AIF-C01 Applications of Foundation Models Practice Question
Exhibit
Refer to the exhibit. ``` 2024-03-15T10:00:00Z [ERROR] Model invocation failed: AccessDeniedException: User: arn:aws:iam::123456789012:role/BedrockRole is not authorized to perform: bedrock:InvokeModel on resource: arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-v2 ```
A developer encounters the error shown above when using Amazon Bedrock. What is the most likely cause?
⚠ Common exam trap
AWS often tests the distinction between service availability errors and authorization errors, so the trap here is that candidates may confuse a permissions failure with a model unavailability or throttling issue, especially when the error message is generic.
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 IAM role lacks the required permission
The error indicates an access denied or authorization failure when invoking the Amazon Bedrock model. The most likely cause is that the IAM role used by the developer does not have the required permission, such as `bedrock:InvokeModel`, attached to its policy. Without this permission, the API call to Bedrock is rejected regardless of model availability or service status.
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 model is not available in the region
Why it's wrong here
The error does not mention model unavailability; it's an access issue.
- ✓
The IAM role lacks the required permission
Why this is correct
The error explicitly states the role is not authorized for the action.
- ✗
The request is throttled
Why it's wrong here
Throttling would show a ThrottlingException, not AccessDenied.
- ✗
The model is out of service
Why it's wrong here
Out of service would produce a different error, like ModelNotReadyException.
