A solutions architect is troubleshooting an application that runs on Amazon EC2 instances. The EC2 instances run in an Auto Scaling group. The application needs to access user data in an Amazon DynamoDB table that has fixed provisioned capacity.

To match the increased workload, the solutions architect recently doubled the maximum size of the Auto Scaling group. Now, when many instances launch at the same time, some application components are throttled when the components scan the DynamoDB table. The Auto Scaling group terminates the failing instances and starts new instances until all applications are running A solutions architect must implement a solution to mitigate the throttling issue in the MOST cost-effective manner Which solution will meet these requirements?
