Refer to the exhibit. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed configuration to satisfy the requirement?
- Use SSH version 1.
- Reconfigure the RSA key.
- Configure SSH on a different line.
- Modify the transport input command.
Answers Explanation & Hints: The network administrator should modify the transport input command to allow SSH connections and prohibit Telnet connections. Currently, the transport input command is set to “transport input telnet”, which allows Telnet connections. To allow SSH connections and prohibit Telnet connections, the command should be changed to “transport input ssh”. The modified configuration for Switch1 should be as follows:
Switch1(config)# line vty 0 15
Switch1(config-line)# transport input ssh
This configuration change will allow only SSH connections to the VTY lines on Switch1.
