Show answer and explanation

Correct answer: A

Explanation

Amazon S3 is the best choice for building a data lake because of its ability to store and retrieve structured, semi-structured, and unstructured data at scale. It is cost-effective, offers high durability, and integrates seamlessly with AWS analytics and machine learning services, making it the ideal storage platform for such use cases.

  • A. Correct.

    Amazon S3 is an object storage service that is cost-effective, highly scalable, and supports storing structured, semi-structured, and unstructured data. It integrates well with AWS analytics services like AWS Glue, Amazon Athena, and Amazon EMR, making it an ideal choice for a data lake solution.

  • B. Incorrect.

    Amazon RDS is a relational database service optimized for structured data and transactional workloads. It is not designed for storing unstructured data or building a data lake.

  • C. Incorrect.

    Amazon EBS is a block storage service used for EC2 instances. It is not suitable for building a scalable data lake or for analyzing large datasets.

  • D. Incorrect.

    Amazon DynamoDB is a NoSQL database service designed for highly available and low-latency key-value or document-based workloads. It is not a storage platform for building a data lake or storing diverse data formats.
