Amazon Web Services Updated AIF-C01 Exam Questions and Answers by fallon

Comprehensive and Detailed Explanation From Exact AWS AI documents:

BLEU is a widely used metric for evaluating machine translation by comparing machine-generated translations against reference (human) translations.

In this scenario:

Both systems are evaluated on the same dataset

The goal is to compare model output against human output

AWS ML evaluation guidance describes BLEU as suitable for relative comparison of translation quality across systems.

Why the other options are incorrect:

Absolute quality (A, C) is difficult to measure without human judgment.

BERTScore (D) is more computationally complex and less standard for operational comparisons.

The verified answer is A. Present the model Shapley values. AWS documentation states that SageMaker Clarify provides feature attributions based on Shapley values. These values can determine the contribution each feature made to model predictions and can be provided for individual predictions or at a global level for the model as a whole. That is exactly what stakeholders need when they ask for transparency and explainability: they need to understand which features influenced the model’s decisions and how strongly those features contributed.

AWS also explains that SageMaker Clarify helps explain how ML models make predictions and that transparency is critical for consumers and regulators. Clarify’s explainability uses a model-agnostic feature attribution approach and includes a scalable implementation of SHAP. These explanations answer practical stakeholder questions such as why the model made a prediction, how it makes predictions, and which features have the largest influence on model behavior.

Option B is incorrect because accuracy measures predictive correctness, not explainability. A model can be highly accurate while still being opaque. Accuracy alone does not show why a specific prediction was made.

Option C is incorrect because a confusion matrix summarizes classification performance by showing true positives, false positives, true negatives, and false negatives. It is useful for evaluation, but it does not explain individual feature influence or model reasoning.

Option D is incorrect because a secure inference endpoint protects access to the deployed model. Security is important, but it does not provide transparency or explainability.

Therefore, presenting Shapley values is the correct solution because it directly explains feature contributions to model predictions.

Comprehensive and Detailed Explanation From Exact AWS AI documents:

Amazon SageMaker Clarify is designed to detect and explain bias in ML models and datasets.

AWS Responsible AI guidance recommends Clarify to:

Identify bias in predictions

Analyze feature attribution

Support fairness and ethical AI practices

Why the other options are incorrect:

Rekognition (A) analyzes images, not recommendation bias.

Amazon Q Developer (B) assists developers with code.

Comprehend (C) performs NLP tasks, not bias analysis.

The business objective to evaluate the effect of an LLM chatbot aimed at reducing the actions required by call center employees should be average call duration.

Average Call Duration:

This metric measures the time taken to handle a customer call or query. A successful LLM chatbot should reduce the call duration by efficiently providing answers, minimizing the need for human intervention.

By decreasing the average call duration, the company can improve call center efficiency, reduce costs, and enhance the user experience.

Why Option B is Correct:

Direct Impact: The objective aligns directly with the goal of reducing the number of actions call center employees must take.

Operational Efficiency: Reducing call duration is a clear indicator of the chatbot ' s effectiveness in assisting customers without human help.

Why Other Options are Incorrect:

A. Website engagement rate: Is unrelated to call center operations.

C. Corporate social responsibility: Does not relate to call center efficiency.

D. Regulatory compliance: Is important but does not measure the effectiveness of a chatbot in reducing employee actions.
