Exam 200-301 topic 1 question 108 discussion

The function of a controller in controller-based networking is A. It serves as the centralized management point of an SDN (Software-Defined Networking) architecture . The controller is responsible for managing network devices and implementing network policies, as well as providing a central point of control and visibility for the entire network. It enables dynamic, programmatically efficient network configuration through the use of software-based controllers or a centralized controller with open APIs (Application Programming Interfaces) that communicate with network devices and applications . This promotes increased network agility, scalability, and flexibility in response to changing business needs.

A is correct.

A is correct

In the context of the question, both options B and C are valid functions of an endpoint, but option B describes a broader function—connecting server and client devices to a network—which encompasses the role of endpoints in facilitating communication between various devices on the network.

Answer A is correct because a controller, or SDN controller, centralizes the control of the networking devices. https://www.ciscopress.com/articles/article.asp?p=2995354&seqNum=2#:~:text=A%20controller%2C%20or%20SDN%20controller,the%20devices'%20distributed%20control%20plane.
