Reuse of standardized prompt templates

Parameterization of prompts with dynamic inputs

Consistent instruction application across use cases

AWS Bedrock guidance describes prompt management as the recommended solution for maintaining reusable prompt templates while injecting product-specific content.

Why the other options are incorrect:

Knowledge Bases (B) provide retrieval, not prompt templating.

Model evaluation (C) assesses quality, not generation.

Cross-region inference (D) addresses availability, not prompt reuse.

Amazon Textract is a service that automatically extracts text and data from scanned documents, including PDFs. It is the best choice for converting resumes from PDF format to plain text for further processing.

Amazon Textract:

Extracts text, forms, and tables from scanned documents accurately.

Ideal for automating the process of converting PDF resumes into plain text format.

Why Option A is Correct:

Automation of Text Extraction: Textract is designed to handle large volumes of documents and convert them into machine-readable text, perfect for the company ' s need.

Scalability and Efficiency: Supports scalability to handle a growing volume of resumes as the company expands.

Why Other Options are Incorrect:

B. Amazon Personalize: Used for creating personalized recommendations, not for text extraction.

C. Amazon Lex: A service for building conversational interfaces, not for processing documents.

D. Amazon Transcribe: Used for converting speech to text, not for extracting text from documents.

The correct answer is C because Amazon Bedrock ' s model evaluation feature allows users to compare outputs from different foundation models using human evaluation or automatic metrics. It enables the creation of structured evaluations where human reviewers (in this case, scientists) can assess model responses based on custom criteria like relevance, coherence, or accuracy.

From AWS documentation:

" Amazon Bedrock provides model evaluation capabilities that support both automatic and human evaluation. You can define custom evaluation prompts and collect assessments from reviewers to compare foundation model outputs for tasks such as summarization, text generation, and more. "

This solution is ideal for research workflows requiring domain experts to provide feedback on LLM-generated content.

Explanation of other options:

A. Amazon Personalize is used for building recommendation systems, not for evaluating model output.

B. Amazon Rekognition is used for analyzing images and videos (e.g., moderation, facial recognition), not textual output.

D. Amazon Comprehend provides NLP services like sentiment analysis, but sentiment is not sufficient for full quality evaluation of research paper generation.

The correct answer is C because Amazon SageMaker JumpStart provides administrative controls that allow organizations to manage and restrict access to foundation models within the AWS environment.

According to the official AWS documentation:

" Amazon SageMaker JumpStart provides model access management capabilities that enable administrators to control which foundation models are visible and usable by end users. Using AWS Identity and Access Management (IAM) policies, you can restrict access to specific models or completely disable model discovery in JumpStart. "

This allows companies to enforce governance over which FMs their users can see and interact with, satisfying the requirement to control employee access to publicly available foundation models.

Explanation of other options:

A. AWS Cost Explorer is used to analyze billing and usage data but does not control access to services or models. It is helpful for budgeting and visibility, not access control.

B. AWS Artifact provides access to compliance reports and certifications, not tools for controlling user access to ML models.

D. Amazon OpenSearch Service is used for search and analytics on structured and unstructured data. It does not provide access control mechanisms for foundation models.
