    A. Check the local print queue for a failed print job.
    Explanation
    The user should check the local print queue for a failed print job because even though other users are not experiencing any problems, there may be a specific issue with the print job on the user's computer. Rebooting the computer twice did not resolve the issue, so it is necessary to investigate the print queue to see if there is a failed print job causing the problem. This will help identify and resolve any issues with the specific print job on the user's computer.

    • Replace the video card with a compatible one.

This suggests that there may be an issue with the boot order in the BIOS settings. By verifying the boot order in the BIOS, the technician can ensure that the computer is attempting to boot from the correct device, such as the CD drive, where the Windows XP Media Center installation files are located. This will allow the technician to properly configure Windows XP Media Center on the desktop.

    If a computer has an IP address of 169.254.6.15, which of the following has failed?

    • WINS

    • DHCP

    • DNS

    • NAT

    Correct Answer
    A. DHCP
    Explanation
    If a computer has an IP address of 169.254.6.15, it means that the computer was unable to obtain an IP address from a DHCP server. The IP address 169.254.x.x is allocated for Automatic Private IP Addressing (APIPA), which is used when a device is unable to connect to a DHCP server. Therefore, the failure lies with the DHCP service.

    A computer is not able to access Internet websites, internal company servers, or other networked resources. Which of the following is the FIRST step to help identify the cause of the problem?

    • Check the Ethernet link light.

    • Reboot the computer.

    • Check the length of the twisted-pair cable.

    • Ensure that a static IP address is assigned.

    Correct Answer
    A. Check the Ethernet link light.
    Explanation
    To help identify the cause of the problem, the first step is to check the Ethernet link light. This is because the Ethernet link light indicates whether there is a physical connection between the computer and the network. If the light is not lit, it suggests that there may be an issue with the physical connection, such as a loose cable or a faulty network port. By checking the Ethernet link light, we can determine if the problem lies in the physical connection, allowing us to troubleshoot and resolve the issue accordingly.

    Which of the following provides the BEST protection against ESD?

    • Proper grounding

    • A non-carpeted surface

    • An anti-static wrist strap

    • Rubber gloves

    Correct Answer
    A. An anti-static wrist strap
    Explanation
    An anti-static wrist strap provides the best protection against ESD (Electrostatic Discharge) because it is specifically designed to prevent the build-up and discharge of static electricity. It is worn on the wrist and connected to a grounded surface, effectively grounding the person and preventing the transfer of static electricity to sensitive electronic components. This helps to protect the components from damage that can be caused by ESD, ensuring their proper functioning and longevity.

    Which of the following may cause a touchpad to fail? (Select TWO).

    • A corrupt driver

    • A loose wire or connector

    • Dirt or oil on the touchpad

    • A corrupt video driver

    • An external keyboard

    Correct Answer(s)
    A. A corrupt driver
    A. A loose wire or connector
    Explanation
    A corrupt driver can cause a touchpad to fail because it may not be able to communicate properly with the operating system. This can result in the touchpad not responding or functioning correctly. A loose wire or connector can also cause a touchpad to fail as it may disrupt the connection between the touchpad and the motherboard, leading to a loss of functionality. Dirt or oil on the touchpad, a corrupt video driver, or an external keyboard are not directly related to causing a touchpad to fail.
