What is the purpose of a southbound API in a control based networking architecture?
AFacilities communication between the controller and the applications
BFacilities communication between the controller and the networking hardware
Callows application developers to interact with the network
Dintegrates a controller with other automation and orchestration tools.
Correct Answer:B
The Southbound Interface In a controller-based network architecture, the controller needs to communicate to the networking devices. In most network drawings and architecture drawings, those network devices typically sit below the controller, as shown in Figure 16-5. There is an interface between the controller and those devices, and given its location at the bottom part of drawings, the interface came to be known as the southbound interface, or SBI, as labeled in Figure 16-5.

What causes a port to be placed in the err-disabled state?
Alatency
Bport security violation
Cshutdown command issued on the port
Dnothing plugged into the port
Correct Answer:B
This mode is the default violation mode; when in this mode, the switch will automatically force the switchport into an error disabled (err-disable) state when a violation occurs. While in this state, the switchport forwards no traffic. The switchport can be brought out of this error disabled state by issuing the errdisable recovery cause CLI command or by disabling and reenabling the switchport.
