A client packet is received by a server. The packet has a destination port number of 69. What service is the client requesting?

  • DHCP
  • SMTP
  • TFTP
  • DNS
Explanation & Hint:

The client is requesting the TFTP (Trivial File Transfer Protocol) service. In networking, port numbers are used to identify specific services or protocols, and port number 69 is designated for TFTP.

TFTP is a simple protocol to transfer files, and it is used where the simplicity of implementation is more critical than the advanced features of a more robust file transfer protocol like FTP. It is commonly used for transferring small files such as system boot files or configurations over a network.
