Question 168 - 156-315.81 discussion

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 commandfw ctl multik staton 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
