   A junior admin creates an API token in the Mist portal with 'Read' scope to automate switch status checks. When the admin runs a script that calls POST /api/v1/sites/{site_id}/devices/{device_id}/reboot, the API returns HTTP 403. What is the most likely cause?

   • AThe switch is offline, so the API refuses to accept the reboot command.
   • BThe API token has expired and must be regenerated in the Mist portal.
   • CThe site ID in the URL is incorrect, causing the API to reject the request.
   • DThe API token lacks write permission, so the reboot operation is denied.
