This AIF-C01 practice question tests your understanding of evaluating the performance of their…. 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 company is evaluating the performance of their question-answering model using Amazon Bedrock's model evaluation feature. They want to assess both the factual accuracy and the fluency of the generated answers. Which THREE metrics should they choose? (Select THREE.)
ROUGE
ROUGE measures n-gram recall, useful for factual overlap in QA.
BLEU
Why wrong: BLEU is primarily for machine translation, not QA.
BERTScore
BERTScore captures semantic similarity between generated and reference answers.
Human evaluation
Human evaluation can assess factual accuracy, fluency, and overall quality.
Exact match
Why wrong: Exact match is too rigid for open-ended QA where multiple correct phrasings exist.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
ROUGE
ROUGE measures overlap for summarization/QA; BERTScore measures semantic similarity; and human evaluation is the gold standard for fluency and factual accuracy. BLEU is for translation; exact match is too strict for open-ended QA.
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.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
