AWS Certified Developer – Associate — Question 173

A company hosts a web application that writes to an Amazon DynamoDB table. Application users frequently observe and report errors. The development team examines Amazon CloudWatch logs and frequently sees the following error:

400 Bad Request ProvisionedThroughputExceededException

What is the cause of this error?

Answer options

• A. The application does not have the required permissions for the DynamoDB table.
• B. The item that the application is placing on the table exceeds the item size limit.
• C. The development team has not allocated enough space for the table and its indexes.
• D. The development team has not allocated enough write capacity units (WCU) for the table and Its indexes.

Correct answer: D

Explanation

The correct answer is D because the ProvisionedThroughputExceededException error indicates that the write operations are exceeding the allocated write capacity units (WCU) for the table. Options A and B are incorrect because they do not relate to capacity issues, and option C is also incorrect as it specifically pertains to the allocation of space rather than write capacity.
