Which network action occurs within the data plane? (CCNA 200-301)
Which network action occurs within the data plane?
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.
Solution
Correct answer: D. compare the destination IP address to the IP routing table.
Explanation:
A. Replying to an incoming ICMP echo request involves control plane functions, such as processing the ICMP packet and generating the response.
B. Making a configuration change from an incoming NETCONF RPC is a control plane function, as it involves modifying the device's configuration.
C. Running routing protocols like OSPF, EIGRP, RIP, and BGP is a control plane function, as it involves exchanging routing information and updating the routing table.
D. Comparing the destination IP address to the IP routing table is a data plane function, as it involves the forwarding of data packets based on the routing information in the table.
The data plane is responsible for the actual forwarding and processing of data traffic, while the control plane handles the management and configuration of the network.
