After performing a device driver upgrade on a client computer you get a system that reboots
continuously as soon as it displays the Windows XP logo. In order to correct this issue, what
should you try first?

A.
Boot into Recovery Console and use the FIXBOOT command.

B.
Reinstall device drivers in Safe Mode.

C.
Use the Last Known Good Configuration.

D.
Replace the faulty video card.

Explanation:
In versions NT and later of the Windows operating system (OS), a copy of a system’s hardware
configuration and driver settings taken from the system’s registry when the OS successfully boots.
This copy is stored in case a subsequent boot process fails, and the OS can use the record of the
Last Known Good configuration to perform a successful boot. If Windows detects a problem in the
boot process, it will add the Last Known Good configuration option to the start up menu.
