AIF-C01 Applications of Foundation Models Practice Question
This AIF-C01 practice question tests your understanding of applications of foundation models. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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
Refer to the exhibit.
{
"error": {
"message": "Access denied. Please ensure you have the correct permissions to access the requested model.",
"type": "AccessDeniedException"
}
}
(This error is returned when calling the InvokeModel API in Amazon Bedrock with model ID 'anthropic.claude-v2'.)
A developer is trying to invoke the Claude v2 model in Amazon Bedrock from a Lambda function. The Lambda function's IAM role has the following policy attached:
When the Lambda function runs, it receives the error shown in the exhibit. Which additional step is most likely needed to resolve this issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Exhibit

{
"error": {
"message": "Access denied. Please ensure you have the correct permissions to access the requested model.",
"type": "AccessDeniedException"
}
}
(This error is returned when calling the InvokeModel API in Amazon Bedrock with model ID 'anthropic.claude-v2'.)
A
Change the AWS region to one where Claude v2 is available.
Why wrong: Region availability is not the issue; the error is about access permissions.
B
Use a different model ID such as 'anthropic.claude-v1'.
Why wrong: Without model access, any model ID will produce the same error.
C
Request access to the Anthropic Claude model through the Amazon Bedrock console.
Model access must be explicitly granted per model even with IAM permissions.
D
Add a condition to the IAM policy to specify the model ARN.
Why wrong: The policy already allows all models; access is denied because the model is not enabled for the account.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Request access to the Anthropic Claude model through the Amazon Bedrock console.
Option C is correct because Amazon Bedrock requires explicit user access approval for third-party foundation models like Anthropic Claude before they can be invoked. Even with a valid IAM policy allowing bedrock:InvokeModel on all resources, the model itself must be granted access via the Bedrock console's 'Model access' section. Without this step, the API returns an access denied error regardless of IAM permissions.
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.
✗

Use a different model ID such as 'anthropic.claude-v1'.
Why it's wrong here
Without model access, any model ID will produce the same error.
✓
Request access to the Anthropic Claude model through the Amazon Bedrock console.
Why this is correct
Model access must be explicitly granted per model even with IAM permissions.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume a wildcard IAM policy (Resource: '*') grants full access, but Bedrock requires an additional explicit model access approval that is independent of IAM, causing them to incorrectly focus on policy or region changes.
Detailed technical explanation
How to think about this question
Amazon Bedrock enforces a two-layer authorization model: IAM policies control API-level permissions, while a separate 'model access' setting in the Bedrock console controls which foundation models a user or account can invoke. This model access must be explicitly enabled per model (e.g., Anthropic Claude v2) and can take a few minutes to propagate. In real-world scenarios, developers often overlook this step after setting up IAM roles, leading to confusing 'AccessDeniedException' errors even with permissive policies.
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.
