- A
Implement strict output filtering
Why wrong: Output filtering blocks harmful content but does not limit the LLM's ability to take actions.
- B
Restrict the LLM to read-only or low-risk actions
Limiting the scope of actions reduces the risk of unintended actions.
- C
Apply rate limiting to API calls
Why wrong: Rate limiting controls frequency, not the scope of actions.
- D
Require human-in-the-loop approval for high-risk actions
Human approval adds a safety layer before executing potentially dangerous actions.
- E
Use input validation to sanitize user prompts
Why wrong: Input validation prevents injection but does not control the LLM's actions.
Question 672 of 1,000
AI0-001 AI Security Practice Question
This AI0-001 practice question tests your understanding of ai security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company is deploying an LLM-based system that can execute API calls on behalf of users. Which TWO measures should they implement to prevent excessive agency?
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
✓
Restrict the LLM to read-only or low-risk actions
Option B is correct because restricting the LLM to read-only or low-risk actions directly limits the scope of actions the model can execute, preventing it from performing unauthorized or destructive operations. This is a fundamental principle of least privilege applied to LLM-based systems, ensuring that even if the model is compromised or misused, it cannot escalate its agency to high-impact actions.
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 input/output security measures (like filtering and validation) and agency control measures (like action restrictions and human oversight), leading candidates to confuse defensive coding with permission scoping.
Trap categories for this question
Command / output trap
Output filtering blocks harmful content but does not limit the LLM's ability to take actions.
Detailed technical explanation
How to think about this question
Excessive agency in LLM systems often arises from granting the model broad API access without scoping permissions to specific endpoints or actions. Under the hood, implementing read-only or low-risk actions involves defining a strict allowlist of API methods (e.g., GET requests only, or POST to non-destructive endpoints) and using role-based access control (RBAC) to enforce these boundaries at the middleware layer. In a real-world scenario, a customer support LLM with unrestricted API access could accidentally delete user accounts, whereas restricting it to read-only ticket retrieval prevents such harm.
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.
