  1. A user's computer is unusually slow and CPU usage is at 100% with no obvious processes visible. What should you suspect?

    Answer: Malware infection

    Malware frequently runs hidden background processes that consume CPU resources without appearing prominently in Task Manager.

  2. After installing a new application, a user receives a 'missing DLL' error. What is the MOST appropriate fix?

    Answer: Install the required Visual C++ Redistributable or runtime package

    Missing DLL errors typically indicate an absent runtime library dependency that can be resolved by installing the correct redistributable package.

  3. A technician needs to remotely access a Windows computer to troubleshoot it. Which built-in Windows feature enables this?

    Answer: Remote Desktop Protocol (RDP)

    RDP (Remote Desktop Protocol) allows technicians to remotely control a Windows system over the network using port 3389.

  4. A user reports that their USB flash drive is not recognized by any PC. What is the FIRST step to diagnose?

    Answer: Test the drive on another known-working USB port

    Testing on a different port first rules out a faulty port before concluding the drive itself has failed.

  5. Which Windows command displays current TCP/IP network configuration including IP address, subnet mask, and default gateway?

    Answer: ipconfig /all

    ipconfig /all displays full TCP/IP configuration details for all network adapters on the system.

  6. A user's PC gives a 'NTLDR is missing' error on boot. What does this indicate?

    Answer: The boot sector or boot files are corrupted or missing

    NTLDR is the Windows boot loader; its absence means boot files are missing or the boot sector is damaged, requiring repair via installation media.

  7. A technician needs to determine which process is using a specific network port on a Windows machine. Which command is MOST useful?

    Answer: netstat -ano

    netstat -ano lists active connections with the associated process ID (PID), allowing you to identify which process owns each port.
