AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 567

Question

A solutions architect is designing a workload that will store hourly energy consumption by business tenants in a building. The sensors will feed a database through HTTP requests that will add up usage for each tenant. The solutions architect must use managed services when possible. The workload will receive more features in the future as the solutions architect adds independent components. Which solution will meet these requirements with the LEAST operational overhead?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Use Amazon API Gateway with AWS Lambda functions to receive the data from the sensors, process the data, and store the data in an Amazon DynamoDB table. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon DynamoDB is a fully managed, serverless NoSQL database with single-digit millisecond latency and automatic scaling. Amazon API Gateway is a fully managed front door for creating and securing APIs at scale.
