a gateway and notice that the Swap column is not zero Choose the best
answer
A. Utilization of ram is high and swap file had to be used
B. Swap file is used regularly because RAM memory is reserved for management traffic
C. Swap memory is used for heavy connections when RAM memory is full
D. Its ole Swap is used to increase performance
Answer: A
2.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"?
A. Run command fw ctl set int fw1_kernel_all_disable=1
B. Restore fwkem.conf from backup and reboot the gateway
C. run fw unloadlocal to remove parameters from kernel
D. Remove all kernel parameters from fwkem.conf and reboot
Answer: B
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.”
