ANS. ISR IS IDEAL FOR SMALL TO MEDIUM SIZED BUSINESSES AND FOR ISP MANAGED CUSTOMERS.

4. WHAT DOES THE (IOS) SOFTWARE FEATUES ENABLE A CISCO DEVICE TO DO?ANS. IOS SOFTWARE PROVIDES FEATUES THAT ENABLE A CISCO DEVICE TO SEND AND RECEIVE NETWORK TRAFFIC USINGA WIRED OR WIRELESS NETWORK. CISCO IOS SOFTWARE IS OFFERED TO CUSTOMERS IN MODULES CALLED IMAGES.. THESE IMAGES SUPPORT VARIOUS FEATURES FOR BUSINESSES OF EVERY SIZE..

5. WHAT IS AN IP BASED IMAGE?ANS. THE ENTRY LEVEL CISCO IOS SOFTWARE IMAGE IS CALLED THE IP BASED IMAGE. THE IP BASED IMAGE SOFTWARE SUPPORTS SMALL TO MEDIUM SIZED BUSINESSES AND SUPPORTS ROUTING BETWEEN NETWORKS.

8. WHAT IS SHIPPED WITH EACH CISCO DEVICE?ANS. EACH DEVICE IS SHIPPED WITH CABLES AND DOCUMENTATION NEEDED TO POWER UP THE DEVICE AND BEGIN THE INSTALLATION.

9. WHAT ARE THREE TOOLS REQUIRED TO INSTALL A NEW CISCO DEVICE?ANS. THREE TOOLS REQUIRED:

1. CABLE TIES PC WITH TERMINAL EMULATION PROGRAM2. NUMBER 2 PHILIP SCREWDRIVER3. CABLES FOR WAN INTERFACES, LAN INTERFACES AND USB INTERFACES.

10. WHAT SHOULD YOU READ BEFORE BEGINNING ANY EQUIPMENT INSTALLATION?ANS. BEFORE ATTEMPTING ANY INSTALLATION BE SURE TO READ THE QUICK START GUIDE

11. WHAT ARE THE SIX STEPS TO PERFORM A POWER UP PROCEDURE ON AN ISR 1841?ANS. THE STEPS:

1. Securely mount and ground the device

2. Seat the external compact flash card3. Connect the power cable4. Configure the terminal emulation software on the pc and connect the pc to

the console port.5. Turn on the router6. Observe the startup messages on the pc as the router boots up.

12. LIST THE 3 STAGES OF THE ROUTER BOOTUP PROCESS.ANS. THE THREE STAGES OF THE BOOTUP:

1. PERFORM POWER-ON SELF TEST (POST) AND LOAD THE BOOTSTRAP PROGRAM. POST IS USED TO TEST ROUTER HARDWARE

2. LOCATE AND LOAD THE CISCO IOS SOFTWARE3. LOCATE AND EXECUTE THE STARTUP CONFIGURATION FILE OR ENTER SETUP

MODE. TO BEGIN THE CONFIGRUATION PROCESS.13. WHAT ARE 3 PLACES WHERE IOS CISCO FILES CAN BE LOCATED?

ANS. THREE PLACES THE FILES CAN BE LOCATED:1. FLASH MEMORY2. TFTP SERVER3. ANOTHER LOCATION INDICATED IN STARTUP CONFIGURATION FILE.

14. WHAT HAPPENS IF A CONFIG FILE IS NOT FOUND?ANS. THE ROUTER PROMPTS USER TO ENTER SETUP MODE.,TO BEGIN THE CONFIGURATION PROCESS.

15. WHAT HAPPENS IF THE CONFIG FILE IS FOUND?ANS. IT IS COPIED INTO RAM AND PROMPT CONTAINING THE HOST NAME IS DISPLAYED.

16. WHAT IS THE STARTUP CONFIGURATION?ANS. THE STARTUP CONFIGURATION FILE IS THE SAVED CONFIGURATION FILE THAT SETS THE PROPERTIES OF THE DEVICE EACH TIME THE DEVICE IS POWERED UP. THIS FILE IS STORED IN NON VOLATILE RAM.

