  1. What does 'virtualization' allow a single physical computer to do?

    Answer: Run multiple operating systems simultaneously as virtual machines

    Virtualization allows one physical computer to run multiple operating systems simultaneously by creating isolated virtual machines managed by a hypervisor.

  2. Which component in a laptop is most commonly replaced to upgrade performance without changing the device?

    Answer: RAM and/or SSD

    RAM and SSD are the most commonly replaceable components in laptops, offering significant performance improvements that are accessible to most users.

  3. What is the purpose of cable management in a computer case or server rack?

    Answer: Improve airflow, organization, and ease of maintenance

    Proper cable management improves airflow for cooling, makes the system easier to service, and keeps the workspace organized.

  4. A server needs to remain accessible even if one hard drive fails. Which solution best addresses this?

    Answer: Implement RAID with redundancy (RAID 1, 5, or 10)

    RAID configurations with redundancy (such as RAID 1, 5, or 10) allow a server to continue operating even if one drive fails.

  5. Which of the following is an example of a WAN (Wide Area Network)?

    Answer: The internet

    The internet is the largest example of a WAN, connecting networks across vast geographic distances worldwide.

  6. What happens when a CPU's thermal paste dries out or is improperly applied?

    Answer: The CPU overheats due to poor heat transfer to the cooler

    Thermal paste fills microscopic gaps between the CPU and heatsink; when it dries or is missing, heat transfer degrades and the CPU overheats.

  7. Which cloud service model provides virtualized computing resources like VMs, storage, and networking over the internet?

    Answer: IaaS (Infrastructure as a Service)

    IaaS (Infrastructure as a Service) provides virtualized hardware resources — servers, storage, and networking — over the internet, letting users manage their own OS and apps.
