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?

A. Create an Amazon Simple Queue Service (Amazon SQS) queue. configure the queue as the dead-letter queue for the API.

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 to the primary queue. configure the Lambda function as the invocation target for the primary queue.

C. Create two Amazon EventBridge event buses: a primary event bus and a secondary event bus. Update the API to use a new integration to the primary event bus. configure an EventBridge rule to react to all events on the primary event bus. Specify the Lambda function as the target of the rule. configure the secondary event bus as the failure destination for the Lambda function.

D. Create a custom Amazon EventBridge event bus. configure the event bus as the failure destination for the Lambda function.
