In regard to DynamoDB, for which one of the following parameters does Amazon not charge you?
Storage cost
I/O usage within the same Region
Cost per provisioned read units
Cost per provisioned write units
Explanations:
Amazon charges for data storage in DynamoDB based on the total amount of data stored.
There is no charge for data transfer within the same Region in DynamoDB, making this option correct.
Amazon charges based on the provisioned read capacity units in DynamoDB.
