Network isolation is a key security feature for SageMaker. It ensures that training and inference jobs run in a VPC and are not accessible from the internet. Per the official SageMaker documentation:

“When you enable network isolation, your model can’t make any outbound network calls. This is useful for security and regulatory compliance when working with sensitive data.”

Zero-shot learning is when the model is asked to perform a task without being given any examples. The prompt simply describes the task and relies on the model’s pre-trained knowledge.

(Reference: Amazon Bedrock Prompt Engineering Guide)

Few-shot learning provides a few examples (shots) in the prompt to show the model how to solve the task before asking it to complete a similar task.

(Reference: Amazon Bedrock Prompt Engineering Guide)

Chain-of-thought reasoning encourages the model to reason step by step and explain its thinking for more complex or logical tasks.

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.

AWS Glue is the correct service for transforming petabytes of unstructured data into a structured format suitable for machine learning tasks.

AWS Glue:

A fully managed extract, transform, and load (ETL) service that makes it easy to prepare and transform unstructured data into a structured format.

Provides a range of tools for cleaning, enriching, and cataloging data, making it ready for data scientists to use in ML models.

Why Option D is Correct:

Data Transformation: AWS Glue can handle large volumes of data and transform unstructured data into structured formats efficiently.

Integrated ML Support: Glue integrates with other AWS services to support ML workflows.

Why Other Options are Incorrect:

A. Amazon Lex: Used for building chatbots, not for data transformation.

B. Amazon Rekognition: Used for image and video analysis, not for data transformation.

C. Amazon Kinesis Data Streams: Handles real-time data streaming, not suitable for batch transformation of large volumes of unstructured data.
