You are assembling a new computer and are looking at new cooling systems. Which of the following cooling systems requires the use of a pump? A: Liquid B: Thermal paste C: Heat sink D: Heat sink plus fan

A: Liquid

Which computer component contains all the circuitry necessary for other components or devices to communicate with one another? A: Motherboard B: CPU C: RAM D: Expansion Bus

A: Motherboard

Your Core i5 fan has a four-pin connector, but your motherboard only has a single three-pin header with the CPU_FAN label. Which of the following will be the easiest solution to get the necessary cooling for your CPU? A: Plug the four-pin connector into the three-pin header B: Buy a four-pin to three-pin adapter C: Leave the plug disconnected and use only the heat sink D: Add an extra chassis fan

A: Plug the four-pin connector into the three-pin header

You are training new technicians to install RAM and pointing out the differences between packages. Which of the following are the numbers of pins that can be found on DIMM modules used in desktop motherboards? (Choose two). A: 180 B: 184 C: 200 D: 204 E: 232 F: 240

You need to replace memory in a desktop PC and to go purchase RAM. When you are at the store, you need to find the appropriate type of memory. What memory chips would you find on a stick of PC3-16000? A: DDR-2000 B: DDR3-2000 C: DDR3-1600 D: PC3-2000

B: DDR3-2000, Remember 8:1 rule, the initials PC are used to describe the module; the initials DDR are used for the chips; a single-digit number after PC and DDR is used to represent the level of DDR. The lack of a single-digit number represents DDR as long as that number is greater then 133. This means PC3-1600 modules are DDR3 and populated with DDR3 chips.

A technician asks you how to get a computer's processor to run faster than it currently does. What is he trying to achieve? A: Hyperthreading B: Overclocking C: Virtualization D: Multicore support

B: Overclocking

You need to install a new video card into a desktop computer. What type of expansion slot is preferred today for high-performance graphics adapters? A: AGP B: PCIe C: PCI D: SATA

B: PCIe

You press the front power button on a computer and the system boots. Later, you press it briefly and the system hibernates. When you press it again, the system resumes. You press and hold the button and the system shuts down. What is this feature called? A: Programmable Power B: Soft power C: Relay Power D: Hot Power

B: Soft Power

You have just replaced a processor in a computer and now need to add a cooling mechanism. What should you use to attach the cooling system to the processor? A: Heat sink B: Thermal Paste C: Fan D: Superglue

B: Thermal Paste

You have just found out that a new BIOS upgrade exists for your computer, and you obtain a copy to install it. Which of the following is most helpful when flashing the BIOS on a desktop computer system? A: DVD-ROM B: Uninterruptable Power Supply C: Internet Connection D: Windows Administrator Password

B: Uninterruptable Power Supply

You are replacing a motherboard in a computer that uses an AMD Ryzen 3 processor. Which CPU socket type do you need to ensure that the motherboard has? A: AM2 B: AM3 C: AM4 D: LGA 1151
