AWS Certified Developer - Associate DVA-C02 — Topic 1 Question 443

Question

A developer is creating a database of products. Queries for frequently accessed products must have retrieval times of microseconds. To ensure data consistency, the application cache must be updated whenever products are added, changed, or deleted. Which solution will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Set up an Amazon DynamoDB database and a DynamoDB Accelerator (DAX) cluster. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling.