17. WHERE IS THE STARTUP CONFIGURATION FILE STORED?ANS THE STARTUP CONFIGURATION FILE IS STORED IN NON VOLATILE RAM.

18. WHAT HAPPENS TO THE FILES IN NVRAM WHEN POWER TO THE DEVICE IS POWERED OFF?ANS. WHEN THE DEVICE IS POWERED OFF THE CONFIG FILES ARE LOST.

19. WHAT DOES A CISCO ROUTER DO WHEN IT IS POWERED ON?ANS. WHEN THE ROUTER IS FIRST POWERED ON IT LOADS THE CISCO IOS SOFTWARE TO WORKING MEMORY, OR RAM.

20. WHAT IS THE SECOND THING A CISCO ROUTER WILL DO WHEN POWERED UP?ANS. THE STARTUP CONFIGURATION FILE IS COPIED FROM NVRAM TO RAM.

21. WHAT DOES THE TERM RUNNING CONFIGURATION REFER TO?ANS. RUNNING CONFIG REFERS TO THE CURRENT CONFIGURATION RUNNING IN RAM ON THE DEVICE. THIS FILE CONAINS THE COMMANDS USED TO DETERMINE HOW THE DEVICE OPERATES ON THE NETWORK. THE RUNNING CONFIGURATION FILES IS STORED IN THE WORKING MEMORY OF THE DEVICE.

22. WHAT HAPPENS TO THE INFORMATION ON RAM OR RUNNING CONFIGURATION WHEN IT IS TURNED OFF?ANS. THE RUNNING CONFIGURATION IS LOST EACH TIME THE DEVICE IS SHUT DOWN.

23. IF CHANGES ARE MADE TO THE RUNNING CONFIGURATION WHAT IS NECESSARY IN ORDER FOR THE CHANGES TO BE SAVED WHEN THE DEVICE IS POWERED OFF?ANS. IT IS NECESSARY TO MANUALLY COPY THE RUNNING CONFIGURATION TO THE STARTUP CONFIGURATION FILE. COPY RUNNING CONFIGURATION STARTUP CONFIG OR COPY RUN START SAVES THE RUNNING CONFIG TO THE STARTUP CONFIG FILE.

24. WHAT COMMAND IS USED TO SAVE THE ROUTER’S RUNNING CONFIGURATION TO THE STARTUP CONFIGURATION ?ANS. COPY RUNNING-CONFIG STARTUP-CONFIG

25. WHAT COMMAND CAN BE USED TO TROUBLESHOOT SOME OF THE BASIC HARDWARE AND SOFTWARE COMPONENTS USED DURING THE BOOTUP PROCESS?ANS. SHOW VERSIONCOMMAND.

26. WHAT DOES THE CONFIGURATION REGISTER SETTING OF 0X2102 TELL THE ROUTER TO DO?ANS.0X2102 IS THE FACTORY DEFAULT SETTING FOR THE CONFIGURATION REGISTER. THIS VALUE INDICATES T HAT THE ROUTER ATTEMPTS TO LOAD A CISCO SOFTWARE IMAGE FROM FLASH AND LOADS THE STARTUP CONFIGURATION FILE INTO VNVRAM.

27. IF THERE IS A SECOND VALUE IN PARENTHESIS WHAT DOES IT DENOTE?ANS. A SECOND VALUE DENOTES THE CONFIGURATION REGISTER VALUE TO B E USED DURING THE NEXT RELOAD OF THE ROUTER.

28. LIST THREE REASONS THAT A ROUTER MAY FAIL TO BOOTUP PROPERLY.ANS. REASONS THE ROUTER MIGHT BOOTUP IMPROPERLY:

1. CORRUPT OF MISSING IOS FILE2. INCORRECT LOCATION FOR CISCO IMAGE3. INADEQUATE MEMORY TO LOAD CISCO IMAGE.

29. IF THE ROUTER FAILS TO BOOT THE IOS HOW DOES IT BOOT UP?ANS. IF THE ROUTER FAILS TO BOOT THE IOS IT THEN BOOTS UP IN ROM MONITOR. ROMmon SOFTWARE IS A SIMPLE COMMAND SET STORED IN READ ONLY MEMORY.

