AI0-001 AI Security Practice Question
A developer wants to secure an AI API service. Which practice is MOST effective for preventing unauthorized access to the model?
⚠ Common exam trap
The AI0-001 exam 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.

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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using a larger context window
Why it's wrong here
Larger context window does not affect authorization.
- ✓
Enforcing least-privilege API access with proper key management
Why this is correct
Correct. Least-privilege and key management are foundational access controls.
- ✗
Enabling response logging
Why it's wrong here
Logging is detective, not preventive.
- ✗
Implementing rate limiting
Why it's wrong here
Rate limiting throttles usage but does not prevent unauthorized access.
