Which of these actions is performed in the device data plane?

The data plane (or forwarding plane) is responsible for forwarding user traffic. When a packet arrives, the device compares its destination IP address to the IP routing table to determine the next hop, which is a data plane function. Incorrect options: Replying to an incoming ICMP echo request is a control plane function, as it involves the device itself generating a response rather than simply forwarding user data. Making a configuration change from an incoming NETCONF RPC is a management plane function, as it deals with device configuration and administration. Running routing protocols (OSPF, EIGRP, RIP, BGP) are control plane functions. These protocols build and maintain the routing table, which is then used by the data plane for forwarding decisions.
