You work as a help desk support technician at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows 2000 Server and all client computers run either Windows XP Professional or Windows 98.
A Domain.com user named Andy Reid works on a Windows 98 client computer named Certkiller -WS271. The new Domain.com policy states that all client computers are to be upgraded to Windows XP Professional. You upgrade Andy Reid’s Certkiller -WS271 client computer to Windows XP Professional. While performing the upgrade on Certkiller -WS271, you discover that the screen resolution is 640 x 480 and 16 colors.
To fully take advantage of the Windows XP Professional functionality Andy Reid wants to view the background pictures and the GUI that Windows XP Professional makes available. Now you need to change the resolution and add more colors so as to enable Andy Reid to take advantage of the Windows XP Professional functionality. However, you are unable to do so.
What should you do to enable Andy Reid to view the background pictures properly?

A.
Install the original Windows 98 video card’s driver.

B.
Restart Certkiller -WS271.

C.
Install the correct driver for the video card.

D.
Restart Certkiller -WS271 with the Last Known Good Configuration.

Explanation:
In this case where the computer has been upgraded successfully but you are unable to modify screen resolution, it means that the original Windows 98 driver for the video card is incompatible with Windows XP Professional and that Windows XP Professional does not have the correct built-in driver. This means that installing the original video card driver will not work. You should rather be installing a Windows XP Professional version of the driver on Certkiller -WS271 Incorrect Answers:
A: In this case where the computer has been upgraded successfully but you are unable to modify screen resolution, it means that the original Windows 98 driver for the video card is incompatible with Windows XP Professional and that Windows XP Professional does not have the correct built-in driver. This means that installing the original video card driver will not work.
B: Restarting Certkiller -WS271 would not enable you to change the desktop settings.
D: The Last Known Good Configuration stores the Registry and driver setting that were in place when the computer was last started successfully. However, the computer has been upgraded and this option will not address the problem as the previous configuration would include the same driver.
