AWS Certified Developer Associate DVA-C02 Practice Question
Your application, which makes frequent calls to AWS services using the AWS SDK, has started to experience intermittent failures. Upon inspecting the logs, you observe several instances of an exception being thrown, indicating that the service thinks the request is being sent too quickly. Which of the following exceptions would BEST describe the situation described and requires implementing proper error handling strategies to mitigate the issue?
The ProvisionedThroughputExceededException is the correct answer because it indicates that the application has exceeded the provisioned throughput for a resource and additional requests are being throttled. When an application exceeds the number of requests per second for a given resource, AWS services can throw this exception. Implementing retry logic with exponential backoff or increasing provisioned capacity can help resolve this issue. The other options given do not directly relate to the symptoms described, which involve a service perceiving requests as being sent too quickly.
