Which of the following statements are TRUE?
A.
The SCSI controller is connected to the IDE drives.
B.
High-volume servers typically use SCSI drives require SCSI controllers in order to function properly.
C.
The SCSI controller and the ATA controller can be mixed.
D.
The ATA controller is connected to the SCSI drives.
Explanation:
A SCSI host adapter or the IDE/ATA controller normally interfaces between the system and the hard disk drives. ATA controllers are designed to work with IDE drives and SCSI controllers are designed to work with SCSI drives. They do not mix! Although high-volume servers typically use SCSI drives, they obviously require SCSI controllers in order to function properly.
Incorrect Answers:
A: SCSI controllers are designed to work with SCSI drives.
C: ATA controllers are designed to work with IDE drives and SCSI controllers are designed to work with SCSI drives. They do not mix.
D: ATA controllers are designed to work with IDE drives.
