  1. A user reports their laptop battery drains very quickly even after a full charge. What is the BEST diagnostic step?

    Answer: Run a battery health report using powercfg /batteryreport

    powercfg /batteryreport generates a detailed HTML report showing battery capacity, charge cycles, and degradation over time.

  2. A workstation fails to obtain an IP address automatically and shows a 169.254.x.x address. What does this indicate?

    Answer: DHCP server is unreachable and APIPA has assigned a self-link address

    A 169.254.x.x address is an APIPA (Automatic Private IP Addressing) address assigned when a DHCP server cannot be reached.

  3. A user accidentally deleted an important file and emptied the Recycle Bin. What is the BEST recovery option?

    Answer: Restore from a backup or use a file recovery tool immediately

    Restoring from backup is the safest option; if no backup exists, file recovery software can often recover data before it is overwritten.

  4. Which type of malware encrypts user files and demands payment for the decryption key?

    Answer: Ransomware

    Ransomware encrypts victim files and demands a ransom payment, typically in cryptocurrency, for the decryption key.

  5. A technician is setting up a new PC and wants to ensure Windows updates are current before delivering it. Which PowerShell command checks and installs Windows updates?

    Answer: Install-Module PSWindowsUpdate then Install-WindowsUpdate

    The PSWindowsUpdate module provides PowerShell cmdlets to check and install Windows updates from the command line.

  6. A user reports that their second monitor is not detected after connecting it via HDMI. What should the technician check FIRST?

    Answer: Check Display Settings to detect the monitor and verify cable connections

    Using Display Settings > Detect allows Windows to scan for the new display, and verifying cable seating rules out simple connection issues first.

  7. What is the purpose of the Windows System File Checker (SFC) tool?

    Answer: To scan and repair corrupted or missing Windows system files

    SFC /scannow scans protected system files and replaces corrupted files with cached copies from the Windows component store.
