A client creates a packet to send to a server. The client is requesting telnet service. What number will be used as the destination port number in the sending packet?

  • 23
  • 443
  • 161
  • 110
Explanation & Hint:

Telnet, a protocol used for accessing remote computers, typically uses port 23. This port is the standard TCP port for telnet connections and is used for telnet sessions that involve a user connecting to a remote host or server.

So, when a client creates a packet to send to a server requesting telnet service, the destination port number used in the sending packet will be 23.
