Retraining or pre-training is costly and unnecessary for just using company policies.

Fine-tuning adapts models but is inefficient for frequently changing company documents.

Retrieval-Augmented Generation (RAG) is the best approach — it retrieves relevant policy documents from a knowledge base and feeds them into the model context in real time, ensuring accurate and up-to-date responses.

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.

The correct answers are A and C because:

Amazon Transcribe converts spoken dialogue from video into text (captions or subtitles).

Amazon Translate translates that transcribed text into other languages.

Amazon Polly can then convert the translated text into lifelike speech for voice-overs in different languages.

From AWS documentation:

"Amazon Transcribe is used to create accurate speech-to-text transcripts. You can feed this text into Amazon Translate to support multilingual subtitles. To generate audio output, Amazon Polly provides neural text-to-speech in multiple languages."

Explanation of other options:

B. Amazon Textract is used for extracting text from documents/images, not audio or video, and is not applicable here.

D. Amazon Translate does not generate speech — it only translates text.

E. Amazon Textract does not generate audio.

The correct answer is D. Amazon Bedrock Agents are used to orchestrate and execute complex workflows by connecting foundation models with APIs, databases, and tools. According to AWS documentation, agents interpret user inputs, plan the necessary steps, call external APIs or systems, and return structured results. This allows the model to go beyond text generation into full automation workflows—such as booking tasks, querying internal systems, or summarizing reports. Option A describes multi-modal models, B refers to prompt tuning, and C misstates control delegation; agents act autonomously based on model reasoning. Thus, Bedrock Agents function as intelligent orchestrators, handling multi-step task execution through integrated tool use.

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.
