Why each option

The data plane of a firewall is dedicated to the high-speed processing of network traffic, encompassing critical functions like network processing and threat signature matching.

Asignature matchingCorrect

Signature matching, such as identifying known threats via Antivirus, Anti-Spyware, and Vulnerability Protection signatures, is a core threat prevention function executed by the data plane as traffic flows through the firewall.

Breporting

Reporting is typically handled by the management plane or a logging/reporting server, which aggregates and presents data collected from the data plane, rather than being a data plane processing feature itself.

Cnetwork processingCorrect

Network processing involves fundamental tasks like routing, NAT, session management, and forwarding packets, which are high-performance data plane operations essential to ensure traffic reaches its destination.

Dlogging

While the data plane generates logs, the process of collecting, storing, and presenting these logs is primarily a function of the management plane or a dedicated logging infrastructure, not a direct data processing feature of the data plane.
