Subjects : cisco, it-skills, ccna
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. If NVRAM lacks boot system commands - where does the router look for the Cisco IOS by default?






2. Router#erase startup-config






3. Used on the router to hold the Cisco IOS. Flash memory is not erased when the router is reloaded. It is EEPROM (electronically erasable programmable read-only memory) created by Intel.






4. Displays CDP timer and CDP holdtime parameters






5. You need to gather the IP address of a remote switch that is located in Hawaii. What can you do to find the address?






6. 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?






7. Configuring a host table






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






9. 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.






10. Test connectivity to remote devices






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






12. Rommon 1 > confreg 0x2142






13. Router#copy tftp flash






14. Verify the amount of flash memory and the file or files being stored in flash memory






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






16. A proprietary protocol designed by Cisco to help administrators collect information about both locally attached and remote devices






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






18. A 16-bit configurable value stored in hardware or software that determines how Cisco routers function during initialization.






19. What does the command o/r 0x2142 provide?






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






21. Evaluate router performance and CPU utilization






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






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






24. 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






25. 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.






26. What should the configuration register value be after you successfully complete the password recovery procedure and return the router to normal operation?






27. Sh run






28. Set CDP holdtime to 240 seconds






29. From the 2600 series router - type reset; From the 2500 series router - type I (for initialize)






30. To end a session from a local device






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






32. Turn off domain-lookup






33. If you want to have more than one Telnet session open at the same time - what keystroke combination would you use?






34. Turn off CDP completely






35. Sh start






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






37. You are troubleshooting a connectivity problem in your corporate network and want to isolate the problem. You suspect that a router on the route to an unreachable network is at fault. What IOS user exec command should you issue?






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






39. Router#copy flash tftp






40. 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.






41. Which of the following commands enables a network administrator to verify the Application layer connectivity between source and destination?






42. Verifying your routing table






43. 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.






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






45. You are consoled into a router and you see the following output...






46. You telnet into a router and type debugging commands to help you troubleshoot a problem; however - no output appears. What command should you type to view the debug output?






47. Turn CDP off for an interface






48. Set CDP timer to 90 seconds






49. Router(config)#config-register 0x2101






50. Displays detailed information about each device connected to the device you're running the command on
