AIF-C01 Fundamentals of Generative AI Practice Question
This AIF-C01 practice question tests your understanding of fundamentals of generative ai. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
Error log from Amazon Bedrock:
{
"error": "AccessDeniedException",
"message": "User: arn:aws:iam::123456789012:role/MyAppRole is not authorized to perform: bedrock:InvokeModel on resource: arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-instant-v1"
}
Refer to the exhibit. A developer receives an error when trying to invoke the Claude Instant model from an application. The application uses the IAM role 'MyAppRole'. Which IAM policy statement should be added to the role to resolve the error?
Exhibit
Error log from Amazon Bedrock:
{
"error": "AccessDeniedException",
"message": "User: arn:aws:iam::123456789012:role/MyAppRole is not authorized to perform: bedrock:InvokeModel on resource: arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-instant-v1"
}
Option C is correct because the error occurs when the application tries to invoke the Claude Instant model via the Bedrock InvokeModel API, and the IAM role 'MyAppRole' lacks the necessary permission. The required action is 'bedrock:InvokeModel', and the resource must be scoped to the specific foundation model ARN, which for Claude Instant in us-east-1 is 'arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-instant-v1'. This grants least-privilege access to invoke exactly that model.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
While this would work, it is overly permissive. Best practice is to scope to the specific model.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the 'InvokeModel' action with 'GetFoundationModel' or choose a wildcard resource ARN, thinking it is sufficient, but AWS specifically tests the need for a precise model ARN to enforce least-privilege access in Bedrock IAM policies.
Detailed technical explanation
How to think about this question
The Bedrock InvokeModel API requires both the 'bedrock:InvokeModel' action and a resource ARN that matches the specific model ID, which follows the pattern 'arn:aws:bedrock:<region>::foundation-model/<model-id>'. The model ID for Claude Instant is 'anthropic.claude-instant-v1', and the region must match the endpoint used by the application. In real-world scenarios, using overly broad resource ARNs (like wildcards) can lead to accidental cost overruns or security risks if the role is compromised, as it would allow invoking any Bedrock model without restriction.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

What is the correct answer to this question?
The correct answer is: {"Effect":"Allow","Action":"bedrock:InvokeModel","Resource":"arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-instant-v1"} — Option C is correct because the error occurs when the application tries to invoke the Claude Instant model via the Bedrock InvokeModel API, and the IAM role 'MyAppRole' lacks the necessary permission. The required action is 'bedrock:InvokeModel', and the resource must be scoped to the specific foundation model ARN, which for Claude Instant in us-east-1 is 'arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-instant-v1'. This grants least-privilege access to invoke exactly that model.
