Answer options

• A. Amazon SageMaker Ground Truth
• B. Amazon OpenSearch Service
• C. Amazon Transcribe
• D. Amazon Textract

Correct answer: B

Explanation

Amazon OpenSearch Service includes vector database capabilities, allowing it to store and search high-dimensional vector embeddings utilized by foundation models and Retrieval Augmented Generation (RAG). The other options, such as Amazon SageMaker Ground Truth for data labeling, Amazon Transcribe for speech-to-text, and Amazon Textract for document text extraction, do not offer vector database functionality.
