AWS Certified Developer Associate DVA-C02 Practice Question

An application running on Amazon ECS makes HTTP API calls to an AWS service. Occasionally the service returns 5xx errors caused by transient throttling.

  • Retry failed requests after a fixed delay between attempts

  • Increase the request payload size with every retry

  • Send multiple parallel requests each time a call fails

  • Implement retries with exponential backoff and jitter
