The correct answer is B, because AWS recommends that any generative AI initiative begin with use-case clarification, stakeholder alignment, and measurable business objectives. According to the AWS Generative AI Adoption Framework and the AWS Machine Learning Journey guidelines, successful AI projects start with defining specific business outcomes—such as revenue growth, reduced time-to-market, or improved campaign efficiency. Conducting stakeholder interviews ensures the organization identifies the highest-value marketing use cases, such as personalized campaigns or content generation, and sets KPIs to measure revenue impact within the target timeframe. AWS documentation emphasizes avoiding premature model training (option A), which is costly and unnecessary without validated requirements. Implementing a prebuilt assistant (option C) may help operations but does not guarantee alignment with the core revenue objective. Replicating competitor features (option D) may lack strategic alignment. Therefore, refining use cases and measurable goals is the foundational AWS-recommended approach for a targeted revenue-driven generative AI initiative.

Accuracy is the most appropriate metric to measure the performance of an image classification model. It indicates the percentage of correctly classified images out of the total number of images. In the context of classifying plant diseases from images, accuracy will help the company determine how well the model is performing by showing how many images were correctly classified.

Option B (Correct): " Accuracy " : This is the correct answer because accuracy measures the proportion of correct predictions made by the model, which is suitable for evaluating the performance of a classification model.

Option A: " R-squared score " is incorrect as it is used for regression analysis, not classification tasks.

Option C: " Root mean squared error (RMSE) " is incorrect because it is also used for regression tasks to measure prediction errors, not for classification accuracy.

Option D: " Learning rate " is incorrect as it is a hyperparameter for training, not a performance metric.

Clustering is an unsupervised machine learning technique used to group data points based on similarity without requiring labeled data. AWS documentation explains that clustering is commonly used for customer segmentation , where the goal is to discover natural groupings within a dataset.

In this scenario, the dataset is unlabeled and includes behavioral and demographic features. Clustering algorithms analyze patterns and distances between data points to identify distinct customer groups, making this technique ideal for understanding customer segments.

Regression and classification require labeled outputs, and reinforcement learning focuses on sequential decision-making, not grouping. AWS positions clustering as the correct approach for this use case.

Prompt management in Amazon Bedrock enables:

Reuse of standardized prompt templates

Parameterization of prompts with dynamic inputs

Consistent instruction application across use cases

AWS Bedrock guidance describes prompt management as the recommended solution for maintaining reusable prompt templates while injecting product-specific content.

Why the other options are incorrect:

Knowledge Bases (B) provide retrieval, not prompt templating.

Model evaluation (C) assesses quality, not generation.

Cross-region inference (D) addresses availability, not prompt reuse.
