Question | Answer |
---|---|
Boot Flash contains... | RX Boot |
NVRAM contains... | Startup Config/Config Reg |
DRAM contains... | Uncompressed IOS, Running config, buffers, and routing tables. |
ROM (Boot ROM) contains the _____ program. | ROM Monitor |
FLASH contains... | IOS Compressed |
___ does this. Uses the EEPROM for startup diagram/Rommon and loads IOS. On boot, if no IOS file is present, it will boot into an emergency mode called Rommon. | Boot ROM |
When the router boots, if no IOS file is present, it will boot into an emergency mode called Rommon, which allows some limited commands to be entered to recover the router and load another IOS. This is know as _____ _____ mode. | boot strap |
_______ stores router startup configuration and configuration register. | NVRAM |
The startup config is not erased when the router reloads. Location? | NVRAM |
________ contains IOS and some configuration files. | Flash/PCMCIA |
Also known as RAM, it stores full IOS, running configuration, and routing tables. | DRAM |
_______ system diagnostics and startup. | ROM Monitor |
The _______ has a very small code in it to check for attached memory and interfaces. | ROM Monitor |
______ is a mini-IOS, and allows for an upload of full IOS. | RxBoot |
It is also know as the boot loader and can be used to perform some router maintenance activities. | RxBoot |
Not strictly a router component, it is stored in NVRAM and pulled into DRAM on boot up. | router config |
Sets instructions for booting and can perform a password recovery. | the Configuration Register |

If the IOS to boot from is too large to fit into flash memory, what can be used to boot from? | TFTP server |
Which files would you usually find in DRAM? | Also known as RAM, it stores full IOS, running configuration, and routing tables. |
Where is the compressed IOS held? | In Flash memory |
You want to boot the router and skip the startup configuration. What configuration register setting do you require? | 0x2142 |
Which command put the running configuration into NVRAM? | Router# copy run start |
Which command will copy your startup configuration into a network server? | Router# copy startup-config tftp |
You want to boot your router from a network server holding the IOS. Which command will achieve this? | Router(config)# boot system tftp |
