Refer to the exhibit. What is the effect of the configuration that is shown?
- It configures SSH globally for all logins.
- It tells the router or switch to try to establish an SSh connection first and if that fails to use Telnet.
- It configures the virtual terminal lines with the password 030752180500.
- It configures a Cisco network device to use the SSH protocol on incoming communications via the virtual terminal ports.

Explanation: Secure Shell (SSH) is a protocol Which provides a secure remote access connection to network devices.
Communication between the client and server is encrypted in both SSH version 1 and SSH version 2. If you want to prevent non-SSH connections, add the “transport input ssh” command under the lines to limit the router to SSH connections only. Straight (non-SSH) Telnets are refused.
