b. The HCL (Hardware Compatibility List) is a list of hardware supported by Windows 2000 Professional.

d. FAT32 is supported by Windows 2000 Professional and by Windows 98, but not by Windows NT 4.0.

b. The HPFS filesystem is supported only by Windows NT 3.51 and earlier and by OS/2.

a, b. Windows 2000 Professional can convert FAT or FAT32 to NTFS. NTFS partitions cannot be converted to other formats.

d. Windows 3.11 cannot be upgraded to Windows 2000 Professional; a clean installation of Windows 2000 Professional would be required.

b. Setup Manager can create an unattended installation file. UNATTEND.TXT (choice d) is a typical name for the unattended installation file.

b, d. The System Preparation Tool creates a generic system for duplication; it does not perform the actual duplication. It also creates a mini-Setup Wizard to personalize each system.

c. The upgrade.exe /slip command integrates a service pack into the installation files for use during installation.

a, c, d. MMC consoles can be used to manage disks, view system information, and view error and event logs; printers (choice b) are managed using the Printers Control Panel.

b. NTBACKUP can schedule regular backup jobs. Task Scheduler (choice a) schedules applications, but is not intended for backups.

b. Modems are configured using the Phone and Modem Control Panel applet.

a. Virtual memory is managed using the System Control Panel applet.

a. The HKEY_CLASSES_ROOT registry subtree stores file associations.

b. The HKEY_LOCAL_MACHINE registry subtree stores information loaded from a hardware profile.

a. REGEDT32 is Microsoft’s preferred registry editor.

b. REGEDIT is able to search the entire registry for a value.

a. Basic disks include primary and extended partitions.

a, c. Windows 2000 can convert basic to dynamic disks. Dynamic disks cannot be converted to basic (choice b) without repartitioning. Windows 2000 can also convert FAT partitions to NTFS partitions. NTFS partitions cannot be converted to FAT without reformatting.

a, d. Primary partitions on basic disks and simple volumes on dynamic disks can be bootable.

a. The boot partition contains the WINNT folder.

b. The system partition contains the NTLDR boot loader.

d. None of these volumes provide fault tolerance. Fault-tolerant disk configurations, such as mirrored volumes and disk striping with parity, are supported by Windows 2000 Server.

c. A striped volume interleaves data between two or more physical disks.

b. A spanned volume can be extended. A striped volume (choice c) cannot be extended.

a, b, c. FAT, FAT32, and NTFS volumes can be defragmented with the Disk Defragmenter snap-in.

a, c. Normal and incremental backups clear the archive bits; differential and copy backups (choices b and d) do not.

c. Zero cannot be used in the first or last octets, so this is an invalid address.

a. DNS (Domain Name Service) resolves IP hostnames to IP addresses.

b. DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses to clients.

a, c. SLIP (Serial Line Internet Protocol) and PPP (Point-to-Point Protocol) are dial-up protocols.

b. Print Device refers to a hardware printer.

b. Performance Console can display a graph of CPU usage over time.

a. Safe mode may allow you to boot and correct the problem. VGA mode (choice b) would not be effective because the problem happens in the real mode boot phase, and therefore probably does not involve the video card or drivers.

d. None of the above. The machines have sufficient RAM and disk storage. Although they do not have CD-ROM drives, you can install from a shared directory on the network or a local copy of the I386 directory.

b. The two machines with 16 MB of RAM will require a memory upgrade before installing Windows 2000 Professional.
