Exam 350-401 topic 1 question 486 discussion

Orchestration plane (vBond) assists in securely onboarding the SD-WAN WAN Edge routers into the SD-WAN overlay. References: https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/SDWAN/sdwan-wan-edge-onboarding-deploy-guide-2020nov.pdf

C is correct. vBond = onboarding without reading the rest :D

Answer is C... VBond onboards the device into the overlay. It authenticates the devices onto the fabric. even from PnP portal... thats the purpose of the vBond. If you answer A you will be sorry.

Answer "A" "initiating connections with SD-WAN routers automatically" is wrong and here is why: Page 36 of Cisco SDWAN Ciscopress book, states that "The WAN Edge will attempt to build a temporary connection to the vBond..." So it is the WAN Edge (AKA SD-WAN router) that initiates the connection to vBond. vBond does not sit there looking to initiate connections with SD-WAN routers, the SD-WAN router needs to reach out first, and then vBond provides the SD-WAN the information that it needs, such as vManage and vSmart IPs.

Answer A is correct. vBond – initiates the bring up process of every vEdge device. https://www.google.com/search?q=What+is+the+function+of+vBond+in+a+Cisco+SD-WAN+deployment%3F&rlz=1C1GCEA_enAU912AU912&oq=What+is+the+function+of+vBond+in+a+Cisco+SD-WAN+deployment%3F&aqs=chrome..69i57j0i30.910508327j0j15&sourceid=chrome&ie=UTF-8

vBond is correct

vBond gives the IP of the vManage, in the initial transient connection. The vManage sends the config (onboarding) to the vEdge.

Going for A. It comes closest to what vBond is doing reading through all the linked documents here. I don't think it is C. vBonds function is not to onboard. It is only giving the IP of the vManage Server to the Router (and this can be done automatically). vManage is onboarding the routers.

C (vBond not initia connection to vEdges automatically ) WAN Edge onboarding process Upon bootup, the WAN Edge device contacts the vBond orchestrator to establish a secure transient DTLS control connection. Reference (Page 6): https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/SDWAN/sdwan-wan-edge-onboarding-deploy-guide-2020nov.pdf

I think answer here is still A. The vBond only assists in the onboarding, it is not responsible for onboarding, that is completed by vManage. The part vBond plys in the onboarding is to automatically initiate the connection with the WAN edge routers, authenticate them and provide them with a list of vManage and vSmart devices

C - initial comms started by vedge to vbond, not by vbond.

Answer is C

it is answer C

It onboards Edge routers, see: https://www.cisco.com/c/en/us/td/docs/solutions/CVD/SDWAN/cisco-sdwan-design-guide.html#OrchestrationPlane
