Which key function is provided by the data plane? (CCNA 200-301)
Which key function is provided by the data plane?
A. Originating packets
B. Exchanging routing table data
C. Making routing decisions
D. Forwarding traffic to the next hop
Solution
Correct answer: D. Forwarding traffic to the next hop.
The data plane is responsible for forwarding traffic through a network device, such as a router or switch. It receives incoming packets, examines their headers, and forwards them to the next hop on the path to their destination. This is the primary function of the data plane.
The other options are incorrect because:
A. Originating packets is a function of the control plane, which is responsible for generating and sending packets.
B. Exchanging routing table data is a function of the control plane, which is responsible for exchanging routing information with other network devices.
C. Making routing decisions is a function of the control plane, which is responsible for determining the best path for forwarding packets.
