An organization wants to deploy applications that can programmatically alter network behavior. In addition, they want to deploy additional network services in real-time.
Which cloud-management component should be included in the design to support this requirement?
A. Hypervisor Element Manager
B. Software-Defined Network Controller
C. Network Management Controller
D. Virtual Switch Manager
Correct Answer: B
Explanation/Reference:
An SDN controller is an application in software-defined networking (SDN) that manages flow control to enable intelligent networking. SDN controllers are based on protocols, such as OpenFlow, that allow servers to tell switches where to send packets.
In effect, the SDN controller serves as a sort of operating system (OS) for the network. By taking the control plane off the network hardware and running it as software instead, the controller facilitates automated network management and makes it easier to integrate and administer business applications.
