Answer and Explanation:

Messages flow across an SDN controller's:  

Northbound APIs:  

• Messages which help in read/write state of the network and developing flow tables within the  

state management layer.  

• Notifications for the state-change events.  

• The interaction between the controller and network control applications is done through the  

northbound interface.  

• Network control applications send messages to the controller.  

Southbound APIs:  

• Messages which help for the up-to-date view of the network's state like message for the  

attached link has gone up or down, new devices are joined the network, or indications of the  

device is up or down.  

• Controller's southbound interface is the communication among the controller and the controlled  

devices. Controlled devices are the recipients of the messages sent form the controller.

vekshin1

Answer:

The answer is "Option A and Option C".

Explanation:

In choice a, it is true since a client-server design can be used for REST-application. A user is somebody who needs space and it doesn't deal with storing data on a central computer. A client is someone with the money, and the interface does not. Its server doesn't want to worry regarding core functionality on the ends of the server. The server does not have to know anything at all about the layer of UI used at the end of the server.

In choice c, it is true As just a Web app, services like corporate/employee resources must be organized, and HTTP verbs like the GET, Place, POST, DELETE must be used to modify these. It must be obvious, as a programmer, that what is required is clearly to look only at the interface or HTTP method used.
