What is the factory default value of the configuration register?
0x2102
Which option enables you to check if the Cisco IOS image on a router is corrupt or compromised?
MD5 digests
Which protocol would you use if you wanted to copy the configuration from a remote server securely?
SCP
From which two components could the router obtain Cisco IOS Software image? (Choose two.)
flash TFTP server
Where will a router search for the startup configuration if the startup configuration file does not exist in NVRAM?
TFTP server
Which configuration register boot field values cause the router to check the startup configuration file for boot system commands during the Cisco router boot process?
The correct answer is "0x2 to 0xF." If the boot field value of the configuration register is from 0x2 to 0xF, the bootstrap code parses the startup configuration file in NVRAM for the boot system commands that specify the name and location of the Cisco IOS Software image to load.
What will be the next step in the boot sequence of the router if the bootstrap code cannot locate a complete Cisco IOS image?
The correct answer is "It copies a scaled-down version of Cisco IOS Software from ROM into RAM." If a complete Cisco IOS image cannot be located, a scaled-down version of the Cisco IOS Software is copied from ROM into RAM.
Where does the decompressed Cisco IOS file reside before it is started?
The correct answer is "RAM." If the image needs to be loaded from the flash memory into RAM, it must first be decompressed. After the file is decompressed into RAM, it is started.
Which protocol is used to allow Cisco IOS image and configuration uploads and downloads over the network?
The correct answer is "TFTP." Using a network TFTP server allows image and configuration uploads and downloads over the network. (Source: Managing Cisco IOS Images)
When you copy configuration files from another source, such as TFTP, into RAM on a Cisco router, what will happen to the previous configuration?
The correct answer is "The configuration file merges with any existing configurations into RAM." When a configuration is copied into RAM from any source, the configuration merges with, or overlays, any existing configuration in RAM, rather than overwriting it.
What does the pound symbol (#) indicate when it is displayed next to a file system entry in the output of the show file systems command?
The correct answer is "a bootable disk." The bootable Cisco IOS Software is located in the flash memory, so the pound symbol (#) that is appended to the Flash listing indicates a bootable disk.
What do the exclamation points (!!!) in the output of the copy flash tftp command indicate?
The correct answer is "copying progress from flash memory to the TFTP server." The exclamation points in the output of the copy flash tftp command indicate that the copy process is taking place.
Which bits of the configuration register make up the boot field?
The correct answer is "least-significant 4 bits." The least-significant 4 bits of the configuration register are called the boot field.
What is the purpose of the setup utility?
The correct answer is "to enable you to create a basic initial configuration." The setup utility prompts the user at the console for specific configuration information to create a basic initial configuration on the router.
Which command can you use to check whether the Cisco IOS image has errors because of file transfer?
The correct answer is "verify /md5 flash:/image_name.bin." All other options are incorrect.
Which command can you use to merge the configuration in RAM with a saved configuration file on a TFTP server?
copy tftp running-config
Which Cisco IOS command can you use to examine the configuration register?
show version
Which URL prefix for Cisco network devices contains the current running configuration?
system:
