You are configuring an authenticated connection between two routers named Tacoma and Lansing. The
connection on the Lansing end is correctly set up with a password of keypass. You are directing an assistant to
configure the name and password on Tacoma.
Which of the following commands would be correct to complete this authenticated connection?

A.
username Tacoma password keypass

B.
username Lansing keypass password

C.
username Tacoma keypass password

D.
username Lansing password keypass

Explanation:
To complete the configuration, you should run the command username Lansing password keypass. This
command creates a user account for the Lansing router with a password of keypass.
When creating an authenticated connection between the routers, a user account must be created for the otherrouter. The password configured must match on both ends.
When examining the output produced by the show running-configuration command for two routers, the output
should read as below:

The lines that display enable password cisco and enable password cisco1 represent local passwords to enable
privileged mode on the local router. These passwords do not have to match. The lines of output that must
display matching passwords are username Lansing password keypass and username Tacoma password
keypass.
You should not run the command username Tacoma password keypass. The username Tacoma portion of the
command will create an account named Tacoma. You need an account for the other router, Lansing.
You should not run the command username Lansing keypass password. The password portion of the
command must follow the syntax password [correct_password].
You should not run the command username Tacoma keypass password. The username Tacoma portion of the
command will create an account for the wrong router, and the password portion of the command must follow
the syntax password [correct_password].
