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. Which three commands can be used to check LAN connectivity problems on a router?






2. Which command will show you the IOS version running on your router?






3. Which command will copy the IOS to a backup host on your network?






4. Rommon 1 > confreg 0x2142






5. Why is the show processes command used on a router before a debug command is entered?






6. Set CDP holdtime to 240 seconds






7. Turn off CDP completely






8. During the boot sequence - a router needs to locate and load an operating system. What is the default order the router uses to find an operating system?






9. Tells the router to look in NVRAM for the boot sequence; default configuration setting on Cisco routers; bits 13 - 8 - and 1 are on






10. Used to hold packet buffers - ARP cache - routing tables - and also the software and data structures that allow the router to function. Running-config is stored in RAM - and the IOS can also be run from RAM in some routers.






11. The IP addresses of each directly connected neighbor






12. Router(boot)(config)#config-register 0x2102






13. Router#copy flash tftp






14. You telnet into a router and you receive the following message: Password required but none set. Why was this message received?






15. Configuring a host table






16. You save the configuration on a router with the copy running-config startup-config command and reboot the router. The router - however - comes up with a blank configuration. What can the problem be?






17. Turn CDP on for an interface






18. The default configuration register setting of 0x2102 provides what function to a router?






19. Used to hold the router and switch configuration. NVRAM is not erased when the router or switch is reloaded.






20. Sh run






21. Used to control how the router boots up. This value can be seen with the show version command and typically is 0x2102 - which tells the router to load the IOS from flash memory as well as to load the configuration from NVRAM.






22. Stored in the microcode of the ROM - the ROM monitor is used for manufacturing - testing - and troubleshooting.






23. Router#copy tftp run






24. Status of each interface






25. To end a session of a device attached to your local device through Telnet






26. Stored in the microcode of the ROM - the POST is used to check the basic functionality of the router hardware and determines which interfaces are present.






27. Displays CDP timer and CDP holdtime parameters






28. Delivers information about directly connected devices






29. Ctrl+Break during router bootup; IOS is corrupt or missing; no network connectivity available to find a TFTP host; the mini-IOS from ROM doesn't load






30. Displays information about interface traffic - including the number of CDP packets sent and received and the errors with CDP






31. What is the command to copy a Cisco startup-config file to a TFTP server?






32. What keystrokes can you use to telnet into multiple devices simultaneously?






33. Router#copy run start






34. Router#erase startup-config






35. Router#copy tftp flash






36. Stored in the microcode of the ROM - the bootstrap is used to bring a router up during initialization. It will boot the router and then load the IOS.






37. See the connections made from your router to a remote device






38. Called the RXBOOT or bootloader by Cisco - the mini-IOS is a small IOS in ROM that can be used to bring up an interface and load a Cisco IOS into flash memory. The mini-IOS can also perform a few other maintenance operations.






39. You telnet to a router and make your necessary changes; now you want to end the Telnet session. What command do you type in?






40. List all active consoles and VTY ports in use






41. See the current value of the configuration register and IOS version






42. How will a 2600 series router respond if the conditions listed below exist during the boot process?






43. Which command loads a new version of the Cisco IOS into a router?






44. What information is displayed by the show hosts command? (Choose two.)






45. If NVRAM lacks boot system commands - where does the router look for the Cisco IOS by default?






46. What is an older command that you can use to copy the startup-config file to DRAM?






47. Used to start and maintain the router.






48. The corporate office sends you a new router to connect - but upon connecting the console cable - you see that there is already a configuration on the router. What should be done before a new configuration is entered in the router?






49. POST tests (in ROM) > Bootstrap loads IOS (from Flash - TFTP Server or ROM) > IOS loads startup-config from NVRAM > Startup Config loads or router is brought up in setup mode






50. Sets the IP address of the DNS server (up to 6)
