    A technician finds the inside of a desktop computer completely covered in almost 1 inch (2.54 centimeters) of dust. Which of the following would be the BESTsolution to clean out the inside of the case?

    • Compressed Air

    • Wet Cloth

    • Dry Rag

    • Lint Free Cloth

    Correct Answer
    A. Compressed Air
    Explanation
    Compressed air would be the best solution to clean out the inside of the case because it can effectively remove dust from hard-to-reach areas without causing any damage to the components. A wet cloth or dry rag may not be able to reach all the nooks and crannies inside the case, and using them could also introduce moisture or static electricity, which can harm the delicate electronic parts. A lint-free cloth may be useful for wiping down the exterior of the case, but it may not be sufficient for removing the thick layer of dust inside.

    Which of the following properties of a heat sink has the GREATEST affect on heat dispersion?

    • Surface area

    • Connection

    • Shape

    • Location

    Correct Answer
    A. Surface area
    Explanation
    Surface area has the greatest effect on heat dispersion in a heat sink. A larger surface area allows for more contact between the heat sink and the surrounding air, facilitating better heat transfer. This increased surface area allows for more efficient cooling, as more heat can be dissipated into the environment. Therefore, the greater the surface area of a heat sink, the more effective it will be at dispersing heat.

    Which of the following should be used when cleaning toner inside a laser printer?

    • Rubber gloves

    • Static Wrist Band

    • Wet Cloth

    • Eyewear

    Correct Answer
    A. Rubber gloves
    Explanation
    Rubber gloves should be used when cleaning toner inside a laser printer to protect the hands from coming into direct contact with the toner. Toner can be harmful if it gets on the skin or is inhaled. Rubber gloves provide a barrier between the toner and the skin, preventing any potential harm. Using rubber gloves also helps to maintain cleanliness and prevent any smudges or fingerprints on the printer components.

    • Toggle the function key for the display in the laptop keyboard.

    • Check the power cable to the projector.

    • Put a new bulb in the projector.

    • Replace the video cable to the projector.

    Correct Answer
    A. Toggle the function key for the display in the laptop keyboard.
    Explanation
    The technician should try toggling the function key for the display in the laptop keyboard first. This is because the function key is responsible for switching between different display modes on a laptop, such as extending the display to an external monitor or projector. By toggling the function key, the technician can ensure that the laptop is set to display the screen on the projector. Checking the power cable, replacing the bulb, or replacing the video cable would be secondary troubleshooting steps if toggling the function key does not solve the issue.

    Which of the following is the MAXIMUM number of primary partitions that can exist on a physical hard drive?

    • 4

    • 5

    • 2

    • 3

    Correct Answer
    A. 4
    Explanation
    The maximum number of primary partitions that can exist on a physical hard drive is 4. This is because the Master Boot Record (MBR) partitioning scheme, which is commonly used on most PC systems, allows for a maximum of 4 primary partitions. If more partitions are needed, an extended partition can be created within one of the primary partitions, which can then be divided into logical partitions to create additional storage areas. However, when considering only primary partitions, the maximum is 4.
