How would you configure the name “Didcot” on a new router?




Router>enable
Router#hostname Didcot
Router>configure
Router(config)#hostname Didcot
Router>enable
Router#config t
Router(config)#hostname Didcot
Router>enable



The router can be accessed via the console but not via Telnet.
The router can be accessed via Telnet but not via the console.
The router can be accessed both via the console and via Telnet.
The router can be accessed neither via the console nor via Telnet.
How would you configure a password to restrict console access?




Didcot#line con 0
Didcot(config)# password cisco
Didcot(config)#login
Didcot(config)#line con 0
Didcot(config)# password cisco
Didcot(config)# login
Didcot(config)# line con 0
Didcot(config-line)#password cisco
Didcot(config-line)# login
Didcot(config)# int con 0
Didcot(config-if)# password cisco
Didcot(config-if)# login
Which is true about vty lines to a router?




SW
A router always has 5 vty lines.
All vty lines must have the same password.

What is true about the command Didcot(config)#enable secret class?




It protects log-in to the router with an encrypted password.
It protects access to privileged exec mode with an encrypted password.
It protects access to user exec mode with an encrypted password.
It protects access to privileged exec mode with an unencrypted
password.
What is true about the command Didcot(config)#enable password cisco?




The password will appear in encrypted form when the configuration is
displayed.
The password will not appear when the configuration is displayed.
The password will be used in preference to an enable secret password
if one is configured.
The password will not be used if an enable secret password is
configured.
What is the purpose of the command service password-encryption?




It applies weak encryption to the enable secret password.
It applies weak encryption to passwords that are entered later and
would not be encrypted by default.
It forces the administrator to enter a password in encrypted form at logon.
It applies strong encryption to passwords that would otherwise have
weak encryption.
A student in a CCNA lab configures a router with the command enable secret
class. The student captures the running configuration as a text file and notes
that it includes the line:
enable secret 5 $1$v0/3$QyQWmJyT7zCa/yaBRasJm0
The next week, the student wants to put the same configuration back on the
router, which has had its configuration cleared. What should the student do
before using the text file to put the configuration back on a router?




SW
Nothing. The configuration file must be put back on a router exactly as
it was captured.
Add the line “service password-encryption” to the text file so that the
encrypted password is recognized.
Change the line to “enable secret class” because otherwise it will be
necessary to type in $1$v0/3$QyQWmJyT7zCa/yaBRasJm0 as the
password.
A text file cannot be used to configure a router.

An interface was configured as follows:
Didcot(config)#int fa 0/0
Didcot(config-if)#ip address 192.168.4.8 255.255.255.0
Didcot(config-if)#exit
A ping to this interface fails. What is most likely to be the problem?





The command was given at the wrong prompt and has not taken effect.
The interface is administratively shut down.
The command int fa 0/0 is ambiguous and needs to be given in full.
The subnet mask is not valid.
The description has been left out.
Which command would be the best choice to identify the problem in the
previous question?




SW
Show int fa 0/0
Show interfaces serial
Show version
Show startup-config
