Practice Test Question: SCSI cable lengths

clipped from www.proprofs.com
1.
You replace a customer's HDD with a Single Ended SCSI system using approximately eight meters of cables in the SCSI system. After this installation the peripherals have stopped functioning. What do you suspect?
 


Single Ended SCSI systems use an unbalanced electrical signal.


Single Ended SCSI systems don't work if the total cable length exceeds 6 meters.


An improper cable insertion is the problem.


The cable length is less than the minimum allowed cable length.

- Explanation


The most probable reasons is that the total cable length is eight meters, which exceeds the allowed length. Single-ended SCSI systems have a cable distance limitation of 6m.
