This document contains 70 original questions developed to reinforce the official course objectives of WGU D075 IT
Foundations. The questions address Hardware, Software, and Operating Systems, Networking, Internet, and Cloud
Computing, Data Management, Databases, and Security, and IT Governance, Business Alignment, and Emerging
Technologies. Content is designed to support professional competency and actual exam readiness for Professional
IT and Computer Science Students. All material is original and aligned with WGU D075 course materials,
foundational IT textbooks, and current CompTIA / ITIL industry standards for the 2026/2027 cycle.
Domain: Hardware, Software, and Operating Systems
1. The primary function of the central processing unit (CPU) is to:
A. Store data permanently for long-term retrieval
B. Execute instructions and perform calculations that drive all computing operations
C. Display graphical output to the user
D. Provide wireless network connectivity
Correct Answer: A
Rationale: The CPU is the primary component that fetches, decodes, and executes program instructions.
2. Random Access Memory (RAM) is classified as:
A. Non-volatile storage that retains data when power is removed
B. Volatile memory that temporarily holds data and instructions the CPU is actively using
C. A type of optical storage media
D. A permanent solid-state drive
Correct Answer: A
Rationale: RAM is volatile; its contents are lost when power is turned off.
3. Which storage device typically offers the fastest data access times among common options?
A. Traditional hard disk drive (HDD)
B. Solid-state drive (SSD)
C. Optical Blu-ray disc
D. Magnetic tape archive
Correct Answer: A
Rationale: SSDs have no moving parts and provide significantly lower latency than HDDs or optical media.
4. An operating system’s kernel is responsible for:
A. Only the graphical user interface
B. Managing hardware resources, process scheduling, and providing core services to applications
C. Creating spreadsheet documents
D. Designing network cables
Correct Answer: D
Rationale: The kernel is the central component that controls hardware and mediates between software and devices.
5. Firmware is best described as:
A. Application software installed by the end user

, B. Software permanently stored in non-volatile memory that provides low-level control of hardware
C. A type of cloud-based productivity suite
D. Temporary data held only in RAM
Correct Answer: C
Rationale: Firmware (e.g., BIOS/UEFI) resides in non-volatile memory and initializes hardware at boot.
6. A 64-bit operating system differs from a 32-bit operating system primarily in that it:
A. Cannot run any 32-bit applications
B. Can address a significantly larger amount of memory and process wider data paths
C. Requires no hardware drivers
D. Is limited to text-only interfaces
Correct Answer: B
Rationale: 64-bit architectures support larger address spaces and more efficient processing of larger data units.
7. Virtual memory allows an operating system to:
A. Eliminate the need for any physical RAM
B. Use disk space to extend the available address space beyond physical RAM
C. Replace the CPU with software emulation
D. Disable all multitasking
Correct Answer: B
Rationale: Virtual memory maps logical addresses to physical RAM and secondary storage, enabling larger working sets.
8. Device drivers serve the purpose of:
A. Replacing the operating system kernel
B. Translating operating-system requests into commands that specific hardware devices understand
C. Storing user documents
D. Providing internet browser functionality
Correct Answer: D
Rationale: Drivers act as the software interface between the OS and individual hardware components.
9. Open-source software is characterized by:
A. Source code that is proprietary and never shared
B. Source code that is freely available for inspection, modification, and redistribution under defined licenses
C. Software that can only be used on a single device
D. Software that requires no license of any kind
Correct Answer: C
Rationale: Open-source licenses grant users the right to view, change, and share the source code.
10. The boot process of a modern PC typically begins with:
A. Loading the user’s desktop applications
B. Execution of firmware (UEFI/BIOS) that performs hardware initialization and locates the bootloader
C. Starting the web browser
D. Mounting network shares only
Correct Answer: C
Rationale: Firmware runs first, initializes hardware, and hands control to the bootloader that starts the OS.
11. Multitasking in an operating system refers to:
A. Running only one process at a time
B. The ability of the OS to manage multiple processes concurrently by rapidly switching the CPU among them
C. Using multiple physical CPUs exclusively for one application
D. Disabling all background services
Correct Answer: C
Rationale: Multitasking gives the appearance of simultaneous execution through time-slicing and scheduling.
12. A solid-state drive (SSD) stores data using:
A. Spinning magnetic platters
B. Flash memory cells with no moving parts
C. Optical lasers and reflective discs
D. Magnetic tape reels
Correct Answer: D
