Amazon Web Services Updated AIF-C01 Exam Questions and Answers by leonie

AWS PrivateLink enables private connectivity between VPCs and AWS services without exposing traffic to the public internet. This feature is critical for meeting regulatory compliance standards that require isolation from public internet traffic.

Option A (Correct): "AWS PrivateLink": This is the correct answer because it allows secure access to Amazon Bedrock and other AWS services from a VPC without internet access, ensuring compliance with regulatory standards.

Option B: "Amazon Macie" is incorrect because it is a security service for data classification and protection, not for managing private network traffic.

Option C: "Amazon CloudFront" is incorrect because it is a content delivery network service and does not provide private network connectivity.

Option D: "Internet gateway" is incorrect as it enables internet access, which violates the VPC's no-internet-traffic policy.

AWS AI Practitioner References:

AWS PrivateLink Documentation: AWS highlights PrivateLink as a solution for connecting VPCs to AWS services privately, which is essential for organizations with strict regulatory requirements.

The company needs to address the degradation in model inference quality after 4 months in production and prevent future occurrences by receiving notifications. Retraining the model can address the current degradation, likely caused by data drift (changes in the data distribution over time). Amazon SageMaker Model Monitor is designed to detect and monitor model drift, alerting the company when inference quality degrades, thus meeting both requirements.

Exact Extract from AWS AI Documents:

From the Amazon SageMaker Developer Guide:

"Amazon SageMaker Model Monitor enables you to monitor machine learning models in production for data drift, model performance degradation, and other quality issues. It can detect drift in feature distributions and inference quality, sending notifications when deviations are detected, allowing you to take corrective actions such as retraining the model."

Detailed Explanation:

Option A: Retrain the model. Monitor model drift by using Amazon SageMaker Clarify.SageMaker Clarify is used for bias detection and explainability, not for monitoring model drift or inference quality in production. This option does not fully meet the requirements.

Option B: Retrain the model. Monitor model drift by using Amazon SageMaker Model Monitor.This is the correct answer. Retraining addresses the current degradation, and SageMaker Model Monitor can detect future drift in inference quality, sending notifications to prevent recurrence, as required.

Option C: Build a new model. Monitor model drift by using Amazon SageMaker Feature Store.SageMaker Feature Store is for managing and sharing features, not for monitoring model drift or inference quality. Building a new model may not be necessary if retraining can address the issue.

Option D: Build a new model. Monitor model drift by using Amazon SageMaker JumpStart.SageMaker JumpStart provides pre-trained models and solutions for quick deployment, but it does not offer specific tools for monitoring model drift or inference quality in production.
