Why each option
Single Pass Parallel Processing (SP3) is a core architectural innovation in Palo Alto Networks firewalls that enables high-performance, integrated security scanning of all traffic with minimal buffering.
True. The Single Pass Parallel Processing (SP3) architecture is designed to perform multiple security functions simultaneously on a single pass of traffic, including App-ID, Content-ID (IPS, antivirus, anti-spyware, WildFire), and URL filtering. This approach minimizes buffering and latency, allowing advanced threat prevention features to operate at high speed without significantly degrading firewall performance.
False. SP3 architecture specifically addresses the performance challenges of integrating multiple security services by optimizing the inspection process, directly enabling advanced scanning capabilities with minimal performance impact.
