#### A Developer is creating a DynamoDB table for storing application logs. The table has 5 write capacity units (WCUs). The Developer needs to configure the read capacity units (RCUs) for the table. Which of the following configurations represents the most efficient use of throughput? #### A Developer is creating a [[_DynamoDB]] table for storing application logs. The table has 5 write capacity units (WCUs). The Developer needs to configure the read capacity units (RCUs) for the table. Which of the following configurations represents the most efficient use of throughput?
