4.1-4. What type of control plane?  We've seen that there are two approaches towards implementing the network control plane - a per-router control-plane approach and a software-defined networking (SDN) control-plane approach.  Which of the following actions occur in a per-router control-plane approach? The other actions that you don't select below then correspond to actions in an SDN control plane.  Group of answer choicesAll routers in the network send information about their incoming and outgoing links to a logically centralized controller.A router exchanges messages with another router, indicating the cost for it (the sending router) to reach a destination host.A control agent in router receives a complete forwarding table, which it installs anduses to locally control datagram forwarding.Routers send information about their incoming and outgoing links to other routers in the network.

2. Which one of the following is not a function of network layer?ld) error controla) routing b) inter-networking c) congestion control

With respect to Software Defined Networking (SDN), which among the following is true? a. SDN couples the data plane and control plane. b. SDN has no relation to either data plane or control plane c. SDN separates the data plane and control plane. d. None of the stated.
