Why each option
This question asks to identify two characteristics of vManage APIs, distinguishing between its northbound and southbound interfaces.
The vManage northbound API is generally RESTful using JSON, but not specifically limited to RESTCONF, which is a particular type of REST API often used southbound.
Cisco vManage uses southbound APIs, primarily NETCONF with XML encoding, to communicate with and configure devices like vSmart controllers and WAN Edge routers, ensuring programmatic device configuration.
The vManage southbound API primarily utilizes NETCONF with XML for configuration, not RESTCONF with JSON.
OMP (Overlay Management Protocol) and DTLS (Datagram Transport Layer Security) are fundamental control and data plane protocols within the SD-WAN fabric, not specific API types for vManage's configuration communication.
The northbound API of Cisco vManage is a RESTful API, which allows external systems to programmatically interact with and manage the SD-WAN fabric, commonly utilizing JSON for data exchange due to its flexibility and readability.
