Amazon Web Services AIF-C01 Questions Answers

The verified selections are Few-shot prompting, Chain-of-thought prompting, and Zero-shot prompting. The first description matches few-shot prompting because AWS describes few-shot prompting as a technique that includes example outputs or demonstrations in the initial prompt so the model can understand the expected pattern before generating a response. The phrase “provide a small number of examples” is the key indicator. A few-shot prompt gives the model limited examples of the desired task, format, or reasoning style, and the model uses those examples as context for the next output.

The second description matches chain-of-thought prompting. AWS describes chain-of-thought prompting as a technique that helps a model solve a problem by following a series of intermediate reasoning steps before reaching the final answer. The wording “break down the step-by-step process” directly points to chain-of-thought prompting. This method is commonly associated with reasoning, arithmetic, logic, planning, and multi-step problem solving because the prompt encourages the model to work through intermediate steps rather than immediately outputting a final answer.

The third description matches zero-shot prompting because AWS describes zero-shot prompting as asking the model to perform a task without providing examples in the prompt. The model relies only on the instruction and its pre-trained knowledge. The phrase “without providing examples” is the decisive clue.

Role-based prompting is not used here because none of the descriptions asks the model to act as a specific persona, job role, or domain expert, such as “Act as a financial analyst” or “You are a security engineer.” Single-shot prompting is also not used because the first description says a “small number of examples,” which indicates few-shot prompting, not exactly one example. Therefore, the three correct hotspot mappings are Few-shot prompting, Chain-of-thought prompting, and Zero-shot prompting.

The verified answer is A. Balance class representation in the dataset. The requirement is to train an AI model on data that reflects the diversity of a global customer base. In AWS responsible AI guidance, dataset quality is directly connected to fairness, bias reduction, and model behavior across different user groups. AWS identifies dataset characteristics such as inclusivity, diversity, curated data sources, and balanced datasets as part of responsible AI knowledge for AI practitioners. This directly supports the need for a dataset that represents diverse users instead of overrepresenting one group and underrepresenting another.

AWS also explains that bias can result from imbalances in data or from differences in model performance across groups. Amazon SageMaker Clarify is designed to help detect and mitigate potential bias during data preparation, after training, and in deployed models by examining specified attributes. This supports the principle that the training dataset should be examined and balanced before model training so that the model does not preferentially learn patterns from majority groups while performing poorly for minority groups.

Option B is incorrect because using a regional dataset, even if complete, does not satisfy a global diversity requirement. A complete regional dataset may still exclude languages, demographics, cultural contexts, behaviors, and usage patterns from other regions. Option C is incorrect because oversampling majority class data worsens imbalance. It increases the dominance of already overrepresented groups and can amplify biased model behavior. Option D is also incorrect because dropping minority class records removes exactly the user groups that must be represented for a global customer base.

AWS SageMaker Clarify documentation specifically describes class imbalance bias as a situation where one facet has fewer training samples than another. AWS notes that models may preferentially fit larger facets at the expense of smaller facets, leading to higher training error for underrepresented groups. Therefore, balancing class representation is the best action because it improves dataset representativeness and supports responsible AI fairness for a diverse global user base.

The correct answer is B because Amazon Augmented AI (Amazon A2I) allows developers to integrate human review workflows into ML systems. It supports defining confidence thresholds, such that only low-confidence predictions are sent to human reviewers.

From AWS documentation:

" Amazon A2I provides built-in human review workflows for ML predictions. You can configure confidence thresholds to determine when human review is triggered, enabling continual adjustment based on accuracy needs. "

This supports use cases where business decisions (like financial approvals) require manual oversight for edge cases.

Explanation of other options:

A. Amazon Personalize is used for recommendation systems, not human review.

C. Amazon Inspector is for security assessment and vulnerability scanning.

D. AWS Audit Manager is used for compliance audits, not ML prediction reviews.

Amazon SageMaker Canvas is a visual, no-code machine learning interface that allows users to build machine learning models without having any coding experience or knowledge of machine learning algorithms. It enables users to analyze internal and external data, and make predictions using a guided interface.

Option D (Correct): " Import the data into Amazon SageMaker Canvas. Build ML models and demand forecast predictions by selecting the values in the data from SageMaker Canvas " : This is the correct answer because SageMaker Canvas is designed for users without coding experience, providing a visual interface to build predictive models with ease.

Option A: " Store the data in Amazon S3 and use SageMaker built-in algorithms " is incorrect because it requires coding knowledge to interact with SageMaker ' s built-in algorithms.

Option B: " Import the data into Amazon SageMaker Data Wrangler " is incorrect. Data Wrangler is primarily for data preparation and not directly focused on creating ML models without coding.

Option C: " Use Amazon Personalize Trending-Now recipe " is incorrect as Amazon Personalize is for building recommendation systems, not for general demand forecasting.
