1. Which two considerations would be of the greatest importance when building a workstation that will run multiple virtual machines? (Choose two.)

   • amount of RAM
   • number of CPU cores
   • water cooling
   • powerful video card
   • high-end sound card
     

     Explanation & Hint: Virtual computing requires more powerful hardware configurations because each installation needs its own resources and thus requires a lot of RAM and CPU processing power.

2. Match the RAID technology terms to the description. (Not all options are used.)

   

   Explanation & Hints: Double parity is connected to “provides fault tolerance for up to two failed drives”. This refers to RAID-6, which can handle two drives failing simultaneously without data loss. Mirroring is connected to “stores the same data on multiple drives simultaneously”. This is a description of RAID-1, where data is written identically to two drives, creating a mirrored set. Striping is connected to “enables data to be distributed across multiple drives”. This matches RAID-0, where data is split across drives, which can improve speed but does not provide fault tolerance. Parity is connected to “provides basic error checking and fault tolerance by storing checksums separately from data”. This is characteristic of RAID-5, which uses parity information to provide fault tolerance for a single drive failure.

3. Which two components are commonly replaced when a computer system with a newer motherboard is being upgraded? (Choose two.)

   • RAM
   • hard disk drive
   • CPU
   • optical drive

    • RAID
    • smart card reader
    • Thunderbolt connector
    • dual-fan power supply

    • Explanation & Hint: For a cloud provider that requires fault tolerance for large-scale data storage, RAID (Redundant Array of Independent Disks) is a crucial consideration. RAID configurations (such as RAID 1, RAID 5, or RAID 10) provide data redundancy and protection against hardware failures by distributing data across multiple drives. This ensures that if one drive fails, the data remains accessible, minimizing downtime and data loss.

    • RAID
    • motherboard that supports dual-channeling
    • smart card reader
    • Thunderbolt connector

    • Explanation & Hint: For a cloud provider that needs fault tolerance for large quantities of stored data, RAID (Redundant Array of Independent Disks) is a critical consideration. RAID provides data redundancy and improves reliability by distributing data across multiple drives. Common RAID configurations such as RAID 1 (mirroring), RAID 5 (striping with parity), and RAID 10 (striping and mirroring) help prevent data loss in case of disk failure, ensuring high availability and fault tolerance.

52. A technician is selecting a PC that will be used by an employee who wants to share a keyboard and mouse among three devices. What is a major consideration that needs to be taken into account?

    • KVM switch
    • motherboard that supports dual-channeling
    • smart card reader
    • Thunderbolt connector

    • Explanation & Hint: A KVM (Keyboard, Video, Mouse) switch allows a user to control multiple computers using a single keyboard and mouse. Since the employee wants to share these peripherals among three devices, a KVM switch is the most important consideration. It enables seamless switching between different systems without requiring multiple keyboards and mice, improving efficiency and reducing desk clutter.
