AWS Certified AI Practitioner AIF-C01 Updated Exam

To comply with multiple regulatory frameworks, the company must ensure data protection and threat detection. Data protection involves safeguarding sensitive customer information, while threat detection identifies and mitigates security threats to the application.

Option C (Correct): "Data protection":This is correct because data protection is critical for compliance with privacy and security regulations.

Option B (Correct): "Threat detection":This is correct because detecting and mitigating threats is essential to maintaining the security posture required for regulatory compliance.

Option A:"Auto scaling inference endpoints" is incorrect because auto-scaling does not directly relate to regulatory compliance.

Option D:"Cost optimization" is incorrect because it is focused on managing expenses, not compliance.

Option E:"Loosely coupled microservices" is incorrect because this architectural approach does not directly address compliance requirements.

AWS AI Practitioner References:

AWS Compliance Capabilities:AWS offers services and tools, such as data protection and threat detection, to help companies meet regulatory requirements for security and privacy.

AWS CloudTrail is a service that enables governance, compliance, and operational and risk auditing of your AWS account. It tracks API calls and identifies unauthorized access attempts to AWS resources, including Amazon Bedrock.

AWS CloudTrail:

Provides detailed logs of all API calls made within an AWS account, including those to Amazon Bedrock.

Can identify unauthorized access attempts by logging and monitoring the API calls, which helps in setting appropriate IAM policies and roles.

Why Option B is Correct:

Monitoring and Security:CloudTrail logs all access requests and helps detect unauthorized access attempts.

Auditing and Compliance:The logs can be used to audit user activity and enforce security measures.

Why Other Options are Incorrect:

A. AWS Audit Manager:Used for automating audit preparation, not for tracking real-time unauthorized access attempts.

C. Amazon Fraud Detector:Designed to detect fraudulent online activities, not unauthorized access to AWS services.

D. AWS Trusted Advisor:Provides best practice recommendations for AWS resources, not access monitoring.

Thus,Bis the correct answer for identifying unauthorized users attempting to access Amazon Bedrock.

Sampling bias is the correct type of bias affecting the model output when it disproportionately flags people from a specific ethnic group.

Sampling Bias:

Occurs when the training data is not representative of the broader population, leading to skewed model outputs.

In this case, if the model disproportionately flags people from a specific ethnic group, it likely indicates that the training data was not adequately balanced or representative.

Why Option B is Correct:

Reflects Data Imbalance:A biased sample in the training data could result in unfair outcomes, such as disproportionately flagging a particular group.

Common Issue in ML Models:Sampling bias is a known problem that can lead to unfair or inaccurate model predictions.

Why Other Options are Incorrect:

A. Measurement bias:Involves errors in data collection or measurement, not sampling.

C. Observer bias:Refers to bias introduced by researchers or data collectors, not the model's output.

D. Confirmation bias:Involves favoring information that confirms existing beliefs, not relevant to model output bias.

A confusion matrix is the correct metric for evaluating the performance of a classification model, such as the deep learning model built to classify types of materials in images.

Confusion Matrix:

It is a table used to describe the performance of a classification model by comparing the actual and predicted classifications.

Provides detailed insights into the model’s performance, including true positives, true negatives, false positives, and false negatives.

Why Option A is Correct:

Performance Measurement:Helps measure various performance metrics like accuracy, precision, recall, and F1-score, which are critical for evaluating a classification model.

Comprehensive Evaluation:Allows for a thorough analysis of where the model is making errors and the types of errors being made.

Why Other Options are Incorrect:

B. Correlation matrix:Used to identify relationships between variables, not for evaluating classification performance.

C. R2 score:Used for regression models, not classification.

D. Mean squared error (MSE):Also a metric for regression, measuring the average of the squares of the errors.
