D. Reboot from the Windows XP CD and enter the Recovery Console. Disable the SCSI service with the DISABLE command. Reboot normally and let Windows XP autodetect the scanner.
8. Windows XP supports the AGP bus for what types of devices?
A. Video adapters
B. Network adapters
C. Multiport serial adapters
D. SCSI host controllers
9. When installing a Plug and Play device, Windows XP Professional prompts you for the location of the device driver. You provide the drive letter of your CD-ROM drive (the device manufacturer provided the CD). However, the installation fails. What's the likely cause?
A. Your computer supports APM but not ACPI.
B. The CD is corrupt.
C. You aren't logged on as an Administrator.
D. Plug and Play has been disabled by a group policy.
10. Approximately how many times faster can a FireWire device be than a USB device, in terms of data transfer?
1. B and C. Merely disabling the controller won't work. Uninstalling it forces Windows XP to re-detect the controller, and all connected peripherals, at the next restart. Choice D is wrong because the controller wouldn't even appear in Device Manager if it were disabled at the BIOS level. See 'Getting on the Universal Serial Bus.'
2. A and B. Just one of those facts to memorize, I'm afraid. It all depends on how the adapter's manufacturer decided to implement the driver. See 'ISDN.'
3. B and D. UDF stands for Universal Data Format. UDF has some of the features of NTFS, but it isn't the same animal. UDP stands for User Datagram Protocol, a transport-level network protocol used in TCP/IP networks. FAT32 may be used in Windows XP for writeable DVD-RAM discs. CDFS is the CD-ROM File System. Check out 'DVD.'
4. A, B, C, D, and E. The Windows operating system is becoming well known for providing several different paths to the same utility. Sometimes that's handy, sometimes it's confusing, but you never know which method the exam expects you to know. So know them all. Review 'Device Manager errors.'
5. E. Examples are MODEMLOG_56K Data Fax Modem PnP.TXT and MODEMLOG_Conexant SoftK56 PCI Modem(M).TXT. One could make a strong argument that this information really should be in the Event Viewer, so that answer is logical but wrong. The modem logging feature works just like in Windows 98, which doesn't have Event Viewer, so that may explain why Windows XP logs these activities this way. Oh, and by the way, C:\WINNT is the system folder in Windows 2000, not Windows XP! Take a look at "Analog modems."
6. C. Once you add the port driver, Windows XP can probably access the port and detect the modem's presence. Choices A and B aren't options that Windows XP allows you to perform, and choice D isn't necessary. See 'Analog modems.'
7. C. Now, let me say right away that this question presupposes some knowledge from Chapter 15, so if you haven't read that one yet, don't feel too bad about missing this one. The main point here is that Windows XP adds a very handy 'Roll Back Driver' button for just such situations. You don't need to reboot before clicking this button, and you don't need to enter Safe Mode. Choice B won't work because you already logged on after reconfiguring the system, a step that overwrites the Last Known Good configuration. Refer to 'Device Manager errors.'
8. A. AGP is for video adapters only. See 'Single display technology.'
9. C. Only an administrator can install a Plug and Play device for which Windows XP can't automatically find the driver. See 'Administrators and Plug and Play.'
10. B. 400 divided by 12 is 33.33. This is one of those questions where it's handy to be able to use the Windows calculator. Take a look at 'FireWire: USB Plus Caffeine.'

* Install, configure, and manage Infrared Data Association (IrDA) devices
* Install, configure, and manage wireless devices
* Manage, monitor, and optimize system performance for mobile users
Windows NT Workstation 4.0 was notorious for being less than completely convenient on portable computers. With the world getting more mobile every day, Microsoft wisely added two Windows 9x features to the NT platform in Windows XP: power management and Plug and Play. Windows XP provides some evolutionary advances in both areas. This chapter looks at these two technologies as well as a couple other issues of interest to notebook users: wireless devices and performance optimization through hardware profiles. (The topic of offline files and folders, also of interest to mobile computer users, gets its due in Chapter 12, as it's considered part of IntelliMirror.)
Configure Advanced Configura-tion Power Interface (ACPI)
1. You're on an airplane and asked to power down your notebook computer. Would you choose Hibernate or Standby?
2. The power management standard that Windows XP prefers is ______.
3. A group of settings for powering down disks and displays is known as a ______ in Windows XP.
