THE SYSTEM RESTORE UTILITY IS USEFUL FOR TROUBLESHOOTING PROBLEMSCAUSED BY SYSTEM MISCONFIGURATIONS
2.
Correct Answers: C, D, and E
A. Incorrect:
The System Restore utility is useful for troubleshooting problems
caused by system misconfigurations. However, it can be used only if the system is
bootable.
B. Incorrect:
The Last Known Good Configuration is a quick way to resolve prob-
lems caused by misconfigurations and faulty drivers. Although the Last Known
Good Configuration is available at the boot menu and can therefore be used in
this scenario, it would not resolve the problem because the problem is not related
to a misconfiguration. Failure to boot after a power failure is generally caused by
corrupted files or a damaged hard disk—neither of which Last Known Good Con-
figuration is capable of repairing.
C. Correct:
Safe mode might or might not work in this scenario, but it is the first
thing to try. Safe mode loads a minimal set of drivers, and as such, it has a higher
chance of successfully booting than Windows XP Professional’s standard boot
mode. If safe mode does start successfully, you can use the graphical user inter-
face to diagnose the hardware problems. If you determine that system files have
been damaged, you can initiate a scan of the disk and, if necessary, restore files
from the system CD.
D. Correct:
The Recovery Console is a useful tool for recovering a system that does
not boot correctly. If the system has the recovery console installed, it is an option
on the boot menu. If it is not installed, insert the Windows XP Professional CD and
boot from the CD—the Recovery Console is an option. Recovery Console is com-
mand-line only, so it is not as convenient for diagnosis and troubleshooting as safe
mode. However, because it can be loaded from a CD, it starts even if the system’s
hard disk is completely destroyed. In this scenario, use the Recovery Console to
diagnose the extent of the damage. If you determine that system files have been
damaged, you can initiate a scan of the disk and, if necessary, restore files from
the system CD.
E. Correct:
You use ASR only after attempts to resolve the problem with safe mode
and the Recovery Console have failed. If the hard disk is functional, but files have
been damaged, ASR can make the Windows XP Professional installation bootable.
If the hard disk itself is damaged, you need to fix those errors or replace the hard
disk before using ASR.
F. Incorrect:
The Device Manager is a useful tool for diagnosing problems relating
to hardware drivers. However, it is accessible only after the system has success-
fully booted. In this scenario, you cannot get access to the Device Manager tool
unless you first start safe mode.
