1.

Correct Answer = D

If you are troubleshooting a “dead” computer, first verify that there is electricity coming from the AC wall outlet.

2.

Correct Answer = D

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

3.

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.

Correct Answer = C

Table 15.3 identifies common POST error codes. Error code 601 identifies a Floppy Drive/Adapter Error.

5.

Correct Answer = D

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

6.

Correct Answers = A and C

Removing the CMOS battery or “short” the CMOS jumper will clear the CMOS settings, which include a previously stored password. This will allow you to reenter CMOS and change the system settings.

7.

Answers: see Figure 15.1.

8.

Answers: see Figure 15.2.

9.

Correct Answers = B, C, D, and E

A Material Safety Data Sheet (MSDS) contains information regarding the proper handling, disposal, and transportation of hazardous material. It also contains first aid instructions should an emergency or exposure to a hazard occur.

10.

Correct Answer = C

The Communication and Network Riser (CNR) is an Intel-created standard that applies to riser cards. A CNR card is an ATX-compatible PCI riser card that offers logic support for such technologies as audio, modem, Local Area Network (LAN), and USB.

11.

Correct Answer = C

This Audio Modem Riser (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 (compressor/decompressor) chip. Intel developed the AMR standard.

12.

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.

Correct Answer = B

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

14.

Correct Answer = D

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

15.

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 RJ-11 and/or RJ-45 I/O connectors directly to the mounted external RJ-11 and RJ-45 ports.
