Amazon Transcribe is the correct solution for converting audio from customer calls into text, allowing the company to analyze and extract key information from the conversations.

Amazon Transcribe:

It is a fully managed automatic speech recognition (ASR) service that converts speech into text, making it easier to perform text-based analysis on audio data.

After transcribing the audio, further analysis can be performed using other AWS services like Amazon Comprehend to extract insights such as sentiment, key phrases, or entities.

Why Option B is Correct:

Conversion to Text: Transcribing audio recordings is the first step in gaining insights from spoken conversations, allowing for further processing.

Enables Further Analysis: Once the audio is transcribed into text, other tools and services can be used to analyze the content more deeply.

Why Other Options are Incorrect:

A. Amazon Lex: Is used for building conversational interfaces, not for transcribing or analyzing audio from customer calls.

C. Amazon SageMaker Model Monitor: Monitors ML models for bias and data drift, not for audio analysis.

D. Amazon Comprehend: Can analyze text but cannot transcribe audio; it would be used after transcription is completed.

A multi-modal embedding model is the correct type of foundation model (FM) for powering a search application that handles queries containing both text and images.

Multi-Modal Embedding Model:

Can process and integrate different types of data (e.g., text and images) into a common representation space, enabling a unified search capability.

Suitable for applications where queries or content involve multiple data modalities.

Why Option A is Correct:

Handles Multiple Modalities: Supports both text and image data, aligning with the application's requirement.

Improves Search Relevance: Allows for more accurate and relevant search results across different types of input data.

Why Other Options are Incorrect:

B. Text embedding model: Only handles text data, not images.

C. Multi-modal generation model: Focuses on generating outputs rather than embedding for search tasks.

D. Image generation model: Only handles image data, not suitable for text queries.

The goal is to prevent a fine-tuned large language model (LLM) on Amazon Bedrock from revealing private customer data. Let’s analyze the options:

A. Amazon Bedrock Guardrails: Guardrails in Amazon Bedrock allow users to define policies to filter harmful or sensitive content in model inputs and outputs. While useful for real-time content moderation, they do not address the risk of private data being embedded in the model during fine-tuning, as the model could still memorize sensitive information.

B. Remove personally identifiable information (PII) from the customer data before fine-tuning the LLM: Removing PII (e.g., names, addresses, account numbers) from the training dataset ensures that the model does not learn or memorize sensitive customer data, reducing the risk of data leakage. This is a proactive and effective approach to data privacy during model training.

C. Increase the Top-K parameter of the LLM: The Top-K parameter controls the randomness of the model’s output by limiting the number of tokens considered during generation. Adjusting this parameter affects output diversity but does not address the privacy of customer data embedded in the model.

D. Store customer data in Amazon S3. Encrypt the data before fine-tuning the LLM: Encrypting data in Amazon S3 protects data at rest and in transit, but during fine-tuning, the data is decrypted and used to train the model. If PII is present, the model could still learn and potentially expose it, so encryption alone does not solve the problem.

Exact Extract Reference: AWS emphasizes data privacy in AI/ML workflows, stating, “To protect sensitive data, you can preprocess datasets to remove personally identifiable information (PII) before using them for model training. This reduces the risk of models inadvertently learning or exposing sensitive information.” (Source: AWS Best Practices for Responsible AI, https://aws.amazon.com/machine-learning/responsible-ai/). Additionally, the Amazon Bedrock documentation notes that users are responsible for ensuring compliance with data privacy regulations during fine-tuning (https://docs.aws.amazon.com/bedrock/latest/userguide/model-customization.html).

Removing PII before fine-tuning is the most direct and effective way to prevent the model from revealing private customer data, making B the correct answer.

Option B: Natural language processing (NLP)NLP focuses on processing and understanding text or speech, not visual data like product images. This option is incorrect.

Option C: Computer visionThis is the correct answer. Computer vision is used for tasks like defect detection in manufacturing by analyzing visual data to identify damages or defects.

Option D: Image processingWhile image processing involves manipulating images (e.g., filtering, resizing), it is a lower-level technique, not an AI application. Computer vision, which often uses image processing as a component, is the broader AI application here.

