Correct answer & explanation
✓
Amazon Augmented AI (A2I)
Amazon Augmented AI (A2I) enables human review of predictions when the model confidence is low or when the decision is high-risk. SageMaker Ground Truth is for data labeling, not for production review. Bedrock is for foundation models. Lambda is compute, not a review service.
