API = Application Programmable Interface. Yes, it uses the Northbound interface but it is an API that is traveling over the Northbound.

The correct answer is B. application programming interface (API). An application programming interface (API) is a set of rules and protocols that allows different software applications to communicate and interact with each other. In the context of sending data over an IP network from a client to a server, an API provides the necessary methods and functions for the client application to establish a connection, format and send the data packets, and communicate with the server. While northbound and southbound interfaces are also valid terms used in networking, they typically refer to the interfaces used in network management and communication between different layers of a network architecture. The Representational State Transfer (REST) API is a specific type of API that uses HTTP protocols and follows the principles of RESTful architecture for creating web services, but it is not the only type of API that enables data transfer over an IP network.

Not "SDN" or "Controller" in question... so API

API, answer is B

B again.

correct!

A - Northbound interface

IT should be B, guys

why not D - REST API ?

I believe B

Application programming interface (API): This term refers to a set of rules and protocols that allows one software application to communicate with another. In the context of client-server communication over IP, an API would define how applications on the client side can send data to a server over an IP network. Therefore, this is the correct answer. So, the correct answer is B. application programming interface.

I think A is the desired answer. They are asking about the Interface "type".

B is correct

Asked this on Copilot - in ccna sdn Which interface type enables an application running on a client to send data over an IP network to a server? Response In the context of Software-Defined Networking (SDN), the interface type that enables an application running on a client to send data over an IP network to a server is the northbound interface (NBI)1. The NBI allows communication between the SDN controller and external applications, including those running on clients. Through the NBI, applications can configure the SDN controller and retrieve information from it. It acts as a bridge, allowing administrators to interact with the SDN environment and manage network resources effectively.

The interface type that enables an application running on a client to send data over an IP network to a server is typically referred to as a northbound interface. The northbound interface is responsible for communication between the application layer and the network layer, allowing applications to interact with the underlying network infrastructure. So, the correct answer is: A. northbound interface

A northbound interface is a type of interface that allows an application running on a client to send data over an IP network to a server. It is also known as a client-server interface. The application programming interface (API), is a type of interface that allows two or more software components to communicate with each other. It is not specific to client-server communication.

A is the correct answer
