Exam 350-401 topic 1 question 54 discussion

vBond plays a crucial role and acts as a Session Traversal Utilities for NAT (STUN) server, which allows other controllers and SD-WAN routers to discover their own mapped/translated IP addresses and port numbers. SD-WAN devices advertise this information along with their TLOCs so other SD-WAN devices have information in order to make successful connections. https://www.cisco.com/c/en/us/td/docs/solutions/CVD/SDWAN/cisco-sdwan-design-guide.html

i dont know what STUN is, but when i see "onboarding" i click vBond.

cisco cd-wan seems to change a lot, do we still have to study these or check new documents?

A is correct The vBond orchestrator is responsible for orchestrating the initial bring-up process of edge devices, including authentication, authorization, and assigning control plane roles. It also acts as a STUN server to facilitate NAT traversal during the onboarding process, enabling secure communication between the edge devices and the SD-WAN fabric.

The SD-WAN Validator (Former name vBond) plays a crucial role and acts as a Session Traversal Utilities for NAT (STUN) server, which allows other control components and SD-WAN routers to discover their own mapped/translated IP addresses and port numbers.

Cisco vBond plays a crucial role and acts as a Session Traversal Utilities for NAT (STUN) server, which allows other controllers and Cisco SD-WAN routers to discover their own mapped and translated IP addresses and port numbers. Cisco SD-WAN devices advertise this information along with their TLOCs, so other Cisco SD-WAN devices have information to make successful connections.

The Cisco SD-WAN solution is comprised of separate orchestration, management, control and data plane. • Orchestration plane assists in securely onboarding the SD-WAN WAN Edge routers into the SD-WAN overlay. The vBond controller, or orchestrator, authenticates and authorizes the SD-WAN components onto the network. The vBond orchestrator takes an added responsibility to distribute the list of vSmart and vManage controller information to the WAN Edge routers.
