When a network administrator is attempting an SSH connection to the device, in which order does the device check the login credentials?
| A. |
RADIUS server, local username, line password | |
| B. |
RADIUS server, line password, local username | |
| C. |
Line password, local username, RADIUS server | |
| D. |
Line password, RADIUS server, local username |
Sessions use the vty lines, where the configured authentication method is named “default.” The AAA default login preference is stated in order from first to last, so here the aaa authentication login default group radius local line means to use RADIUS first, then if that fails use the local user database. Finally, if that fails use the line password.
