Explanation: 

ROUTER A CONFIGURATION:
!
no service password-encryption
!
enable password cisco
!
username ciscouser privilege 15 password 0 cisco
!
banner motd ^CWelcome! If you encountered any problem, please consult the administrator^C
!
line vty 0 4
password 4t&34rkf
login local
transport input telnet ssh
!
“no service password-encryption” displays the passwords in plain text, and here we see that the password is set to the easily guessable password of “cisco”.
Never say “Welcome” in your banner message, it is basically an open invitation to access the device without permission.
