   An administrator is setting up ONIE automatic installation for a fleet of switches. The SONiC image is stored on an HTTP server as /images/sonic-202406.bin. The DHCP server is configured to hand out option 114 with the value http://10.0.0.10/images/sonic-202406.bin. When a switch boots, it downloads the image but fails with a '404 Not Found' error. The HTTP server is reachable from the switch. What is the most likely cause?

   • AThe DHCP option 114 value must be a TFTP URL, not an HTTP URL.
   • BThe switch does not have a default gateway, so it cannot reach the HTTP server.
   • CThe web server's document root is not set to the directory containing the image.
   • DONIE requires the image to be named 'sonic.bin' exactly.
