Answers:

1) Choice b is correct. When Windows XP Professional is installed, the default desktop displays only the Recycle Bin icon. To cause the My Computer, My Network Places and My Documents icons to appear on the desktop, you can right-click the taskbar, select Properties and enable Classic Start menu on the Start Menu tab. Alternatively, you can open Control Panel, start the Display program, select the Desktop tab, click Customize Desktop and enable the appropriate icons on the General tab of the Desktop Items page. If you enabled the desktop icons by performing these actions, then switching between the new and Classic Start menu styles would have no effect on the visibility of those shortcuts.

Enabling the Use Windows classic folders option on the General tab of Folder Options in Windows Explorer would prevent the contents of all folders from behaving like Web pages. Enabling Display simple folder view in Explorer's Folders list on the View tab of Folder Options in Windows Explorer would enable new behavior when a folder was selected in the left pane in Windows Explorer; the folder would expand in the left pane and simultaneously display its contents in the right pane. You do not need to enable Show Desktop Icons immediately after the installation of Windows XP because this option is enabled by default. Reference:WXPHSC, Search, "desktop icons," "To add a desktop icon."

2) Choice a is correct. Typically, when you insert a card into a computer that is running the Windows XP Professional operating system, the system detects the card and attempts to install drivers. If a problem occurs, then it might be attributed to the fact that the operating system cannot find the appropriate drivers, thereby preventing the devices from working properly. Another possibility might be that the operating system has installed inappropriate drivers. If such a situation exists, then you should open Device Manager, right-click the device, open its Properties sheet and click either Update Driver or Reinstall Driver. When prompted, you should specify the location, such as a floppy disk, where the operating system can find the manufacturer's driver.

The scenario stipulates that you rebooted the computer once; doing so again is unlikely to restore the functionality of the devices. You are not required connect a modem by using cables unless the modem is external. The modem in this scenario is internal; thus, you cannot perform this action. If you are using an external PS2 mouse, then obtaining a PS2-to-USB adapter and connecting the mouse to a USB port would have no effect on the modem, which may require a COM port. Windows XP is a Plug and Play operating system, and it would be able to assign the appropriate hardware settings to a PC card modem without creating a conflict with the computer's built-in COM port. Reference:WXPRK, Contents, "Part II Desktop Management," "Ch 9 Managing Devices," "Device Installation," "Installing Drivers." WXPRK, Contents, "Part IV Networking," "Ch 22 Configuring Telephony and Conferencing," "Configuring Modems."

3) Choice a is correct. The encryption of files and folders through Encrypting File System (EFS) is supported only by the NTFS file system. Encrypted files that are copied to a non-encrypted folder retain their encryption, provided that the folder resides on a volume that has been formatted with NTFS 5.0 or later. The FAT file system does not support encryption; therefore, copying an encrypted file to a FAT file system would decrypt the file. Folders cannot be converted to NTFS. Reference:WXPRK, Contents, "Part III Security," "Ch 17 Encrypting File System," "Overview of EFS."WXPRK, Contents, "Part III Security," "Ch 17 Encrypting File System," "Troubleshooting EFS," "Encrypted File Is Unencrypted When Copied or Moved."

4) Choice b is correct. Three standard printer permissions are available in Windows XP Professional: Manage Printers, Print and Manage Documents. When you assign the Allow - Manage Printers permission to a user's account, that user's account is automatically assigned the Allow - Print permission. Additionally, that user has the ability to take ownership of the printer and to assign permissions to other users. When you assign the Allow - Manage Documents permission to a user's account, that user has the authority to manage print jobs submitted by other users. In this scenario, Jennifer and Eric should be assigned the Allow - Manage Printers and Allow - Manage Documents permissions so that they can fully manage the shared printer on Jennifer's Windows XP Professional computer. All other users in the domain should be assigned only the Allow - Print permission. The Print permission allows a user to print and manage his or her own print jobs. To allow the users any additional permissions would grant them more authority than they require. Jennifer and Eric could assign more granular permissions to users if necessary. All users in a domain automatically belong to the Domain Users group. Members of Domain Users, by default, belong to the Users group on all Windows XP Professional computers in the domain. Reference: WXPHSC, Search, "Security permissions for printing."

