NEW QUESTION # 379
A user reports that a computer has been randomly shutting down without warning. Which of the following is the most likely cause of the issue?
- A. Corrupted OS
- B. Low system resources
- C. Incompatible memory modules
- D. Overheated CPU
Answer: D
Explanation:
An overheated CPU is the most likely cause of a computer that has been randomly shutting down without warning. A CPU generates heat when it performs calculations, and if the heat is not dissipated properly, it can damage the CPU or cause it to malfunction. A computer that shuts down randomly is a common symptom of an overheated CPU, as the system tries to protect itself from further damage by shutting down or restarting.
The other options are not as likely to cause this issue. A corrupted OS may cause the computer to crash, display errors, or fail to boot, but it does not affect the CPU temperature or the system fan. Incompatible memory modules may cause the computer to beep, display a blue screen, or fail to recognize the installed RAM, but they do not cause the CPU to overheat or the system to shut down randomly. Low system resources may cause the computer to slow down, freeze, or display a low memory warning, but they do not affect the CPU temperature or the system fan.
To troubleshoot and resolve an overheated CPU issue, the user should check and clean the air vents, provide proper ventilation, apply thermal paste, replace the fan or the heat sink, or upgrade the CPU if necessary. The user should also update the BIOS and the device drivers, adjust the power settings, and monitor the system temperature using diagnostic tools.

NEW QUESTION # 381
A user takes a tablet to a technician because the cursor on it keeps drifting. The technician notices the screen does not appear to be damaged. Which of the following is the MOST likely cause of the cursor issue?
- A. The screen is physically damaged.
- B. The touch-pen battery is depleted.
- C. The screen rotation is incorrect.
- D. The screen needs to be recalibrated.
Answer: D
Explanation:
On a laptop, if touchpad sensitivity is too high, typing can cause vibrations that move the cursor.
Examples include the pointer drifting across the screen without any input or a 'ghost cursor' jumping about when typing. Install up-to-date drivers and configure input options to suit the user.
Many laptops now come with a Fn key to disable the touchpad.
If you can rule out simple hardware causes, unresponsive or inaccurate touch input can be an indication of resources being inadequate (too many open apps) or badly written apps that hog memory or other resources. A soft reset will usually fix the problem in the short term.
NEW QUESTION # 382
A customer reports a network connectivity issue. A technician discovers that LAN ports have been damaged during remodeling. Which of the following tools should the technician use to fix the issue?
- A. Punchdown tool
- B. Network tap
- C. Cable stripper
- D. Crimper
Answer: A
Explanation:
The correct answer is B. Punchdown tool.
A punchdown tool is a device that can connect wires to a patch panel or a network jack by inserting them into the appropriate slots and cutting off the excess. A punchdown tool can be used to fix the damaged LAN ports by replacing the wires or reconnecting them to the correct terminals.
A cable stripper is a device that can remove the insulation from a cable to expose the wires inside. A cable stripper is not useful for fixing the damaged LAN ports, unless the technician needs to strip new wires before punching them down.
A crimper is a device that can attach connectors to the ends of cables, such as RJ-45 or RJ-11. A crimper is not useful for fixing the damaged LAN ports, unless the technician needs to replace the connectors on the cables.
A network tap is a device that can monitor and capture network traffic by creating a copy of the data passing through a network link. A network tap is not useful for fixing the damaged LAN ports, as it does not affect the connectivity of the network devices.

