1. Question1 pointsWhat is a good safety precaution to take when opening a computer case?CorrectIncorrect
HintComputer 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. Question1 pointsWhat does the “A” in P-A-S-S remind a person to do while using a fire extinguisher?CorrectIncorrect
HintWhen 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. Question1 pointsHow is a power supply commonly attached to a tower case?CorrectIncorrect
HintTo 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. Question1 pointsA technician is replacing a power supply. Which two factors should the technician consider when obtaining the replacement part? (Choose two.)CorrectIncorrect
HintA technician should consider the following when choosing a power supply:Type of motherboard Wattage 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. Question1 pointsA technician is installing additional memory in a computer. How can the technician guarantee that the memory is correctly aligned?CorrectIncorrect
6. Question1 pointsWhat is used to prevent the motherboard from touching metal portions of the computer case?CorrectIncorrect
HintScrews and standoffs that are non-metallic may be insulators and protect against grounding.
7. Question1 pointsWhich statement describes the purpose of an I/O connector plate?CorrectIncorrect
HintThe 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. Question1 pointsWhat are three important considerations when installing a CPU on a motherboard? (Choose three.)CorrectIncorrect
HintThe 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. Question1 pointsWhen a new PC is being built, which component has the most influence when selecting the case and power supply?CorrectIncorrect
HintThe 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. Question1 pointsWhich two factors must be considered when replacing old RAM modules in a PC? (Choose two.)CorrectIncorrect
HintWhen 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. Question1 pointsRefer to the exhibit. In which section of the motherboard would a memory module be installed?CorrectIncorrect
HintMemory modules insert into memory expansion slots that have a retaining clip at each end of the slot.
12. Question1 pointsWhich type of motherboard expansion slot sends data one bit at a time over a serial bus?CorrectIncorrect
HintA PCIe expansion slot connects to a serial bus that sends data one bit at a time at a much faster rate than the older PCI slot that connects to a parallel bus.
13. Question1 pointsWhich PC motherboard bus is used to connect the CPU to RAM and other motherboard components?CorrectIncorrect
HintThe front-side bus (FSB) is used to connect the CPU to RAM, expansion cards, and other motherboard components. The speed of this bus is relevant when selecting replacement motherboards and RAM.
14. Question1 pointsWhere is buffered memory commonly used?CorrectIncorrect
HintBuffered memory is used in computers that have a lot of RAM such as servers and high-end workstations. Buffered memory should be avoided in gaming, business, and home computers because it slows the memory speed.
15. Question1 pointsA technician has been asked to upgrade a processor and needs to do some research. The computer is just a couple of years old. What are two types of processor packages that could be used inside the computer? (Choose two.)CorrectIncorrect
HintTwo architectures used with CPUs today are the pin grid array (PGA) and the land grid array (LGA). The PGA has pins on the bottom of the processor. The LGA has pins within the socket.
16. Question1 pointsA student is looking to add memory in order to speed up a tower computer. Which type of memory module should the student be looking for?CorrectIncorrect
HintMotherboards in tower computers accept dual inline memory modules (DIMMs) in the memory expansion slots. A motherboard supports a particular type of DIMM such as a DDR3 or DDR4 module.
17. Question1 pointsWhich type of drive is typically installed in a 5.25 inch (13.34 cm) bay?CorrectIncorrect
HintOptical drives are installed in 5.25 inch (13.34 cm) drive bays that are accessed from the front of the case. Flash drives typically connect to USB ports. SSDs and hard drives typically install in a 3.5 inch (8.9 cm) drive bay or a 5.25 inch (13.34 cm) drive bay that is not accessed from the front of the case. If the drive is smaller than the bay, a tray may be purchased.
18. Question1 pointsA technician has been asked to order a replacement internal SATA HDD. Between which two form factors will the technician have to choose? (Choose two.)CorrectIncorrect
HintFor tower computers, internal HDDs are available in the 3.5 and 2.5 inch (8.89 cm and 6.35 cm) form factors. SSDs tend to be the 2.5 inch form factor.
19. Question1 pointsWhile shopping for a replacement motherboard, a customer decides to also purchase a new mechanical hard drive and asks the technical salesperson for advice. Which storage interface should the salesperson recommend for the motherboard and new drive?CorrectIncorrect
HintMechanical hard drives today use SATA. Legacy PATA drives used IDE and EIDE. RAID 5 is a drive redundancy technology.
20. Question1 pointsWhich type of motherboard expansion slot has four types ranging from x1 to x16 with each type having a different length of expansion slot?CorrectIncorrect
HintThe PCIe, or PCI Express, bus has four types of expansion slots with varying lengths: x1, x4, x8, and x16.
21. Question1 pointsA technician is installing a new high-end video adapter card into an expansion slot on a motherboard. What may be needed to operate this video adapter card?CorrectIncorrect
HintWhen a high performance video adapter card is used, multiple power connectors may be required. These connectors may each use a 6-pin or 8-pin power connector. Video adapter cards commonly use the PCIe X 16 slot. A 24-pin ATX power connector is used to provide power to the motherboard.
22. Question1 pointsRefer to the exhibit. Which type of expansion slot is shown?CorrectIncorrect
HintThe four expansion slots shown in the exhibit from left to right are the PCIe x1, PCI, PCIe x16, and PCIx1.
23. Question1 pointsRefer to the exhibit. Which device is shown?CorrectIncorrect
HintA media reader can be an external USB-attached device or an internal device used to read or write to media cards.
24. Question1 pointsWhen assembling a PC, how is pin 1 identified on the front panel cables so that it can be aligned properly with pin 1 on the motherboard panel connector?CorrectIncorrect
HintEach cable that connects to the front panel connector on the motherboard is marked with a small arrow to identify which pin is pin 1 so that it can be aligned with pin 1 on the panel.
