An administrator wishes to force remote access users to connect using SSH. Which command must be entered to disable Telnet access and force SSH use?

A. The no telnet Global Configuration command

B. no telnet in vty Line Configuration mode

C. The transport input ssh Global Configuration command

D. transport input ssh in vty Line Configuration mode

Solution

D is correct. This is the correct command, and must be entered in Line Configuration mode.

A, B, and C are incorrect. A and B are incorrect because no telnet is not a valid IOS command. C is incorrect because it is the correct command, but it’s in the wrong configuration mode.
