第1题：

下列有关S-Video信号的说法中正确的是(41)。

A．S-Video信号是R，G和B三基色相分离的视频信号

B．S-Video信号是亮度与色差相分离的视频信号

C．S-Video信号电缆中传输了三路独立的视频信号

D．S-Video信号也称为全电视信号


正确答案：B
解析：本题考查模拟视频传输信号的基础知识。模拟视频信号通常可以采用三种方式传输：分量视频信号(Component Video)、复合视频信号 (Composite Video)和分离视频信号(S-Video)。高质量视频系统分别使用三路信号来表示红、绿、蓝三种图像分量或通过颜色空间变换生成的亮度-色差信号，比如YIQ和YUV信号。这种视频信号被称为分量视频。对于分色系统，由于分量视频的三个信道之间没有任何色度、亮度干扰，所以颜色再现能力最好。但需要更高的带宽和良好的同步机制。所谓复合视频，就是将所有的色度信号和亮度信号混合成一个信号传送。复合视频用于彩色电视广播，且兼容黑白电视广播。复合视频信号中亮度和色度信号是混合在一起的，所以它们之间的互相干扰不可避免。因此复合视频的颜色再现质量远比分量视频低。作为折中方案的分离视频信号即S-Video使用的是两路信号线传送视频信号，一路传送亮度信号，一路传送混合的色差信号。这样的方案避免了颜色信息与关键的亮度信息之间的干扰。显然S-Video的颜色再现质量介于分量视频和复合视频之间。

第6题：

You are the network administrator for Ezonexam.com.

You need to install Windows 2000 Professional on 75 new computers in your network. You use Setup Manager wizard to configure a fully automated installation script. file. You test the unattended installation using the fully automated installation script. file. When the installation completes you realize that the Windows 2000 Professional CD does not contain the driver for the Plug and Play video adapter used by the new computers.

You want to include the correct driver for the video adapter when installing Windows 2000 Professional.

What should you do? (Each correct presents part of the solution. Select three.)

A.Run sysprep.exe with the -pnp parameter.

B.In the UserData section of the fully automated installation script. file, specify the ProductID variable.

C.In the Unattended section of the fully automated installation script. file, set the Oem PnP Drivers Path property to the location of the video driver files.

D.In the Unattended section of the fully automated installation script. file, set the Oem Preinstall property to Yes.

E.Copy the video driver to the i386\$OEM$\$1\VidDriver.

F.Copy the video driver to the i386\$$\System32.


正确答案：CDE
C,D,E 解析：Explanation: The $OEM$ subfolder is used to hold applications, drivers, or utilities you want Setup to copy to the target computer. If Setup finds the $OEM$ folder in the root of the distribution folder, it copies all of the files found in this directory to the temporary directory created during the text portion of Setup. The OEMFILESPATH key in the answer file allows you to create the $OEM$ subfolder outside of the distribution folder. Thus options C, D and E should enable you to include the correct driver for the video adapter.

Incorrect answers:
A: Sysprep.exe with the -pnp parameter is the Mini-Setup wizard that detects new or different Plug and Play devices on the destination computer and disables those that were used on the master computer but not found on the destination computer. You might want to use the -pnp switch to enable legacy device detection or to re-enumerate the devices on the destination computer. Using this switch adds a few extra minutes to the end-user's experience in order to do a complete hardware redetection. However, this is not what is required in this case.

B: The ProductID key specifies the Microsoft Product Identification (Product ID) number. This parameter sets the Product ID for all computers installed using this unattended text file to the same value. Specifying the ProductID variable will not ensure that you have the correct driver for the video adapter included in the installation.

F: The video driver should be copied to the i386\$OEM$\$1\VidDriver instead.
