What is an advantage of using advanced versions of Cloud-Delivered Security Services (CDSS) subscriptions compared to legacy versions of CDSS?

Comprehensive and Detailed In-Depth Step-by-Step Explanation : Cloud-Delivered Security Services (CDSS) are subscription-based services that enhance the capabilities of Palo Alto Networks firewalls, including VM-Series, CN-Series, and Cloud NGFW. The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation highlights the evolution of CDSS, with advanced versions offering significant improvements over legacy versions. Threats are detected with inline cloud-scale machine learning (ML) (Option A): Advanced CDSS subscriptions leverage inline cloud-scale machine learning to detect and prevent threats in real time. This capability provides superior threat detection compared to legacy versions, which relied on traditional signature- based methods without the same level of ML-driven analysis. This is a key differentiator and advantage of the advanced CDSS offerings. Options B, C, and D are incorrect. While new threat-related signature databases (Option B) and external dynamic lists (Option C) are features of CDSS, they are not unique to advanced versions and are available in legacy versions as well. Firewall throughput improvement by inspecting hashes of advanced packet headers (Option D) is not a documented advantage of advanced CDSS and does not align with the primary benefits outlined in the documentation.
