To fully enable Dynamic Dispatcher on a Security Gateway, what is the required action?

To fully enable Dynamic Dispatcher on a Security Gateway, running the command in Expert mode is a critical step. Specifically, the command fw ctl multik set_mode 9 configures the Gateway to operate in a mode where it can efficiently utilize multiple CPU cores. This command adjusts how packet processing is distributed among the available cores, enhancing performance by allowing parallelized handling of traffic.

After executing the command, a reboot is required for the changes to take effect. This ensures that the Security Gateway applies the new configuration settings from the start, allowing Dynamic Dispatcher to function at its optimal level right from the system initialization.

In the context of the other options, they do not correctly address the thorough activation of Dynamic Dispatcher. Modifying configurations through cpconfig or editing system files directly may not appropriately configure dynamic dispatching or may involve an incorrect approach to affecting core processing capabilities. Thus, using the specified command and rebooting is indeed the validated process for fully enabling Dynamic Dispatcher on the Security Gateway.
