- A
Using a larger context window
Why wrong: Larger context window does not affect authorization.
- B
Enforcing least-privilege API access with proper key management
Correct. Least-privilege and key management are foundational access controls.
- C
Enabling response logging
Why wrong: Logging is detective, not preventive.
- D
Implementing rate limiting
Why wrong: Rate limiting throttles usage but does not prevent unauthorized access.

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 wants to secure an AI API service. Which practice is MOST effective for preventing unauthorized access to the model?

Correct answer & explanation
✓
Enforcing least-privilege API access with proper key management
Enforcing least-privilege API access with proper key management is the most effective practice because it ensures that each API key or token has only the minimum permissions necessary for its intended function, reducing the attack surface. Proper key management includes rotating keys, using scoped access tokens (e.g., OAuth 2.0 scopes), and storing keys securely (e.g., using a secrets manager like AWS Secrets Manager or HashiCorp Vault). This directly prevents unauthorized access by limiting what a compromised or misused key can do, unlike other options that address secondary concerns.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between preventive and detective controls, and the trap here is that candidates confuse rate limiting (a throttling mechanism) with access control, thinking it prevents unauthorized access when it only limits the frequency of requests.
Detailed technical explanation
How to think about this question
Under the hood, least-privilege API access is typically enforced via IAM policies (e.g., AWS IAM, Azure RBAC) that bind API keys to specific actions (e.g., 'model:invoke' but not 'model:update') and resources (e.g., a specific model version). A subtle behavior is that API keys should be scoped to the minimum required endpoints and have expiration times; for example, a key used for inference should not have permissions to list or delete models. In a real-world scenario, a misconfigured key with full admin access could allow an attacker to exfiltrate the entire model or modify its behavior, whereas a least-privilege key would only allow inference on a single endpoint.
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.
