In an SDN architecture, which function of a network node is centralized on a controller?

A. Creates the IP routing table

B. Discards a message due filtering

C. Makes a routing decision

D. Provides protocol access for remote access devices








 

Suggested Answer: C

Community Answer: A

A controller, or SDN controller, centralizes the control of the networking devices. The degree of control, and the type of control, varies widely. For instance, the controller can perform all control plane functions (such as making routing decisions) replacing the devices' distributed control plane.
