Question

Southbound protocols, which connect to a network's physical devices, are typically linked to the SDN controller by using a ____.

a) Directory
b) Repository
c) Registry
d) Catalog

Answer 1

Southbound protocols in SDN use a registry to connect to the network's physical devices, which helps in the efficient network resource management.

Step-by-step explanation:

Southbound protocols in a Software Defined Networking (SDN) context refer to the interfaces and protocols used by an SDN controller to communicate with the physical devices in a network, like switches and routers. The correct answer to the question is that these Southbound protocols typically connect to a network's physical devices using a registry. A registry in SDN is used to keep track of various resources within the network, enabling efficient communication and management functions by the SDN controller.
