    A printer on the second floor is not printing for anyone. However, the printer has power and displays ready on the LCD display. There is paper in the trays and the toner was recently changed. The system administrator goes to the location with a laptop and tests the network port and is able to connect. Jobs are being queued on the local machines. Which of the following should the system administrator do to get the printer functioning again?

    • Move the printer to a known good port and connect to the network

    • Replace the network cable to the printer

    • Verify the server’s print spooler service is running

    • Attach the printer directly to the laptop and print a test page

    Correct Answer
    A. Verify the server’s print spooler service is running
    Explanation
    The system administrator should verify the server's print spooler service is running. This is because all the other components necessary for printing, such as power, paper, toner, and network connectivity, are already confirmed to be working properly. The issue could be related to the print spooler service, which manages the print queue and sends print jobs to the printer. By checking and ensuring that the print spooler service is running on the server, the administrator can troubleshoot and resolve any potential issues with the printing functionality.

    A technician is building a workstation that will only be used to connect remotely to a server. Which of the following types of PC configurations is BEST suited for this task?

    • Thin client

    • Home server PC

    • CAD workstation

    • AV workstation

    Correct Answer
    A. Thin client
    Explanation
    A thin client is the best suited PC configuration for a workstation that will only be used to connect remotely to a server. Thin clients are designed to rely heavily on the server for processing power and storage, allowing users to access applications and data remotely. They are lightweight, energy-efficient, and cost-effective, making them ideal for tasks that require minimal local processing but rely on server resources for most operations. This configuration ensures efficient remote connectivity without the need for a powerful standalone workstation.

    A user is watching streaming video on a home network, but experiences buffering and delays when there are too many people on the network. Which of the following is MOST likely to resolve the issue?

    • Disable SSID broadcast

    • Setup UPnP

    • Enable QoS

    • Configure DMZ

    Correct Answer
    A. Enable QoS
    Explanation
    Enabling Quality of Service (QoS) is the most likely solution to resolve the buffering and delays caused by too many people on the home network. QoS allows for prioritization of network traffic, ensuring that the streaming video traffic is given higher priority over other activities on the network. This will help to allocate sufficient bandwidth for the streaming video, reducing buffering and delays. Disabling SSID broadcast, setting up UPnP, or configuring DMZ are unrelated to the issue of network congestion caused by multiple users and would not directly resolve the problem.

    A small office would like to offer Internet access to customers while onsite. However, customers should not be able to access any corporate data. Which of the following networking features would BEST enable this?

    • Configure a guest wireless network

    • Implement a DMZ

    • Disable NAT on the wireless network

    • Disable the SSID

    • Assign static IPs for all devices

    Correct Answer
    A. Configure a guest wireless network
    Explanation
    A guest wireless network would be the best networking feature to enable in this scenario. By setting up a guest wireless network, the small office can provide internet access to customers while keeping them isolated from the corporate data. This ensures that customers can only access the internet and not any sensitive information or resources within the office's network.

    A customer wants the thinnest laptop possible. Which of the following display technologies typically allows for thinner devices?

    • IPS

    • OLED

    • LCD

    • DisplayPort

    Correct Answer
    A. OLED
    Explanation
    OLED (Organic Light Emitting Diode) display technology typically allows for thinner devices compared to other display technologies like IPS (In-Plane Switching) and LCD (Liquid Crystal Display). This is because OLED displays do not require a backlight like LCD displays, allowing for a thinner and more flexible design. OLED technology also offers better color reproduction, higher contrast ratios, and faster response times, making it a preferred choice for customers who prioritize thinness and display quality. DisplayPort, on the other hand, is a video interface standard and not a display technology, so it does not directly affect the thickness of a device.
