AIP-C01 Testing Validation And Troubleshooting Practice Question
An application deployed on AWS Lambda is receiving 429 Too Many Requests errors when calling Amazon Bedrock. The developer has verified that account-level quotas have not been reached. What is the most likely cause?
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 application is exceeding the tokens-per-minute (TPM) limit for the specific model in that AWS Region.
Model-specific throughput limits or Provisioned Throughput quotas are distinct from account-level service quotas.
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 VPC endpoint policy is blocking traffic to the Bedrock runtime service.
Why it's wrong here
VPC endpoint issues typically result in connectivity timeouts or 403 errors.
- ✓
The application is exceeding the tokens-per-minute (TPM) limit for the specific model in that AWS Region.
Why this is correct
Each model has specific throughput limits that, when exceeded, trigger 429 errors.
- ✗
The Lambda function timeout is set too low for the model response time.
Why it's wrong here
This would result in a 504 Gateway Timeout error.
- ✗
The IAM role is missing the bedrock:InvokeModelWithResponseStream permission.
Why it's wrong here
This would result in a 403 Forbidden error, not a 429.
