- A
Rate limiting on API calls
Why wrong: Rate limiting prevents abuse but does not filter the content of responses.
- B
Input validation and sanitization
Why wrong: Input validation protects against injection but does not control output content.
- C
Audit logging of AI interactions
Why wrong: Audit logs help detect incidents but do not prevent data leakage in real time.
- D
Output filtering with regex and moderation classifiers
Output filtering can detect and redact sensitive information before it reaches the user.
Question 865 of 1,000
AI0-001 AI Security Practice Question
This AI0-001 practice question tests your understanding of ai security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 develops an internal LLM-based tool that queries a vector database containing confidential customer data. Which security measure should be implemented to prevent the LLM from revealing sensitive information in its responses?

Correct answer & explanation
✓
Output filtering with regex and moderation classifiers
Output filtering with regex and moderation classifiers (Option D) is the correct security measure because it directly inspects the LLM's generated responses for sensitive data patterns (e.g., credit card numbers, PII) and blocks or redacts them before delivery. This prevents the LLM from inadvertently leaking confidential customer data retrieved from the vector database, even if the model's training or prompt injection causes it to include such information in its output.
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 controls (like sanitization) and output controls (like filtering), and the trap here is that candidates mistakenly choose input validation (Option B) thinking it prevents data leakage, when in fact the leak occurs in the LLM's output, not the user's input.

Command / output trap
Input validation protects against injection but does not control output content.
Detailed technical explanation
How to think about this question
Output filtering typically uses a combination of regex patterns (e.g., for SSNs, credit card numbers) and machine learning-based moderation classifiers (e.g., toxicity or PII detectors) to scan the LLM's generated text. In a Retrieval-Augmented Generation (RAG) pipeline, the vector database returns relevant chunks of confidential data, and the LLM may inadvertently include verbatim snippets in its response; output filtering acts as a last line of defense. A real-world scenario is a customer support chatbot that retrieves account details from a vector store; without output filtering, the LLM might respond with full credit card numbers instead of masked versions.
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 practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
