Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 380 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 380
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

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.

Selected Answer: B
B is the best solution. It uses two Amazon SQS queues to ensure that incoming data is not lost and can be processed later in case of failures. The primary queue acts as the initial landing point for data from the API Gateway, and the secondary queue serves as a dead-letter queue, capturing data that could not be processed due to third-party service failures or other issues. This setup maintains data integrity and allows for later processing, effectively improving the solution's resiliency.

Selected Answer: B
https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-configure-dead-letter-queue.html Amazon SQS does not create the dead-letter queue automatically. You must first create the queue before using it as a dead-letter queue. For instructions on creating a queue to use as a dead letter queue, see Create a queue using the Amazon SQS console.

B is right By creating two Amazon SQS queues (primary and secondary) and configuring the secondary queue as a dead-letter queue for the primary queue, you can ensure that failed messages are not lost. The primary queue will receive successful messages and be used as the main processing queue. The secondary queue will serve as a catch-all for failed messages, allowing them to be processed later if the failure is temporary or recoverable.

Option B is most suitable. Eventbridge can not be target for API Gateway

API gateway will need to do http post to post an event to Eventbridge bus and a single eventbus has throttle limits on events/sec. SQS will be a better and more scalable in this case.
