A prompt template defines how the model is structured and guided (system prompts, roles, guardrails).

An attack that reveals or leaks this prompt template is known as a prompt extraction attack.

The other options (persona switching, exploiting friendliness, ignoring prompts) describe adversarial techniques but do not directly expose the internal configured behavior.

In generative AI models, such as those built on Amazon Bedrock, inference costs are driven by the number of tokens processed. A token can be as short as one character or as long as one word, and the more tokens consumed during the inference process, the higher the cost.

Option A (Correct): "Number of tokens consumed": This is the correct answer because the inference cost is directly related to the number of tokens processed by the model.

Option B: "Temperature value" is incorrect as it affects the randomness of the model's output but not the cost directly.

Option C: "Amount of data used to train the LLM" is incorrect because training data size affects training costs, not inference costs.

Option D: "Total training time" is incorrect because it relates to the cost of training the model, not the cost of inference.

AWS AI Practitioner References:

Understanding Inference Costs on AWS: AWS documentation highlights that inference costs for generative models are largely based on the number of tokens processed.

AWS HealthScribe provides speech-to-text and medical documentation generation, specifically designed for healthcare applications.

Amazon Polly is text-to-speech, not speech-to-text.

Amazon Rekognition is computer vision.

Amazon Q Developer is a generative AI assistant for developers, not healthcare.

AWS Glue is the correct service for transforming petabytes of unstructured data into a structured format suitable for machine learning tasks.

AWS Glue:

A fully managed extract, transform, and load (ETL) service that makes it easy to prepare and transform unstructured data into a structured format.

Provides a range of tools for cleaning, enriching, and cataloging data, making it ready for data scientists to use in ML models.

Why Option D is Correct:

Data Transformation: AWS Glue can handle large volumes of data and transform unstructured data into structured formats efficiently.

Integrated ML Support: Glue integrates with other AWS services to support ML workflows.

Why Other Options are Incorrect:

A. Amazon Lex: Used for building chatbots, not for data transformation.

B. Amazon Rekognition: Used for image and video analysis, not for data transformation.

C. Amazon Kinesis Data Streams: Handles real-time data streaming, not suitable for batch transformation of large volumes of unstructured data.

Real-time inference is designed to provide immediate, low-latency predictions, which is necessary when the company requires near real-time latency for its ML models. This option is optimal when there is a need for fast responses, even with large input data sizes and substantial processing times.

Option A (Correct): "Real-time inference": This is the correct answer because it supports low-latency requirements, which are essential for real-time applications where quick response times are needed.

Option B: "Serverless inference" is incorrect because it is more suited for intermittent, small-scale inference workloads, not for continuous, large-scale, low-latency needs.

Option C: "Asynchronous inference" is incorrect because it is used for workloads that do not require immediate responses.

Option D: "Batch transform" is incorrect as it is intended for offline, large-batch processing where immediate response is not necessary.

AWS AI Practitioner References:

Amazon SageMaker Inference Options: AWS documentation describes real-time inference as the best solution for applications that require immediate prediction results with low latency.

The correct answer is B because Amazon CloudWatch provides monitoring capabilities that include tracking usage metrics for Amazon Comprehend endpoints, such as invocation counts. You can configure CloudWatch to collect these metrics and create custom dashboards or alarms to report when an endpoint has zero usage over a period (e.g., 15 days).

From AWS documentation:

"Amazon CloudWatch enables you to collect and track metrics for Comprehend endpoints, create alarms, and automatically react to changes in your AWS resources."

This allows automated reporting and alerting for underused or idle endpoints.

Explanation of other options:

A. AWS Trusted Advisor focuses on general AWS resource optimization, security, and limits but does not track endpoint usage.

C. AWS CloudTrail tracks API calls but does not provide time-based monitoring or usage analysis over time.

D. AWS Config is used to track configuration changes and compliance, not endpoint usage metrics.

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.

Amazon SageMaker endpoints provide fully managed, serverless model deployment for real-time and batch predictions, allowing companies to deploy ML models without handling any servers or infrastructure management.

D is correct: SageMaker endpoints let you deploy, scale, and monitor ML models with no infrastructure overhead.

A and B require infrastructure management.

C (CloudFront/S3) is not for model deployment, but for static content delivery.

“Amazon SageMaker endpoints allow you to deploy machine learning models for inference without the need to manage underlying infrastructure.”

Model fine-tuning adapts a pre-trained model to a specific domain or task using labeled data. This is the preferred approach when you want highly customized behavior for a particular application or subject area.

(Reference: Amazon Bedrock Fine-Tuning)

Data augmentation is used to artificially increase the size of a labeled dataset, usually by transforming or generating variations of the original data. This helps improve model generalization when labeled data is limited.

(Reference: AWS Data Preparation Techniques, AWS AI Practitioner Guide)

Continued pre-training (also called domain-adaptive pre-training) further trains a foundation model on large amounts of unlabeled data from a specific domain, improving the model’s language understanding or generation for that domain.