5) Choice d is correct. All retail versions and editions of Windows XP must be activated within 30 days of the installation. You can activate an installation either by connecting to the Internet and selecting the appropriate command on the Start menu or by contacting a Microsoft Clearing House representative. You cannot attribute the logon failures experienced by these users to password expiration. By default, passwords expire only after 42 days; this option is set both in the default Domain Policy Group Policy Object (GPO) in a Windows 2000 domain and in the default local GPO.

The scenario stipulates that only those users who received computers on which the Windows XP Professional operating system was installed are unable to log on. Because the operating system has not been activated with Microsoft Clearing House, these users would not be able to use their local accounts to log on to their Windows XP Professional computers. The scenario does not stipulate whether a GPO that enforces an account lockout policy has been configured. Furthermore, such a policy would not prevent authorized network users from logging on to their computers or to their respective domains. It is not necessary to reinstall the Windows XP Professional operating system on those 25 computers. If you did so, then you would still be required to activate the software within 30 days. Reference: WXPRK, Contents, "Part I Deployment," "Ch 1 Planning Deployments," "Planning Installations," "Planning for Windows Product Activation." TechNet, Search, "Deploying Windows XP Part I: Planning," "Deployment Overviews and Guidelines." TechNet, Search, "Microsoft Product Activation," "Evaluate."

6) Choice a is correct. Remote Assistance is a Windows XP Professional feature that can be used to provide support for users at remote locations whose computers are running Windows XP Professional. A user should send an invitation through MSN Messenger, as an e-mail message attachment or in a file in order to initiate a Remote Assistance session. When you accept the invitation, a connection to the remote computer's desktop will be established automatically. Remote Assistance relies on MSN Messenger, which requires an Instant Messaging server to enable users to communicate. This server does not have to be the Instant Messaging server that provides those services for Internet users who have .NET Passport. In this scenario, the InterConn network is not connected to the Internet. However, e-mail services are provided by Exchange 2000 Server, which supports instant messaging. To provide Remote Assistance support to the users on the InterConn network, you should create a virtual Instant Messaging server on an Exchange 2000 Server computer, install the version of MSN Messenger that is bundled with Exchange 2000 Server, and configure MSN Messenger on all Windows XP computers to use that server for Instant Messaging connectivity. Remote Assistance will then work.

The latest version of MSN Messenger that is available on the Microsoft Web site cannot be configured to use an arbitrary Instant Messaging server. This version works only with one Instant Messaging server that Microsoft provides access to on its Web site. Adding the domain user accounts of the technical support personnel to the list of Remote Desktop Users on the Remote tab of System Properties in Control Panel is related to Remote Desktop connections. In this scenario, you must establish Remote Assistance connections, which are performed under the security context of the current user on the remote computer. Therefore, Remote Assistance connections do not require any additional configurations on user accounts, and no additional permissions for file system resources are required. The Network Service folder contains a user profile for a special account that is used to provide the security context for some of the services that run on Windows XP computers. This user account is irrelevant to the task presented in this scenario. Reference: TechNet, Search, "Chapter 11 - Instant Messaging and Presence Monitoring," "Exchange 2000 Server Planning and Installation."

7) Choice a is correct. Processes can belong to one of six priority classes: Realtime, High, AboveNormal, Normal, Low and BelowNormal. The higher the assigned priority relative to priorities of other concurrent processes, the more a process will monopolize processor time. In such a situation, the processes with lower priorities lose required processor time and, consequently, might slow down significantly or even become inoperable. Typically, all applications run with a priority of Normal. In this scenario, all applications, with the exception of the CAD application, should be run with a priority of Normal. To ensure that these applications receive adequate processor time, you should reduce the base priority of the CAD application. To temporarily adjust the base priority of an application at run time, you can right-click the corresponding process in Task Manager and select the appropriate priority. In this scenario, you might choose to run the CAD application with a priority of Low or BelowNormal. To permanently adjust the base priority of an application, you can use a command, such as start /belownormal program_name. The application will run properly, but its threads will receive a lesser portion of the CPU's time.

Application priorities work as they are intended only in situations where one or more applications are assigned higher priorities than other applications. If the priorities of all applications were reduced or increased, then you would experience no change in performance.
