• Question 981:

  A technician responds to a user who has reported that a laptop is too hot. The technician notices the laptop is not able to sit level on the workspace. What of the following BEST describes the issue with the laptop?

  A. The docking station is improperly installed.
  B. The hard drive is disconnected.
  C. The CPU fan is too powerful.
  D. The battery is damaged.
  D. The battery is damaged.

  ---

  Explanation

  A damaged battery can cause a laptop to overheat and swell, making it unable to sit level on the workspace. A swollen battery can also pose a fire hazard and damage other components of the laptop, such as the motherboard or keyboard. The technician should replace the battery as soon as possible and dispose of it properly according to local regulations.

• Question 983:

  Multiple users contact the help desk to report issues with the network fileshares. Files are accessible, but performance is very slow. Which of the following should a technician perform first?

  A. Defragment the files on the network share.
  B. Ask the users to perform a network speed test.
  C. Check the RAID drive status LEDs.
  D. Start the process of rebuilding the array.
  C. Check the RAID drive status LEDs.

  ---

  Explanation

  The correct answer is

  C. Check the RAID drive status LEDs.

  RAID stands for Redundant Array of Independent Disks, which is a technology that combines multiple physical disks into a logical unit that provides improved performance, reliability, or both1. RAID can be implemented using hardware or software, and there are different levels of RAID that use different methods of data distribution and redundancy1. One of the common issues with RAID is disk failure, which means that one or more of the disks in the array stop working properly. Disk failure can affect the performance and availability of the network fileshares, depending on the RAID level and the number of failed disks2. For example, RAID 0, which uses striping to split data across multiple disks, has no redundancy and will lose all data if any disk fails. RAID 1, which uses mirroring to duplicate data on two disks, can tolerate one disk failure and still function. RAID 5, which uses striping with parity to distribute data and error correction information across three or more disks, can also tolerate one disk failure and still function1. One of the ways to detect disk failure is to check the RAID drive status LEDs, which are lights that indicate the health and activity of each disk in the array. Different RAID controllers may have different LED patterns and colors, but generally, a green LED means that the disk is working normally, a red LED means that the disk has failed or is offline, an amber LED means that the disk is degraded or rebuilding, and a blinking LED means that the disk is active or busy34. The first step that a technician should perform when troubleshooting network fileshare issues is to check the RAID drive status LEDs to see if any disk has failed or is degraded. This can help identify the cause of the problem and determine the appropriate solution. For example, if a disk has failed in a RAID 1 or RAID 5 array, the technician can replace the failed disk and rebuild the array to restore performance and redundancy. If a disk has failed in a RAID 0 array, the technician will need to restore the data from a backup2. The other options are not the best steps to perform first. Defragmenting the files on the network share may improve performance by reducing fragmentation, but it will not solve the problem if there is a disk failure in the RAID array. Asking the users to perform a network speed test may help diagnose network issues, but it will not help identify disk issues in the RAID array. Starting the process of rebuilding the array may be necessary after replacing a failed disk, but it should not be done before checking the RAID drive status LEDs.

• Question 984:

  A user connects a laptop to a docking station but is unable to see an image on the external monitor. The user tests the docking station USB ports, and they are working fine. Which of the following should be done NEXT?

  A. Check for firmware updates
  B. Configure extended display mode
  C. Replace the external monitor
  D. Adjust the laptop's BIOS settings
  B. Configure extended display mode

• Question 985:

  A technician is troubleshooting a point-of-sale primer that Is printing blank receipts. Which o( the following should the technician do to resolve the Issue?

  A. Verify the correct type of paper is loaded.
  B. Install the latest print driver.
  C. Check to see if the default printer has been changed.
  D. Ensure the printer is connected to power.
  A. Verify the correct type of paper is loaded.

  ---

  Explanation

  Verifying the correct type of paper is loaded is the best solution for resolving the issue of blank receipts being printed by a point-of-sale printer. Some receipt printers require a specific type of paper, and using the wrong type can result in blank receipts.

  References: https://www.techwalla.com/articles/what-are-the-causes-of-blank-receipts- from-a-printer

  Top of Form Verify the correct type of paper is loaded. If a point-of-sale printer is printing blank receipts, one possible cause could be that the wrong type of paper is loaded in the printer. Thermal printers require thermal paper to print properly. If regular paper is loaded instead of thermal paper, the printer will not be able to produce an image on the paper and will print blank receipts.

• Question 986:

  An IT manager is evaluating ticket resolution times. While reviewing the data, the manager notices repetitive issues are taking longer than expected to resolve. Which of the following changes should the manager implement to resolve repetitive issues more quickly?

  A. Require the technicians to spend more time testing theories to determine the root causes of issues.
  B. Require the technicians to verify full system functionality when resolving issues.
  C. Require the technicians to gather more information when speaking with users about issues.
  D. Require the technicians to document the findings, action, and outcomes of issues.
  D. Require the technicians to document the findings, action, and outcomes of issues.

  ---

  Explanation

  By documenting the findings, action, and outcomes of issues, the technicians can create a knowledge base that can be used to resolve similar issues in the future more quickly and efficiently. The documentation can also help identify patterns or trends that can lead to preventive measures or root cause analysis. Documenting the issues can also improve communication and collaboration among technicians and users, as well as provide evidence of service quality and performance.

• Question 988:

  A user regularly travels to multiple sites to take pictures with a mobile device and transfers those pictures to a computer via a removable SD card. Recently, the SD card was damaged and had to be replaced. Now, the user is unable to save pictures to the new SD card.

  Which of the following should the user verify first so pictures can be saved to the SD card?

  A. The card is correctly formatted.
  B. The card is a storage device.
  C. The card is not locked.
  D. The card is initialized.
  C. The card is not locked.

  ---

  Explanation

  When a user is unable to save pictures to a new SD card after replacing a damaged one, the first thing to check is whether the card is locked. Many SD cards have a physical switch on the side that can be toggled to a "locked" position, which prevents data from being written to the card. Ensuring the switch is in the "unlocked" position allows the device to save data to the SD card.

• Question 989:

  A technician replaced a failed PSU on a high-end workstation PC. Now, the PC fails to POST and does not stay turned on for more than five seconds.

  Which of the following power connections was most likely forgotten during installation?

  A. 5V
  B. 12V
  C. 120V
  D. 220V
  B. 12V

  ---

  Explanation

  The issue described suggests the 12V CPU power connector was likely forgotten during installation. The 12V power rail is essential for the operation of high-end workstation components, including the CPU. Without the 12V connection, the system will fail to POST and may power off shortly after being turned on.
