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.
