What is Amazon DynamoDB?

A database service requiring upfront capacity provisioning
An in-memory database for fast data retrieval
A cloud-native database for managing high volumes of records
A service for automating database backups

The correct answer is: A cloud-native database for managing high volumes of records

Amazon DynamoDB is a fully managed, cloud-native NoSQL database service designed to handle high volumes of data with low latency and high performance. It provides seamless scalability, allowing for automatic adjustments to accommodate traffic fluctuations and storage needs, making it well-suited for applications that demand quick and efficient data retrieval. This service is built to manage large and rapidly growing datasets, which makes it an excellent choice for workloads such as real-time analytics, mobile apps, or gaming, where high throughput and quick response times are crucial. DynamoDB automatically spreads the data across servers and replicates it in multiple regions for fault tolerance, ensuring continuous availability and durability. The other options describe database functionalities or offerings that do not align with the primary characteristics or capabilities of DynamoDB. For instance, requiring upfront capacity provisioning is more akin to traditional databases or other managed services requiring specific settings before use, while in-memory databases emphasize speed but do not cover the scale features inherent to DynamoDB. Automated database backups, while important, do not capture the essence of what makes DynamoDB unique as a scalable and high-performance NoSQL database service.
