Question 13
Domain 1: Fundamentals of AI and MLA bank wants to reduce credit-card fraud losses. Which AI application directly addresses this business goal?
Correct answer: B
Explanation
Real-time fraud detection is a classic anomaly-detection ML use case. The other options are valid AI applications but address different business problems (cross-sell, support, data extraction).
Why each option is right or wrong
A. A recommendation engine suggesting credit-card products to customers
Product recommendation targets average order value increase, not fraud-loss prevention.
B. An anomaly-detection model that flags transactions whose patterns deviate from a cardholder's baseline
C. A chatbot that answers customer service FAQs
Chatbots handle customer service FAQs and support interactions, not transaction fraud detection.
D. An OCR pipeline that extracts text from scanned receipts
OCR extracts text from scanned documents, not behavioral anomalies in card transactions.
