AWS Certified AI Practitioner AIF-C01 Practice Question

AI/ML adds value when patterns must be learned from historical data and can change over time, such as fraud detection, demand forecasting, or personalized recommendations. Calculating sales tax, however, follows fixed percentages defined by law. Because the rules are explicit, infrequently updated, and produce a single deterministic answer, a simple rule-based program is cheaper, easier to maintain, and guarantees the exact outcome required for regulatory compliance. Therefore, an AI/ML approach would be unnecessary and unjustified for this task, whereas the other scenarios inherently involve prediction under uncertainty where ML can provide clear benefits.
