Flashcard Practice AWS Certified AI Practitioner Multiple Choice

A fraud model is trained with a clean field called merchant_risk_score, but in production that field arrives two days late and is blank for new transactions. What is the most likely issue?

Choose the Best Answer

Training-serving skew because the production input data does not match what was available during training. Underfitting because the model has too few parameters for any transaction data. A batch inference problem because all fraud systems must run offline. A labeling problem because inference inputs always require known fraud labels.
