Multiple Choice

However, write capacity units to the primary table are available and not fully consumed. Why is the table being throttled?

• A) The GSI write capacity units are underprovisioned
• B) There are not enough read capacity units on the primary table
• C) Amazon DynamoDB Streams is not enabled on the table
• D) A large write operation is being performed against another table
