Practice Questions for the A+ Exams
1. You have been asked to install an IDE disk to a personal computer. This will
be the only diskin the computer connected to the primary channel. How
would you set the jumper?
❍ A. Master
❍ B. Slave
❍ C. Cable Select
❍ D. Auto
Answer A is correct. A single diskis connected to the primary channel and
acts as a master disk.
2. Which of the following is the most important factor when selecting a memory
module to upgrade memory in a personal computer?
❍ A. The module has the highest memory available in the market.
❍ B. The module is built with state-of-the art technology.
❍ C. The module is compatible with the system bus.
❍ D. The module can double the system memory.
Answer C is correct. The most important factor when selecting a memory
module is to verify that the module is compatible with the system bus on the
motherboard.
3. Which of the following is the name for the diagnostic process built into
motherboards?
❍ A. POST
❍ B. CMOS
❍ C. BIOS
❍ D. DHCP
Answer A is correct. The POST is the diagnostics program built into all motherboards.
POST checks the functionality of all the hardware components of
the motherboard.
4. You have just disconnected a hard diskfrom a computer and detected a red
stripe on the data cable. What is the purpose of this red stripe?
❍ A. It indicates the last pin of the cable.
❍ B. It indicates the first pin of the cable.
❍ C. It indicates that the cable was tested by the manufacturer.
❍ D. It indicates the top end of the cable.
Answer B is correct. The red marking on the data cable indicates pin number 1.
5. Which of the following is the most important precaution you should take
while working on internal parts of the computer? Select two answers.
❏ A. Turn off the power supply.
❏ B. Disconnect the power cables from all drives.
❏ C. Disconnect the power cable from the motherboard.
❏ D. Wear a properly grounded antistatic wrist strap.
Answers A and D are correct. You must turn off power to prevent shocks and
wear a properly grounded antistatic wrist strap when working on internal
parts of a computer. Semiconductor devices on the motherboard and adapter
cards are very sensitive to static electricity.
6. You have just replaced a malfunctioning motherboard in a computer with a
brand new one. You want to make sure that the new motherboard is functioning
well before you connect other components such as the networkadapter and graphics card. Which of the following methods can be used to
test the basic functionality of the motherboard?
❍ A. POST
❍ B. Beep codes
❍ C. Successful boot
❍ D. BIOS
Answer B is correct. Beep codes will usually indicate whether there is any
problem with the basic functionality of the motherboard. Different manufacturers
of BIOS software have different beep codes, and you must refer to the
motherboard user manual for the exact meaning of a particular beep code.
7. Which of these methods can be used to test a 10/100 Mbps networkport
built on the motherboard without connecting it to the network?
❍ A. Multimeter
❍ B. Loopback adapter
❍ C. Visual indicators
❍ D. Beep codes
Answer B is correct. A loopbackadapter can be used to test the networkport
built onto a motherboard or onto a separate networkadapter. The loopback
tester usually works with accompanying software to send and receive data
signals to test whether the port is working.
8. Which of the following components ensure that thermally sensitive devices
do not overheat during the normal operation of a personal computer? Select
all correct answers.
❏ A. UPS
❏ B. Heat sink
❏ C. Fans
❏ D. Ribbon cables
❏ E. Ventilation slots
Answers B, C, and E are correct. Heat sinks are used to dissipate heat from
the surface of semiconductor devices such as the CPU. The exhaust fans blow
the hot air away from internal components. Ventilation slots ensure proper
flow of air inside the computer case.
9. During the POST you can hear only a single beep. What does this beep
usually indicate?
❍ A. A problem with on-board memory.
❍ B. A problem with expanded memory.
❍ C. An audio problem.
❍ D. A successful POST.
Answer D is correct. In most motherboards, the BIOS is programmed to
sound a single beep during a POST to indicate that the POST has successfully
completed.
