Which action is taken by the data plane within a network device? (CCNA 200-301)
Which action is taken by the data plane within a network device?
A. Constructs a routing table based on a routing protocol.
B. Forwards traffic to the next hop.
C. Looks up an egress interface in the forwarding information base.
D. Provides CLI access to the network device.
Solution
Correct answer: B. Forwards traffic to the next hop.
The data plane is responsible for forwarding traffic through a network device, such as a router or switch. It examines incoming packets, determines the next hop, and forwards the packets to their destination. This process is typically performed using a forwarding information base (FIB) or a routing table.
The data plane is focused on packet forwarding, whereas the control plane is responsible for tasks such as constructing routing tables (option A) and providing CLI access (option D).
