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






2. 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?






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






4. Sh run






5. 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.






6. Router#erase startup-config






7. Set CDP timer to 90 seconds






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






9. Router#copy run tftp






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






11. 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.






12. Displays CDP timer and CDP holdtime parameters






13. To end a session from a local device






14. A network administrator wants to upgrade the IOS of a router without removing the image currently installed. What command will display the amount of memory consumed by the current IOS image and indicate whether there is enough room available to hold

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






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






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






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






20. What is the command to copy the startup-config file to DRAM?






21. 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.






22. Which command displays the configuration register setting?






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






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






25. Router#copy tftp flash






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






27. The IOS version of your directly connected neighbors






28. Which three statements accurately describe CDP?






29. Displays information about each interface using CDP - including the encapsulation on the line - the timer - and the holdtime for each interface.






30. 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?






31. 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.






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






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






34. Sh start






35. Come back to your original router console via telnet






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






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






38. You copy a configuration from a network host to a router's RAM. The configuration looks correct - yet it is not working at all. What could the problem be?






39. You have your laptop directly connected into a router's Ethernet port. Which of the following are among the requirements for the copy flash tftp command to be successful? (Choose three.)


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






41. 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?






42. Rommon 1 > confreg 0x2142






43. Turn CDP on for an interface






44. Evaluate router performance and CPU utilization






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






46. Sh host table






47. Status of each interface






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






49. Configuring a host table






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