   A network engineer is using TFTP to upgrade the IOS on a switch. The switch is in a remote office and the TFTP server is at the head office. The transfer is very slow and eventually times out. What is the most likely cause?

   • BThe TFTP server requires authentication
   • CThe switch does not support TFTP
   • DTFTP uses UDP without congestion control, so packet loss causes retransmissions and timeouts
