Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can
study here
.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Privileged mode
Router(config)#interface Tunnel
Which of the following commands sets the secret password to Cisco?
Router#
Configure the interface IP address to '10.1.5.255 255.255.252.0'
2. Config t - line vty 0 4 - no login
Set telnet connection to have no password
delete the configuration stored in NVRAM
What keystroke will terminate setup mode?

3. Encrypts passwords; sh run - config t - Router(config)#no service password-encryption

4. If no commands have been typed in 1 minute and 44 seconds - the console connection will be closed
Router(config-router)#
Exec-timeout 1 44
Router#access-enable
Tab

% Incomplete command
Which of the following commands will display the current IP addressing and the layer 1 and 2 status of an interface? (Choose three.)

Router#access-enable
Router(config)#interface Lex
Router(config)#interface FastEthernet
% Ambiguous command:
11. Displays information about the physical interface itself. It'll also give you the type of serial cable plugged into a serial port. Usually - this will only be a DTE cable that plugs into a type of data service unit (DSU)

14. Copy start run doesn't replace the configuration - it appends it. To completely replace the running-config with the startup-config - you must reload the router.
You want to totally reinitialize the router and replace the current running-config with the current startup-config. What command will you use?

Router(config-subif)#
19. Show controllers int
see if a serial interface needed to provide clocking
set a user-mode password for the console port
Router(config-router)#
% Invalid input detected at '^' marker.
