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. |
