B) The technology used in creating, maintaining, and making information accessible.
C) The physical construction of desktop computer towers only.
D) The process of strictly hiring human resources for technical support.
E) The manual entry of data into a paper ledger.
Correct Answer: B) The technology used in creating, maintaining, and making information
accessible.
Rationale: Information Technology is a broad field that encompasses all tools and methods
used to handle information. This includes the hardware, software, and networking
components that allow data to be generated, stored, protected, and retrieved by users
across various platforms.
Question 2
Which IT professional role is primarily responsible for maintaining all aspects of a computer
system, including hardware, software, and programming coordination?
A) Database Administrator
B) Security Administrator
C) System Administrator
D) Web Administrator
E) Network Administrator
Correct Answer: C) System Administrator
Rationale: A System Administrator (or SysAdmin) has the widest breadth of responsibility
among the administration roles. They ensure that the entire system—including the
operating system, server hardware, and installed software—functions correctly and stays
updated to meet the organization's needs.
Question 3
An IT professional who is specifically "in charge of all aspects of the computer network" is
known as the:
A) Support Professional
B) Network Administrator
C) Security Administrator
D) Database Administrator
E) System Analyst
, 2
Correct Answer: B) Network Administrator
Rationale: Network Administrators focus specifically on the connectivity of the
organization. Their duties include managing routers, switches, physical cabling, and
wireless protocols to ensure that computers and resources can communicate effectively with
one another.
Question 4
If an organization needs an expert to focus on the design, development, and support of Database
Management Systems (DBMSs), which role should they hire?
A) System Administrator
B) Security Administrator
C) Web Administrator
D) Database Administrator
E) IT Support Specialist
Correct Answer: D) Database Administrator
Rationale: Database Administrators (DBAs) specialize in how data is structured and stored.
They are responsible for the integrity, performance, and development of databases,
ensuring that information can be queried efficiently and safely.
Question 5
Which IT role is tasked with installing and configuring firewalls to protect systems and
proactively working to stop intrusions?
A) Web Administrator
B) Network Administrator
C) Security Administrator
D) System Administrator
E) Support Specialist
Correct Answer: C) Security Administrator
Rationale: Security Administrators are the defenders of the IT environment. Their primary
focus is cybersecurity, which involves setting up protective barriers like firewalls and
monitoring system logs to identify and neutralize potential threats before they cause
damage.
Question 6
A professional who installs, configures, maintains, secures, and troubleshoots web servers is
known as a:
A) Web Administrator
B) Network Architect
C) Database Developer
, 3
D) Security Analyst
E) Help Desk Technician
Correct Answer: A) Web Administrator
Rationale: Web Administrators (or Webmasters) focus on the specific hardware and
software that hosts websites. They ensure that the web server is accessible, secure from
web-based attacks, and optimized for performance so that users can access site content
without interruption.
Question 7
Which group of IT professionals is primarily responsible for help desk support and user training?
A) System Administrators
B) Support IT Professionals
C) Security Administrators
D) Database Administrators
E) Network Administrators
Correct Answer: B) Support IT Professionals
Rationale: Support IT Professionals act as the bridge between the technology and the end-
user. Their role is focused on troubleshooting individual user problems (help desk) and
educating users on how to use new systems or software effectively.
Question 8
What is the definition of "Information" in the context of IT?
A) Raw, unorganized facts.
B) Processed data.
C) The physical hardware used to store files.
D) A collection of computer protocols.
E) The electrical signals traveling through a bus.
Correct Answer: B) Processed data.
Rationale: While data consists of raw facts or symbols, information is the result of applying
a process to that data to make it meaningful. For example, a list of numbers is data; a chart
showing those numbers represent monthly sales is information.
Question 9
The transition of data to information, then to knowledge, and finally to wisdom is defined by the:
A) IPOS Cycle
B) TCP/IP Protocol
C) DIKW Hierarchy
D) OS Stack
E) System Clock
, 4
Correct Answer: C) DIKW Hierarchy
Rationale: The DIKW Hierarchy (Data, Information, Knowledge, Wisdom) represents the
path of human understanding. It shows how raw inputs (data) are refined into useful
results (information), which are then internalized through context (knowledge) and
eventually used to understand "why" things happen (wisdom).
Question 10
In the DIKW Hierarchy, which component is defined as "the input directly received by the user
or computer"?
A) Wisdom
B) Information
C) Knowledge
D) Data
E) Processing
Correct Answer: D) Data
Rationale: Data is the base of the hierarchy. It consists of raw signals or symbols that have
no inherent meaning on their own. It is generally not usable for decision-making until it has
been converted or processed into a more relevant form.
Question 11
Which level of the DIKW Hierarchy involves one or more processes being applied to data to
transform it into a more useful form?
A) Data
B) Information
C) Knowledge
D) Wisdom
E) Output
Correct Answer: B) Information
Rationale: Information is data that has been organized or inferred. By applying structure or
context to raw data, the resulting information becomes a tool that humans or systems can
use to understand a specific situation.
Question 12
In the DIKW Hierarchy, how is "Knowledge" defined?
A) Raw binary code stored on a hard drive.
B) Processed data presented in a graph.
C) Information that has been put to use or placed into a context.
D) The ability to understand the social setting of information.
E) Rules by which networks communicate.
