CCNA: Cisco Certified Network Associate — Question 345

Which network action occurs within the data plane?

Answer options

• A. reply to an incoming ICMP echo request
• B. make a configuration change from an incoming NETCONF RPC
• C. run routing protocols (OSPF, EIGRP, RIP, BGP)
• D. compare the destination IP address to the IP routing table

Correct answer: D

Explanation

The correct answer is D, as the data plane is responsible for the actual forwarding of packets, which includes comparing the destination IP address to the routing table. Options A and B involve control plane functions, such as responding to requests or making configuration changes, while option C refers to routing protocol operations, which also occur in the control plane.
