Q 21 Windows 2000 Professional supports a large number of hardware devices and drivers. Under what circumstances will a device not offer full functionality of an offered feature in Windows 2000 Professional, considering that it is listed in the Hardware Compatibility List?
A. When the manufacturer does not provide any support
B. When the device is not plug-and-play compliant
C. When the BIOS does not support the offered feature
D. When the computer is upgraded from a previous operating system
ANSWER:
C: When the BIOS does not support the offered feature. Even if a device is listed in the Hardware Compatibility List and fully supports a particular feature offered in Windows 2000, it will be unable to provide full functionality if the computer BIOS does not support it. A disabled feature in the BIOS can be another reason for an inability to provide full functionality.
A is an inappropriate choice because there is rarely any manufacturer that does not support its products. Moreover, this is not a reason for the limited functionality of any feature. B is incorrect because even when a device is not a plug-and-play device, the OS might support it. D is incorrect because the device support is independent of whether the system OS was upgraded or a clean installation was performed.
Q 22 You have a laptop computer running Windows 2000 Professional that you use on the office network as well as at home. There are some files on the network file server that you need to work on every day while in the office and at home. How will you ensure that the files on the network file server are updated every morning from your laptop when you log on to the network?
A. Copy all cached files manually to the network file server after you log on.
B. Configure the Synchronization Manager using the Logon/Logoff tab in Windows Explorer to synchronize the files when you log on.
C. Configure Manual Caching for Documents in the Sharing tab of the folder where you keep the files.
D. Configure Automatic Caching for Documents in the Sharing tab of the folder where you keep the files.
ANSWER:
B: Configure the Synchronization Manager using the Logon/Logoff tab in Windows Explorer to synchronize the files when you log on. This action ensures that when you log on to the network each morning, the files on the network file server are updated using the cached offline copy from your laptop. This option also allows you to select which files you want to copy to the file server.
A, copy all cached files manually to the network file server after you log on, is incorrect because this is not the best option and could be a cumbersome process if the number of files is large. C, configure Manual Caching for Documents in the Sharing tab of the folder where you keep the files, and D, configure Automatic Caching for Documents in the Sharing tab of the folder where you keep the files, are incorrect because these options are used when you want to offer offline copies of shared files on your computer to other users on the network.
Q 23 One of the Windows 2000 Professional computers in your office is shared on the network and is being used for storing a large number of files temporarily. For this purpose, a 10GB hard disk formatted in NTFS is used. The files are kept in the computer for some days and are then deleted to make space for newer files. Users are experiencing slow response times while accessing files from this computer. You have checked the network and all seems fine. The computer is built on a 400MHz processor and has 2GB of RAM. What can you do to resolve the slow-response problem?
A. Increase the RAM in the computer.
B. Upgrade the processor to 500MHz.
C. Run Disk Defragmenter.
D. Run the Chkdsk utility.
ANSWER:
C: Run Disk Defragmenter. Users are experiencing slow file access problems due to disk fragmentation. This usually happens when you frequently delete a large number of files from the disk. The best way to overcome the problem is to use the built-in Disk Defragmenter.
A and B are incorrect because the processor speed and the RAM in the computer are not valid reasons for the problem. Users store files only temporarily, and no processing seems to be carried out on the computer. D is an inappropriate choice because the Chkdsk utility is for scanning the disk for errors.
Q 24 A user calls you concerning a problem he's having installing a new device. Each time he runs the installation program, a message box appears, warning that an unsigned file is being installed. Which of the following settings has caused this warning message to appear?
A. Driver Signing in System properties has been set to Block
B. File Signature Verification Tool has been set to Block
C. File Signature Verification Tool has been set to Warn
D. Driver Signing in System properties has been set to Warn
ANSWER:
D: Driver Signing in System properties has been set to "Warn." Driver signing prevents installation of files and drivers without digital signatures. Digital signatures identify the manufacturer of the file and help to ensure the integrity of files. The Driver Signing settings in Windows 2000 enable you to prevent counterfeit files from overwriting legitimate ones and possibly causing problems or crashing your system. To change the way Windows 2000 handles unsigned drivers, go to the Hardware tab of the System applet, and click the Driver Signing button. Here you can choose the following verification options: Ignore (which will install all files, regardless of their file signatures), Warn (which displays a message before installing unsigned files), and Block (which prevents unsigned files from being installed).
