1. B. The –l switch can be used with PING to specify a packet size.

3. C. Tracert works like ping but returns the different IP addresses the packet was routed through to reach the final destination.

4. A. The BOOTREC /FIXBOOT command can be used to write a new boot sector.

5. D. The screen shows the results of the NSLOOKUP GOOGLE.COM command.

6. D. The TASKLIST utility will list at the command line all running processes.

13. B. The Backup utility is provided with all versions of Windows, but it has different levels of functionality in the different versions.

14. D. The SFC command will run System File Checker. The /SCANNOW option will scan files, and SFC automatically repairs files it detects as corrupted.

15. C. The operating system boots from the active partition. Active partitions must be primary partitions, but a primary partition does not have to be active (there can be up to four primary partitions per hard drive).

16. B. There are five basic hives in the Windows Registry: HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE, HKEY_USERS, and HKEY_CURRENT_CONFIG. HKEY_LOCAL_MACHINE stores information about the computer’s hardware. HKEY_CURRENT_MACHINE, HKEY_MACHINE, and HKEY_RESOURCES do not exist.

17. C. The PING command tests to see whether you can reach a remote host on the network.

18. A. Windows Disk Defragmenter rearranges files on your hard disk so they occupy contiguous spaces (as much as possible).

Scandisk will check the hard drive for errors, and Windows Backup backs up files but does not manage their physical location.

19. B. The /MIR switch can be used with ROBOCOPY to mirror a complete directory tree.

20. D. The DxDiag utility (DirectX Diagnostics) is used to test DirectX functionality. Telnet is used to establish a remote connection, Msinfo32 shows configuration settings, and ping can let you know if a remote host can be reached.
