The answer is only Claude v2. This is correct because the IAM policy explicitly allows the `bedrock:InvokeModel` action on the exact resource ARN `arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-v2`, which matches only that specific model without any wildcards. On the AWS Certified AI Practitioner AIF-C01 exam, interpreting IAM policies for foundation model access tests your ability to read resource ARNs precisely—a common trap is assuming that a name like "claude" in the ARN implies access to all Claude versions, but IAM policies are literal and deny anything not explicitly allowed. Remember the memory tip: "Exact ARN, exact model"—if the policy lists a full ARN without asterisks, only that single foundation model is accessible, no matter how similar other model names appear.
AIF-C01 Applications of Foundation Models Practice Question
This AIF-C01 practice question tests your understanding of applications of foundation models. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Only Claude v2
The IAM policy explicitly allows the `bedrock:InvokeModel` action only on the resource ARN `arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-v2`. This means the user can invoke only the Claude v2 model. No other models, including other Claude versions or any model with 'claude' in its name, are permitted because the resource ARN is exact and does not use wildcards.
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.
✓
Only Claude v2
Why this is correct
The Allow grants access to Claude v2; the Deny using NotResource denies everything else.

✗
No models
Why it's wrong here
Allow statement grants access to Claude v2.
✗
Claude v2 and any model with a name containing 'claude'
Why it's wrong here
The policy only allows the specific ARN.
✗
Any model in the account
Why it's wrong here
The Deny restricts access to models other than Claude v2.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between an exact resource ARN and a wildcard pattern; candidates mistakenly assume that 'claude' in the model ID implies all Claude models are allowed, but without a wildcard, only the exact model specified is permitted.
Detailed technical explanation
How to think about this question
In AWS IAM, resource-level permissions for Bedrock are evaluated against the exact ARN specified in the policy. The ARN format for foundation models is `arn:aws:bedrock:<region>::foundation-model/<model-id>`. Without a wildcard (`*`) in the resource element, only the exact model ID `anthropic.claude-v2` is allowed. This is a common pattern for least-privilege access control, where each model must be explicitly listed to be accessible.

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.
