AWS Certified AI Practitioner (AIF-C01) — Question 280

A company deployed a model to production. After 4 months, the model inference quality degraded. The company wants to receive a notification if the model inference quality degrades. The company also wants to ensure that the problem does not happen again.

Which solution will meet these requirements?

Answer options

• A. Retrain the model. Monitor model drift by using Amazon SageMaker Clarify.
• B. Retrain the model. Monitor model drift by using Amazon SageMaker Model Monitor.
• C. Build a new model. Monitor model drift by using Amazon SageMaker Feature Store.
• D. Build a new model. Monitor model drift by using Amazon SageMaker JumpStart.

Correct answer: B

Explanation

Retraining the current model is the appropriate action to address the quality degradation, rather than rebuilding a new model from scratch. Amazon SageMaker Model Monitor is designed specifically to continuously observe model performance in production and send alerts when drift is detected. Other services like Amazon SageMaker Clarify, Feature Store, and JumpStart do not provide continuous model drift monitoring and alerting capabilities.
