A client creates a packet to send to a server. The client is requesting POP3 service. What number will be used as the destination port number in the sending packet?

  • 110
  • 67
  • 53
  • 69
Explanation & Hint:

POP3, or Post Office Protocol version 3, typically uses port 110. This protocol is used by email clients to retrieve emails from a server.

So, when a client creates a packet to send to a server requesting POP3 service, the destination port number used in the sending packet will be 110.
