Q: 5
A developer is receiving an intermittent ProvisionedThroughputExceededException error from an
application that is based on Amazon DynamoDB. According to the Amazon CloudWatch metrics for
the table, the application is not exceeding the provisioned throughput. What could be the cause of
the issue?

D , but I think it's a trap-sort key doesn't impact partition throughput like hash key does. B is probably correct here based on exam reports, open to corrections.
B tbh, seen similar questions in practice exams and the AWS docs are clear about hot partitions on hash keys.
C
It’s B since the app can overload a single hash key, creating a hot partition even when total throughput looks fine. Pretty sure this fits what’s seen in exam reports too. Correct me if I’m missing anything.
