1 Which command will copy an IOS image from a TFTP server to a router?

• Router# copy tftp flash*
• Router# copy flash tftp
• Router(config)# copy tftp flash
• Router(config)# copy flash tftp

2 Routers have different types of memory. Choose the answer that describes flash memory.

• provides working storage
• stores a fully functional IOS image*
• stores the startup configuration file
• initializes the code used to boot the router

3 The router has been configured with a valid configuration file. Which of the following could be a cause for a router not booting normally? (Choose two.)

• The flash image is corrupt.*
• A console cable is disconnected.
• The flash image is located in NVRAM.
• The startup configuration file is incomplete.*
• The router encountered a hardware error.

4 Which command will backup configuration files from RAM to NVRAM or a TFTP server?

• backup
• copy
• telnet*
• move

5 Which command is used to change the order in which the router looks for system bootstrap information?

• config-image
• config-system
• config-register*
• config-bootfield
• config system bootstrap

6 What does a configuration register setting of 0x2102 indicate on a router?

• It tells the router to locate and load the IOS from NVRAM.
• It tells the router to locate and load the IOS from FLASH.
• It tells the router to bypass the configuration in NVRAM.
• It tells the router to look in the startup configuration for boot system commands.*

7 Which command will display the source of the system boot image?

• Router# show version
• Router# show config-register
• Router# show start-up config
• Router# show running-config
• Router# show flash

8 Which part of the configuration register indicates the location of the IOS?

• the bootstrap
• the boot field*
• the IOS locator
• the system image loader

9 Which of the following are steps in saving a router configuration file to a TFTP server? (Choose three.)

• Enter configuration mode.
• Enter the IP address to the TFTP server.*
• Use the copy running-config tftp command.*
• Use the copy tftp running-config command.
• Name the configuration file or accept the default name.*

10 The Cisco IOS image naming convention allows identification of different versions and capabilities of the IOS. What information can be gained from the filename c2600-d-mz.121-4? (Choose two.)

• The "mz" in the filename represents the special capabilities and features of the IOS.
• The file is uncompressed and requires 2.6 MB of RAM to run.
• The software is version 12.1, 4th revision.*
• The file is downloadable and 121.4MB in size.
• The IOS is for the Cisco 2600 series hardware platform.*

11 What command can be used in ROM monitor mode to run the IOS image in flash?

• rommon1> config-register 0x2102
• rommon1> boot flash:filename*
• rommon1> xmodem:filename
• rommon1> boot system flash:filename
• rommon1> reload system flash:

12 Which two items below are required by routers in order for them to perform their basic operations? (Choose two.)

• a tftp server*
• a configuration file
• a configuration register file*
• an operating system file
• a DNS table

13 Where does a router look for boot system statements?

• ROM
• RAM
• NVRAM*
• Flash

14 Routers have different types of memory. Choose the answer that describes NVRAM.

• provides working storage
• stores a fully functional IOS image
• stores the startup configuration file*
• initializes the code that is used to boot the router
  

15 If a router cannot find a valid configuration file during the startup sequence, what will occur?

• The startup sequence will reset.
• The router will prompt the user for a response to enter setup mode.*
• The startup sequence will halt until a valid configuration file is acquired.
• The router will generate a default configuration file based on the last valid configuration.
• The router will monitor local traffic to determine routing protocol configuration requirements.

16 If the configuration register instructs a router to look for configuration information in NVRAM and no boot system commands exist there, from where will the router next attempt to boot the IOS?

• RAMR
• ROM
• FLASH*
• EPROM
• ROMMON

17 Which of the following can be configured as a source for the IOS image by using the boot system command? (Choose two.)

• TFTP server*
• HTTP server
• Telnet server
• Flash memory*
• NVRAM memory

18 If boot system commands have been configured, which of the following could happen if a router fails to obtain an IOS image from the primary sources during bootup?
The router will l

• oad a subset of a full IOS version from system ROM.
• The router will attempt to reboot two times before failing.
• The router will load the last good IOS image from NVRAM.*
• The administrator will be prompted to load a valid IOS image.
  

19 An IOS image can be copied into flash from a TFTP server. Which of the following statements are true regarding this process? (Choose three.)

• A series of "!'s" are displayed as the image is downloaded successfully to flash.*
• The copy tftp flash:filename ip address command is used to copy the IOS from the server to flash.
• After the new flash image is downloaded, it is verified.*
• A series of "e's" are displayed as the current IOS image is erased from flash.*
• Flash must be cleared with the erase command prior to beginning the download process.
