 The correct description for the Dynamic Balancing / Split feature is:

• Dynamic Balancing / Split dynamically change the number of SND’s and firewall instances based on the current load.
• It is only available on Quantum Appliances (not on Quantum Spark or Open Server)

The Dynamic Balancing / Split feature is a performance-enhancing daemon that balances the load between CoreXL SNDs and CoreXL Firewalls. It monitors the average CPU utilization of CoreXL Firewall and SND instances and automatically increases or decreases the number of CoreXL Firewall instances. The Dynamic Balancing Daemon (dsd) has three stages in each iteration: Examine the current CPU utilization, Calculate the optimal split, and Apply the new split1.

The Dynamic Balancing / Split feature is supported on Check Point Appliances, such as Quantum Appliances, Quantum Maestro, Quantum Security Gateways, and Quantum LightSpeed Appliances in KPPAK mode2. It is not supported on Quantum Spark appliances, which are designed for small and medium businesses. It is also not supported on Open Server platforms, which are general-purpose servers that run Check Point software on top of third-party operating systems.

Dynamic Dispatch is a feature that enhances CoreXL performance by dynamically assigning new connections to CoreXL FW instances based on their CPU utilization1. To enable Dynamic Dispatch on Security Gateway without enabling Firewall Priority Queues (FPQ), you need to run the command fw ctl multik set_mode 4 in Expert mode and reboot2. This command will set the CoreXL mode to Dynamic Dispatcher without FPQ. The other options are not correct because:

• A. fw ctl Dyn_Dispatch on: This command does not exist and will return an error message.
• B. fw ctl Dyn_Dispatch enable: This command does not exist and will return an error message.
• D. fw ctl multik set_mode 1: This command will set the CoreXL mode to Static Dispatcher without FPQ, which is the default mode2. This mode will use a static hash function to assign new connections to CoreXL FW instances based on their IP addresses and protocol.

 Session Rate Acceleration is a SecureXL feature that accelerates the establishment of new connections by bypassing the inspection of the first packet of each session. Session Rate Acceleration ignores the source port information of the packet, as well as the destination port ranges, protocol type, and VPN information. The other packet info is used by Packet Acceleration, which is another SecureXL feature that accelerates the forwarding of subsequent packets of an established connection. References: SecureXL Mechanism
