Amazon Web Services AWS Certified AI Practitioner AIF-C01 New Questions

 Block input prompts or model responses that contain harmful content such as hate, insults, violence, or misconduct:Content filters

 Avoid subjects related to illegal investment advice or legal advice:Denied topics

 Detect and block specific offensive terms:Word filters

 Detect and filter out information in the model’s responses that is not grounded in the provided source information:Contextual grounding check

The company is using a generative AI model on Amazon Bedrock and needs to mitigate undesirable and potentially harmful content in the model’s responses. Amazon Bedrock provides several guardrail mechanisms, including content filters, denied topics, word filters, and contextual grounding checks, to ensure safe and accurate outputs. Each mitigation action in the hotspot aligns with a specific Bedrock filter policy, and each policy must be used exactly once.

Exact Extract from AWS AI Documents:

From the AWS Bedrock User Guide:

*"Amazon Bedrock guardrails provide mechanisms to control model outputs, including:

Content filters: Block harmful content such as hate speech, violence, or misconduct.

Denied topics: Prevent the model from generating responses on specific subjects, such as illegal activities or advice.

Word filters: Detect and block specific offensive or inappropriate terms.

Contextual grounding check: Ensure responses are grounded in the provided source information, filtering out ungrounded or hallucinated content."*(Source: AWS Bedrock User Guide, Guardrails for Responsible AI)

Detailed Explanation:

Block input prompts or model responses that contain harmful content such as hate, insults, violence, or misconduct: Content filtersContent filters in Amazon Bedrock are designed to detect and block harmful content, such as hate speech, insults, violence, or misconduct, ensuring the model’s outputs are safe and appropriate. This matches the first mitigation action.

Avoid subjects related to illegal investment advice or legal advice: Denied topicsDenied topics allow users to specify subjects the model should avoid, such as illegal investment advice or legal advice, which could have regulatory implications. This policy aligns with the second mitigation action.

Detect and block specific offensive terms: Word filtersWord filters enable the detection and blocking of specific offensive or inappropriate terms defined by the user, making them ideal for this mitigation action focused on specific terms.

Detect and filter out information in the model’s responses that is not grounded in the provided source information: Contextual grounding checkThe contextual grounding check ensures that the model’s responses are based on the provided source information, filtering out ungrounded or hallucinated content. This matches the fourth mitigation action.

Hotspot Selection Analysis:

The hotspot lists four mitigation actions, each with the same dropdown options: "Select...," "Content filters," "Contextual grounding check," "Denied topics," and "Word filters." The correct selections are:

First action: Content filters

Second action: Denied topics

Third action: Word filters

Fourth action: Contextual grounding check

Each filter policy is used exactly once, as required, and aligns with Amazon Bedrock’s guardrail capabilities.

This scenario demonstrates intellectual property (IP) infringement, where an AI-generated artifact (a cloned voice) uses the identifiable traits of a person without permission. According to AWS Responsible AI practices, using a person’s likeness, image, or voice in generative AI systems requires explicit rights and consent. Foundation models trained or applied without respecting these ownership boundaries violate ethical and legal frameworks under IP law. The AWS documentation emphasizes that generative AI must respect copyrighted or trademarked works and human likenesses. Responsible deployment requires consent-based data usage, license tracking, and content watermarking to prevent misappropriation. AWS Bedrock enforces such compliance principles through Guardrails and policy-based moderation to ensure content generation aligns with ethical and lawful standards.

The correct answer is B – Data preprocessing, which involves cleaning, filtering, and transforming raw data before model training. AWS defines preprocessing as the step where irrelevant or poor-quality data (e.g., excessively short or misrecorded audio) is removed or normalized. The described task—filtering recordings by duration and language—is a textbook example of preprocessing since it prepares the dataset for downstream feature extraction. Feature engineering would occur afterward when converting audio signals into numerical representations (like Mel-frequency coefficients). Model training and data collection come after and before preprocessing respectively. Proper preprocessing ensures data consistency, reduces noise, and improves model accuracy, especially in audio-based healthcare models where clarity and consistency are critical.

The correct answer is C because Amazon Bedrock Guardrails provides out-of-the-box configurable safety mechanisms to control the behavior of LLMs in generative AI applications. Guardrails can be configured with denylists, content filters, sensitive topics, and tone enforcement, all without retraining the model.

From AWS documentation:

"Amazon Bedrock Guardrails allows developers to define safety and responsible AI policies directly in the model inference layer, making it easy to prevent harmful, biased, or unsafe outputs with minimal configuration."

Explanation of other options:

A. Bedrock playgrounds are interactive environments for testing prompts and models but do not provide production-grade safety enforcement.

B. SageMaker Clarify focuses on bias detection and explainability for supervised ML models — it does not directly apply guardrails to LLM outputs.

D. SageMaker JumpStart is for model fine-tuning and deployment, not for enforcing safety policies on LLM responses.
