AIF-C01 Practice Question: A team is deploying a sentiment analysis…
This AIF-C01 practice question tests your understanding of a team is deploying a sentiment analysis…. 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.
A team is deploying a sentiment analysis application using Amazon Bedrock. They need to ensure the model returns only 'positive', 'negative', or 'neutral'. Which prompt engineering technique is BEST suited for this requirement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Include an instruction like 'Classify the sentiment as one of: positive, negative, neutral. Output only that word.'
Constrained generation with a controlled vocabulary is achieved by instructing the model to output only specific tokens. Few-shot examples help but do not guarantee strict adherence; output parsing via Guardrails can enforce format but not specific vocabulary.
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.
✗
Use a chain-of-thought prompt to reason about sentiment
Why it's wrong here
Chain-of-thought improves reasoning, not output format control.
✗
Provide few-shot examples of the three labels in the prompt
Why it's wrong here
Few-shot examples encourage but do not enforce the output format strictly.
✗
Use a Bedrock Guardrail to block any response not matching the three labels
Why it's wrong here
Guardrails can filter after generation but are not a prompt engineering technique.
✓
Include an instruction like 'Classify the sentiment as one of: positive, negative, neutral. Output only that word.'
Why this is correct
Clear instruction with constrained output is the most direct prompt engineering technique.

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.
