   A network engineer is troubleshooting an ONIE automatic installation failure. The switch boots into ONIE and gets an IP address from DHCP. The DHCP server is configured with both option 66 and option 114. Option 66 points to a TFTP server that is offline. Option 114 points to a valid HTTP server with the correct image. The installation fails. What is the most likely reason?

   • AONIE requires both TFTP and HTTP servers to be reachable.
   • BThe DHCP server cannot send both option 66 and option 114 simultaneously.
   • CONIE prioritizes option 66 over option 114 and tries the offline TFTP server first.
   • DThe switch is ignoring option 114 because option 66 is present.

   An administrator is hosting a SONiC image for ONIE automatic installation. The image file is named 'sonic-202406.bin'. The administrator places it on an HTTP server and configures DHCP option 114 to point to http://192.168.1.10/sonic-202406.bin. The installation fails because ONIE cannot find the file. The administrator confirms the file exists at the correct path. What is the most likely cause?

   • AThe HTTP server's document root is not set to the directory containing the file.
   • BThe file name contains a hyphen, which ONIE does not support.
   • CThe image must be renamed to 'onie-installer.bin'.
   • DThe DHCP option 114 must use the IP address instead of the hostname.
