• NETCONF

• REST API

What are two improvements provided by automation for network management in an SDN environment? (Choose two)

• Artificial intelligence identifies and prevents potential design failures

• Data collection and analysis tools establish a baseline for the network

• New devices are onboarded with minimal effort

• Machine learning minimizes the overall error rate when automating troubleshooting processes

• Proprietary Cisco APIs leverage multiple network management tools

What is the function of a controller in controller-based networking?

• It is a pair of core routers that maintain all routing decisions for a campus

• It centralizes the data plane for the network

• It is the card on a core router that maintains all routing decisions for a campus

• It serves as the centralized management point of an SDN architecture

Where is the interface between the control plane and data plane within the software-defined architecture?

• application layer and the management layer

• application layer and the infrastructure layer

• control layer and the application layer

• control layer and the infrastructure layer

Which plane is centralized by an SDN controller?

• data plane

• management plane

• control plane

• services plane

Which communication interaction takes place when a southbound API is used?

• between the SDN controller and PCs on the network

• between the SDN controller and switches and routers on the network

• between the SDN controller and services and applications on the network

• between network applications and switches and routers on the network

Which type of API allows SDN controllers to dynamically make changes to the network?

• northbound API

• southbound API

• SOAP API

• REST API

What is the function of "off-the-shelf" switches in a controller-based network?

• Forwarding packets

• Making routing decision

• Providing a central view of the deployed network

• Setting packet-handling policies
