23-16 Chapter 23 Implementing, Managing, Monitoring, and Troubleshooting Hardware Devices and Drivers
3. Correct Answers: D
A. Incorrect: Some of the earlier versions of Windows required you to manually
edit the system Registry to resolve certain software problems; however, it is very
easy to make a mistake and render Windows XP Professional unusable when
you manually edit the Registry. Windows XP Professional allows you to manage
virtually all aspects of the system through graphical tools and command-line
tools. Whenever possible, use these built-in management tools to resolve issues
such as this.
B. Incorrect: The DirectX Diagnostic Tool can be launched from a command line
by typing Dxdiag.exe. This tool is used to review, configure, and troubleshoot
the hardware in a computer that interacts with DirectX. The DirectX Diagnostic
Tool is not used to install or update drivers for hardware devices.
C. Incorrect: Windows XP Professional is compatible with numerous legacy hardware
devices. If the specific device does not appear on the list in the Add/Remove
Hardware Wizard, verify that it is in Windows Catalog. If it is, contact the vendor
to obtain up-to-date device drivers for Windows XP Professional.
D. Correct: Windows XP Professional is compatible with many legacy video adapters,
even if they are not Plug and Play–compatible. During the installation of Windows
XP Professional, the Setup program can detect many legacy hardware
devices and then install appropriate drivers to enable them. However, Setup does
not always recognize every installed hardware device. If appropriate drivers are
not on the Windows XP Professional installation CD-ROM, you might be able to
locate compatible drivers on the vendor’s Web site.
4. Correct Answers: A
A. Correct: High-contrast display settings are well-suited to users who cannot easily
distinguish user interface elements. The correct way to enable this setting is by
using the Accessibility Options in Control Panel.
B. Incorrect: The Display properties dialog box does not have an Accessibility
Options tab. Instead, you should use the Accessibility Options dialog box.
C. Incorrect: Narrator is a useful tool for users who prefer audio to visual feedback
from the computer in response to events such as switching windows and typing
characters. However, it does not meet Dan’s needs because Dan prefers to view
the monitor directly, but requires more contrasting colors.
D. Incorrect: High-contrast settings can be enabled by holding the left-Alt and left-
Shift keys and pressing Print Screen.
