AWS Certified AI Practitioner AIF-C01 Practice Question

Zero-shot prompting is used when a user supplies an instruction but no worked examples. The model must rely on its pre-training to perform the requested task. Few-shot prompting adds several labeled examples to guide the model, so it would not meet the requirement of omitting sample reviews. Chain-of-thought prompting asks the model to reveal its reasoning steps and still requires an instruction (and optionally examples). Retrieval-Augmented Generation is not a standalone prompting technique; it enriches prompts with retrieved documents. Therefore, zero-shot prompting is the correct choice for giving only the instruction and no examples.
