21. How would you advice the trainee A+ technician to install a harddrive when the system currently has a Harddrive on the primary IDE channel jumpered as Master and a CD-ROM drive jumpered as Slave? Bear in mind that there are no devices on the secondary IDE channel and that the new harddrive should be installed without having to remove the current harddrive. A. Install the new drive on the secondary IDE channel and jumper it as a cable select. B. Move the CD-ROM drive to the secondary channel and install the new Harddrive on the primary channel jumper it as Slave. C. Install the new drive on the primary IDE channel and jumper it as cable select. D. Install the new drive on the secondary IDE channel and jumper it as cable Master. |
21
Answer: A Explanation: Placing the second harddrive on a separate IDE channel would improve I/O performance Incorrect Answers: B: This will require more effort than just installing the new drive on the second IDE channel. C: We would need to remove one of the drives currently on the primary IDE channel before we can install the new drive on that channel because IDE channels can only support two drives. D: This could work. However, some harddrives require a slave to be present when the drive is configured as master. Setting the jumper to cable select will be the better option. |

26. You are a technician at . Your newly appointed trainee wants to know what RAID levels provide added performance as well as fault tolerance. What would your reply be? (Choose two) A. RAID 0 B. RAID 1 C. RAID 0+ 1 D. RAID 5 |
26
Answer: C, D Explanation: RAID 0+1 is also called mirroring plus striping. It combines the performance and redundancy benefits of RAID 0 and RAID 1. With RAID 5, data is striped at a byte level across multiple disk drives with parity information distributed among all the disks. If a single disk drive fails, the original data can be re-created by doing the reverse of the parity calculation. RAID 5 exacts a performance impact for writes because of the parity calculation, but yields a performance increase on reads. Incorrect Answers: A: RAID 0, which is also called striping, provides increased read and write performance but does not provide redundancy. B: RAID 1, which is also called mirroring, provides redundancy by duplicating the exact contents of one drive onto another. However, it has an adverse impact on read/write performance because data must be written to both drives. |

29. You are a technician at . Your newly appointed trainee wants to know how to identify an ATA/33 IDE cable from an ATA/66 IDE cable. What would your reply be? A. Cable color B. Cable pin out C. Twists in the cable D. Number of wires |
29
Answer: D Explanation: The ATA/33 cable has 40 wires, while the ATA/66 cable has 80 wires. The best way to distinguish between the cables is simply to count the wires Note: Ultra ATA/66 removes bottlenecks associated with data transfers, especially during sequential operations. Ultra ATA/66 requires a special 40-pin, 80-conductor cable that reduces noise bleed-over and improves signal integrity by providing 40 additional ground lines between each of the standard 40-pin ATA signal lines and ground lines. ATA/66 cable with 80 wires. <img src="./aplus-core/img/80pinide.gif"> ATA/33 cable with 40 wires. <img src="./aplus-core/img/40pinide.gif"> Incorrect Answers A: There is no standard for coloring the cables.. B: Both the ATA/33 cable and the ATA/66 cable use 40-pins. This enables ATA/33 and ATA/66 devices can coexists on the same cable. However, since both cables have the same number of pins they cannot easily be distinguished by pins. C: There are no twists in the cable. |
