SECTION 1: GENERATIVE AI FUNDAMENTALS Questions 1-40
QUESTION 1
What is generative AI?
Options:
- AI systems that analyze existing data and generate reports
- AI systems that create new content based on patterns learned from training
data
- AI systems that only recognize patterns in data
- AI systems that replace human decision-making entirely
Correct Answer: AI systems that create new content based on patterns learned
from training data
Rationale: Generative AI creates new content—text, images, audio, code, and
more—by learning patterns from vast training datasets. The first option
describes analytical AI, not generative. The third option describes pattern
recognition, which is a component but not the full definition. The fourth
option overstates the capability and purpose of generative AI.
QUESTION 2
What is a Large Language Model (LLM)?
Options:
- A model that translates languages
- A type of generative AI trained on vast amounts of text data to understand and
1
, generate human-like language
- A model that only generates code
- A model that processes images
Correct Answer: A type of generative AI trained on vast amounts of text data to
understand and generate human-like language
Rationale: LLMs are trained on extensive text datasets to understand and
generate human-like language. The first option describes translation, which is
one application but not the definition. The third option is too narrow. The
fourth option describes computer vision models, not LLMs.
QUESTION 3
What is the key benefit of artificial intelligence in practical applications?
Options:
- Replacing all human workers
- Automating repetitive tasks, enabling data analysis at scale, generating
content, and assisting decision-making
- Making decisions without human input
- Reducing the need for creativity
Correct Answer: Automating repetitive tasks, enabling data analysis at scale,
generating content, and assisting decision-making
Rationale: AI's key benefits include automation, scalable data analysis,
content generation, and decision support. The first option is false—AI
augments rather than replaces humans entirely. The third option is incorrect
as AI typically assists, not replaces, human decision-making. The fourth
option is false—AI can enhance creativity.

,QUESTION 4
What is the difference between traditional programming and prompt
engineering?
Options:
- Traditional programming uses natural language; prompt engineering uses code
- Traditional programming uses code and rules; prompt engineering uses natural
language instructions to control model behavior
- There is no difference
- Traditional programming is obsolete
Correct Answer: Traditional programming uses code and rules; prompt
engineering
uses natural language instructions to control model behavior
Rationale: Traditional programming relies on explicit code and logical rules,
while prompt engineering uses natural language instructions to guide AI model
outputs. The first option reverses the relationship. The third option is
false. The fourth option is incorrect.
QUESTION 5
What is a "prompt" in the context of AI?
Options:
- A programming language
- The input text, instruction, or question provided to an AI system to elicit a
response
- The output generated by the AI
- The training data used to build the model
3
, Correct Answer: The input text, instruction, or question provided to an AI
system to elicit a response
Rationale: A prompt is the user's input—the instruction or question given to
an AI system. The first option is incorrect; prompts are not programming
languages. The third option describes the output, not the input. The fourth
option describes training data.
QUESTION 6
What is the primary goal of prompt engineering?
Options:
- Training a language model from scratch
- Crafting precise, effective inputs to guide AI toward accurate, relevant, and
high-quality responses without changing model weights
- Replacing human writers
- Making AI responses as long as possible
Correct Answer: Crafting precise, effective inputs to guide AI toward accurate,
relevant, and high-quality responses without changing model weights
Rationale: Prompt engineering focuses on designing inputs that elicit desired
outputs from pre-trained models without modifying the model itself. The first
option describes model training, not prompt engineering. The third option is
not a goal of prompt engineering. The fourth option is incorrect.
