Question:
What is one difference between using Telnet or SSH to connect to a network device for management purposes?

• Telnet uses UDP as the transport protocol whereas SSH uses TCP.
• Telnet does not provide authentication whereas SSH provides authentication.
• Telnet supports a host GUI whereas SSH only supports a host CLI.
• Telnet sends a username and password in plain text, whereas SSH encrypts the username and password

Explanation: SSH provides security for remote management connections to a network device. SSH does so through encryption for session authentication (username and password) as well as for data transmission. Telnet sends a username and password in plain text, which can be targeted to obtain the username and password through data capture. Both Telnet and SSH use TCP, support authentication, and connect to hosts in CLI.
