AIF-C01 Dumps with Practice Exam Questions Answers

Comprehensive and Detailed Explanation From Exact AWS AI documents:

Feature engineering focuses on:

Creating new features

Selecting the most relevant existing features

Improving model signal and accuracy

AWS ML best practices identify feature engineering as a key driver of predictive performance.

Why the other options are incorrect:

Visualization (A) helps understanding, not feature creation.

Hyperparameter tuning (B) optimizes models, not features.

Data collection (D) expands datasets but does not engineer features.

The correct answer is B. AWS Lambda can efficiently perform image processing and transformations, such as rotating, resizing, or transposing, in a serverless and event-driven manner. According to AWS documentation, Lambda functions can trigger automatically when new images are uploaded to Amazon S3, perform necessary transformations using libraries like Pillow or OpenCV, and store the processed outputs. This approach minimizes infrastructure management and scales automatically. Deep neural networks (option A) are excessive for simple transformations, while LLMs (option C) and Glue Data Quality (option D) are unrelated—LLMs handle text and Glue is for tabular data validation. Lambda is the AWS-recommended service for lightweight, automated image preprocessing tasks.

Network isolation is a key security feature for SageMaker. It ensures that training and inference jobs run in a VPC and are not accessible from the internet. Per the official SageMaker documentation:

“When you enable network isolation, your model can’t make any outbound network calls. This is useful for security and regulatory compliance when working with sensitive data.”

AWS Glue is a serverless data integration service that enables users to extract, transform, and load (ETL) data. For a company with minimal programming experience, Amazon Q Developer provides an AI-powered assistant that can generate code, explain AWS services, and guide users through tasks like creating AWS Glue jobs. This makes it an ideal tool to help the company use AWS Glue effectively.

Exact Extract from AWS AI Documents:

From the AWS Documentation on Amazon Q Developer:

"Amazon Q Developer is an AI-powered assistant that helps developers by generating code, answering questions about AWS services, and providing step-by-step guidance for tasks such as building ETL pipelines with AWS Glue. It is designed to assist users with varying levels of expertise, including those with minimal programming experience."

(Source: AWS Documentation, Amazon Q Developer Overview)

Detailed Explanation:

Option A: Amazon Q Developer

This is the correct answer. Amazon Q Developer can assist the company by generating AWS Glue scripts, explaining Glue concepts, and providing guidance on setting up ETL jobs, which is particularly helpful for users with limited programming experience.

Option B: AWS Config

AWS Config is used for tracking and managing resource configurations and compliance, not for assisting with coding or using services like AWS Glue. This option is incorrect.

Option C: Amazon Personalize

Amazon Personalize is a machine learning service for building recommendation systems, not for assisting with data integration or AWS Glue. This option is irrelevant.

Option D: Amazon Comprehend

Amazon Comprehend is an NLP service for analyzing text, not for helping users write code or use AWS Glue. This option does not meet the requirements.

The ML research team needs a mechanism to audit custom ML models while sharing model artifacts with other teams. Amazon SageMaker Model Cards provide a structured way todocument model details, including intended uses, training data, and inference performance, making them ideal for auditing and ensuring transparency when publishing models.

Exact Extract from AWS AI Documents:

From the Amazon SageMaker Developer Guide:

"Amazon SageMaker Model Cards enable you to document critical details about your machine learning models, such as intended uses, training data, evaluation metrics, and inference details. Model Cards support auditing by providing a centralized record that can be reviewed by teams to understand model behavior and limitations."

(Source: Amazon SageMaker Developer Guide, SageMaker Model Cards)

Detailed Explanation:

Option A: Create documents with the relevant information. Store the documents in Amazon S3.While storing documents in S3 is feasible, it lacks the structured format and integration with SageMaker that Model Cards provide, making it less suitable for auditing purposes.

Option B: Use AWS AI Service Cards for transparency and understanding models.AWS AI Service Cards are not a standard feature in AWS documentation. This option appears to be a distractor and is not a valid solution.

Option C: Create Amazon SageMaker Model Cards with Intended uses and training and inference details.This is the correct answer. SageMaker Model Cards are specifically designed to document model details for auditing, transparency, and collaboration, meeting the team’s requirements.

Option D: Create model training scripts. Commit the model training scripts to a Git repository.Sharing training scripts in a Git repository provides access to code but does not offer a structured auditing mechanism for model details like intended uses or inference performance.
