Chapter 19: Troubleshooting Theory, OSs, and Security

1. D. Windows Update automatically (by default) finds, downloads, and installs service packs and other Windows updates. None of the other options are real utilities.

2. B. Safe Mode only loads basic drivers, such as a standard VGA video driver and the keyboard and mouse.

3. B. Windows 7 and Windows Vista use the Windows Boot Configuration Data (BCD) file instead of the BOOT.INI file. This can be rebuilt with the /REBUILDBCD option.

4. B. The first step is to identify the problem. Once you have done that, you should (in order) establish a theory of probable cause, test the theory, establish a plan of action to resolve the problem, verify full system functionality, and document your findings.

5. B. The System Restore tool is used to create restore points. Backup creates backups of your hard drive. You can use Backup to create copies of your configuration (like a restore point) along with other data, but to specifically create a restore point, use System Restore. There are no Restore Point or Emergency Repair tools (although there is an emergency repair disk).

6. A. Only Windows XP uses the BOOT.INI file. Windows 7 and Windows Vista use the Boot Configuration Data (BCD) file.

7. C. Check the sleep settings for hibernation and disable those first to see if that makes a difference. If it does not, then you can begin disabling drivers and making other changes.

8. A. Windows can use restore points to roll back the system configuration to a previous state. None of the other options exist.

9. B. Pop-up blockers are used to prevent both pop-ups and pop-unders from appearing. While older browsers did not incorporate an option to block pop-ups, most newer browsers, including the latest versions of Internet Explorer, now have that capability built in.

10. A. It’s critical to keep your antivirus software up-to-date, so you should update your definitions at least once per week.

11. C. Disk Defragmenter will analyze the hard drive to determine how fragmented it is and will allow you to defragment it. There is no Disk Analyzer tool. Disk Cleanup can help you free up space by deleting unneeded files. Checkdisk (Chkdsk) can help you find problems on the hard drive, but it does not look for fragmentation.

12. B. Windows Update downloads patches for the Windows operating system. Microsoft Update downloads patches for Windows as well as Microsoft applications.

13. A. Windows Defender is an anti-malware program. It checks for harmful, or unwanted, software installed on the machine.

14. A. The Regsvr32 tool (REGSVR32.EXE) allows you to register and unregister modules and controls for troubleshooting purposes.

15. A, B, C, D. Establishing security policies and procedures, updating your operating systems, updating your applications, and updating your network devices are all good measures to take to help eliminate potential security problems.

16. A. Some viruses won’t damage a system in an attempt to spread into all the other systems in a network. These viruses use that system as the carrier of the virus.

17. B. Disk Cleanup can help you free up space by deleting unneeded files. Disk Defragmenter will analyze the hard drive to determine how fragmented it is and will allow you to defragment it. There is no Disk Analyzer tool. Checkdisk (Chkdsk) can help you find problems on the hard drive, but it does not delete files.

18. D. SFC automatically verifies system files after a reboot to see if they were changed to unprotected copies.

19. B. To open System Restore, click Start > All Programs > Accessories > System Tools > System Restore.

20. A. The figure shows Regedit, but the name of the utility has been purposely obscured.
