- A
Apply prompt engineering with few-shot examples and set temperature to 0
Why wrong: Prompt engineering and low temperature help but are insufficient alone; without external knowledge retrieval, the model may still invent plausible-sounding but incorrect medical facts.
- B
Use a larger LLM and increase the temperature parameter to improve creativity
Why wrong: Higher temperature increases randomness and can worsen hallucinations. Larger models still hallucinate without grounding.
- C
Implement RAG with a trusted medical knowledge base and use Bedrock Guardrails with contextual grounding check
RAG provides factual grounding by retrieving relevant documents, and Bedrock Guardrails' contextual grounding check validates response accuracy against the retrieved sources, significantly reducing hallucinations.
- D
Fine-tune the LLM on a large corpus of medical literature and use a higher temperature for diversity
Why wrong: Fine-tuning may reduce hallucinations but does not eliminate them, and higher temperature increases the chance of fabrication. The combination of RAG and guardrails is more robust.
AIF-C01 Practice Question: A healthcare startup is using an LLM to summarize…
This AIF-C01 practice question tests your understanding of aif-c01 exam topics. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A healthcare startup is using an LLM to summarize patient medical records. They are concerned about hallucinations where the model may invent symptoms or treatments. Which combination of techniques should they implement to reduce hallucinations while maintaining accuracy?
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
Implement RAG with a trusted medical knowledge base and use Bedrock Guardrails with contextual grounding check
Grounding the model with Retrieval-Augmented Generation (RAG) using verified medical databases and applying Bedrock Guardrails with contextual grounding checks directly reduces hallucinations by ensuring responses are based on retrieved facts and filtered for accuracy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Apply prompt engineering with few-shot examples and set temperature to 0
Why it's wrong here
Prompt engineering and low temperature help but are insufficient alone; without external knowledge retrieval, the model may still invent plausible-sounding but incorrect medical facts.

Why it's wrong here
Higher temperature increases randomness and can worsen hallucinations. Larger models still hallucinate without grounding.
- ✓

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
