Question #150
A network technician needs to provide better wireless connectivity throughout a SOHO location.
Which of the following should the technician deploy to best improve connectivity?
- A . Access point
- B . Managed switch
- C . POE hub
- D . Wi-Fi router
Correct Answer: A
A
Explanation:
The correct answer is A) Access point.
An access point is a device that extends the wireless coverage of a network by creating a hotspot that allows wireless devices to connect to the network1. An access point can be connected to a router or a switch via an Ethernet cable or a wireless bridge1. By deploying one or more access points throughout a SOHO location, the technician can provide better wireless connectivity and eliminate dead zones or weak signals2.
A managed switch is a device that allows multiple devices to communicate on a network by forwarding data packets based on their destination addresses3. A managed switch can also provide advanced features such as VLANs, QoS, security, and remote management3. However, a managed switch does not improve wireless connectivity, as it only works with wired devices.
A POE hub is a device that provides power and data over a single Ethernet cable to devices that support Power over Ethernet (PoE) technology, such as IP cameras, VoIP phones, and wireless access points4. A POE hub can simplify the installation and placement of these devices by eliminating the need for separate power adapters or outlets4. However, a POE hub does not improve wireless connectivity by itself, as it still requires an access point or a router to create a wireless network.
A Wi-Fi router is a device that combines the functions of a router and an access point, providing both wired and wireless connectivity to a network and the internet. A Wi-Fi router can be used to create a SOHO network, but it may not be sufficient to cover the entire location with a strong and reliable wireless signal. To improve wireless connectivity, the technician may need to add additional access points or use a mesh Wi-Fi system that consists of multiple routers that work together to create a seamless wireless network.
Therefore, an access point is the best option among the choices to improve wireless connectivity throughout a SOHO location.

Question #158
A user reports that when pressing a radio button on a tablet, an item a couple of inches to the right of the pressed button gets selected instead.
Which of the following components may need to be replaced?
- A . Gyroscope
- B . Battery
- C . Digitizer
- D . Glass
Correct Answer: C
C
Explanation:
A digitizer is a component that converts the touch input on a tablet screen into digital signals that can be processed by the device. A digitizer consists of a thin layer of transparent material that covers the glass screen and has sensors that detect the position and pressure of the touch. If the digitizer is damaged, misaligned, or poorly calibrated, it can cause inaccurate touch input, such as selecting the wrong item or not responding at all12. Therefore, the most likely cause of the issue in this scenario is a faulty digitizer that may need to be replaced. The other components are not directly related to the touch input functionality of the tablet. A gyroscope is a sensor that measures the orientation and rotation of the device3. A battery is a power source that supplies electricity to the device4. A glass is a protective layer that covers the screen and prevents scratches and cracks5.

Question #159
A technician is replacing the motherboard of a workstation for a user who runs multiple large applications at the same time.
Which of the following
motherboard specifications would provide the most significant improvement in performance?
- A . Number of DIMM slots
- B . Number of HDMI ports
- C . Number of PCI slots
- D . Number of USB ports
Correct Answer: A
A
Explanation:
The correct answer is A. Number of DIMM slots.
The number of DIMM slots on a motherboard determines how much RAM can be installed on the system. RAM is a crucial component for running multiple large applications at the same time, as it allows the CPU to access data faster and avoid swapping to the hard drive. Having more DIMM slots means that more RAM can be added, which can improve the performance and responsiveness of the system.
B) Number of HDMI ports. This is not a correct answer. The number of HDMI ports on a motherboard determines how many monitors can be connected to the system. HDMI ports are used for video and audio output, but they do not affect the performance of the system when running multiple large applications.
C) Number of PCI slots. This is not a correct answer. The number of PCI slots on a motherboard determines how many expansion cards can be installed on the system. PCI slots are used for adding devices such as sound cards, network cards, or graphics cards, but they do not affect the performance of the system when running multiple large applications.
D) Number of USB ports. This is not a correct answer. The number of USB ports on a motherboard determines how many peripherals can be connected to the system. USB ports are used for connecting devices such as keyboards, mice, printers, or external drives, but they do not affect the performance of the system when running multiple large applications.

Question #160
A small company wants the ability to print in full color but needs to pay a minimal initial purchase price for the printer.
Which of the following is the best option?
- A . Thermal printer
- B . Inkjet printer
- C . Dot matrix printer
- D . Laser printer
Correct Answer: B
B
Explanation:
Inkjet printers are the best choice for a small company seeking full-color printing with a minimal initial cost. While they have higher operating costs (due to ink), they are affordable and capable of high-quality color output.
Why Not A (Thermal printer): Thermal printers are not designed for color printing and are typically used for labels or receipts.
Why Not C (Dot matrix printer): Dot matrix printers are outdated, noisy, and do not support full-color printing.
Why Not D (Laser printer): Laser printers have lower running costs but a higher initial purchase price, especially for color models.
