Actual Exam Questions & Answers |
Grade A
This comprehensive preparation material is designed to help students pass the WGU D685
Practical Applications of Prompt Engineering exam on the first attempt. It includes a
curated test bank, realistic practice questions, and detailed explanations of core concepts.
Why You Need This Resource
Mastering prompt engineering requires moving beyond basic theory and understanding exactly
how AI models parse, interpret, and generate data. This exam description highlights the specific
domains and critical concepts you will confidently navigate using this guide.
Key Study Domains Covered
• Foundational Prompt Structures & PIIOA: Learn the five essential components of
an effective prompt: Persona, Instructions, Input, Output Format, and Additional
Information.
• Advanced AI Techniques: Master advanced techniques like Chain-of-Thought (CoT),
Few-Shot, Zero-Shot, and the Cognitive Verifier Pattern.
• AI Tool Selection: Distinguish which AI tools are best suited for specific business and
creative tasks, such as Optical Character Recognition (OCR), virtual assistants, and
image generators.
• Ethical AI & Bias: Understand the ethical principles required in AI, including
Transparency, Accountability, and Fairness, as well as how to identify and mitigate
measurement, selection, and algorithmic bias.
• Evaluating Model Outputs: Learn how to refine prompts by adding context,
specificity, and output constraints to transform vague, generic AI responses into highly
tailored results.
Format and Delivery Benefits

, • Realistic Exam-Style Questions: Practice with hundreds of verified, multiple-choice
questions that mirror the actual Objective Assessment (OA).
• Each Question Contains: Detailed correct Answer
• On-the-Go Accessibility: Study from anywhere with user-friendly, device-accessible
formats, ensuring you are fully prepared for exam day.
Q1. A student asked for 'recommendations for college.' To get better results,
what change should they make to the prompt? [Multiple Choice]
A) Provide few-shot examples
B) The student should include the motivation for the prompt.
C) Indicate the desired reading level
D) Choose a specific topic for the song
Answer: The student should include the motivation for the prompt.
Explanation: Including motivation (why they're asking for recommendations) helps the model
tailor suggestions to the student's goals and circumstances, improving relevance. Indicating
reading level is for simplifying or adjusting text complexity, choosing a song topic applies to lyric
prompts, and few-shot examples are a prompting technique to guide responses — none
specifically address improving college recommendations by revealing the student's underlying
reasons.
Q2. What advantage comes from including context and goals when writing a
prompt? [Multiple Choice]
A) More user-friendly interactions
B) Reduced need for clarifying exchanges
C) Adaptability and responsiveness
D) Facilitation of more accurate responses
Answer: Adaptability and responsiveness
Explanation: When a prompt supplies context and goals, the system can adapt its response style
and content to fit those specifics, making it more responsive and adaptable to different needs.
While detailed context often increases accuracy and can reduce clarifying exchanges or improve
user-friendliness, the core advantage emphasized here is the system's improved adaptability and
responsiveness to the user's objectives.

, Q3. If a prompt instructs the AI to respond 'in the form of song lyrics,' which
prompt component is being specified? [Multiple Choice]
A) Output format
B) Context
C) Chain of thought (COT)
D) Persona
Answer: Output format
Explanation: Telling the model the structure or style of the response (for example, to produce
song lyrics) defines the output format. Persona is about the role the model should take, context
provides background details, and Chain of thought is a prompting technique asking the model to
reveal its step-by-step reasoning — none describe the format of the answer itself.
Q4. Explain why emphasizing only the factors that support a favored prediction
is called confirmation bias, and describe the risk this bias creates for AI-assisted
market predictions. [Short Answer]
Answer: Confirmation bias is the tendency to emphasize evidence that supports a
preferred conclusion while downplaying or ignoring contradictory information; in AI-
assisted market predictions this results in skewed analyses and unreliable forecasts
because important opposing factors are discounted.
Explanation: A strong answer defines confirmation bias as selective emphasis on supporting
factors and then links that behavior to its consequence: distorted judgments and poorer decision-
making. For AI predictions, explain that feeding or privileging only confirming evidence can lead
models and analysts to overestimate favorable outcomes and miss warning signs.
Q5. When someone includes 'gluten-free' in a recipe prompt, which prompt
component are they providing? [Multiple Choice]
A) Motivation
B) Output format
C) Context
D) Persona
Answer: Context
Explanation: Adding dietary restrictions like 'gluten-free' gives the model background constraints
and relevant facts for generating appropriate recipes — that is context. Persona would tell the