The company wants to fine-tune an ML model on Amazon Bedrock using sensitive data stored in private databases within a VPC, ensuring the data remains within its private network. AWS PrivateLink provides a secure, private connection between a VPC and AWS services like Amazon Bedrock, allowing data to stay within the company’s network without traversing the public internet. This meets the requirement for maintaining data privacy during fine-tuning.

Exact Extract from AWS AI Documents:

From the AWS Bedrock User Guide:

"AWS PrivateLink enables you to securely connect your VPC to Amazon Bedrock without exposing data to the public internet. This is particularly useful for fine-tuning models with sensitive data, as it ensures that data remains within your private network."

(Source: AWS Bedrock User Guide, Security and Networking)

Detailed Explanation:

Option A: Restrict access to Amazon Bedrock by using an AWS Identity and Access Management (IAM) service role.While IAM service roles control access to Amazon Bedrock, they do not address the requirement of keeping data within the private network during data transfer. This option is insufficient.

Option B: Restrict access to Amazon Bedrock by using an AWS Identity and Access Management (IAM) resource policy.IAM resource policies define permissions for Bedrock resources but do not ensure that data stays within the private network. This option is incorrect.

Option C: Use AWS PrivateLink to connect the VPC and Amazon Bedrock.This is the correct answer. AWS PrivateLink creates a secure, private connection between the VPC and Amazon Bedrock, ensuring that sensitive data does not leave the private network during fine-tuning, as required.

Option D: Use AWS Key Management Service (AWS KMS) keys to encrypt the data.While AWS KMS can encrypt data, encryption alone does not guarantee that data remains within the private network during transfer. This option does not fully meet the requirement.

The correct answer is A, as the most effective way to ensure fairness in AI systems is to audit and diversify training data. AWS Responsible AI documentation stresses that bias originates primarily from unbalanced or incomplete datasets. By including samples from all demographic groups, the model learns patterns that generalize fairly across populations. AWS SageMaker Clarify supports data bias detection and offers fairness metrics like demographic parity and equal opportunity difference. Deeper models (option B) or secrecy (option C) do not mitigate bias and may worsen transparency. Static test datasets (option D) fail to capture evolving data distributions. Therefore, ongoing bias reviews and diverse datasets form the foundation of responsible generative AI for financial use cases.

The correct answer is B – Adaptability and responsiveness, which are core strengths of generative AI models such as the foundation models available in Amazon Bedrock. According to AWS documentation, generative AI systems excel at understanding natural language variations, meaning they can interpret different phrasings, synonyms, sentence structures, and conversational styles while still generating contextually consistent answers. This capability comes from pretraining on diverse natural language corpora, allowing models to generalize across multiple linguistic patterns. AWS highlights that generative AI models are designed to handle “flexible, dynamic, and conversational inputs” and provide responses grounded in understanding user intent rather than matching exact keywords. Options A and D describe infrastructure performance characteristics, not the reasoning ability required for this use case. Option C (deterministic outputs) is incorrect because LLMs are inherently probabilistic and not fixed unless using advanced constraints. Therefore, generative AI’s adaptability to varied user phrasing makes it ideal for assistants requiring consistent, intent-based responses.

The correct answer is A – Create an AI agent. Amazon Bedrock Agents provide autonomous orchestration abilities that allow an AI system to interpret user queries, convert them into structured API calls, retrieve data, generate formatted outputs (like CSVs), and interact with external systems such as Amazon S3. According to AWS documentation, Bedrock Agents combine LLM reasoning with tool use, meaning they execute multi-step workflows such as querying OpenSearch, processing results, generating files, and uploading to storage—all without custom coding. The agent defines actions, APIs, and data transformation steps, making it ideal for automated enterprise workflows. Few-shot prompting (B) only influences text generation and cannot perform external actions like uploading to S3. A hand-coded software application (C) is possible but contradicts the goal of using AI for orchestration and requires more operational effort. A decision tree (D) cannot execute API workflows. Bedrock Agents are explicitly designed to perform multi-step tasks like this.
