    1. 1 MB per second
    2. 100 bytes per second
    3. 20 million bits per second

    4. hard drive
    5. bios

    Answer :B

35. This statement is in autoexec.bat:
    c:\dos\cdrom\mscdex /d:cdrom001 /l:e /m:10 /v

    This statement is in config.sys:
    device=c:\cdrom\atapicd.sys /d:cd001

    Your CD-Rom drive is not working. What is wrong?

    1. the "v" switch in autoexec.bat is invalid
    2. the device name is not the same in both files
    3. the "m" switch in autoexec.bat is set too high
    4. config.sys is not using the dos directory
    5. nothing, it should work

    Answer :B

    2. limited cable length

37. On some older SCSI adapters, the boot hard drive must be set to id#: (as a side note, some of the older IBM SCSI PCs had to have the boot hard drive set to id 6, but this question deals primarily with most other PC makes and clones)
    1. 2
    2. 3
    3. 0
    4. 9
    5. 11

    Answer :C

38. You have a PC with a SCSI adapter built into the system board It has only one connection (internal), which is used for your hard drive, CD-Rom drive, and tape drive. Your boss wants to connect a SCSI scanner to the PC, so you install a SCSI adapter with an external connection to support the scanner. Now you have a PC with two SCSI adapters. SCSI adapters normally use id# 7, which the onboard adapter is set for. The adapter you installed should: (select all that apply)
    1. use a different id
    2. use id 7 also
    3. not use an id
    4. use a different IRQ
    5. be checked for fleas

    Answer :B, D

39. You run a super wing-ding diagnostic program on your PC, and it reports that your hard drive, microprocessor, ram, and video card have seen better days. To resolve this problem you should:
    1. replace each part one at a time, rerunning the diagnostic before replacing the next part.
    2. check to see if you have a software problem
    3. replace everything at once and rerun the diagnostic
    4. get another copy of the diagnostic program
    5. run an exhaustive memory check

    Answer :B

40. Whenever you have a hardware resource conflict, it will more likely be an IRQ conflict rather than an i/o conflict because:
    1. there are alot more i/o addresses than IRQs.
    2. the bios sometimes has more of a problem controlling IRQs
    3. i/o addresses cannot conflict
    4. software tends to correct i/o conflicts
    5. software tends to mess up IRQs

    Answer :A
