Objective 2.4 Configure and Manage File Systems<br />

22-25<br />

Objective 2.4 Answers<br />

1. Correct Answers: D<br />

A. Incorrect: Basic disks cannot support spanned volumes. Regardless, spanned<br />

volumes do not improve disk I/O because data on the disk is not generally written<br />

to or read from multiple disks simultaneously.<br />

B. Incorrect: Although striped volumes are the correct choice for improving disk I/O<br />

when accessing multiple disks, basic disks cannot support striped volumes.<br />

C. Incorrect: Although dynamic disks can support spanned volumes, spanned volumes<br />

do not improve disk I/O because data on the disk is not generally written to<br />

or read from multiple disks simultaneously.<br />

D. Correct: Dynamic disks support striped volumes, whereas basic disks do not.<br />

Striped volumes combine multiple disks into a single logical volume. When files<br />

are written to or read from the volume, both disks are accessed simultaneously.<br />

When SCSI disks are used, disk I/O performance improves.<br />

2. Correct Answers: B<br />

A. Incorrect: Although both Windows Me and Windows XP Professional can access<br />

FAT partitions, FAT is not optimized for such large disk partitions.<br />

B. Correct: Both Windows Me and Windows XP Professional can access FAT32 partitions,<br />

and FAT32 can efficiently address 36 GB hard disks. For these reasons,<br />

FAT32 is the best choice for dual booting between Windows Me and Windows XP<br />

Professional.<br />

C. Incorrect: CDFS is a file system used only for CD-ROMs. It is not an option for<br />

hard disk drives.<br />

D. Incorrect: Although NTFS is an excellent choice for Windows XP Professional<br />

systems, NTFS partitions cannot be accessed from Windows Me.<br />

3. Correct Answers: B, C, E, and G<br />

A. Incorrect: Windows Me cannot support RAID 5 nor any NTFS volume.<br />

B. Correct: Windows NT Workstation 4.0 supports RAID 5 volumes across three or<br />

more disks using NTFS partitions. Windows NT Workstation 4.0 was the last desktop<br />

operating system from Microsoft to support RAID 5.<br />

C. Correct: Windows NT Server 4.0 supports RAID 5 volumes across three or more<br />

disks using NTFS partitions.<br />

D. Incorrect: Windows 2000 Professional supports NTFS, but does not support<br />

RAID 5 volumes.
