Why each option

Dynamic Dispatcher on a Check Point Security Gateway is fully enabled by running 'fw ctl multik set_mode 9' in Expert mode followed by a reboot; mode 9 specifically activates the Dynamic Dispatcher logic.

Arun fw ctl multik set_mode 9 in Expert mode and then rebootCorrect

Check Point's Dynamic Dispatcher is controlled via the 'fw ctl multik set_mode' command, and mode 9 enables the fully dynamic CoreXL dispatcher, which assigns connections to CPU cores based on real-time load rather than static hashing. A reboot is required for the change to take effect across all CoreXL instances.

BUsing cpconfig, update the Dynamic Dispatcher value to "full" under the CoreXL menu

cpconfig does not expose a 'Dynamic Dispatcher' menu option under CoreXL; this configuration is performed via Expert mode CLI commands, not the cpconfig interactive tool.

CEdit /proc/interrupts to include multik set_mode 1 at the bottom of the file, save, and reboot

The /proc/interrupts file is a read-only kernel interface that reports IRQ statistics; it cannot be edited to configure CoreXL dispatcher modes.

Drun fw ctl multik set_mode 1 in Expert mode and then reboot

'fw ctl multik set_mode 1' enables a different CoreXL mode (not Dynamic Dispatcher); mode 9 is specifically required to activate the Dynamic Dispatcher feature.
