Exam 350-401 topic 1 question 1008 discussion

vManage interacts with Cisco SD-WAN devices in the fabric using southbound APIs. These APIs facilitate communication and management of the network devices. D. southbound API

Answer is D vManage uses a southbound API to interact with Cisco SD-WAN devices in the fabric. In the context of software-defined networking (SDN) and network management, a southbound API is an interface that enables a controller or management system (like vManage) to communicate with and control the underlying network devices (such as vEdge routers, cEdge routers, and vSmart controllers in the Cisco SD-WAN fabric).

A Northbound API is used to communicate upward from a controller (in this case, vManage) to external applications or systems. A Southbound API is used to communicate downward from a controller to the devices it manages.

I'm going with Northbound APIs. The comments are talking about controllers managing devices, but vSmart is the controller. vManage is the human interface which is "north" of the controllers.

devices -> SB

why not c, north is for upperlayer app, south is vsmart to edge

Southbound API: In the context of Cisco SD-WAN, vManage uses southbound APIs to interact with the SD-WAN devices in the network fabric. Southbound APIs are used by a controller to communicate with the network devices (such as routers and switches) to enforce policies, configure settings, and manage the overall network.

D is correct don't make it complicated about it, controller to devices = South application to the controller: North

Answer is B

Answear is B

Southbound APIs interact with fabric devices. Northbound APIs interact with applicatons.

Answer is B
