    2. Parallel port

    3. Serial port

    4. Video card

    Correct Answer = D.

    The AGP slot was designed for accelerated graphics and video processing.

  3. You have replaced a bad CMOS battery. What should you check next?

    1. COM port settings

    2. Hard drive settings

    3. Date and time

    4. BIOS version

    Correct Answer = C.

    After clearing the CMOS settings and re-entering setup, you should first check to see if the system date and time are correct.

  4. You have experienced a floppy drive failure. What error code will your POST most likely display?

    1. 301

    2. 161

    3. 601

    4. 1701

    Correct Answer = C.

    Table 2.3 identifies common POST error codes. Error code 601 identifies a floppy drive/adapter error.

  5. The computer is continuously rebooting on its own. What is most likely the problem?

    1. There is a ghost in the machine.

    2. The CMOS battery is losing its charge.

    3. You are experiencing ESD.

    4. The system is not getting enough power.

    Correct Answer = D.

    If your system continuously reboots on its own, it may not be receiving enough power from the power supply.

  6. You cannot remember your password to get into the system settings on boot-up. How can you address this? (Choose Two)

    1. Remove the CMOS battery.

    2. Use a multimeter.

    3. ‘Short' the CMOS jumper.

    4. Press Ctrl+Alt+Del.

    Correct Answers = A and C.

    Removing the CMOS battery or ‘shorting' the CMOS jumper will clear the CMOS settings, which include a previously stored password. This will allow you to re-enter CMOS and change the system settings.

  7. Label all of the components specified on the diagram in Figure 2.4.

    Figure 2.4: Baby AT motherboard.

    Answers: See Figure 2.1.

  8. Label all of the components specified on the diagram in Figure 2.5.

    Figure 2.5: ATX Motherboard

    Answers: See Figure 2.2.

  9. What information is usually found in an MSDS? (Choose Four)

    1. Microsoft systems development software

    2. Disposal instructions

    3. First-aid instructions

    4. Hazardous material-handing information

    5. Transportation instructions

    Correct Answers = B, C, D, and E.

    MSDSs contain information regarding the proper handling, disposal, and transportation of hazardous material. They also contain first-aid instructions, should an emergency or exposure to a hazard occur.

  10. Which of the following is an ATX-compatible PCI riser card that offers logic support for such technologies as audio, modem, LAN, and USB?

    1. SODIMM riser card

    2. Scalable Logic Card Interpreter (SLCI)

    3. CNR card

    4. All of the above

    5. None of the above

    Correct Answer = C.

    The CNR is an Intel-created standard that applies to riser cards. A communication network riser card is an ATX-compatible PCI riser card that offers logic support for such technologies as audio, modem, LAN, and USB.

  11. Which Intel standard allows analog I/O functions to be separate from the motherboard?

    1. SLCI

    2. NLX

    3. AMR

    4. Soft switch

    5. None of the above

    Correct Answer = C.

    This AMR specification for motherboard architecture allows analog I/O functions to be separate from the motherboard by placing them on a riser card that contains a codec chip. Intel developed the AMR standard.

  12. Of the following devices, which is used to protect electronic equipment from transient voltage or ‘spikes?'

    1. Multimeter

    2. Surge suppressor

    3. Integrated I/O port

    4. An AC compressor/decompressor

    5. None of the above

    Correct Answer = B.

    A surge suppressor is a device used to protect electronic equipment, such as computer systems, printers, modems, and monitors, from transient voltage or ‘spikes' that occur in the flow of electricity.

  13. An educated remote user calls you and states that they need you to send a replacement modem card for their laptop computer. What type of PCMCIA card will you send them?

    1. Type I

    2. Type II

    3. Type III

    4. Type IX

    5. None of the above

    Correct Answer = B.

    Type II PCMCIA cards are used for network interface cards or modems and are 5mm thick.

  14. Your company's main server computer is on fire! What type extinguisher should you use?

    1. Type I

    2. Type II

    3. Class A rated

    4. Class C rated

    5. All of the above

    Correct Answer = D.

    Computer-related electrical fires should be extinguished with an extinguisher that is rated for Class C fires.

  15. Which type of mini-PCI card must be located at the edge of the system board or docking station chassis in order to connect the card's built-in RJ11 and/or RJ45 I/O connectors directly to the mounted external RJ11 and RJ45 ports?

    1. Type I

    2. Type II

    3. Type III

    4. Type IX

    5. None of the above

    Correct Answer = B.

    Based on their design, Type II cards must be located at the edge of the system board or docking station chassis in order to connect the card's built-in RJ11 and/or RJ45 I/O connectors directly to the mounted external RJ11 and RJ45 ports.
