2. What are three methods of logging on to a router?
3. What is the name of the user interface mode of operation used when you cannot issue disruptive commands?
4. Can the auxiliary port be used for anything besides remote modem user access to a router? If so, what other purpose can it serve?
5. How many console ports can be installed on a Cisco 7500 router?
6. What command would you use to receive command help if you know the show command option that you cannot recall begins with a "C"?
7. While you are logged in to a router, you issue the command copy? and get a response of "Unknown command, computer name, or host." Offer an explanation as to why this error message appears.
8. Is the number of retrievable commands based on the number of characters in each command, or is it simply a number of commands, regardless of their size?
9. How can you retrieve a previously used command? (Name two ways.)
10. Instead of show ip route, which is the only command you typed since logging into the router, you now want to issue a show ip arp command. What steps would you take to do so, without simply typing show ip arp?
11. After typing show ip route 128.1.1.0, you now want to issue the command show ip route 218.1.4.0. What steps would you take to do so, without simply typing show ip route 218.1.4.0?
12. What configuration command causes the router to demand a password from the console? What configuration mode "context" must you be in; that is, what command(s) must you type before this command?
13. What configuration command is used to tell the router the password that is required at the console? What configuration mode "context" must you be in; that is, what command(s) must you type before this command?
14. What is the purpose of Flash memory in a Cisco router?
15. What is the intended purpose of NVRAM memory in a Cisco router?
16. What does the NV stand for in NVRAM?
17. What is the intended purpose of RAM in a Cisco router?
18. What is the purpose of ROM in a Cisco router?
19. What configuration command would be needed to cause a router to use an IOS image named c2500-j-l.112-14.bin on TFTP server 128.1.1.1 when the router is reloaded? If you forgot the first parameter of this command, what steps must you take to learn the correct parameters and add the command to the configuration? (Assume you are not logged in to the router when you start.)
20. What command sets the password that would be required after typing the enable command? Is that password encrypted by default?
21. What is missing from the configuration command banner "This is Ivan Denisovich's Gorno Router-Do Not Use" for it to have the correct syntax?
22. Name two commands that affect the text used as the command prompt.
23. When using setup mode, you are prompted at the end of the process as to whether you want to use the configuration parameters you just typed in. Which type of memory is this configuration stored into if you type yes?
24. What two methods could a router administrator use to cause a router to load the IOS stored in ROM?
25. What could a router administrator do to cause a router to load file xyz123.bin from TFTP server 128.1.1.1 upon the next reload? Is there more than one way to accomplish this?
26. What is the process used to update the contents of flash memory so that a new IOS in a file called c2500-j-L112-14.bin on TFFP server 128.1.1.1 is copied into flash memory?
27. Name three possible problems that could prevent the command boot net c2500-j-l. 112- 14.bin 128.1.1.1 from succeeding.
28. Two different lOS files are in a router's flash memory, one called c2500-j-l.111-3.bin and one called c2500-j-l.112-14.bin. Which one does the router use when it boots up? How could you force the other IOS file to be used? Without looking at the router configuration, what command would you use to discover which file was used for the latest boot of the router?
29. What does CDP stand for?
30. What type of interfaces is CDP enabled on by default? (Assume IOS 11.0 and beyond.)
31. What command can be used to provide as much detailed information as is possible with CDP?
32. Is the password required at the console the same one that is required when Telnet is used to access a router?
33. How could a router administrator disable CDP? What command(s) would be required on a Cisco 2501 (2 serial, 1 Ethernet) router?
34. Which IP routing protocols could be enabled using setup?
35. Name two commands used to view the configuration to be used at the next reload of the router. Which one is a more recent addition to the 105?
36. Name two commands used to view the configuration that is currently used in a router. Which one is a more recent addition to the 105?
37. The copy startup-config running-config command always changes the currently used configuration for this router to exactly match what is in the startup configuration file. (TIF). Why?
