- A
Increase the maxTokens parameter to allow more detailed descriptions.
Why wrong: More tokens give the model more freedom to generate incorrect information; it doesn't improve accuracy.
- B
Use a different foundation model from Bedrock for each product category.
Why wrong: Rotating models does not guarantee accuracy; all models may hallucinate without proper context.
- C
Deploy the model to a SageMaker endpoint and use human-in-the-loop validation.
Why wrong: Human validation adds cost and delay; it's a safety measure but not a proactive fix for hallucination.
- D
Include the product specifications in the prompt and instruct the model to base the description on the provided data.
Providing facts in the prompt grounds the model's output and reduces fabrication.
Quick Answer
The correct approach is to include the product specifications in the prompt and instruct the model to base the description on the provided data. This technique, known as prompt engineering with in-context learning, grounds the model’s output in factual information, directly reducing hallucinations by preventing the model from relying on its potentially inaccurate training data. On the AWS Certified AI Practitioner AIF-C01 exam, this scenario tests your understanding of how to improve factual accuracy in generative AI applications, a core concept in the Foundation Models and Prompt Engineering domain. A common trap is assuming you must fine-tune the model or use a different model altogether, but the simplest and most effective method is to enrich the prompt with the exact specs. Remember the memory tip: “Specs in the prompt, facts in the output”—if you want accurate product descriptions, feed the model the raw data it needs to describe.
AIF-C01 Applications of Foundation Models Practice Question
This AIF-C01 practice question tests your understanding of applications of foundation models. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An e-commerce company uses Amazon Bedrock to generate product descriptions from keywords. Some descriptions contain inaccurate details about product specifications. Which approach should the company take to reduce factual errors?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Include the product specifications in the prompt and instruct the model to base the description on the provided data.
Option D is correct because providing the product specifications directly in the prompt and instructing the model to base the description on that data grounds the generation in factual information, reducing hallucinations. This technique, known as prompt engineering with in-context learning, ensures the model uses the given data rather than relying on its training data, which may contain inaccuracies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the maxTokens parameter to allow more detailed descriptions.
Why it's wrong here
More tokens give the model more freedom to generate incorrect information; it doesn't improve accuracy.

Why it's wrong here
Human validation adds cost and delay; it's a safety measure but not a proactive fix for hallucination.
- ✓
Include the product specifications in the prompt and instruct the model to base the description on the provided data.
Why this is correct
Providing facts in the prompt grounds the model's output and reduces fabrication.

Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that increasing model parameters or changing models alone improves factual accuracy, when in fact prompt engineering with grounded data is the most effective and efficient method to reduce hallucinations.
Detailed technical explanation
How to think about this question
Under the hood, foundation models like those in Bedrock generate text by predicting tokens based on the input prompt; including explicit specifications in the prompt biases the model's attention mechanism toward those tokens, reducing reliance on parametric knowledge. In a real-world scenario, an e-commerce company might use a structured prompt like 'Based on the following specifications: [specs], generate a product description' to ensure the model outputs only what is provided, effectively turning the model into a data-to-text generator rather than a knowledge retriever.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
