Question

6. A router with a valid operating system contains a configuration file stored in NVRAM.
The configuration file has an enable secret password but no console password. When the
router boots up, which mode will display?
a. global configuration mode
b. setup mode
c. Oprivileged EXEC mode
d. user EXEC mode
7. An administrator has just changed the IP address of an interface on an IOS device. What
else must be done in order to apply those changes to the device?
a. Copy the running configuration to the startup configuration file.
b. Copy the information in the startup configuration file to the running configuration.
c. Reload the device and type yes when prompted to save the configuration.
d. Nothing must be done. Changes to the configuration on an IOS device take effect as soon as
the command is typed correctly and the Enter key has been pressed.
8. Which memory location on a Cisco router or switch will lose all content when the
device is restarted?
a. ROM
b. flash
c. NVRAM
d. RAM
9. Why would a technician enter the command copy startup-config running-config?
a. to remove all configurations from the switch
b. to save an active configuration to NVRAM
c. to copy an existing configuration into RAM
d. to make a changed configuration the new startup configuration
10. Which statement is true about the running configuration file in a Cisco IOS device?
a. It affects the operation of the device immediately when modified.
b. It is stored in NVRAM.
c. It should be deleted using the erase running-config command.
d. It is automatically saved when the router reboots.

Answer 1

6. d. user EXEC mode
- The router loads the startup configuration from NVRAM and places you in user EXEC (>) by default. You must type enable and enter the enable secret to get privileged EXEC.

7. d. Nothing must be done. Changes take effect as soon as the command is entered.
- Interface IP changes modify the running configuration immediately. To make them persistent across reloads you would save the running config to startup (copy running-config startup-config).

8. d. RAM
- RAM is volatile and loses its contents on restart. (Flash and NVRAM retain contents; ROM is non-volatile firmware.)

9. c. to copy an existing configuration into RAM
- copy startup-config running-config merges the saved startup configuration from NVRAM into the running configuration in RAM.

10. a. It affects the operation of the device immediately when modified.
- The running-config in RAM is the active configuration; changes take effect immediately but are lost on reload unless saved to startup-config.
