AWS Certified AI Practitioner AIF-C01 Passing Score

To manage the flow of data from Amazon S3 to SageMaker Studio notebooks securely, using a VPC with an S3 endpoint is the best solution.

Amazon SageMaker and S3 Integration:

Configuring SageMaker to use a Virtual Private Cloud (VPC) with an S3 endpoint allows the data flow between Amazon S3 and SageMaker Studio notebooks to occur over a private network.

This setup ensures that traffic between SageMaker and S3 does not traverse the public internet, enhancing security and performance.

Why Option C is Correct:

Secure Data Transfer: Ensures secure, private connectivity between SageMaker and S3, reducing exposure to potential security risks.

Direct Access to S3: Using an S3 endpoint in a VPC allows direct access to data in S3 without leaving the AWS network.

Why Other Options are Incorrect:

A. Amazon Inspector: Focuses on identifying security vulnerabilities, not managing data flow.

B. Amazon Macie: Monitors for sensitive data but does not manage data flow between S3 and SageMaker.

D. S3 Glacier Deep Archive: Is a storage class for archiving data, not for managing active data flow.

Generative Pre-trained Transformers (GPT) are suitable for building an AI-based application that can generate SQL queries from natural language input provided by employees.

GPT for Natural Language Processing:

GPT models are designed for understanding and generating human-like text based on natural language input.

They can be fine-tuned to interpret specific tasks, such as converting natural language queries into SQL queries.

Why Option A is Correct:

Natural Language Understanding: GPT is highly effective for tasks that require understanding of human language and generating structured outputs like SQL.

User-Friendly: Requires minimal technology experience from employees, as they provide simple text input.

Why Other Options are Incorrect:

B. Residual neural network: Typically used in computer vision tasks, not for natural language-to-SQL conversion.

C. Support vector machine: Used for classification tasks, not for generating structured queries from text.

D. WaveNet: A deep generative model for audio data, unrelated to text-to-SQL tasks.

Amazon SageMaker Clarify provides transparency and explainability for machine learning models by generating metrics, reports, and examples that help to understand model predictions. For a medical company that needs a foundation model to be transparent and explainable to meet regulatory requirements, SageMaker Clarify is the most suitable solution.

Amazon SageMaker Clarify:

It helps in identifying potential bias in the data and model, and also explains model behavior by generating feature attributions, providing insights into which features are most influential in the model's predictions.

These capabilities are critical in medical applications where regulatory compliance often mandates transparency and explainability to ensure that decisions made by the model can be trusted and audited.

Why Option B is Correct:

Transparency and Explainability: SageMaker Clarify is explicitly designed to provide insights into machine learning models' decision-making processes, helping meet regulatory requirements by explaining why a model made a particular prediction.

Compliance with Regulations: The tool is suitable for use in sensitive domains, such as healthcare, where there is a need for explainable AI.

Why Other Options are Incorrect:

A. Amazon Inspector: Focuses on security assessments, not on explainability or model transparency.

C. Amazon Macie: Provides data security by identifying and protecting sensitive data, but does not help in making models explainable.

D. Amazon Rekognition: Used for image and video analysis, not relevant to making models explainable.

Thus, B is the correct answer for meeting transparency and explainability requirements for the foundation model
