Practice Questions

Question 1	Christopher is the administrator of a medium- sized (about 500 machines) Windows 2000 network for an engineering firm. The previous administrator did a fairly good job of getting Windows 2000 rolled out in the organization, including breaking up each department into OUs. However, no matter what the administrator tried, one or two computers in the production department ceased to operate properly on a daily basis. You suspect the cause might be that the layout personnel have a tendency to experiment with new hardware. What can you do to help prevent future down time on these computers? A. On each machine, set the driver signing behavior to Block. B. From Active Directory Users and Computers, create a GPO and link it to the production department's OU. Configure driver signing in the GPO for Ignore. C. From Active Directory Users and Computers, create a GPO and link it to the production department's OU. Configure driver signing in the GPO to Block. D. Remove all user accounts in the production department's OU from the Users group to the Guest group .
A1:	Answer C is correct. The best option in this case is to create a GPO linked to the production department's OU and configure the driver signing behavior for Block. You are not told how many machines are part of the production department, but in a Windows 2000 Active Directory domain, you should always strive to apply policies via Group Policy Objects instead of manually configuring them. Thus, answer A is incorrect. Configuring a GPO with the Ignore option would not be an optimal solution because all drivers (signed or not) could then be installed. When the Block behavior is set, unsigned drivers cannot be installed. Thus, answer B is incorrect. Moving the users' accounts out of the Users group and into the Guest group would fix the problem but would likely cause additional, unnecessary problems. Thus, answer D is incorrect.
Question 2	Hannah works as a help desk support technician for a large organization. Recently, she received a phone call from a user who stated that his newly installed scanner wasn't working. When instructed to look at Device Manager, the user reported back that the icon next to the scanner looked normal except that it had a yellow exclamation point on it. What should Hannah have the user do to correct the most likely problem with the scanner? A. Manually assign resources for the device, because it is having a resource conflict with another device. B. Remove the device from the system and do not try to use it again. Devices that show this icon are incompatible with Windows 2000 and should not be used. C. Install the device drivers from the installation disks or from files downloaded from the manufacturer's Web site. D. Enable the device for use in the current hardware profile.
A2:	Answer C is correct. The best course of action is to install the device drivers either from the setup disks or from files downloaded from the manufacturer's Web site. Devices that display this icon are typically not enabled due to missing or corrupted drivers. Manually assigning resources to the device will not correct the situation and is not possible because the device is not currently using any resources. Thus, answer A is incorrect. Devices that are experiencing a resource conflict display the yellow question mark with a red X, and devices that are disabled show either a normal icon with a red X (disabled by the user) or a normal icon with a yellow exclamation point (disabled by Windows). In this case, the device is displaying a normal icon with a yellow exclamation point; thus answers B and D are incorrect.
Question 3	You are training a new help desk support worker. During the course of your discussions, the topic of digitally signed device drivers comes up. When asked about why digitally signed device drivers are important, what will you not tell your new employee because it is not true? A. Digitally signed device drivers have passed rigorous testing by the WHQL and therefore should provide a high degree of reliability. B. Digitally signed device drivers are protected against changes to the driver files since signing by the manufacturer. C. Digitally signed device drivers are the only type of driver files that are found on the Windows Update Web site or Windows 2000 CD-ROMs. D. Digitally signed device drivers can't be installed unless a certificate authority has been set up on your network.
A3:	Answer D is correct. The other three statements are true concerning digitally signed device drivers. Because the certificate used to sign the file is traceable to a third-party certificate authority, such as VeriSign, there is no need for any further certificate services to be in place. If you wanted to issue digitally signed drivers to your customers, you would need a certificate authority in place on your network, preferably with a root certificate issued by a third party. When a driver has been digitally signed, it has been certified to pass the rigorous testing done by the WHQL. Thus, answer A is incorrect. By digitally signing a driver file, it is protected against all changes since it was signed. Thus, answer B is incorrect. You will only find digitally signed drivers on the Windows Update Web site or the Windows 2000 CD-ROM, thus answer C is incorrect.
Question 4	Austin is using Device Manager to gather information about a particular server in his company. Which of the following items will he be able to gather information on using Device Manager? [Check all correct answers.] A. Resource settings for a specific device B. A list of all interrupts currently being used on the computer C. The status of a particular device, such as enabled or disabled D. Information about specific drivers installed for a particular device
A4:	Answers A, B, C, and D are correct. Using Device Manager, Austin will be able to gather all this information and more.
Question 5	Chris is an administrator for her organization. Two of her servers have hardware devices that recently have had updates issued for their drivers. Where can Chris go to install the updated device drivers? A. System Information B. Device Manager C. Add/Remove Programs applet of Control Panel D. Services MMC snap-in
A5:	Answer B is correct. Chris can install the new device drivers from Device Manager. To install the new drivers, she must right-click the device to be updated and select Properties. She then must click the Driver tab and click Update Driver. The System Information utility allows her to quickly determine many facts about your computer, but will not help her install an updated driver. Thus, answer A is incorrect. The Add/Remove Programs applet is used for installing programs and configuring Windows components , not for installing drivers. Thus, answer C is incorrect. The Services MMC snap-in is used to configure and control the services running on a computer, not to install drivers. Thus, answer D is incorrect.
Question 6	Andrea recently acquired a new modem for her Windows 2000 computer. The new modem is not Plug and Play compatible. How will Andrea go about installing the new hardware device on her computer? A. Use Device Manager to install the new hardware device. B. Use the Phone and Modem Options applet of the Control Panel. C. Install the device into the computer. Windows 2000 will detect and automatically install the device the next time it is started. D. Use the Add/Remove Hardware applet of the Control Panel.
