Carries the traffic that provides the signals to or from a router. Decides how to move data.

• A. Control Plane
• B. SDN
• C. Directory Services
• D. Cloud to On-Premise Connections

Answer: (A)

The control plane is responsible for signaling and routing decisions that determine how data should be moved through the network. It runs routing protocols, exchanges neighbor and topology information, and builds the routing tables that tell the network where to forward each packet. The data plane is the actual path that packets travel, using the decisions from the control plane to forward traffic. In SDN, this separation is even more explicit: a centralized controller (the control plane) makes the decisions, and the switches (the data plane) implement those forwarding rules. Other options don’t fit because directory services handle identities, while cloud-to-on-premise connections describe a type of link rather than the mechanism that decides packet forwarding.
