Objective 4.3 Restore and Back Up the Operating System, System State Data, and User Data
24-23
Objective 4.3 Answers
1. Correct Answers: C
A. Incorrect: The Boot.ini file specifies the set of choices that are presented to the
user before the operating system is loaded. The Boot.ini file can be configured to
allow for booting between several different instances of Windows, but it cannot be
used to modify the configuration of Windows XP.
B. Incorrect: The System Restore tool is used to roll back the configuration of a
Windows XP system. However, it can be used only after the operating system has
booted. In this case, the System Restore tool is inaccessible because the operating
system is unbootable.
C. Correct: The Last Known Good Configuration is a copy of the system state stored
in the HKEY_LOCAL_MACHINE\System\CurrentControlSet registry key when a
user last successfully logged on. You can revert to this backup configuration by
rebooting the computer and pressing F8 when prompted to select the operating
system from which to start. From the Windows XP Professional Advanced Options
menu, select the Last Known Good Configuration option.
D. Incorrect: The Recovery Console can be a useful tool for recovering a system
that does not boot correctly, but it is not useful for restoring the last working configuration
of a system. Use the Recovery Console only when all other methods
have failed.
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 problems
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 Configuration
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 interface
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.
