Final answer:
The data plane provides A. network processing, security processing, and logging as its data processing features, handling, securing, and tracking the data packets that travel through a network.
Step-by-step explanation:
The three data processing features that the data plane provides are network processing, security processing, and logging. Network processing involves the handling of data packets as they move through the network, including making decisions on where to send them next. Security processing refers to the application of security mechanisms such as access control lists (ACLs), and intrusion prevention systems (IPS) which can include signature matching to identify and mitigate threats. Finally, logging is capturing the details of the transactions or events that take place within the network infrastructure for monitoring or forensic purposes.
