SecureXL full acceleration happens on which component?

The correct answer is B. snd . In Check Point performance architecture, SND means Secure Network Distributor . It is the CoreXL component that receives traffic from network interfaces, performs SecureXL acceleration where possible, and distributes non-accelerated traffic to CoreXL Firewall instances for deeper inspection. Check Point’s Performance Tuning documentation describes CoreXL SND as responsible for processing incoming traffic, securely accelerating authorized packets when SecureXL is enabled, and distributing non-accelerated packets between Firewall kernel instances.

This explains why SND is the correct answer for SecureXL full acceleration. The accelerated path is handled before the traffic is passed into a full firewall inspection path. IRQ is an interrupt mechanism, not the logical acceleration component. A CPU core provides processing capacity, but it is not the named SecureXL acceleration component. The dynamic dispatcher is related to distributing traffic among CoreXL Firewall instances based on load; it is not where SecureXL full acceleration is performed. This distinction matters heavily in performance troubleshooting: high SND utilization, traffic falling to F2F, or excessive PXL/FWK handling can indicate that Threat Prevention inspection is preventing full acceleration.
