Answers to Exam Prep Questions
-
C. Flicker and distortion on the monitor are caused by an inappropriate refresh rate. Adjusting the color depth or the resolution to lower values will not address the flicker and distortion. The color scheme only changes the look of the windows and fonts on the desktop.
-
A and D. Windows Vista Home Basic does not provide support for Windows Vista Aero. The specifications to support for Windows Vista Aero are as follows:
- 1GHz 32-bit or 64-bit processor
- 1GB RAM
- Video graphics adapter with a minimum of 128MB video RAM
- DirectX 9–class graphics processor
- Windows Display Driver Model (WDDM)–compatible driver
- Pixel Shader 2.0 in hardware
- 32-bit per pixel color depth
-
B and D. The two requirements for different Parental Controls are that each user must have a separate, password-protected standard user account. If you created each user as an administrator, you could not assign Parental Controls to those accounts, and even if you could, the users could simply turn off the Parental Controls. Special Permissions are a collection of nonstandard NTFS permissions on the application executable itself. This would not limit or control the websites that the users could access, but it might disable IE's use altogether.
-
A. You are being prompted for the administrator password because you have logged on to a standard user account and are required to provide proper credentials to access the elevated privilege required for most configuration changes. The Power Users group provides limited elevated privilege and does not allow you to access the vast majority of configuration dialogs without administrator credentials. The Power Users group is not available in Windows Vista. The Remote Desktop Users group provides for the use of the remote Desktop Connection to this computer and will not allow you to access the configuration dialogs without administrator credentials. You are already logged on locally. This rights assignment does not address the credentials prompt issue.
-
C. The Easy Transfer Wizard helps you transfer data from computers running Windows 2000, Windows XP, or Windows Vista to Windows Vista computers. It is useful in transferring the following types of files:
- User accounts
- Files and folders
- Program data files and settings
- Email messages, settings, and contacts
- Photos, music, and videos
- Windows settings
- Internet settings
Programs and applications are not transferred using this tool.
-
B and C. You need appropriate share and NTFS permissions to read and write to the file on the remote computer. The share permission of Allow—Change grants R W X D. The NTFS permission of Allow—Modify grants R W X. Together, the effective permissions for the network user are R W X, which satisfies the objectives. The Standard User Analysis tool reports only and does not make any permissions changes. It doesn't matter which account you log on as; the requirements are that you must have change and modify to be able to read and write to the file. The administrator also requires these permissions and doesn't necessarily have these permissions.
-
A. Defragmenting the hard drive improves the performance of the computer. Disabling ReadyBoost and reducing the size of the pagefile both decrease the performance of the computer. Running the video-editing application with elevated privilege does not improve performance of the computer.
-
A and B. Installing and configuring the game applications to run on a RAID 0 disk array will dramatically improve the read and write disk performance. ReadyBoost caches the contents of the pagefile, which is used when you have consumed too much RAM, onto much faster nonvolatile RAM, getting it off the slow hard drive. This also improves the performance of the RAM-intensive game application. Parental Controls would be used to disallow the use of the games but cannot control their performance. Moving the pagefile off the C: drive typically improves performance. Ensuring that the pagefile is located on the C: drive usually decreases performance.
-
C. The Windows Media Audio Variable Bit Rate Mode uses a lower bit rate when a recording has fewer sounds. This reduces the file size and enables you to pack more songs onto the CD. This also provides a pretty good recording, but not the best. Burning at a slower speed does not reduce file sizes, but it does help to ensure a more reliable disk. Compression on the hard disk will not help when you burn the songs to the CD. The files would have to be decompressed to get them off the hard disk. Windows Media Audio Lossless mode maximizes the quality and file size of the songs. This would not satisfy the requirements.
-
B. To connect a Media Center PC to a TV, you need a Media Center Extender. Microsoft Xbox 360 is a Media Center Extender. The Media Center Extender must connect to the Media Center PC over a network connection, and the appropriate firewall exceptions must be enabled. Disabling firewall exceptions will not help you connect the Media Center Extender to the Media Center PC. The network projector would be used to project the media content onto a wall or projection screen, not a TV. The Sync option is to connect and sync cameras and other handheld or disconnected devices with Media Center, not connect to Media Center Extenders.
