Exam CCSP topic 1 question 175 discussion

D is incorrect, A: Routing is correct, Routing is taken over the management plane!!! SDN contains a Management Plane & a Forwarding Plane, in the second one goes as well the Filtering The concept of Software Defined Networking (SDN) is about taking the routing control away from the individual network elements, and putting it in the hands of a centralized control layer - for example Nevion VideoIPath orchestration and SDN control system. https://techex.co.uk/ip-production/software-defined-network-sdn-routing#:~:text=Software%20Defined%20Network%20%28SDN%29%20routing%20The%20concept%20of,example%20Nevion%20VideoIPath%20orchestration%20and%20SDN%20control%20system.

So the correct interpretation for the question could be that SDN abstracts filtering from the traffic forwarding process. The controller decides which traffic should be allowed, blocked, or redirected (filtering), and the network devices apply these instructions while forwarding the traffic.

should be A

n traditional networking, routing decisions are typically made within network devices such as routers, which determine the path for traffic to reach its destination based on various routing protocols and algorithms. In SDN, the control plane, managed by a centralized controller, abstracts the routing functionality. It is responsible for making routing decisions and programming the forwarding behavior of network devices.

should be A

Answer is A:Routing.

filtering traffic C

networking is abstracted from the forwarding of traffic. Keyword is abstracted here. Thus, the answer will be filtering.

Should be routing

At first I thought this was routing, but we are not routing traffic. We are forwarding so we are filtering this to a destination or port.
