Which two methods add a WAN Edge router's certificate serial number to vManage's Authorized Serial Number list? (Choose two.)

To add a WAN Edge router's certificate serial number to vManage's authorized list, you can either synchronize it with the Smart Account or manually upload it. Synchronizing with the Smart Account is a common method for automated onboarding, where the serial numbers are pulled from your Cisco Smart Account. Manually uploading the serial number allows for direct entry into vManage, useful for specific deployments or troubleshooting. The PnP (Plug and Play) portal is used for device onboarding but doesn't directly add serial numbers to vManage's authorized list; it facilitates the device's connection to the SD-WAN fabric. vManage is not shipped with a pre-populated list of all possible serial numbers. Devices register to vManage after their serial numbers are authorized, not as the primary method of authorization.
