Amazon Web Services AIF-C01 Dumps Questions Answers

The correct answer is C because BERTScore is a commonly used metric to evaluate the semantic similarity between generated text (like summaries) and reference text. It uses contextual embeddings from BERT to compare generated and reference sentences, making it highly suitable for evaluating generative tasks like summarization.

From AWS documentation:

" Amazon Bedrock supports BERTScore for evaluating generative text tasks, such as summarization or translation, by comparing the semantic similarity between the output and a reference. "

Explanation of other options:

A. AUC is used for binary classification models, not generative text.

B. F1 score is also used for classification problems (precision/recall balance).

D. Real World Knowledge (RWK) score is not a standard or supported evaluation metric in Amazon Bedrock.

The correct answer is B – Enable model invocation logging in Amazon Bedrock. AWS Bedrock provides native functionality to log all model invocations, including input prompts, parameters, and generated outputs, to Amazon CloudWatch Logs or S3. According to AWS documentation, this feature helps developers monitor model usage, analyze errors, and audit for compliance. Unlike CloudTrail or Audit Manager, which record API events and compliance data respectively, invocation logging captures real inference transactions. EventBridge is used for event routing, not persistent log storage. Bedrock’s logging feature ensures complete traceability for debugging, usage analytics, and governance in accordance with Responsible AI principles.

Creating effective prompts is the best solution to ensure that the content generated by a pre-trained generative AI model aligns with the company ' s brand voice and messaging requirements.

Effective Prompt Engineering:

Involves crafting prompts that clearly outline the desired tone, style, and content guidelines for the model.

By providing explicit instructions in the prompts, the company can guide the AI to generate content that matches the brand’s voice and messaging.

Why Option C is Correct:

Guides Model Output: Ensures the generated content adheres to specific brand guidelines by shaping the model ' s response through the prompt.

Flexible and Cost-effective: Does not require retraining or modifying the model, which is more resource-efficient.

Why Other Options are Incorrect:

A. Optimize the model ' s architecture and hyperparameters: Improves model performance but does not specifically address alignment with brand voice.

B. Increase model complexity: Adding more layers may not directly help with content alignment.

D. Pre-training a new model: Is a costly and time-consuming process that is unnecessary if the goal is content alignment.
