WGU C954 Information Technology Management Ultimate Study Guide: 150
Most-Tested Practice Questions, Explanations, and Formulas for the Objective
Assessment (Version 8)
1. Which computer component is considered "volatile" because it requires power to
maintain stored data?
A) Solid State Drive (SSD)
B) Random Access Memory (RAM)
C) Read-Only Memory (ROM)
D) Hard Disk Drive (HDD)
RAM is primary storage that provides the CPU with working space; data is lost once
power is cut.
2. What is the primary role of the Operating System (OS)?
A) To create spreadsheets and documents
B) To manage hardware resources and provide a platform for applications
C) To protect the computer from all viruses without extra software
D) To host the company's website
The OS acts as the intermediary between the user, applications, and the physical
hardware.
3. In an enterprise, a "Thin Client" is a terminal that:
A) Has a very small physical footprint
B) Relies on a central server for most of its processing power
C) Is designed specifically for graphic designers
D) Functions entirely without an internet connection
Thin clients lower costs and increase security by centralizing data and processing.
4. Which network topology connects every node to every other node, providing high
redundancy?
A) Star Topology
B) Bus Topology
C) Mesh Topology
D) Ring Topology
Mesh networks are highly reliable but expensive and complex to wire physically.
,5. The Chief Information Officer (CIO) is primarily responsible for:
A) Fixing broken laptops in the office
B) Aligning IT strategic strategy with the overall business goals
C) Managing the physical security of the building
D) Writing the code for the company's mobile app
The CIO bridges the gap between the technical side of IT and the executive business
strategy.
6. Which type of software is designed for a specific industry, such as electronic
health records for doctors?
A) Horizontal Market Software
B) Vertical Market Software
C) System Software
D) Utility Software
Vertical software serves a specific "niche" or industry, unlike horizontal software like
Microsoft Word.
7. A "Gateway" in a network environment is used to:
A) Connect two identical computers
B) Connect two networks that use different protocols
C) Boost the Wi-Fi signal in a large house
D) Store large amounts of backup data
A gateway acts as a "translator" between different network architectures.
8. Secondary storage (like an SSD or HDD) is different from primary storage (RAM)
because it is:
A) Much faster
B) Non-volatile (retains data without power)
C) Directly connected to the CPU's registers
D) Only used for temporary calculations
Secondary storage is used for long-term retention of files and programs.
9. What is a defining characteristic of Open Source software?
A) It is always free to use commercially
B) The source code is available for anyone to inspect or modify
C) It does not require an operating system to run
D) It is only developed by government agencies
, Open source refers to the "open" nature of the underlying code, not necessarily the
price.
10. A "Server" is best described as a computer that:
A) Is used by only one person at a time
B) Provides resources or services to other computers (clients) on a network
C) Has the largest monitor in the office
D) Only functions if it is connected to a printer
Servers "serve" data, applications, or web pages to "client" devices.
11. "SaaS" stands for Software as a Service. This model allows users to:
A) Build their own hardware
B) Access software applications over the internet via a subscription
C) Purchase software on a physical disc
D) Rent a physical server from a local store
SaaS eliminates the need for local installation and maintenance of software.
12. In data management, "Granularity" refers to:
A) The speed of the database
B) The level of detail in the data (fine vs. coarse)
C) The number of people allowed to see the data
D) The age of the data
Fine granularity is highly detailed; coarse granularity is summarized.
13. Which part of the CPU performs mathematical calculations and logic
comparisons?
A) Control Unit
B) Arithmetic Logic Unit (ALU)
C) Primary Cache
D) Register Area
The ALU is the "calculator" within the processor.
14. What is a "Data Warehouse"?
A) A physical building where servers are kept
B) A logical collection of information gathered from many operational databases
C) A folder on a desktop where old files are moved
D) An encrypted USB drive used by the CEO
Warehouses aggregate data from across the company for high-level business analysis.
