For the second ordered part (the Gigawhiz GA-A239VM, which does not include USB 3.1 front panel connectors), which installation step will be applicable for the technician?

Attach the device to the case and secure the screws so the internal fan does not vibrate.
Align the item with the standoffs in the case.*
Secure the latch plate by closing the load lever.
Align the notches on the module to the keys in the slot and firmly press straight down.

Explanation:
A Gigawhiz GA-A239VM is a type of motherboard since it mentions front panel connectors. The system panel connector is used to attach cables between the motherboard and the front of the case for USB ports, power button, microphone jack, headphones jack, etc. Standoffs keep the motherboard from grounding to the case. The holes in the motherboard should align to the standoffs. Each standoff screws into the case. Then screws are used to securely attach the motherboard to the case (via the standoffs).

Which part should be tightly screwed into the case so that fan vibrations do not loosen it?

part 3
part 5
part 1
part 6*

Explanation:
Part 6 is a power supply. Power supplies have fans that provide proper air flow through the interior of the computer case. Power supplies should be tightly screwed to the case (but not over tightened) so that the fan vibrations do not loosen it.

After building the computer, the technician powers on the computer. The system beeps several times. Which component caused the beeps and where is this component located? (Choose two.)

CMOS
Motherboard*
Event Viewer
hard drive
BIOS*
timer

Explanation:
The BIOS contains a power on self test (POST) program that tests hardware during computer startup. One beep is a common indication that all is well. Several beeps indicate a hardware issue. BIOS is built into the motherboard, so it is the motherboard documentation that should be consulted to resolve this issue.

6. What should be done prior to the installation of RAM onto the motherboard?

Ensure the memory expansion slot tabs are in the locked position before inserting the RAM module.
Consult the motherboard documentation or website of the manufacturer to ensure that the RAM is compatible with the motherboard.*
Change the voltage selector to meet with the voltage specification of the RAM.
Populate the center memory slots first before inserting the new RAM.

Explanation:
Before you install a memory module it is important to verify that there are no compatibility issues. A DDR3 RAM module will not fit in a DDR2 slot. Verification is best done by consulting the motherboard documentation or checking on the website of the manufacturer.

7. A motherboard has a 24-pin socket for the main power connector. Which ATX power supply connector will work?

12-pin connector
20-pin connector*
18-pin connector
16-pin connector

Explanation:
The Advanced Technology Extended (ATX) main power connector will have either 20 or 24 pins. The power supply may also have a 4-pin or 6-pin Auxiliary (AUX) power connector that connects to the motherboard. A 20-pin connector will work in a motherboard with a 24-pin socket.

8. Where is the saved BIOS configuration data stored?

CMOS*
RAM
hard drive
cache

Explanation:
The BIOS configuration data is saved to a special memory chip called a Complementary Metal Oxide Semiconductor (CMOS).

9. Which website should a technician consult to find instructions for updating the BIOS on a computer?

case manufacturer
motherboard manufacturer*
operating system developer
CPU manufacturer

Explanation:
Go to the motherboard manufacturer site to get the correct software to update the BIOS.

10. Which procedure is performed last when installing a new motherboard?

Install the I/O shield.
Connect the peripheral devices.*
Secure the expansion cards.
Tighten the motherboard screws.

Explanation:
After the new motherboard is in place and cables are connected, you should install and secure all expansion cards. Finally, connect the keyboard, mouse, and monitor, then power on the computer to check for problems.

11. What indicates that the charge on the CMOS battery could be getting low?

A beep error code occurs during POST.
The computer time and date are incorrect.*
Performance while accessing files on the hard drive is slow.
The computer fails to boot.

Explanation:
The computer time and date are held in CMOS. This requires power from a small battery. If the battery is getting low, the system time and date may become incorrect.

12. What are two examples of settings that can be changed in the BIOS setup program? (Choose two.)

drive partition size
device drivers
swap file size
boot order*
enabling and disabling devices*

Explanation:
The BIOS setup program is used to change settings if memory modules, storage devices, and adaptor cards are added. Most manufacturers provide the ability to modify boot device options, security and power settings, and adjustments for voltage and clock settings.

13. Which definition describes the term “overclocking”?

increasing the speed of the CPU beyond the recommendations of the manufacturer*
replacing slower SDRAM with faster memory
modifying the motherboard clocking crystal to increase the timing signals
changing the bus speed of the motherboard to increase the speed of attached adaptors

Explanation:
Increasing the CPU clock speed will make the computer run faster, but also generate more heat and cause overheating issues.

14. What should be used to clean the base of the CPU heat sink prior to reinstallation?

water
isopropyl alcohol*
thermal compound
rubbing alcohol

Explanation:
When reinstalling the heat sink, clean the base of the heat sink with isopropyl alcohol. This removes all traces of old thermal compound so the newly applied thermal compound works properly.

15. When mounting a motherboard in a computer case, what is used to prevent the motherboard from touching the bottom of the case?

grounding straps
standoffs*
silicon spray
ground-fault isolators

16. What is an advantage of using signed drivers?

They are free of errors.
They never need upgrading.
They are guaranteed to work with all operating systems.
They are guaranteed by the manufacturer to work with any hardware.
They are verified to be compatible with the operating system.*

Explanation:
A signed driver is a driver that has passed the Windows hardware quality lab test and has been given a driver signature by Microsoft. Installing an unsigned driver can cause system instability, error messages, and boot problems.
