Question

A company deployed a serverless application that uses Amazon DynamoDB as a database layer. The application has experienced a large increase in users. The company wants to improve database response time from milliseconds to microseconds and to cache requests to the database. Which solution will meet these requirements with the LEAST operational overhead?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Use DynamoDB Accelerator (DAX). 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.
