CoreXL is a performance-enhancing technology that enables the processing CPU cores to concurrently perform multiple tasks on Security Gateways with multiple CPU cores. CoreXL replicates the Firewall kernel multiple times, creating multiple Firewall instances that run on different CPU cores. These Firewall instances handle traffic concurrently, and each Firewall instance is a complete and independent Firewall inspection kernel. To show the current connections distributed by CoreXL FW instances, you can use the command fw ctl multik stat on the Security Gateway. This command will display information such as the number of connections, packets, bytes, drops, and errors handled by each CoreXL FW instance, as well as the CPU utilization and affinity of each instance. The other options are not correct because:

• B. fw ctl affinity -l: This command will show the CPU affinity of all processes and IRQs on the Security Gateway. It will not show the current connections distributed by CoreXL FW instances.
• C. fw ctl instances -v: This command will show the details of all CoreXL FW instances on the Security Gateway, such as their ID, type, state, priority, and interfaces. It will not show the current connections distributed by CoreXL FW instances.
• D. fw ctl iflist: This command will show the list of all interfaces on the Security Gateway, along with their names

According to the Check Point website, SmartUpdate is the application that should be used to install a contract file. A contract file contains information about the licenses and services that are purchased from Check Point. SmartUpdate can also be used to install software packages and patches on Security Gateways and Management Servers. The other applications are either not relevant or not capable of installing a contract file. References: SmartUpdate

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.
