To upload a new version of the IOSE. To allow a new memory upgrade to be recognized by the routerAnswer: BExplanation:About 99 percent of the time someone uses a config-register, it's more than likelybecause of a lost router password. The two config-registers for recovering passwords are0x2102 and 0x2142.The first config-register, 0x2102, is the normal config-register if you boot the router frominternal Flash. You can see this config-register by using the show version command.In this output, you'll notice the last line says, "Configuration register is 0x2102." This isnormal.But let's say you forgot the router's password.
To recover this password (as long as it'sunencrypted), boot the router and bypass the startup-config using config-register 0x2142;you should then be able to see the password in the startup-config. You can use the samemethod for encrypted passwords, but you'll need to overwrite the original password witha new one. To change the configuration register, enter the following:Router(config)# config-register 0x2142This will instruct the router to bypass the configuration and boot up as if it were a brandnew router using factory default settings.QUESTION 363:After making some network changes you power off and then power on your CiscoActualtests.com - The Power of Knowing640-802router named CK1 .
What sequence of events occurs when CK1 is powered up?A. Perform POST, locate configuration statements, apply configuration statements, locateCisco IOS software, and load Cisco IOS software.B. Locate Cisco IOS software, load Cisco IOS software, locate configuration statements,apply configuration statements, and perform POST.C. Test software routines, POST, load configuration files, load Cisco IOS software, testCisco IOS software.D.
Perform POST, locate Cisco IOS software, load the Cisco IOS software, locateconfiguration statements, and apply configuration statements.E. Load and test IOS, load configuration files, test software routines, POST.F. None of the aboveAnswer: DExplanation:Upon initial start up, Cisco routers perform the following steps in order:1. The router performs a power-on self-test (POST) to discover and verify the hardware.2. The router loads and runs bootstrap code from ROM.3. The router finds the IOS or other software and loads it.4. The router finds the configuration file and loads it into running config.QUESTION 364:You are the network administrator at Certkiller . You need to perform passwordrecovery on Router CK1 .
What must you modify in the password recovery process?(Choose two.)A. Configuration registerB. NVRAMC. Boot flashD. CMOSE. FlashAnswer: A, BExplanation:Recovering a Lost PasswordThis section describes how to recover a lost enablepassword and how to enter a new enable secret password.Password recovery consists of the following major processes:Determining the Configuration Register Value1. With this process, you determine the configuration of the router, so that you mayrestore the configuration after the password is recovered.Resetting the RouterActualtests.com - The Power of Knowing640-8021. With this process, you reconfigure the router to its initial startup configuration.
Youthen display the enable password, if one is used.Resetting the Password1. If you are using an enable secret password, you enter a new password with thisprocess. You then restore the router to its prior configuration.Resetting the Configuration Register Value1. If you are using an enable password, you use this process to restore the router to itsprior configuration.QUESTION 365:How can a Certkiller administrator determine if a router has been configured whenit is first powered up?A. A configured router prompts for a passwordB. A configured router goes to the privileged mode promptC.
An un configured router goes into the setup dialogD. An un configured router goes to the enable mode promptAnswer: CExplanation:If a non-configured router is started, then it goes into setup mode and ask for theminimum configuration parameters (hostname, IP address to interfaces, enable password,etc). If the router is already configured it boots by implementing the saved startup-config.QUESTION 366:What will cause a Certkiller router to enter setup mode? (Choose two)A.
The configuration file is missing in NVRAM.B. The configuration register is set to 0x2100.C. Boot system commands are misconfigured in the running-configuration.D. The setup command was issued from the privileged mode prompt.E. The IOS is missing.F. The IOS is corrupt.Answer: A, DExplanation:When router boots up, it checks the valid configuration into NVRAM and tries to loadthe configuration. If there is not configuration router automatically goes into setupdialog. From setup dialog, you able to configuration the basic configuration. As well youcan run the setup command manually from privileged mode using the setup command.Actualtests.com - The Power of Knowing640-802QUESTION 367:Refer to the graphic.
A network associate is planning to copy a new IOS image intothe Certkiller 1 router. This new image requires 8 MB of flash memory and 32 MB ofRAM. How will the IOS proceed with the copy process?A. The new IOS will be copied into flash memory and the current image will remain.B. IOS will issue an error message because flash memory is not large enough to hold thenew image.C.
