DBS-C01 Monitoring and Troubleshooting Practice Question
A developer is troubleshooting an issue where an application using Amazon DynamoDB is receiving occasional 'ThrottlingException' errors. The application uses eventually consistent reads. What is the MOST likely cause of this error?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The read capacity units are set too low for the current traffic pattern
ThrottlingException occurs when the request rate exceeds the provisioned throughput capacity. Option A is incorrect because an incorrect table name would result in a ResourceNotFoundException, not a ThrottlingException. Option C is incorrect because eventually consistent reads consume half the read capacity units compared to strongly consistent reads, making them less likely to cause throttling. Option D is incorrect because network connectivity issues would typically cause timeout or connection errors, not ThrottlingException.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The application is using an incorrect table name
Why it's wrong here
Incorrect table name causes ResourceNotFoundException.
- ✓
The read capacity units are set too low for the current traffic pattern
Why this is correct
Throttling happens when traffic exceeds provisioned capacity.
- ✗
The application is using eventually consistent reads instead of strongly consistent reads
Why it's wrong here
Eventually consistent reads consume less capacity, so they reduce throttling.
- ✗
There is a network connectivity issue between the application and DynamoDB
Why it's wrong here
Network issues cause timeout errors, not throttling.
