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.
