AI0-001 AI Implementation and Operations Practice Question
Exhibit
Refer to the exhibit.
```json
{
"model_policy": {
"model": "fraud-detection-v3",
"allowed_roles": ["data_scientist", "ml_engineer"],
"denied_roles": ["intern"],
"endpoint": "/api/v1/predict"
}
}
```Refer to the exhibit. A team created an access policy for a fraud detection model endpoint. An intern reports being unable to access the model for testing. Reviewing the policy, what is the most likely cause?
⚠ Common exam trap
CompTIA often tests the explicit deny override principle, where candidates mistakenly think that listing a role in allowed roles guarantees access, ignoring that an explicit deny in the same policy will block it.
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 intern's role is explicitly denied in the policy
The exhibit shows an explicit `Deny` effect for the intern's role in the policy. In AWS IAM (or similar cloud provider) access policies, an explicit deny overrides any allow, so even if the intern's role is listed in allowed roles, the explicit deny will block access. This is a fundamental principle of IAM policy evaluation logic.
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 intern's role is not included in the allowed roles
Why it's wrong here
That alone wouldn't cause denial if not explicitly denied.
- ✗
The policy JSON has a syntax error
Why it's wrong here
The JSON is valid.
- ✗
The endpoint path is incorrect
Why it's wrong here
Exhibit shows correct path.
- ✓
The intern's role is explicitly denied in the policy
Why this is correct
Denied roles override any allowed list.
