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?
A.
The network administrator failed to save the configuration.
B.
The configuration register is set to 0x2100.
C.
The boot system flash command is missing from the configuration.
D.
The configuration register is set to 0x2102.
E.
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 runningconfig” 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 0×2142. This will make the “System Configuration Dialog” appear at the next reload.
