A.

B.
It configures a cisco network device to use the SSH protocol on incoming communications via the virtual terminal ports.

C.
It allows seven failed login attempts before the VTY lines are temporarily shutdown.

D.
It configures the virtual terminal lines with the password 030752180500.

E.

Explanation:

Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. Communication between the client and seiver 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.
