Palo Alto Networks (PANW) Certified Cybersecurity Entry-level Technician (PCCET) Practice Exam

Palo Alto Networks firewalls are built on which type of architecture?

1. Multi-pass

2. Ultimate-pass

3. Single-pass

4. Strict-pass

The correct answer is: Single-pass

Palo Alto Networks firewalls are built on a single-pass architecture, which is designed to optimize performance and efficiency during traffic inspection. This architecture allows all traffic to pass through a single processing pipeline where it undergoes inspection for security policies, application identification, and threat prevention in one go, rather than passing through multiple engines in succession. This single-pass approach significantly enhances processing speed and reduces latency, as data packets are analyzed and acted upon in a streamlined manner. By handling all necessary tasks in a unified process, Palo Alto firewalls can achieve higher throughput and better resource utilization while effectively managing a wide range of security functions. The effectiveness of this architecture lies in its ability to keep pace with fast-evolving network traffic demands, ensuring that security measures do not introduce bottlenecks that could impact network performance. This design is fundamental to the operation of Palo Alto firewalls and underpins their reputation for providing strong security capabilities without compromising speed.
