Explanation

Single Pass Architecture (Answer C): Palo Alto Networks firewalls use Single Pass Architecture, meaning the firewall processes traffic once for all enabled security services. This avoids duplicating inspection processes for multiple services like Threat Prevention, URL Filtering, and WildFire. With a single traffic inspection pass, the firewall applies all security policies without degrading performance, even as additional CDSS subscriptions are enabled. Management Data Plane Separation (Answer D): The Management Plane and Data Plane are separated on Palo Alto Networks firewalls. The Management Plane handles configuration, logging, and other administrative tasks, while the Data Plane focuses solely on processing and forwarding traffic. This architectural design ensures that enabling additional Cloud-Delivered Security Services does not impact throughput or compromise traffic handling efficiency.
