Correct answer is C,
https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/system-interface/vedge-20-x/systems-interfaces-book/configure-devices.html in this document it states in section Upload WAN Edge Router Authorized Serial Number File
To upload the WAN edge router authorized serial number file to Cisco vManage and then download it to controllers in the network:
From the Cisco vManage menu, choose Configuration > Devices.
Click WAN Edge List, and click Upload WAN Edge List.
Under Upload WAN Edge List screen:
Click Choose File and select the WAN edge router authorized serial number file you received from Cisco PnP.
To automatically validate the routers and send their chassis and serial numbers to the controllers, ensure that the Validate the uploaded vEdge List and send to controllers check box is selected. If you do not select this option, you must individually validate each router in Configuration > Certificates > WAN Edge List.
Click Upload.
A list of routers in the network is displayed in the router table, with details about each router.
Option C is correct. Initially by reading the question, option D looks very likely. But after reading it multiple times with more attention, Option C comes out as a correct answer.
vManage version 20.9
Configuration > Devices > Upload WAN Edge List
Validate the uploaded vEdge List and send to controllers (there's only one option, not two)
To fully onboard the device, the
device state must be moved from staging to valid. In vManage under Configuration > Certificates > WAN Edge List,
select the WAN Edge device(s) and change the state to valid under the Validity column and click Send to Controllers.
It's a poorly written question, because C and D are both required steps. Sending the list to the vSmart controllers is necessary, but it can be done without onboarding the devices at this time. Setting the devices as valid is what tells the vSmart to onboard those devices as soon as they come online.
C. Set the device as valid (to !!!support!!! the on-boarding process !!!before!!! the device comes online"). See the document linked below by CCNPCollab1297.
https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/SDWAN/sdwan-wan-edge-onboarding-deploy-guide-2020nov.pdf :
Technical Tip: A WAN Edge device within staging state will establish only control connections with the SD-WAN controllers. No data plane connections are established across WAN Edge devices. To fully onboard the device, the device state must be moved from staging to valid. In vManage under Configuration > Certificates > WAN Edge List, select the WAN Edge device(s) and change the state to valid under the Validity column and click Send to Controllers.
D
Question says: "to !!!support!!! the on-boarding process !!!before!!! the device comes online".
'Support' and 'before online' says to us that device must be staged, since it is not online (doesn't send traffic), but we must control it (hence, support it).
We can do that if we stage device and send list to controllers.
When we validate device, it comes online (and question says before it comes online).
It is asking for a configuration task on vManage, so that would be C
The whitelist will be shared automatically with other controllers. No need to configure anything for that.
WAN Edge devices have to be known and authorized by all the SD-WAN controllers before allowing the device onto the network. D seems to be correct for me.
Yes you are right, but they need to be validated before, you can use the checkbox when uploading the list into the vManage, or you go to devices and validate them one by one and then you will share the valid list to the controllers. That is why when you do a show valid-vedges on the vSmart you will only see the ones that are valid and no the whole list.
