   A user arrives at the office and is unable to access the company's network on a smartphone. The user enables Wi-Fi on the smartphone, but it only shows the 5G symbol. Which of the following device settings should the user configure to fix this issue?

   • AAutoconnect
   • BVPN
   • CEncryption
   • DWPS

   Show answer

   Answer: A

   Explanation

   A. Autoconnect Explanation: 1. The smartphone is only showing the 5G symbol, which indicates that it is connected to a 5G network but not the company's network. 2. Enabling Wi-Fi on the smartphone suggests that the device is able to detect and connect to wireless networks, but it is not automatically connecting to the company's network. 3. The most likely issue is that the "autoconnect" or "auto-join" feature for the company's wireless network is not enabled on the smartphone. This feature allows the device to automatically connect to a known and preferred wireless network when it is in range. 3. By configuring the autoconnect or auto-join setting for the company's wireless network on the smartphone, the user can ensure that the device will automatically connect to the correct network when it is available, resolving the connectivity issue.

    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?

    • A5V
    • B12V
    • C120V

    Answer: B

    Explanation

    Explanation: 12V Power Connector: High-end workstation PCs often have a 12V power connector (usually a 4-pin or 8-pin connector) that provides additional power to the CPU. If this connection is not made, the system may fail to POST and power off shortly after turning on. Symptoms of Missing 12V Connection: The fact that the PC turns on for a few seconds and then shuts down suggests that the CPU is not receiving sufficient power, which is often linked to the 12V connector being disconnected.
