Which characteristic best describes the control plane of a networking device? (Choose three.)
Information sent to this plane is processed by the CPU.
This plane is also called the forwarding plane.
This plane makes forwarding decisions.
This plane contains router protocol neighbor and topology tables.
This plane is responsible for switching frames out the interfaces.
Information sent to this plane is processed by the CPU.
This plane makes forwarding decisions.

Which characteristics best describe the data plane of a networking device? (Choose three.)
This plane is the brains of the device.
This plane is used to forward traffic flows.
Information in this plane is typically processed by a special processor.
This plane contains IPv4 and IPv6 Routing tables.
This plane is typically made up of a switch fabric connecting the various ports on a device.

This is a logical entity that enables network administrators to manage and dictate how the data plane of switches and routers should handle network traffic.
Control plane.
Data plane.
VM.
SDN controller.
SDN controller.

This is a table that matches incoming packets to a particular flow and specifies the functions that are to be performed on the packet.
Neighbor table.
Routing table.
Flow table.
ARP table.
Meter table.
Flow table.
This is a table that triggers a variety of performance-related actions on a flow including the ability to rate-limit the traffic.
