1. 06 9688CHO3 10 11 00 1 00 PM Page 221 F OBJECTIVES Microsoft provides the following objectives for Configuring and Troubleshooting Hardware Devices and Drivers Configure hardware devices gt This objective is necessary because someone certified in the use of Windows 2000 Server technology must understand the methods for configuring the hardware in a Windows 2000 Server computer This includes not only getting such devices to function but also getting them to function well Configure driver signing options gt This objective is necessary because someone certified in the use of Windows 2000 Server technology must understand the implications of driver signing This includes understanding how driver signing can increase system reliability protect a server against corrupted and or virus stricken device drivers and ensure that fraudulent drivers are not loaded by mistake Update device drivers gt This objective is necessary because someone certified in the use of Windows 2000 technology must be able to update the device drivers This includes knowing where to obtain new drivers what the procedures are for updating them and what the implications are of upgrading or not upgrading these drivers CHAPTER Troubleshoot problems with hardware gt This objective is necessary because someone certified C on f i gu ri n g an d in the use of Windows 2000 Server technology must be able to effectively trouble2. The three levels of driver signing are Ignore Warn and Block Ignore means that no warning will be issued when an unsigned driver is installed which could allow the installation of corrupt or unstable drivers Warn means that when an unsigned driver is installed a warning will be issued but the user will be able to con tinue with the installation or abort it Block means that no unsigned drivers can be installed on the system A warning will be issued but no possibility for override will be possible For more information see the section Configuring Driver Signing Options The utility that allows for all the main system configuration utilities to be displayed in one place is the Computer Management console For more information see the section Viewing Installed Devices 06 9688CH03 254 10 11 00 1 00 PM Page 254 Part EXAM PREPARATION APPLY YOUR KNOWLEDGE 4 5 Most hardware will be installed and configured by the Plug and Play manager The only time you will have to manually configure is for legacy devices that are not Plug and Play For more information see the section Configuring a Hardware Device A certified hardware list is available in the Hardware Compatibility List HCL This list is available both on the Internet http www Microsoft com hcl and on the Windows 2000 Server CD HCL TXT For more information see the section Configuring Hardware Devices

Devices drivers should be updated whenever a new version becomes available provided that it has been thoroughly tested by the manufacturer and if possible signed by Microsoft Updates to device drivers often fix possible bugs in the soft ware and increase reliability functionality and speed As a result the benefits are more stable access to hardware and a more reliable Windows 2000 server For more information see the section Updating Device Drivers Answers to Exam Questions 1 C Jamie needs a driver for this non Plug and Play device If she can obtain one Windows 2000 will allow her to install it When she gets the driver she will go to the Hardware Wizard to install it Although the Device manager will allow you to do many things you cannot use it to install non Plug and Play devices If she has time it would be advisable for Jamie to check for this network card on the Hardware Compatibility List to ensure that although it s not Plug and Play compatible it is certified by Microsoft for reliable use with Windows 2000 For more infor mation see the section Configuring a Hardware Device B Because Jamie cannot install unsigned drivers you know the signing option is set to Block She must set it to something that will allow her to bypass that block Answer B is the only choice that recognizes the current condition Block and provides an option that will allow her to install Warn F
