A. B. C. D.A
The forwarding plane, also known as the data plane or the forwarding engine, is responsible for the actual forwarding of packets through the network device. It is one of the two main components of a network device, the other being the control plane.
Regarding the given statements, the correct option is A: "It uses ASICs for increased performance." ASICs (Application-Specific Integrated Circuits) are specialized hardware chips designed for specific tasks. In the case of the forwarding plane, ASICs are used to accelerate packet processing and forwarding, which leads to higher performance and lower latency.
Option B: "It is the intelligence of the platform" is incorrect. While the forwarding plane is responsible for forwarding packets, it does not make any decisions about the network topology, routing, or other intelligence-related tasks. Those are handled by the control plane.
Option C: "It maintains the routing tables" is also incorrect. The routing tables are managed by the control plane, which is responsible for the overall control and management of the device.
Option D: "It is based on an x86 architecture" is incorrect. x86 architecture refers to the instruction set used by certain types of processors, such as Intel or AMD processors. While some network devices use x86 processors for their control planes, the forwarding plane typically uses specialized hardware, such as ASICs, as mentioned earlier.
