Question 1

You are troubleshooting a laptop with multiple sticking keys that result in misspelled words while the user types. Other than several sticking keys, the laptop appears to be functioning properly. You have cleaned the keyboard with compressed air, but the problem persists. After removing one of the key tops, it becomes apparent that a liquid was spilled into the keyboard.
Which of the following is the next step in resolving the issue of sticking keys?

A) Replace the keyboard with a compatible keyboard.
B) Disconnect and reseat the keyboard ribbon cable.
C) Clean the keyboard keys with a contact cleaner.
D) Replace the laptop system board and reseat all connections.

Question 2

What tool can help discover and report computer errors and conflicts that occur when you first turn on a computer and before the operating system is launched.&#10;A) POST card&#10;B) OS diagnostic programs&#10;C) Power supply tester&#10;D) Service manual

Accepted Answer

A POST card is used to help diagnose computer errors and conflicts that occur during the Power-On Self-Test, which is the initial set of diagnostic tests performed by the computer right after it is turned on, before the operating system loads.

Question 3

What two devices in a computer should be considered &#34;black boxes,&#34; and should never be opened due to risks involving charged capacitors?&#10;A) Monitor&#10;B) Power supply&#10;C) Hard drive&#10;D) Video card

Accepted Answer

Monitors and power supplies contain capacitors that can retain a charge even when the device is unplugged, posing a risk of electric shock. Hard drives and video cards do not have this risk and can be opened for repairs or upgrades, although opening a hard drive outside of a clean room environment can damage it.

Question 4

How many pins are used in a serial port?&#10;A) 15&#10;B) 9&#10;C) 6&#10;D) 25

Accepted Answer

Serial ports typically use 9 pins in a DB9 configuration.

Question 5

What is the component called that usually has a dual-voltage selector switch and has cables that connect to the motherboard and internal components?&#10;A) PCIe&#10;B) HDD&#10;C) DIMM&#10;D) PSU

Accepted Answer

The PSU (Power Supply Unit) is the component that typically has a dual-voltage selector switch and provides power to the motherboard and other internal components through its cables.

Question 6

Which statement is NOT true regarding motherboards?&#10;A) Has a CPU socket&#10;B) Has slots for DIMMs&#10;C) Has a heat sink on the PCIe slots&#10;D) Also called a system board

Accepted Answer

Motherboards typically do not have heat sinks on the PCIe slots; heat sinks are more commonly found on the CPU, chipset, or sometimes on high-end graphics cards that use PCIe slots.

Question 7

What two different types of firmware may be used on motherboards?&#10;A) BIOS&#10;B) CEFI&#10;C) UEFI&#10;D) CMOS

Accepted Answer

BIOS (Basic Input/Output System) and UEFI (Unified Extensible Firmware Interface) are two types of firmware used on motherboards. BIOS is the older, traditional firmware interface for PCs, while UEFI is the newer specification designed to replace BIOS, offering more features and better security.

Question 8

What is the second step in opening the case of a working computer?&#10;A) Press and hold down the power button for a moment&#10;B) Back up important data&#10;C) Power down the system and unplug it&#10;D) Open the case cover

Accepted Answer

Powering down the system and unplugging it is essential for safety and to prevent damage to the computer or injury to oneself before opening the case.

Question 9

A user called to inform you that the laptop she purchased yesterday is malfunctioning and will not connect to her wireless network. You personally checked to verify that the wireless worked properly before the user left your office. The user states she rebooted the computer several times but the problem still persists.
Which of the following is the first step you should take to assist the user in resolving this issue?

A) Inform the user she will need to return the laptop so you can replace the internal Wi-Fi card and verify wireless functionality.
B) Have the user press the appropriate function key combination to enable the wireless radio and then attempt to connect to the wireless network.
C) Instruct the user on how to reseat the internal mini-PCIe wireless adapter and try to connect to the wireless network.
D) Ask the user to turn on the laptop's airplane mode and attempt to reconnect to the wireless network.

Accepted Answer

The first step should be to ensure the wireless radio is enabled, often done through a function key combination, as it's a common and simple issue that can prevent connection to wireless networks.

Question 10

Which statement is NOT a good practice when working inside a computer case?&#10;A) Don't touch the inside of a computer that is turned on.&#10;B) Don't touch a microchip with a magnetized screwdriver.&#10;C) Remove loose jewelry.&#10;D) Be sure to hold expansion cards by the edge connectors.

Accepted Answer

Holding expansion cards by the edge connectors can damage the connectors and impair the card's functionality. It's better to hold them by the edges of the card itself to avoid static damage and physical harm to the connectors.
