Selected Answer: A

Amazon DynamoDB is designed for scale and performance. In most cases, the DynamoDB response times can be measured in single-digit milliseconds. However, there are certain use cases that require response times in microseconds. For these use cases, DynamoDB Accelerator (DAX) delivers fast response times for accessing eventually consistent data. DAX is a DynamoDB-compatible caching service that enables you to benefit from fast in-memory performance for demanding applications. https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DAX.html
