- A
Disable API keys and rely on IP whitelisting only
Why wrong: IP whitelisting is not sufficient for granular access control and does not prevent data leakage.
- B
Use a single shared API key for all services
Why wrong: Shared keys reduce auditability and increase breach impact.
- C
Grant all API keys full access to simplify management
Why wrong: Full access violates least privilege and increases risk of data leakage.
- D
Implement least-privilege API access with scoped permissions
Least privilege limits data exposure by restricting each key to necessary actions and data.

AI0-001 AI Security Practice Question
This AI0-001 practice question tests your understanding of ai security. 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.
A developer is deploying an AI service API. To protect against data leakage through API responses, which access control principle should be applied to API keys?
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
✓
Implement least-privilege API access with scoped permissions
Option D is correct because the least-privilege principle ensures that each API key is scoped to only the specific permissions required for its intended function, such as read-only access to a single endpoint. This minimizes the blast radius in case the key is compromised, preventing unauthorized access to other services or data. In AI service deployments, scoped permissions are often enforced via OAuth 2.0 scopes or IAM roles tied to the API key.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that simplifying management (Option C) or using IP whitelisting (Option A) is sufficient for security, but the trap is that these approaches ignore the fundamental need for granular access control to prevent data leakage in multi-tenant AI API environments.
Detailed technical explanation
How to think about this question
Under the hood, scoped permissions are typically implemented via API key metadata that maps to a set of allowed actions (e.g., GET /v1/models, POST /v1/completions) and resource paths, often validated by a policy engine like AWS IAM or Azure RBAC. A real-world scenario is an AI chatbot service where a key for user-facing queries should have read-only access to the inference endpoint, while a key for model training needs write access to the training dataset; mixing these scopes could leak training data through inference responses. The OAuth 2.0 framework's 'scope' parameter is a common standard for this, and misconfiguring scopes is a frequent source of data breaches.
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 junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
