• Question 423:

  A technician is upgrading the power supply of a workstation that is running multiple GPUs in an SLI configuration. Which of the following cables is needed to ensure the power supply can support the workstation?

  A. 8-pin PCle
  B. 4-pin Molex
  C. 4+4-pin ATX12V
  D. 8-pin ATX12V
  A. 8-pin PCle

  ---

  Explanation

  The 8-pin PCle power cable is designed to supply power to a graphics card that requires more power than the PCle slot can provide. A workstation that is running multiple GPUs in an SLI configuration would need this cable to ensure adequate power delivery and stability. The other cables are not suitable for this purpose, as they are either meant for the motherboard (4+4-pin ATX12V and 8-pin ATX12V) or for older devices (4-pin Molex) https://superuser.com/ questions/849265/is-there-a-difference-between-8-pin- eps12v-and- pci-e-connectors

• Question 424:

  A technician is troubleshooting a computer that is not completing POST and gets stuck at the manufacturer logo screen. All internal, removable parts have been disconnected and only the minimum parts necessary to POST were

  reconnected.

  However, the symptoms remain the same. Which of the following should the technician try NEXT?

  A. Test the RAM in different slots, one at a time.
  B. Remove and test the power supply.
  C. Replace the motherboard.
  D. Change the CMOS battery.
  A. Test the RAM in different slots, one at a time.

  Explanation

  Every computer has a CMOS battery and when you remove that battery, your computer will work almost the same as before. The only difference is you won't be able to save any settings in the BIOS, which includes the date and time. If your PC is not booting after removing CMOS, you need to make sure that you have your CPU and RAM connected because it's not possible for your system to boot without those.. Your motherboard and computer will be able to boot just fine even without a CMOS battery present. The only issue is all your BIOS settings will be reset and the time and date will be inaccurate. You will also be unable to save BIOS settings.

• Question 425:

  A technician wants to block remote logins to a server. Which of the following ports should be blocked?

  A. 21
  B. 23
  C. 80
  D. 443
  A. 21

• Question 426:

  A user reports that files are taking hours to transfer from a device to an external USB drive. The technician confirms that the device's cables are connected and the correct USB port is being used.

  Which of the following steps should the technician take next when troubleshooting the issue?

  A. Turn off all Bluetooth devices.
  B. Update the device drivers.
  C. Replace the USB drive.
  D. Replace the device's USB port.
  B. Update the device drivers.

  ---

  Explanation

  When a device is experiencing slow file transfers to an external USB drive and the physical connections are confirmed to be correct, the next step is to update the device drivers. Outdated or corrupt drivers can cause suboptimal performance and slow transfer speeds. Updating the drivers can resolve these issues and improve the device's communication with the USB drive, leading to faster file transfers.

• Question 429:

  Numerous vendors implemented a feature in routers and access points that allows for automatically moving wireless clients between 2.4GHz and 5.0GHz frequencies based on user density and the distance from the wireless equipment. Which of the following describes this feature?

  A. Channel selection
  B. Near-field communication
  C. Propagation
  D. Band steering
  D. Band steering

  ---

  Explanation

  Band steering is a feature implemented in routers and access points to optimize wireless network performance by dynamically steering clients to the most appropriate frequency band (2.4GHz or 5GHz) based on factors such as user density and distance. This helps to balance client load across different frequency bands, improve overall network efficiency, and provide better performance for connected devices.
