ITE v7.0 – IT Essentials (Version 7.0) – IT Essentials 7.0 Chapter 2 Exam Answers

  1. What is a good safety precaution to take when opening a computer case?

    • Place tape over the case edges that are sharp.
    • Remove the cover (or door) of the computer case before installing or removing parts.
    • Remove the connections to the front panel before extending the case fully open.
    • Ensure that any loose clothing such as a tie or shirt stay in constant contact with the case when handling internal components.

      Computer cases can easily be a hazard to technicians. Before working inside a computer, examine the case edges and put tape over any of the sharp edges to prevent physical harm. A case is opened, but seldom removed when installing or removing parts. Loose clothing should be secured before you work inside a computer.

  2. What does the “A” in P-A-S-S remind a person to do while using a fire extinguisher?

    • Aim the fire extinguisher at the flames.
    • Aim the fire extinguisher at the base of the fire.
    • Activate the fire extinguisher.
    • Adjust the pressure.

      When using the P-A-S-S memory aid with a fire extinguisher, the “A” in P-A-S-S is for aiming at the base of the fire and not at the flames.

  3. How is a power supply commonly attached to a tower case?

    • restraining strap
    • retention bar
    • screws
    • standoffs

      To install a power supply into a PC tower case, open the case, align the power supply with the case holes, and use screws to attach the power supply to the case.

  4. A technician is replacing a power supply. Which two factors should the technician consider when obtaining the replacement part? (Choose two.)

    • type of case
    • input voltage level of 12 or 5 VDC
    • number of internal fans
    • output voltage
    • wattage

      A technician should consider the following when choosing a power supply:Type of motherboard
      Number and type of connectors
      Type of case
      The computer input power level is either 120 or 240 VAC. Output voltages are standard 3.3, 5, and 12 VDC. A power supply normally has one fan and this is not a selectable option on a fan.

  5. A technician is installing additional memory in a computer. How can the technician guarantee that the memory is correctly aligned?

    • The label on the memory module should always face the CPU.
    • A notch in the memory module should be aligned with a notch in the memory slot.
    • The arrows on the memory module should be aligned with the arrows on the motherboard slot.
    • Memory slots are color coded, with one end red and one end blue.
  6. What is used to prevent the motherboard from touching metal portions of the computer case?

    • an I/O shield
    • thermal compound
    • standoffs
    • ZIF sockets

      Screws and standoffs that are non-metallic may be insulators and protect against grounding.

  7. Which statement describes the purpose of an I/O connector plate?

    • It makes the I/O ports of the motherboard available for connection in a variety of computer cases.
    • It plugs into the motherboard and expands the number of available slots for adapter cards.
    • It provides multiple connections for SATA hard drives to connect to the motherboard.
    • It connects the PCIe adapter slots used for video directly to the CPU for faster processing.

      The I/O plate connects to the back of the case and has holes for each of the ports on the motherboard to push through, allowing the motherboard to be used in many different cases regardless of the number of ports on the board or their layout.

  8. What are three important considerations when installing a CPU on a motherboard? (Choose three.)

    • Antistatic precautions are taken.
    • The CPU is correctly aligned and placed in the socket.
    • The CPU contacts are first cleaned with isopropyl alcohol.
    • The CPU heat sink and fan assembly are correctly installed.
    • The CMOS EPROM battery is removed prior to installing the CPU.
    • Maximum insertion force is applied to the load lever so the CPU is locked in place.

      The CPU is sensitive to static discharges. Its pins are very delicate and it works at high temperatures, so precautions must be taken. If the CPU has been used in another machine or if the fan is being replaced, you might need to remove the old thermal compound using isopropyl alcohol (not on the CPU contacts). The battery does not need to be removed from the motherboard during the CPU installation. This would cause the saved BIOS settings to be lost. Minimum force should be needed to lock the CPU load lever into place.

  9. When a new PC is being built, which component has the most influence when selecting the case and power supply?

    • video card
    • sound card
    • RAM module
    • motherboard
    • hard disk type

      The choice of motherboard determines the type of case and power supply. The form factor of a motherboard must match the type of case and power supply. RAM modules, video cards, and sound cards are installed on the motherboard. They must be compatible with the motherboard. A hard disk is attached to the case, but the dimensions of the drive bays are standardized.

  10. Which two factors must be considered when replacing old RAM modules in a PC? (Choose two.)

    • The new RAM must be compatible with BIOS or UEFI.
    • The new RAM must be compatible with the motherboard.
    • The speed of the new RAM must be supported by the chipset.
    • The power supply must provide the voltage that is requred by the new RAM.
    • The new RAM must match the old RAM in terms of capacity and speed.

      When the RAM on a motherboard is being replaced or upgraded, the new RAM module must be compatible with the current motherboard. In addition, the speed of the new RAM must be supported by the chipset.

  11. Refer to the exhibit. In which section of the motherboard would a memory module be installed?
