Question

A company needs to store semi-structured transactional data for an application in a database. The database must be serverless. The application writes the data infrequently, but it reads the data frequently. The application must retrieve the data within milliseconds. Which solution will meet these requirements with the LEAST operational overhead?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Store the data in an Amazon DynamoDB table. Configure a DynamoDB Accelerator cache. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. DynamoDB Accelerator (DAX) adds an in-memory cache for microsecond DynamoDB reads. AWS Config tracks resource configuration changes and evaluates compliance.
