  1. A laptop's built-in keyboard stops working after a liquid spill, but an external USB keyboard works fine. What is the most cost-effective repair?

    Answer: Replace the laptop keyboard ribbon cable or keyboard assembly

    Liquid damage typically affects only the keyboard assembly; replacing the keyboard or its ribbon cable restores functionality without a costly motherboard swap.

  2. Which power supply specification describes its efficiency at converting AC input to DC output?

    Answer: 80 Plus certification

    80 Plus certification levels (Bronze, Silver, Gold, Platinum, Titanium) indicate the PSU's AC-to-DC conversion efficiency at various load levels.

  3. A technician is installing a CPU and notices one corner of the socket has a small triangle indicator. What does this indicate?

    Answer: CPU pin 1 alignment for correct installation orientation

    The triangle on both the CPU and socket marks pin 1, ensuring the processor is inserted in the correct orientation to avoid damage.

  4. A workstation needs to run four 4K monitors simultaneously. Which hardware consideration is most critical?

    Answer: GPU with sufficient video outputs and VRAM

    Driving four 4K displays requires a GPU with enough video outputs and VRAM to buffer and render all four high-resolution framebuffers.

  5. What is the function of the EPS 12V connector on a motherboard?

    Answer: Supplies dedicated 12V power to the CPU voltage regulator

    The EPS 12V (8-pin) connector delivers dedicated 12-volt power directly to the motherboard's CPU voltage regulator module.

  6. A technician suspects a hard drive is failing. Which built-in drive technology provides real-time health monitoring data?

    Answer: S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology)

    S.M.A.R.T. monitors drive health attributes such as reallocated sectors and spin-up time, providing early warning of potential failure.

  7. Which bus standard is used by modern CPUs to communicate directly with RAM, bypassing the traditional northbridge chipset?

    Answer: Integrated Memory Controller (IMC) on-die

    Modern CPUs include an on-die Integrated Memory Controller that connects directly to RAM, eliminating northbridge latency.
