Which action is recommended to prevent the motherboard from contacting the metal base of the case?
- A.
Ensure that the non-conductive side of the case is beneath the motherboard.
- B.
Use standoffs to keep the motherboard above the metal base.
- C.
Place a non-conductive barrier between the motherboard and the metal base.
- D.
Use a self-adhesive non-conductive membrane on the underside of the motherboard.
Correct Answer
B. Use standoffs to keep the motherboard above the metal base.Explanation
To prevent the motherboard from contacting the metal base of the case, it is recommended to use standoffs. Standoffs are small screws or pegs that elevate the motherboard above the metal base, creating a gap between them. This helps to ensure that the motherboard does not come into direct contact with the conductive metal, reducing the risk of short-circuits and damage to the components. Using standoffs is a common practice in computer assembly to provide proper insulation and grounding for the motherboard.Rate this question:

A technician is installing a new CPU in a ZIF socket on a motherboard. What is the primary way of securing the CPU in place?
- A.
Thermal compound
- B.
Antistatic fasteners
- C.
Load lever
- D.
Screws
Correct Answer
C. Load leverExplanation
The load lever is the primary way of securing the CPU in place. It is a mechanism that is used to lock the CPU into the ZIF (Zero Insertion Force) socket on the motherboard. The load lever is lifted to open the socket, allowing the CPU to be inserted easily. Once the CPU is in place, the load lever is lowered, applying pressure to secure the CPU firmly in the socket. This ensures proper contact between the CPU and the socket, allowing for efficient heat transfer and optimal performance.Rate this question:

A technician has just finished assembling a new computer. When the computer is powered up for the first time, the POST discovers a problem. How does the POST indicate the error?
- A.
It issues a number of short beeps.
- B.
The LED on the front of the computer case flashes a number of times.
- C.
It places an error message in the BIOS.
- D.
It locks the keyboard.
Correct Answer
A. It issues a number of short beeps.Explanation
When the computer is powered up for the first time and the POST (Power-On Self-Test) detects a problem, it indicates the error by issuing a number of short beeps.

Which solution should be used to clean a CPU and a heat sink?
- A.
Soap and water
- B.
Rubbing alcohol
- C.
A diluted ammonia solution
- D.
Isopropyl alcohol
Correct Answer
D. Isopropyl alcoholExplanation
Isopropyl alcohol is the correct solution to clean a CPU and a heat sink. This is because isopropyl alcohol is a highly effective solvent that evaporates quickly without leaving any residue. It is commonly used for cleaning electronic components as it can dissolve and remove dirt, dust, and thermal paste without causing damage. Soap and water, rubbing alcohol, and a diluted ammonia solution may not be as effective or may leave residue behind, making isopropyl alcohol the preferred choice for cleaning CPUs and heat sinks.Rate this question:

After a technician has assembled a new computer, it is necessary to configure the BIOS. At which point must a key be pressed to start the BIOS setup program?
- A.
Before the computer is powered on
- B.
During the Windows load process
- C.
During the POST
- D.
After the POST, but before Windows starts to load
Correct Answer
C. During the POSTExplanation
During the POST (Power-On Self Test) is the point at which a key must be pressed to start the BIOS setup program. The POST is a series of diagnostic tests that the computer performs to ensure that all hardware components are functioning properly. By pressing a specific key during this process, the user can access the BIOS setup program, which allows them to configure various settings for the computer's hardware and software. Pressing the key before or after the POST would not initiate the BIOS setup program.Rate this question:
