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. |