A6:	Answer D is correct. Non-Plug and Play hardware must be added via the Add/Remove Hardware applet of the Control Panel. All drivers to be installed should be Windows 2000 compliant. Device Manager will not assist in installing new hardware directly. Thus, answer A is incorrect. The Phone and Modem Options applet of the Control Panel can be used to configure dialing rules and modem settings after a modem has been successfully installed. Thus, answer B is incorrect. Only Plug and Play hardware can be installed physically and have Windows 2000 automatically install and configure the device and drivers. Thus, answer C is incorrect.
Question 7	Which of the following driver signing behaviors will not prompt the user for action when installing new device drivers and could lead to system instabilities? A. Ignore B. Block C. Silent D. Quiet
A7:	Answer A is correct. When configured for Ignore, Windows 2000 ignores and silently installs all drivers regardless of their digital signature status. This could allow unsigned drivers to be installed on a computer and subsequently lead to problems such as lockups or instability. The Block behavior automatically blocks all unsigned drivers and does not display or prompt for feedback to the user. Thus, answer B is incorrect. Quiet and Silent are not valid driver signing behavior options. Thus, answers C and D are incorrect.
Question 8	Andrea noticed that her tape drive backup unit stopped responding last night when she tried to use it. When she asks you for help, you instruct her to open Device Manager and report to you the icon displayed next to the tape drive unit. She tells you that a yellow question mark with a red X is next to the device. What should you do to correct the problem? A. Manually assign system resource settings to the tape drive because it is obviously experiencing a conflict. B. Attempt to reinstall the device driver because it might have become corrupted. C. Enable the device because someone has manually disabled it. D. Replace the tape drive because it has become faulty.
A8:	Answer B is correct. In most cases, when a yellow question mark with a red X is displayed, there is a problem with the drivers. The drivers might not be installed or might be incorrectly configured. A resource conflict is indicated by normal icon with a yellow exclamation point, thus answer A is incorrect. A device that is manually disabled will have a normal icon with a red X, which is not the case. Thus, answer C is incorrect. A faulty tape drive would most likely not give any indication in Device Manager. Thus, answer D is incorrect.
Question 9	Jeff is the administrator of a Windows 2000 network. One of Jeff's critical file servers just experienced a sudden failure of its network adapter. While Jeff waits for the delivery of a new network adapter from the manufacturer, he takes the network adapter out of an old server sitting in storage and installs it in the critical file server. When Jeff restarts the server, he sees that the network adapter he just installed is not recognized by Windows 2000 as being Plug and Play. What must Jeff do to get the newly installed network adapter operating so he can get the file server back on the network? A. Jeff will not be able to get this adapter working because no non “Plug and Play devices are supported under Windows 2000. B. Jeff should download a BIOS upgrade for the adapter, which will make it Plug and Play compatible. Then he must restart the server. C. Jeff should go to the Internet, download a Windows 2000 compatible driver for the adapter, and manually install it through the Hardware Wizard. D. Jeff should go to the Internet, download a Windows 2000 compatible driver for the adapter, and manually install it through Device Manager.
A9:	Answer C is correct. Jeff needs a driver for this non “Plug and Play device. If he can obtain one, Windows 2000 will allow him to install it. When he gets the driver, he will go to the Hardware Wizard to install it. If he has time, it would be advisable for Jeff to check for this network card on the HCL to ensure that, although it's not Plug and Play compatible, Microsoft certifies it for reliable use with Windows 2000. Non “Plug and Play devices can still be used in Windows 2000; they require that an administrator configure their resources manually. Thus, answer A is incorrect. Flashing the BIOS on the network adapter will not make it Plug and Play compatible. Thus, answer B is incorrect. Although Device Manager allows you to do many things, you cannot use it to install non “Plug and Play devices. Thus, answer D is incorrect.
Question 10	Rick is the network administrator of a small Windows 2000 network consisting of 5 Windows 2000 servers and 45 Windows 2000 Professional clients. He is currently operating in a peer-to-peer workgroup. Every week, Rick must reinstall two or three of his Windows 2000 client computers due to sudden corruption and instability of the operating system. Rick is certain that the problems are created by users who are installing unsigned drivers for their hardware, thus creating instabilities and system failures. What can Rick do to prevent all unsigned drivers from being installed on his Windows 2000 clients , regardless of which user is logged in to the computer? A. Rick should configure a Group Policy Object that sets driver signing to Ignore, link it to the OU that houses his Windows 2000 Professional clients, and then refresh Group Policy on his network. B. Rick should log on to each computer using his administrative account and configure driver signing to Ignore. He should select to apply this setting to all users of the computer. C. Rick should log on to each computer using his administrative account and configure driver signing to Block. He should select to apply this setting to all users of the computer. D. Rick should remove all of his users from the Users group and make them members of the Guest group.
A10:	Answer C is correct. Because Rick's network is operating as a workgroup and not using Active Directory, Rick needs to configure the settings for driver signing locally on each computer from the System applet of the Control Panel. Rick does not have Active Directory on his network and configuring the Ignore setting would not accomplish the goal if he did have AD, thus answer A is incorrect. Configuring driver signing to Ignore does not prevent users from installing unsigned drivers. Thus, answer B is incorrect. Placing all users into the Guest group will cause more problems than it fixes, including severely hampering Rick's users from being able to carry out all of the normal daily tasks that they need to get done. Thus, answer D is incorrect.