NEW QUESTION # 384
Given the following output from a cable tester:
= Open
=12345678=
=12 45 78=
Which of the following tools should the technician use to resolve this issue? (Select two).
- A. Punchdown tool
- B. Loopback plug
- C. Network tap
- D. Toner probe
- E. Wi-Fi analyzer
- F. Crimper
Answer: A,F
Explanation:
The output from the cable tester indicates that there is an open fault in the cable, which means that one or more of the wires in the cable are not connected properly or are broken. The open fault affects the wires 3, 4, and 6, which are used for transmitting and receiving data in Ethernet networks. The open fault can cause network connectivity issues, such as no link, slow speed, or packet loss12.
To resolve this issue, the technician should use a crimper and a punchdown tool, which are tools that are used to attach connectors to cables or wires to patch panels. A crimper is a tool that squeezes or crimps a connector, such as an RJ-45, to the end of a cable, ensuring that the wires are securely inserted into the pins of the connector. A punchdown tool is a tool that pushes or punches a wire into a slot on a patch panel, creating a connection between the wire and the panel. Both tools can be used to fix or replace the faulty wires or connectors that cause the open fault12.
The other options are not as effective or relevant as a crimper and a punchdown tool. A loopback plug is a tool that is used to test the functionality of a network port or device, by sending and receiving signals from the same port or device. A loopback plug can help diagnose network problems, such as faulty ports or devices, but it cannot fix the open fault in the cable12. A network tap is a tool that is used to monitor or capture network traffic, by creating a copy of the data that passes through a network link. A network tap can help analyze network performance, security, or troubleshooting, but it cannot fix the open fault in the cable12. A toner probe is a tool that is used to trace or identify a cable or wire, by sending and detecting an audible tone along the cable or wire. A toner probe can help locate or label network cables or wires, but it cannot fix the open fault in the cable12. A Wi-Fi analyzer is a tool that is used to scan or measure wireless networks, by displaying information such as signal strength, channel, encryption, etc. A Wi-Fi analyzer can help optimize or troubleshoot wireless networks, but it cannot fix the open fault in the cable12.

NEW QUESTION # 394
A laser printer is making humming and grinding noises, and the printouts have ghost images on the pages. Which of the following should be replaced?
- A. Rollers
- B. Paper
- C. Cartridge
- D. Fuser
Answer: D
Explanation:
The most likely answer is C. Fuser.
A fuser is a component in a laser printer that uses heat and pressure to fuse the toner powder onto the paper. If the fuser is damaged or worn out, it can cause humming and grinding noises, as well as ghost images on the printouts. Ghost images are faint copies of previous images that appear on the same page. They are caused by the fuser not heating the toner properly, or by the toner sticking to the fuser roller and transferring to the next page12.
To fix this problem, you should replace the fuser unit with a new one. You can check your printer manual for instructions on how to remove and install the fuser unit. You can also use a diagnostic ruler to measure the distance between the ghost images and determine if the fuser is the source of the problem2. If the ghost images are far apart (between 4cm and 5cm), then the fuser is likely to be faulty.

NEW QUESTION # 395
A technician is troubleshooting a laptop that displays a blank screen when the user turns it on. The technician shines a flashlight into the LCD and sees a faint image. Which of the following is the most likely cause of the issue?
- A. Burned-out bulb
- B. Incompatible video driver
- C. Incorrect input source
- D. Defective inverter
Answer: D
Explanation:
The most likely cause of the issue is a defective inverter. An inverter is a device that converts the direct current (DC) power from the laptop battery or adapter to the alternating current (AC) power that the LCD backlight bulb needs. The backlight bulb is a fluorescent lamp that illuminates the LCD screen and makes the image visible. If the inverter is defective, it may not provide enough power to the backlight bulb, or it may stop working intermittently. This can result in a dim, dark, or blank screen, even though the LCD panel is still functioning and displaying a faint image.
To troubleshoot a defective inverter, the technician can follow these steps:
Connect an external monitor to the laptop and check if the image is displayed normally. If the external monitor works fine, it means that the laptop video card and driver are not the cause of the issue.
Shine a flashlight into the LCD screen and look for a faint image. If the image is visible, it means that the LCD panel is not the cause of the issue.
Check the inverter cable and connector for any damage, loose connection, or corrosion. The inverter cable is a thin wire that runs from the laptop motherboard to the inverter board, which is usually located at the bottom of the LCD screen. The inverter connector is a small plug that connects the inverter cable to the inverter board. The technician can try to reseat the inverter cable and connector, or replace them if they are faulty.
Check the inverter board for any damage, burn marks, or blown fuses. The inverter board is a small circuit board that contains the inverter and other components. The technician can try to test the inverter board with a multimeter, or replace it if it is defective.

- A. The microSD cards were not properly formatted before being installed.
- B. The microSD cards are not compatible with the smartphones.
- C. The microSD cards were not selected for camera storage.
- D. The microSD cards are not capable of UHD storage.
Answer: A
Explanation:
If users are only able to save a small number of pictures on the microSD cards before running out of space, it suggests a formatting issue. Improper or incomplete formatting can lead to the card not utilizing its full storage capacity, resulting in significantly less available space for storing pictures. Formatting the microSD cards correctly would ensure the file system on the cards is set up properly, allowing the devices to use the full capacity of the cards for storage. Compatibility, UHD storage capability, and camera storage settings are less likely to be the issue in this scenario.
