NEW QUESTION # 264
A user called the help desk to report an issue with a laptop. Recently, the user has been unable to click the buttons on the track pad or press some keys on the keyboard. The technician inspector the laptop but does not find any physical damage caused by the user. Which of the following is the MOST likely cause of the issue?
- A. Failed accelerometer
- B. Distended capacitors
- C. Swollen battery
- D. Damaged digitizer
Answer: C
Explanation:
Explanation
The most likely cause of the issue is that the laptop has a swollen battery, which is a condition where the battery expands due to gas buildup inside the cells. A swollen battery can cause physical damage to the laptop, such as pushing against the track pad or keyboard and preventing them from functioning properly. The technician should inspect the battery and replace it if it is swollen. A damaged digitizer is not the cause of the issue, as the digitizer is a component that converts touch input into digital signals, and it does not affect the track pad or keyboard. Distended capacitors are not the cause either, as capacitors are electronic components that store electric charge, and they do not affect the track pad or keyboard. A failed accelerometer is not the cause as well, as an accelerometer is a sensor that measures acceleration, and it does not affect the track pad or keyboard.

S/MIME (Secure/Multipurpose Internet Mail Extensions) certificates are used to encrypt and digitally sign emails, and are not related to device connectivity. Bluetooth can be used to connect devices together, but it is not necessary for the device to be able to use cloud services.
NEW QUESTION # 272
Which of the following delivers internet over a copper medium?
- A. DSL
- B. WISP
- C. ONT
- D. SDN
Answer: A
Explanation:
Explanation
The correct answer is C. DSL.
DSL stands for Digital Subscriber Line, which is a technology that delivers internet over a copper medium, such as a telephone line. DSL uses different frequencies than voice calls, so it can provide both internet and phone service simultaneously. DSL can offer faster speeds than dial-up, but it depends on the distance from the service provider and the quality of the copper line .
The other options are not technologies that deliver internet over a copper medium. ONT stands for Optical Network Terminal, which is a device that converts optical signals from a fiber optic cable to electrical signals for a copper cable or a wireless router. ONT is used for fiber-to-the-home (FTTH) internet service, which delivers internet over a fiber optic medium. SDN stands for Software Defined Networking, which is a technology that allows network administrators to manage and control network resources and traffic using software applications. SDN is not related to the physical medium of internet delivery, but rather to the logical layer of network configuration and optimization. WISP stands for Wireless Internet Service Provider, which is a company that delivers internet over a wireless medium, such as radio waves or microwaves. WISP can provide internet access to rural or remote areas where wired connections are not available or feasible.

- B. Clean the toner drums and rollers
- C. Change the paper weight setting.
- D. Upgrade the printer firmware.
Answer: B
Explanation:
If a laser printer is producing output with duplicate images (also known as ghost images), it could be due to an issue with the toner drums and rollers. The first step to eliminate the ghost images would be to clean the toner drums and rollers to remove any excess toner that may be causing the issue.
Ghost images are a common issue in laser printers where an image or text from a previous page appears faintly on subsequent pages. The cause of this issue is usually due to toner residue on the drum or rollers, which can be removed by cleaning the toner drums and rollers. Reference: Study Guide Section 4.6 - Printer technologies

A user has noticed high CPU temperatures when gaming. The user would like to lower the CPU temperature, and cost is not an issue. Which of the following should the user do to BEST cool the CPU while keeping noise to a minimum?
- A. Upgrade the thermal paste.
- B. Use a copper heat sink.
- C. Upgrade the CPU fan.
- D. Install liquid cooling.
Answer: D
Explanation:
Liquid cooling is a method of cooling the CPU by circulating a liquid through a closed loop that absorbs heat from the CPU and transfers it to a radiator. Liquid cooling is more effective and quieter than air cooling, which uses a fan and a heat sink. However, liquid cooling is also more expensive and complex to install. Upgrading the thermal paste, using a copper heat sink, or upgrading the CPU fan are ways to improve air cooling, but they will not lower the CPU temperature as much as liquid cooling.

NEW QUESTION # 277
Which of the following cables should be used when connecting a cable modem to a SOHO router?
- A. Ethernet
- B. Fiber
- C. Coaxial
- D. FireWire
Answer: A
Explanation:
Explanation
The correct answer is C. Ethernet.
An Ethernet cable is a type of network cable that is used to connect devices on a local area network (LAN), such as computers, routers, switches, and modems. Ethernet cables have RJ-45 connectors at both ends, which are similar to telephone jacks but larger. Ethernet cables can carry data signals at speeds ranging from 10 Mbps to 10 Gbps, depending on the type and quality of the cable.
A cable modem is a device that connects to a coaxial cable from a cable service provider and provides high-speed internet access. A SOHO router is a small office/home office router that connects to a cable modem or DSL modem and provides network and internet access to multiple devices on a LAN. A SOHO router typically has one WAN port and four LAN ports. The WAN port is used to connect to the cable modem or DSL modem, while the LAN ports are used to connect to computers or other devices on the LAN.
To connect a cable modem to a SOHO router, an Ethernet cable is needed. The Ethernet cable is plugged into the WAN port of the SOHO router and the Ethernet port of the cable modem. This allows the SOHO router to receive an IP address from the cable service provider and share it with the devices on the LAN using network address translation (NAT). The SOHO router also provides firewall and wireless features for the LAN.
The other options are incorrect because they are not suitable for connecting a cable modem to a SOHO router.
FireWire is a type of serial bus that is used to connect devices such as digital cameras, external hard drives, and audio interfaces. FireWire cables have different connectors than Ethernet cables and cannot be used for network communication. Fiber is a type of optical cable that uses light signals to transmit data over long distances. Fiber cables have special connectors that are not compatible with Ethernet ports. Coaxial is a type of copper cable that has a central conductor surrounded by an insulating layer and a braided shield. Coaxial cables are used for cable TV and internet services, but they cannot be directly connected to Ethernet ports without an adapter.

NEW QUESTION # 278
A user built a new PC with parts sourced torn a popular online vendor. The system boots to the OS and basic browsing works, but whenever the user opens a 4K video or starts to play a game, the system Immediately shuts down. Which of the following is the MOST likely cause of this issue?
- A. The CPU heat sink was attached without adequate thermal paste.
- B. The system does not have enough RAM tor 4K video.
- C. The SSD drives do not have enough Pagefile.
- D. The video card was Installed in the wrong PCIe slot.
Answer: A
Explanation:
Thermal paste is a substance that fills in any gaps between a CPU and its heat sink, which is a device that dissipates heat from the CPU. Without adequate thermal paste, the CPU may overheat and cause the system to shut down automatically to prevent damage. This is especially likely when running 4K video or games, which are more demanding and generate more heat. The technician should check if the CPU heat sink was attached properly and apply enough thermal paste to ensure good contact and heat transfer.

NEW QUESTION # 279
Which of the following is an advantage that OLED displays have over LCD displays?
- A. The power contrast results in finer grayscale levels.
- B. The power consumption is lower.
- C. A backlight is utilized.
- D. The color does not degrade over time.
Answer: B
Explanation:
OLED (Organic Light Emitting Diode) displays have lower power consumption than LCD (Liquid Crystal Display) displays because they do not require a backlight to produce light. Each pixel in an OLED display can emit its own light, which also allows for higher contrast and finer grayscale levels. However, OLED displays are more prone to color degradation over time than LCD displays, which use filters to create colors.
