- Question
- Answer
- Side 3

- What 3 things are loaded when the router is initialized?
- 1. Bootstrap
  2. The Operating System
  3. Configuration File
- What does a router do if it cannot find a configuration file?
- Enters setup mode
- Where is the backup copy of the new configuration from setup mode stored?
- NVRAM
- What is the test called that the router performs when it powers up?
- POST
- After verifying Hardware functions what does the router do next?
- Software initialization
- Where is the bootstrap program loaded
- Rom
- What is the definition of Bootstrap
- A bootstrap is a simple preset operation to load instructions that in turn cause other instructions to be loaded into memory, or cause entry into other configuration modes
- Where are three places where the Cisco IOS can be found?
- 1. Flash
  2. TFTP Server
  3. ROM
- Where is the configuration file saved?
- NVRAM
- What 3 things does the POST Diagnostics from ROM verify.
- 1. Basic CPU operation
  2. Memory
  3. Network Interface ports
- How are configuration files loaded into main memory?
- one line at a time
- what do configuration commands do?
- 1. Start routing
  2. Supply addresses for interfaces
  3. set media charachteristics and so on
- If no valid configuration file exists in NVRAM, the OS executes a question driven configuration routine. What is this called
- System configuration Dialog or setup Dialog
- What command shows the backup config files
- Show startup-config
- What command shows the active config files
- Show running-config
- What command deletes the backup configuration file in NVRAM
- Erase startup-config
- What is the reboot command
- reload
- What is the command used to enter setup mode from the privledged exec prompt
- setup
- What is the purpose of setup mode?
- to bring up, quickly, a minimal configuration for any router that cannot find its configuration from some other source
- How do default answers appear in setup mode
- in brackets []
- what command can be pressed at any time to terminate the process and start over
- Control + C
- If you want to use the new configuration and you enter yes where will it be saved
- NVRAM
- What should you do if the MORE promp appears
- press space bar to continue
- What is the first global parameter you should enter?
- Host name
- What password is encrypted by Cisco proprietary software?
- Enable Secret
- How does the enable secret password appear on the config file?
- meaningless string of charachters
- If you answer yes to the setup configuration what will happen to the configuration file?
- it will be executed and saved to NVRAM
- if you want to change the setup configuration after you save it what must be done.
- You must configure it manually
- The script file generated by setup is additive. What does this mean?
- You can turn features on with setup but you can not turn them off.
- What 3 places can you load configuration files from?
- 1. Console
  2. NVRAM
  3. TFTP server
- What five pieces of information does the router use from the configuration files when it starts up?
- 1. Cisco IOS Software version
  2. Router Identification
  3. Boot File Locations
  4. Protocol Information
  5. Interface Configuration
- If there is no configuration file in the router, what mode do you enter to configure one?
- Setup
- What command will allow you to configure from a virtual terminal, a modem, or a console terminal?
- privledged EXEC configure
- What command configures manually from the console terminal.
- configure terminal
- What command displays the current configuration in RAM?
- Show running-config
- What command displays the saved configuration, which is the contents of NVRAM?
- show startup-config
- What command erases the contents of NVRAM?
- erase startup-config
- What does the command copy running-config tftp allow you to do?
- store a current copy of the configuration on a TFTP server.
- In copying a running-config to a host do you need to key the IP address of the host?
- Yes
- Do you need to name a config file copied to a TFTP server?
- Yes
- What mode do you need to be in, in order to manage the contents of NVRAM
- enable
- What command erases the contents of NVRAM
- erase startup-config
- Where is the runnning config stored?
- RAM
- Where is the startup or backup configuration file stored?
- NVRAM
- What command stores the current configuration into NVRAM?
- copy running-config startup-config
- What command displays the saved configuration?
- show startup-config
- If the screen prompt shows
  Router(config-if)# what are you configuring?
- the interface
- If the screen prompt shows Router(config-subif)# what are you configuring?
- the subinterface
- What mode are you in when you apply commands that affect the system as a whole?
- Global configuration
- What do you type to enter global configuration mode from the terminal
- Configure Terminal or
  Config T
- What command do you key to configure a routing protocol?
- Router "protocol" for example to configure RIP you type
  Router RIP
- What mode are all router interfaces automatically in?
- administratively down mode
- What is the clocking signal on a serial link?
- DCE
