 40.  A.  The command 

exec-timeout 0 0 will disable auto-disconnect for idle privileged exec 

sessions. The command 

exec-timeout 0 is incorrect. The command timeout 0 0 is 

incorrect. The command 

no exec-timeout is incorrect as it will remove any configured 

exec-timeout from the configuration.

 41.  B.  The line on which you are connected is always preceded by an asterisk. In this 

example, you are connected to the router via line VTY 0. All other lines are remotely 

connected for other administrative sessions on the switch.

 42.  D.  After configuring the username and password combinations that will be used on the 

switch or router, you will need to configure the line(s) that will use local authentication. 

The command used inside of the line is 

login local. This will apply to all the transport 

methods configured on the line. The command 

new aaa model is incorrect. The 

command 

local authentication is incorrect regardless of where it is configured.

 43.  D.  The command 

enable algorithm-type scrypt secret Password20! will change 

the enable password to Password20! and use the scrypt algorithm type. The command 

enable secret 9 is incorrect. The command service password-encryption scrypt is 

incorrect. The command 

enable secret algorithm-type scrypt is incorrect.

 44.  D.  The default encryption method for passwords configured for lines is clear text. If 

you want to encrypt the password, you should use the 

service password-encryption 

command. When the command 

service password-encryption is used, the password 

will be encrypted with an MD5 hash, otherwise known as a Cisco level 7 encryption. All 

of the other options are incorrect.

 45.  B.  The command 

exec-timeout 30 0 will change the idle time to 30 minutes and zero 

seconds. If a privileged exec session is idle for 30 minutes, the network admin will be 

disconnected. The command 

exec-timeout 30 0 is incorrect when configured from a 

global configuration prompt. The command 

exec-timeout 0 30 is incorrect because it 

will time out a user after zero minutes and 30 seconds. The command 

timeout 30 0 is 

incorrect.

 46.  D.  The command 

clear line vty 2 will disconnect a remote admin connected to the 

switch. Nothing stops the admin from reconnecting to the switch again. The command 

no enable secret is incorrect because it will only prevent future enable sessions. The 

command 

no line vty 2 is incorrect; you cannot negate a physical line. The command 

disconnect line vty 2 is incorrect.

 47.  C.  The exec banner will display a message to authenticated users who have successfully 

logged in, regardless of whether they are connected via Telnet or SSH. The message of 

the day (MOTD) banner is displayed when a user attempts to login. The login banner is 

displayed after the MOTD but before initial login. An incoming banner is used for reverse 

Telnet connections and does not normally apply.