30. WHEN THE ROUTER BOOTS UP TO ROMmon MODE WHAT IS ONE OF THE FIRST STEPS IN TROUBLESHOOTING?ANS. ONE OF THE FIRST STEPS IN TROUBLESHOOTING IS TO LOOK IN FLASH MEMORY FOR A VALID IMAGE USING THE DIR FLASH: COMMAND IF AN IMAGE IS LOCATED ATTEMPT TO BOOT THE IMAGE WITH THE BOOT FLASH:COMMAND.

31. IF THE ROUTER BOOTS PROPERLY WITH THE BOOT FLASH: COMMAND, WHAT ARE TWO POSSIBLE R EASONS WHY THE CISCO IOS IMAGE DID NOT LOAD FROM FLASH INITIALLY?ANS. FIRST USE THE SHOW VERSION VERSION COMMAND TO CHECK THE CONFIGURATION REGISTER TO ENSURE T HAT IT IS CONFIGURED FOR THE DEFAULT BOOT SEQUENCE. IF THE CONFIGURATION REGISTER VALUE IS CORRECT USE THE SHOW STARTUP-CONFIG COMMAND TO SEE IF THERE IS A BOOTSYSTEM COMMAND THAT INSTRUCTS THE ROUTER TO USE A DIFFERENT LOCATION FOR THE CISCO IOS IMAGE.

32. WHAT DOES AN OUT-OF-BAND MANAGEMENT CONNECTION REQUIRE?

ANS. OUT-OF-BAND MANAGEMENT REQUIRES A COMPUTER TO BE DIRECTLY CONNECTED TO THE CONSOLE PORT OR AUXILLARY PORT (AUX) OF THE NETWORK DEVICE BEING CONFIGURED. THIS TYPE OF CONNECTION DOES NOT REQURE THE LOCAL NETWORK CONNECTIONS ON THE DEVICE TO BE ACTIVE

33. WHY DO TECHNICIANS USE OUT-OF-BAND MANAGEMENT TO INITIALLY CONFIGURE A NETWORK DEVICE?ANS. THEY USE OUT-OF-BAND MANAGEMENT TO INITIALLY CONFIGURE A NETWORK DEVICE BECAUSE UNTIL PROPERLY CONFIGURED THE DEVICE CANNOT PARTICIPATE IN THE NETWORK. OUT-OF-BAND MANAGEMENT IS ALSO USEFUL WHEN THE NETWORK CONNECTIVITY IS NOT FUNCTIONING CORRECTLY AND THE DEVICE CANNOT BE REACHED OVER THE NETWORK. PERFORMING OUT-OF-BAND TASKS REQUIRES A TERMINAL EMULATION CLIENT INSTALLED ON THE PC.

34. WHEN IS OUT-OF-BAND MANAGEMENT USEFUL?ANS. OUT-OF-BAND MANAGEMENT IS USEFUL WHEN THE NETWORK CONNECTIVITY IS NOT FUNCTIONING CORRECTLY AND THE DEVICE CANNOT BE REACHED OVER THE NETWORK.

35. WHEN IS IN-BAND MANAGEMENT USED?ANS. IN-BAND MANAGEMENT IS USED TO MONITOR AND MAKE CONFIGURATION CHANGES TO A NETWORK DEVICE OVER A NETWORK CONNECTION.

36. WHAT MUST BE CONNECTED FOR A COMPUTER TO CONNECT TO THE DEVICE AND PERFORM IN-BAND MANAGEMENT?ANS. AT LEAST ONE NETWORK DEVICE INTERFACE ON THE DEVICE MUST BE CONNECTED TO THE NETWORK AND BE OPERATIONAL. EITHER TELNET HTTP SSH CAN BE USED TO ACCESS A CISCO DEVICE FOR IN-BAND MANAGEMENT.
