Results from a vulnerability analysis indicate that all enabled virtual terminals on a router can be
accessed using the same password. The company’s network device security policy mandates that
at least one virtual terminal have a different password than the other virtual terminals. Which of the
following sets of commands would meet this requirement?
A.
line vty 0 6 P@s5W0Rd password line vty 7 Qwer++!Y password
B.
line console 0 password password line vty 0 4 password P@s5W0Rd
C.
line vty 0 3 password Qwer++!Y line vty 4 password P@s5W0Rd
D.
line vty 0 3 password Qwer++!Y line console 0 password P@s5W0Rd
Explanation:
ONE TO REMEMBER
The VTY lines are the Virtual Terminal lines of the router, used solely to control inbound Telnet connections. They are virtual, in the sense that they are a function of software – there is no hardware associated with them.
Two numbers follow the keyword VTY because there is more than one VTY line for router access. This eliminates B.
The default number of lines is five on many Cisco routers. This eliminates A.
Starting from 0 to 4 we have 5 terminal lines
I am to configure the Password for the VTY line, and not the console. This eliminates B and D
So thus having eliminated A, B and D, all I am left with is C
