Correct answer: Forwarding traffic to the next hop.
Why this is the answer
The data plane (also known as the forwarding plane) is responsible for the actual movement of data packets through a network device. Its primary function is to forward traffic to the next hop based on the information provided by the control plane. This involves encapsulating/decapsulating packets, performing checksums, and applying QoS policies. Originating packets is typically a function of end devices or applications, not the network device's data plane. Exchanging routing table data and making routing decisions are functions of the control plane. The control plane builds and maintains the routing table, which the data plane then uses to determine the appropriate next hop for forwarding.
