What are two characteristics of vManage APIs? (Choose two.)
vManage APIs have distinct characteristics based on their functional direction relative to the management system. The Northbound API is used for integrating with external systems and is RESTful using JSON, which allows for easy interaction and integration with web services and applications. The Southbound API, on the other hand, leverages NETCONF and XML to communicate with and manage network devices, providing a robust and standardized way to handle configurations and operational commands.
"vManage is the management plane for the overall SDWAN solution. It uses netconf/YANG to talk to vEdge devices"
Answer is correct, Northbound = RESTful, Southbound = NETCONF https://www.ciscolive.com/c/dam/r/ciscolive/emea/docs/2020/pdf/DEVNET-1380.pdf
*vSmart* uses OMP and DTLS for communication with edge devices. *vManage* uses NetConf according to Cisco's presentation (above linked pdf) on this very topic: vManage REST APIs • vManage uses REST architecture which is stateless, client–server, cacheable communications protocol. • vManage exposes REST APIs and webhooks to integrate with 3rd party systems • vManage uses NetConf for configuring and managing edge devices
B & E are correct The Network Configuration Protocol (NetConf) uses an Extensible Markup Language (XML) to communicate with the switches and routers to install and make configuration changes. NETCONF is an XML-based protocol used for configuration and monitoring devices in the network. https://www.sdxcentral.com/networking/sdn/definitions/what-the-definition-of-software-defined-networking-sdn/southbound-interface-api/#:~:text=The%20Network%20Configuration%20Protocol%20(NetConf)%20uses%20an%20Extensible%20Markup%20Language%20(XML)%20to%20communicate%20with%20the%20switches%20and%20routers%20to%20install%20and%20make%20configuration%20changes https://docs.opendaylight.org/projects/netconf/en/latest/user-guide.html#:~:text=NETCONF%20is%20an%20XML%2Dbased%20protocol%20used%20for%20configuration%20and%20monitoring%20devices%20in%20the%20network.
The correct options are: A. Northbound API is based on RESTCONF and JSON. E. Northbound API is RESTful using JSON. Both of these options correctly describe the characteristics of the vManage's Northbound API. Thank you for your understanding, Nuno!
DE OMP and DTLS are the protocols used by vManage API to communicate with the Cisco devices
