Objective 4.3 Restore and Back Up the Operating System, System State Data, and User Data<br />

24-27<br />

B. Correct: By restoring the computer to an earlier restore point, you might be able<br />

to remove the settings that are causing problems on the computer. Hopefully,<br />

Windows XP automatically created a restore point when James ran the update.<br />

C. Incorrect: Use the Last Known Good Configuration only if the system becomes<br />

unbootable. In this case, it could not possibly help because James has already<br />

logged into the computer. The Last Known Good Configuration settings are overwritten<br />

each time a user successfully logs in.<br />

D. Incorrect: Safe mode is a valuable tool for repairing a system that is having problems<br />

booting. However, use it only after the system has failed and you can no<br />

longer boot normally.<br />

E. Incorrect: The Recovery Console can salvage systems that are otherwise completely<br />

unbootable. Because James’ computer does boot successfully, using<br />

Recovery Console is unnecessary. You can perform your troubleshooting from a<br />

standard Windows session.<br />

8. Correct Answers: B<br />

A. Incorrect: Although it is possible for backup files to become corrupted, there is<br />

an incompatibility between the Windows 98 backup tool and the Windows XP<br />

backup tool that is causing this problem.<br />

B. Correct: As described by Microsoft Knowledge Base article 305381, the Backup<br />

tool included with Windows XP cannot open compressed backups created in Windows<br />

95, Windows 98, and Windows Me. The only way to access the backup file<br />

is to restore it by using one of those compatible operating systems.<br />

C. Incorrect: In this scenario, the problem is not likely to be caused by insufficient<br />

file permissions.<br />

D. Incorrect: Windows 98 did not provide encryption for backup files and did not<br />

have a dedicated administrator user account.