During the copy process, the current IOS image will be erased.D. The current IOS image must be manually erased before IOS will allow the new imageto be copied.Answer: AExplanation:According to the output shown above, the existing IOS is 8760520 bytes (8M) and thetotal size of the flash on this device is 24567K (24M). The new IOS only requires anadditional 8 MB, so it will be copied on to the flash directly and both images will resideon the flash. The existing IOS is only overwritten it there is insufficient space to holdboth.QUESTION 368:What is the default configuration register setting on most Cisco routers?A.
0x2104B. 0x2012C. 0x2210D. 0x2102E. 0x2142F. None of the aboveAnswer: DActualtests.com - The Power of Knowing640-802Explanation:About 99 percent of the time someone uses a config-register, it's more than likelybecause of a lost router password. Normally, the two config-registers for recoveringpasswords are 0x2102 and 0x2142.The first config-register, 0x2102, is the normal config-register if you boot the router frominternal Flash.
You can see this config-register by using the show version command.In this output, you'll notice the last line says, "Configuration register is 0x2102." This isnormal.QUESTION 369:During the boot sequence, a Certkiller 2800 series router needs to locate and load anoperating system.
What is the default order the router uses to find an operatingsystem?A. ROM, TFTP server, FlashB. Flash, TFTP server, ROMC. Flash, NVRAM, TFTP serverD. Flash, ROM, TFTP serverE. Flash, TFTP server, RAMAnswer: BExplanation:Booting up the Router:Cisco routers can boot Cisco IOS software from these locations:1. Flash memory2. TFTP server3.
ROM (not full Cisco IOS)Multiple source options provide flexibility and fallback alternatives.Reference: http://www.svrops.com/svrops/documents/ciscoboot.htmQUESTION 370:What will a new Certkiller router do during startup if a configuration file is notlocated in NVRAM?A. It will search for the configuration file in the locations specified by boot systemcommands.B. It will search for the configuration file in flash and if no configuration file is foundthere, it will enter the setup dialog.C. It will search for the configuration file on a TFTP server and if no configuration file isfound there, it will enter the setup dialog.Actualtests.com - The Power of Knowing640-802D.
It will search for the configuration file in flash and if no configuration file is foundthere, it will load a limited configuration file from ROM.E. It will search for the configuration file on a TFTP server and if no configuration file isfound there, it will load a limited configuration file from ROM.Answer: CExplanation:When a router boots and is able to locate the IOS it begins to load the configuration file.The configuration file, saved in NVRAM, is loaded into main memory and executed oneline at a time.
These configuration commands start routing processes, supply addressesfor interfaces, and set media characteristics.If no configuration file exists in NVRAM, the router attempts a network boot and sends abroadcast request for the file on a TFTP server. If this is also not found, the operatingsystem executes a question-driven initial configuration routine called the systemconfiguration dialog.QUESTION 371:A Certkiller router boots to the prompt shown in the exhibit below.
What does thissignify, and how should the network administrator respond?Exhibit:A. This prompt signifies that the configuration file was not found in flash memory. Thenetwork administrator should use TFTP to transfer a configuration file to the router.B.
This prompt signifies that the IOS image in flash memory is invalid or corrupt. Thenetwork administrator should use TFTP to transfer an IOS image to the router.C. This prompt signifies that the configuration file was not found in NVRAM. Thenetwork administrator should follow the prompts to enter a basic configuration.D. This prompt signifies that the router could not authenticate the user. The networkadministrator should modify the IOS image and reboot the router.Answer: BExplanation:The default boot sequence for Cisco IOS software:1. NVRAM2. Flash (sequential)3. TFTP server (network boot)Actualtests.com - The Power of Knowing640-8024.
ROM (partial IOS)If a router boots up in ROM mode as shown in this example, it means that the router wasunsuccessfully able to find a valid IOS to boot from, and a valid IOS image will need tobe loaded onto it.QUESTION 372:A Certkiller router boots up in ROMMON mode.
What is ROM Monitor(ROMMON)?A. A memory component for storing the saved configuration fileB. A memory management toolC. An operating system used for hardware troubleshooting and for password recoveryD. Temporary storage space for the router operating filesE. The source of the primary Cisco IOS software imageF.
None of the aboveAnswer: CExplanation:The ROM Monitor is a very limited code set that enables you to perform elementaryfunctions to manually get the router or switch back to a functioning state. You canperform low-level diagnostics and even copy a new IOS file to the Cisco device over theconsole port.
