 Sentiment analysis → Text data

 Traffic sign recognition → Image data

 Customer demographics & purchase history → Tabular data

 Stock price forecasting → Time series data

 AWS classifies NLP tasks like sentiment analysis under text data

 Computer vision tasks such as object and sign recognition use image data

 Structured rows and columns (demographics, transactions) are tabular data

 Sequential data indexed by time (prices, metrics) is time series data

The correct answers are A and E because both directly align with AWS best practices for securing generative AI services and data privacy in enterprise applications.

From the AWS Amazon Q Business documentation:

" AWS Key Management Service (KMS) integrates with Amazon Q Business to encrypt sensitive data at rest. You can use customer-managed KMS keys to meet compliance requirements. "

And:

" You must configure IAM access controls to manage which users and applications can access Amazon Q Business indexes, ensuring that only authorized users can retrieve information. "

Explanation of other options:

B. Cross-account access is not a common requirement for internal enterprise use of Amazon Q Business unless explicitly sharing data across organizations. It’s not a requirement for securing access.

C. Amazon Inspector is a vulnerability management tool for EC2 and containers. It is unrelated to Amazon Q authentication or security.

D. Allowing public access would violate security and privacy principles and directly contradict the stated requirement.

The scenario where a student copies content from generative AI to write essays represents the challenge of plagiarism in responsible AI use.

Plagiarism:

Occurs when someone uses content generated by AI (or any source) without proper attribution, claiming it as their own.

This is a key challenge with generative AI models, which can produce human-like text that might be misused for academic or other purposes.

Why Option C is Correct:

Represents Unauthorized Use: Copying content directly from AI without attribution is a clear case of plagiarism.

Ethical Concern: Highlights the ethical considerations around using AI-generated content responsibly.

Why Other Options are Incorrect:

A. Toxicity: Refers to harmful or offensive content generation, not content copying.

B. Hallucinations: When AI generates incorrect or nonsensical information, not plagiarism.

D. Privacy: Involves the misuse or exposure of personal information, not copying content.

The correct answer is A because each foundation model on Amazon Bedrock (e.g., Claude, Titan, Mistral, Meta Llama) has a different maximum token limit, which defines the maximum number of tokens the model can accept in the prompt and generate in the response.

From AWS documentation:

" Each model in Amazon Bedrock has its own maximum token limit. Prompts exceeding the limit must be truncated or adjusted depending on the selected model. "

Explanation of other options:

B. On-demand inference support is a platform feature that is uniformly supported across models on Bedrock.

C. All Bedrock LLMs support randomness control through temperature and top-p parameters.

D. Amazon Bedrock Guardrails are designed to work across supported models, though specific behaviors may vary slightly.
