• Question 434:

  A regularly used laser printer is printing vertical lines on each page_ Which of the following should the technician do first?

  A. Lower the printing contrast.
  B. Change the paper type
  C. Install a new fuser.
  D. Replace the toner cartridge
  D. Replace the toner cartridge

  ---

  Explanation

  The answer is

  D. Replace the toner cartridge.

  Vertical lines on a laser printer output are usually caused by a faulty or empty toner cartridge, a dirty or damaged drum unit, or a clogged or obstructed laser glass. According to the web search results, some possible steps to troubleshoot and

  resolve this issue are:

  Check the toner level and replace the toner cartridge if it is low or empty1. Remove the toner cartridge and inspect the drum unit for any signs of damage, such as scratches, cracks, or toner buildup. Clean the drum unit with a soft cloth or

  replace it if it is damaged23. Locate the laser glass, which is a narrow strip of glass under the scanner lid or inside the printer. Clean the laser glass with a lint-free cloth moistened with water and remove any dust, dirt, or debris that might block the laser beam24.

• Question 435:

  A customer's laptop is making clicking sounds in the area where non-volatile storage is installed. A technician examines the laptop and confirms the issue. Which of the following is the most appropriate replacement part?

  A. 7,200rpm HDD
  B. NVMe SSD
  C. M.2 SATA SSD
  D. SCSI 15,000rpm HDD
  B. NVMe SSD

  ---

  Explanation

  NVMe stands for Non-Volatile Memory Express, and it is a type of SSD (solid state drive) that uses PCIe (Peripheral Component Interconnect Express) interface to connect to a computer. NVMe SSDs offer faster performance and lower latency than other types of SSDs, such as SATA (Serial ATA) or M.2 SATA. If a user reports that a PC occasionally fails to boot and makes clicking sounds in the area where non-volatile storage is installed, it indicates that the hard drive is failing and needs to be replaced with an NVMe SSD.

• Question 436:

  A user's smartphone battery capacity has started going from full to empty within an hour. The user has not recently installed any new applications on the smartphone. An IT technician notices that the smartphone has very high network utilization and thinks this issue might be related to the battery drain. Which of the following troubleshooting steps should the technician attempt next?

  A. Disable Bluetooth.
  B. Connect the smartphone to a Wi-Fi network.
  C. Restart the smartphone.
  D. Update the mobile OS.
  D. Update the mobile OS.

  ---

  Explanation

  Software updates often include bug fixes and optimizations that can improve battery life and address performance issues. By updating the mobile operating system, the technician can potentially resolve any software-related issues contributing to the excessive battery drain. Additionally, updating the OS ensures that the device has the latest security patches and improvements, enhancing overall device performance and stability.

• Question 437:

  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. Incompatible memory modules
  C. Overheated CPU
  D. Low system resources
  C. Overheated CPU

  ---

  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.
