Amazon Bedrock provides large language models (LLMs) that are optimized for natural language understanding and text summarization tasks, making it the best choice for creating concise summaries of user reviews. Time-series forecasting, classification, and image analysis (Rekognition) are not suitable for summarizing textual data. References: AWS Bedrock Documentation.

Amazon Comprehend is the correct service to analyze customer support interactions and identify frequently asked questions and insights.

Amazon Comprehend:

A natural language processing (NLP) service that uses machine learning to uncover insights and relationships in text.

Capable of extracting key phrases, detecting entities, analyzing sentiment, and identifying topics from text data, making it ideal for analyzing customer support interactions.

Why Option B is Correct:

Text Analysis Capabilities: Can process large volumes of text to identify common topics, phrases, and sentiment, providing valuable insights.

Suitable for Customer Support Analysis: Specifically designed to understand the content and meaning of text, which is key for identifying frequently asked questions.

Why Other Options are Incorrect:

A. Amazon Lex: Used for building conversational interfaces, not for text analysis.

C. Amazon Transcribe: Converts speech to text but does not perform text analysis.

D. Amazon Translate: Used for translating text between languages, not for analyzing content.

Generative adversarial networks (GANs) are a type of deep learning model used for generating synthetic data based on existing datasets. GANs consist of two neural networks (a generator and a discriminator) that work together to create realistic data.

Option A (Correct): "Generative adversarial network (GAN)": This is the correct answer because GANs are specifically designed for generating synthetic data that closely resembles the real data they are trained on.

Option B: "XGBoost" is a gradient boosting algorithm for classification and regression tasks, not for generating synthetic data.

Option C: "Residual neural network" is primarily used for improving the performance of deep networks, not for generating synthetic data.

Option D: "WaveNet" is a model architecture designed for generating raw audio waveforms, not synthetic data in general.

AWS AI Practitioner References:

GANs on AWS for Synthetic Data Generation: AWS supports the use of GANs for creating synthetic datasets, which can be crucial for applications like training machine learning models in environments where real data is scarce or sensitive.

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.