A is incorrect because if Driver Signing has been configured to Block unsigned drivers from being installed, no warning message appears. The installation fails without warning if a file signature isn't found. B and C are incorrect because the File Signature Verification tool doesn't affect installation of such files or have options that determine how Windows 2000 deals with drivers when they are installed. It provides information on files currently installed on your system.
Q 25 You are installing a network printer on a Windows 2000 Professional workstation. The name of the server is
production_server01
and the name of the shared printer is
hplaser_12
In the following Add Printer Wizard, select the appropriate printer name.
Name /production_server01/hplaser_12 \\production_server01\hplaser_12 production_server01/hplaser_12 //production_server01//hplaser_12/lpt1:
ANSWER:
A:
The answer is the second item in the drop down box:
\\production_server01\hplaser_12
Proper syntax for entering the name of a shared printer is:
\\print_server_name\printer_share_name
Or, you can select Type the printer name, leave the fill-in box empty, and click Next to browse for your printer. You can also find the printer in Active Directory, if it has an Active Directory.
Q26 You are concerned about the memory performance of a Windows 2000 Professional workstation, and you open Task Manager to view the amount of memory being used for different operations. On the Performance tab, you see statistics on the system cache. Which of the following best explains what these statistics represent?
A. System cache is the physical RAM that can't be paged out to the hard disk and is only available to the operating system.
B. System cache is the total swap and RAM areas that are currently allocated for applications.
C. System cache is the total swap and RAM areas that are currently allocated for system operations.
D. System cache is the total number of handles, threads, and processes currently running on the system.
ANSWER:
C: System cache is the total swap and RAM areas that are currently allocated for system operations. In other words, it is the total amount of RAM being used for system operations in physical memory and the amount of memory available by swapping data to the hard disk.
A is incorrect. On the Performance tab, nonpaged kernel memory represents the physical RAM that can't be paged out to the hard disk and is available to only the operating system. The reason for this limited availability is because the operating system needs fast access to this protected area of memory and the data it contains. B is incorrect because the system cache represents only total swap and RAM for system operations, not applications. D is incorrect because the total number of threads, handles, and processes currently active are listed under the Totals section of the Task Manager's Performance tab.
Q27 You are responsible for setting up new computers on a network. You want to control the desktop settings so that users can't modify them. This is because you want all workstations running Windows 2000 Professional to have an appearance that reflects uniformity and the professionalism of the company. Which tool that ships with Windows 2000 Professional would you use to restrict user control of desktop settings?
A. User Manager
B. Microsoft Management Console
C. Display applet in Control Panel
D. POLEDIT.EXE
ANSWER:
B: Microsoft Management Console is a tool that ships with Windows 2000 Professional. Using this tool, you can install snap-ins that perform a variety of tasks and/or provide information that can be vital in troubleshooting problems. Two such snap-ins are the Default Domain Policy and the Local Computer Policy. The Default Domain Policy applies to all computers in a domain; the Local Computer Policy applies only to users on a given computer. By loading either of these snap-ins, you can control the desktop settings users are able to control.
A is incorrect because User Manager is a tool that was used only until Windows NT 4.0. User Manager has been replaced by the Local User and Groups snap-in for Microsoft Management Console, which allows you to control local users and groups but not specific settings on their desktop. C is incorrect because although the Display applet allows you to make modifications to the desktop, you can't use it to set policies that control how other users make changes. D is incorrect because the Policy Editor POLEDIT.EXE doesn't ship with Windows 2000 Professional. It has been replaced by snap-ins for the Microsoft Management Console.
Q28 Grace, a user in your graphics art department, is often creating large graphics files. As the System Administrator, you try to set reasonable disk quotas for each user in the department, but space is always an issue. Grace estimates that she usually has 10 active graphics, each about 10 MB in size. However, she is able to compress the files 90%, to about 1 MB in size. Use the following Disk Quota dialog to set an appropriate quota for Grace.
