Exam 200-301 topic 1 question 164 discussion

Explanation: The data plane, also known as the forwarding plane, is responsible for the actual forwarding of data packets within a network. The key function of the data plane is to forward packets from the source to the destination based on the information in the forwarding table or forwarding information base (FIB). This involves making decisions on how to move the data through the network and ultimately forwarding it to the next hop in the network path. Options A, B, and C are typically associated with the control plane: A. Originating packets: This is a function of the control plane, where devices create or generate packets. B. Exchanging routing table data: This is also a function of the control plane, where devices share routing information to build and update their routing tables. C. Making routing decisions: This is a control plane function where decisions are made on how to route traffic based on the information gathered through routing protocols.

I think 'A. originating packets' is a misleading expression Because the data plane sends packets

D is correct

I remember it by saying " Hop on a (data) plane lol

only answer could be, all other answer relates to control plane

The answer to the question "Which key function is provided by the data plane?" is: D. Forwarding traffic to the next hop The data plane , also known as the forwarding plane, is responsible for the actual forwarding of data packets through a network. It consists of the hardware and software components in a network device that perform packet forwarding, routing, and switching. The data plane makes decisions about where packets should be forwarded to next and determines the appropriate ports to send them out. Therefore, the key function that is provided by the data plane is forwarding traffic to the next hop.
