AWS Certified Solutions Architect - Professional SAP-C02 — Topic 1 Question 380

Question

A company has a solution that analyzes weather data from thousands of weather stations. The weather stations send the data over an Amazon API Gateway REST API that has an AWS Lambda function integration. The Lambda function calls a third-party service for data pre-processing. The third-party service gets overloaded and fails the pre-processing, causing a loss of data. A solutions architect must improve the resiliency of the solution. The solutions architect must ensure that no data is lost and that data can be processed later if failures occur. What should the solutions architect do to meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Create two Amazon Simple Queue Service (Amazon SQS) queues: a primary queue and a secondary queue. Configure the secondary queue as the dead-letter queue for the primary queue. Update the API to use a new integration... AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon SQS is a fully managed message queue that decouples components and absorbs traffic spikes. AWS Config tracks resource configuration changes and evaluates compliance. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