Enable quota management
Deny disk space to users exceeding quota limit
Select the default quota limit for new users on this volume
Do not limit disk usage
Limit disk space to 10 50 100 KB MB GB
Set Warning level to 9 45 90 500 KB MB GB
ANSWER:
D:
The file size calculated is based on the size of the uncompressed files. Therefore, Grace will need a quota of at least 100 MB. The other available settings are all to small to accomodate her needs.
Q29 Jennifer is sitting at Julie's computer running Windows 2000 Professional and has moved a file on the hard disk. There is a shortcut to this file on the desktop, and Jennifer calls you for help in restoring it. Assuming she has rights to modify the shortcut, how can she fix the shortcut so that it points to the moved file? Choose all that apply.
A. Double-click the shortcut. Windows 2000 Professional automatically recognizes that the file was moved or deleted. It searches the file that matches the shortcut information most closely in size, date, and type. It then asks if you want to have the shortcut point to the file or delete the file it has found.
B. Double-click the shortcut, and when Windows 2000 Professional displays a dialog box, click the Browse button. You are then able to browse your hard drive for the missing file so that the shortcut points to the new location.
C. There is no way to fix a shortcut to a file that has been deleted or moved. You need to delete the shortcut and create a new shortcut pointing to the file's new location.
D. This question cannot be answered, because Windows 2000 Professional automatically removes a shortcut from the desktop when the file to which it points is deleted.
ANSWER:
B: Windows 2000 Professional can search for a file pointed to by a shortcut icon or enable you to browse for the file. To do this, double-click on the shortcut to display a dialog box. While this dialog box shows, Windows is searching for the file that most closely matches the shortcut file in size, date, and type. At any time, you can click the Browse button to search for the missing file yourself. Doing so opens an Explorer-type window that enables you to browse files on your drives. If you don't click the Browse button and you let Windows continue searching, it provides you with several options if a closely matching file is found. You can click "Fix it" to have the shortcut point to the file, "Delete it" to delete the shortcut, or "Cancel" to leave the shortcut as it is. In addition, you can also right-click the shortcut and select Properties. This action brings up the properties of the shortcut and enables you to modify the path to the file to which this shortcut points. If all else fails, you could also delete the shortcut and create a new one that points to the new location of the file.
A is incorrect because when Windows 2000 Professional finds a file that closely matches the one in the broken shortcut, you are not given the option to delete the file that has been found. A button called "Delete it" appears on the dialog box, but it refers to deleting the shortcut from the desktop, not the file that's been found. C is incorrect because-as stated in the previous discussion-there are several ways to fix a shortcut that points to a missing file. D is incorrect because when a file is moved or deleted, the shortcut pointing to it is not automatically removed from the desktop.
Q30 Joe is in charge of a project being conducted in a department of your company. On a regular basis, he has co-op students from the local college come to the office to work on computers. He would like to be able to create new accounts for these students when they join his project and delete the accounts when they leave the project and return to school. You would like to give Joe the ability to do this, but you don't want him to be able to modify or delete existing accounts of other users in your organization. To which of the following built-in groups of Windows 2000 will you add Joe?
A. Administrators
B. Power Users
C. Limited Admin
D. Replicator
ANSWER:
B: Power Users. Users who are added to the Power Users group have the ability to create user accounts. Once created, a member of Power Users can add and remove users from the Power Users, Users, and Guest groups, create and remove local groups, and add the user accounts they create to these groups. They can modify and delete accounts they create, but they are unable to modify and delete the accounts that are created by other users (such as those in the Administrators group or other Power Users). Although it might seem that members of the Powers Users group have the same powers as members of the Administrators group, this is not the case. Power Users don't have the ability to modify Administrator or Backup Operators groups; they cannot manage security or auditing logs, load or unload device drivers, perform backups or restores of directories on the system, or take ownership of files.
A is incorrect because members of the Administrators group have significantly more capabilities than are required for this situation. Administrators have full control over the computer. The Administrators group is the only built-in group in Windows 2000 that is automatically granted every built-in right and ability in the system. C is incorrect because there is no built-in group called Limited Admin in Windows 2000. D is incorrect because actual users should never be added to the Replicator group. The Replicator group is used by the system for directory replication functions. Members of this group should be domain user accounts, which are used into log on the Replicator services of a domain controller. You should not add any account used by people to this group.
