A SCSI HDD with shunts on the first and third jumpers has which SCSI ID assigned?

In SCSI configuration, the jumpers on the hard disk drive (HDD) play a crucial role in determining the SCSI ID, which uniquely identifies each device on the SCSI bus. Each jumper corresponds to a specific binary value based on its position.

When a SCSI HDD has shunts on the first and third jumpers, it reflects the binary representation that corresponds to these positions. Each jumper position can typically represent a particular bit in a binary number, where:

• Jumpers in the first position represent a value of 1,

• Jumpers in the second position represent a value of 2,

• Jumpers in the third position represent a value of 4,

• And so on.

In this case, with jumpers on the first (1) and third (4) positions, you would calculate the SCSI ID by adding these values together:

1 (from the first jumper) + 4 (from the third jumper) = 5

Therefore, with the shunts on the first and third jumpers, the SCSI ID assigned is indeed 5. This is why the option corresponding to 5 is the correct answer.
