    }
  ]
}
```

Refer to the exhibit. An IAM policy is attached to a user. Which models can the user invoke?

⚠ Common exam trap

The AIF-C01 exam 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.

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

✓

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.

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.
