CCNA: Cisco Certified Network Associate — Question 279

Which networking function occurs on the data plane?

Answer options

• A. processing inbound SSH management traffic
• B. sending and receiving OSPF Hello packets
• C. facilitates spanning-tree elections
• D. forwarding remote client/server traffic

Correct answer: D

Explanation

The correct answer is D because forwarding remote client/server traffic is a primary function of the data plane, which is responsible for the actual movement of packets. Options A, B, and C relate to control plane functions, which manage and facilitate the flow of data rather than forwarding it.
