BASIC DISKS CANNOT SUPPORT SPANNED VOLUMES

1.

Correct Answers: D

A. Incorrect:

Basic disks cannot support spanned volumes. Regardless, spanned

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

to or read from multiple disks simultaneously.

B. Incorrect:

Although striped volumes are the correct choice for improving disk I/O

when accessing multiple disks, basic disks cannot support striped volumes.

C. Incorrect:

Although dynamic disks can support spanned volumes, spanned vol-

umes do not improve disk I/O because data on the disk is not generally written to

or read from multiple disks simultaneously.

D. Correct:

Dynamic disks support striped volumes, whereas basic disks do not.

Striped volumes combine multiple disks into a single logical volume. When files

are written to or read from the volume, both disks are accessed simultaneously.

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