Why each option
This question asks for the correct Cisco SD-WAN command syntax to configure a 1 Mbps shaping rate on a WAN link of a WAN Edge router.
This option reverses the typical order of `vpn` and `interface` for this type of configuration, making it syntactically incorrect.
In Cisco SD-WAN, interface-specific configurations like shaping rate are applied within the VPN context using the `vpn vpn-id interface interface-name` structure. Shaping rates are specified in kilobits per second (Kbps), so 1 Mbps is correctly expressed as 1000 Kbps. Thus, `vpn vpn-id interface interface-name shaping-rate 1000` is the correct command.
