• Question 552:

  Which of the following display types is available for laptops?

  A. OLED
  B. CRT
  C. DLP
  D. Plasma
  A. OLED

  ---

  Explanation

  OLED stands for Organic Light-emitting Diode, and it is one of the three display types available for laptops, along with TN (Twisted Nematic) and IPS (In-Plane Switching) panels1. OLED displays use organic compounds that emit light when an electric current is applied, unlike LCD displays that use a backlight to illuminate the pixels. OLED displays have several advantages over LCD displays, such as higher contrast, wider viewing angles, faster response times, and lower power consumption2. However, OLED displays are also more expensive, less common, and more prone to burn-in than LCD displays2. CRT (Cathode Ray Tube), DLP (Digital Light Processing), and Plasma are not display types for laptops. CRT is an old technology that uses a vacuum tube to project an image on a phosphor screen. CRT monitors are bulky, heavy, and consume a lot of power3. DLP is a technology that uses a digital micromirror device and a light source to project an image on a screen or a wall. DLP is mainly used for projectors, not laptops4. Plasma is a technology that uses gas-filled cells that emit light when an electric current is applied. Plasma displays are mainly used for large-screen TVs, not laptops.

• Question 553:

  A technician is tasked with upgrading a laptop's RAM. Which of the following steps should the technician lake FIRST?

  A. Confirm that both the current and new memory are from the same brand.
  B. Run a diagnostic test on the current memory.
  C. Verify the memory requirements of the motherboard.
  D. Connect an electrostatic discharge strap.
  C. Verify the memory requirements of the motherboard.

  ---

  Explanation

  If a technician is tasked with upgrading a laptop's RAM, the technician should verify the memory requirements of the motherboard first. The motherboard of the laptop will have specific requirements for the type and amount of RAM that can be installed. By verifying the memory requirements of the motherboard, the technician can ensure that the new RAM is compatible with the laptop. Before upgrading a laptop's RAM, a technician should verify the memory requirements of the motherboard to ensure the new RAM is compatible. The type, speed, and maximum capacity of the RAM should be checked to ensure it meets the requirements of the motherboard.

• Question 554:

  An administrator chose a shared-tenant model for a cloud deployment. Which of the following is the MOST likely reason the administrator chose this model?

  A. Cost savings
  B. Highly available
  C. Dedicated hardware
  D. Increased security
  A. Cost savings

  ---

  Explanation

  The shared-tenant model for a cloud deployment, also known as a multi- tenant model, allows multiple customers to use the same resources and infrastructure of the cloud service provider, with each customer's data and applications isolated from one another. This model is often chosen for cost savings, as resources are shared and users only pay for what they use. Therefore, the MOST likely reason that an administrator chose this model is A. Cost savings.

• Question 555:

  A technician is troubleshooting issues occurring on a user's mobile device. Applications and the OS have slow response times, even when performing simple tasks, such as writing an email. Additionally, new applications occasionally fail to launch. Which of the following should the technician do next?

  A. Move the device to a room with a colder temperature.
  B. Close unnecessary programs.
  C. Reset to factory default settings.
  D. Check the battery health of the device.
  B. Close unnecessary programs.

  Explanation

• Question 556:

  A technician is upgrading the memory on a server that processes payment information online. Which of the following types of memory would the technician most likely install?

  A. DDR4
  B. VRAM
  C. SODIMM
  D. ECC
  D. ECC

  ---

  Explanation

  ECC stands for Error Correction Code, which is a type of memory that can detect and correct data errors that may occur during processing or transmission. ECC memory is commonly used in servers that handle sensitive or critical information, such as payment information online, because it can reduce the risk of data corruption, system crashes, or security breaches12. DDR4 is a generation of DDR technology, which stands for Double Data Rate. DDR4 memory is faster and more power-efficient than its predecessors, but it does not necessarily have ECC functionality. DDR4 memory can be either ECC or non-ECC1. VRAM is Video RAM, which is a type of memory that is dedicated to storing graphics data for display. VRAM is usually found on graphics cards or integrated graphics processors, not on servers3. SODIMM is Small Outline DIMM, which is a type of memory module that has a smaller size and lower profile than regular DIMMs. SODIMMs are typically used in laptops, notebooks, or other compact devices, not on servers3.

• Question 557:

  Atechnician is replacing all RJ45 cables in a customer environment. Which of the following are the BEST tools to execute the task? (Select TWO).

  A. Optical fiber tester
  B. Scissors
  C. Cable tester
  D. Crimper
  E. Coaxial cable
  F. Screwdriver
  C. Cable tester
  D. Crimper

  ---

  Explanation

  A cable tester and a crimper are the best tools to execute the task of replacing all RJ45 cables in a customer environment. A cable tester can be used to check the continuity and quality of a cable, and a crimper can be used to attach RJ45 connectors to the ends of a cable. An optical fiber tester is a tool that can be used to test fiber optic cables, which are not RJ45 cables. Scissors are not a tool for replacing cables, but for cutting them. A coaxial cable is a type of cable that has a single copper conductor at its center, which is not an RJ45 cable either. A screwdriver is not a tool for replacing cables, but for fastening or loosening screws.

• Question 558:

  A user is having an issue with the touch screen on a mobile device. When the user touches the screen, the intended target is not selected. Which of the following would be the BEST action for a technician to take to resolve the issue?

  A. Calibrate the touch screen.
  B. Reset the mobile device.
  C. Replace the LED screen.
  D. Update the mobile device.
  A. Calibrate the touch screen.

  ---

  Explanation

  Calibrating the touch screen is the best action to resolve the issue of inaccurate touch input. Calibration adjusts the touch screen's sensitivity and alignment to match the user's touch. Resetting the mobile device could erase user data and settings and may not fix the touch screen issue. Replacing the LED screen or updating the mobile device are unnecessary and costly actions that may not solve the problem.

• Question 560:

  A technician has noticed that a monitored server is receiving a disk failure notice during startup. When the technician clicks to continue, the machine still seems to startup into Windows but at a much slower speed. The technician looks at the BIOS information and sees the machine utilizes a RAID 5 configuration. Which of the following does the technician MOST likely need to perform?

  A. Reinstall the HDD drivers.
  B. Rebuild The RAID.
  C. Replace the failed drivers.
  D. Restart the system.
  B. Rebuild The RAID.

  ---

  Explanation

  The disk failure notice during startup indicates that one or more disks in the RAID array have failed. The machine still seems to startup into Windows but at a much slower speed because the RAID 5 configuration can tolerate one disk failure and still operate, but with reduced performance and reliability. The technician most likely needs to rebuild the RAID, which means replacing the failed disk(s) and restoring the data from the parity information. Reinstalling the HDD drivers will not fix the disk failure. Replacing the failed drivers is not a valid option, as drivers are software, not hardware. Restarting the system will not fix the disk failure either.
