Question:
Refer to the exhibit. A network administrator configures a new router and enters the copy startup- config running-config command on the router. The network administrator powers down the router and sets it up at a remote location. When the router starts, it enters the system configuration dialog as shown. What is the cause of the problem?

• The network administrator failed to save the configuration.
• The configuration register is set to 0x2100.
• The boot system flash command is missing from the configuration.
• The configuration register is set to 0x2102.
• The router is configured with the boot system startup command.

Explanation: The “System Configuration Dialog” appears only when no startup configuration file is found. The network administrator has made a mistake because the command “copy startup-config running- config” will copy the startup config (Which is empty) over the running config (Which is configured by the administrator). So everything configured was deleted. Note: We can tell the router to ignore the start-up configuration on the next reload by setting the register to 0?142. This will make the “System Configuration Dialog” appear at the next reload.
