Q404. A solutions architect is troubleshooting an application that runs on Amazon EC2 instances. The EC2 instances runs 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. New when many instances launch at the same time some application components are throttled when the component scan the DynamoDB table.The Auto Scaling group terminates the falling instances and starts new instances unit all applications are running.A solution architect must implement a solution to mitigate the throttling issue in the MOST cost- effective manner.Which solution will these requirements?
A.Doubles the provisioned read capacity of the DynamoDB table. B.Duplicate the DynamoDB tableConfigure the running copy of the application to select at random which table it accesses. C.Set the DynamoDB table to on-demand mode. D.Add DynamoDB Accelerator (DAX) to the table.正确答案D
