- A
Queries that include SQL injection attempts
Why wrong: SQL injection targets databases, not model extraction.
- B
Queries that repeatedly ask for the same prediction
Why wrong: Repeated identical queries are more indicative of a denial-of-service or probing, not extraction.
- C
A large number of queries from a single IP address over a short period
High query volume is typical for extraction.
- D
Queries with special characters attempting to reveal system prompts
Why wrong: This suggests prompt injection or jailbreaking, not extraction.
- E
Queries covering a wide range of diverse inputs
Diverse inputs help the attacker map the model's decision boundary.
Question 143 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 data scientist suspects a model extraction attack on their deployed classifier. Which TWO indicators are MOST consistent with such an attack? (Select two.)
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
✓
A large number of queries from a single IP address over a short period
Option C is correct because a model extraction attack involves an adversary sending a large volume of queries from a single IP address in a short period to systematically probe the decision boundary of the classifier. This behavior is consistent with the attacker attempting to reconstruct a surrogate model by collecting enough input-output pairs to approximate the target model's function.
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 model extraction (which requires diverse inputs to map the decision boundary) and denial-of-service or brute-force attacks (which involve repeated identical queries), so candidates mistakenly select Option B thinking any high query volume indicates extraction.
Detailed technical explanation
How to think about this question
Model extraction attacks exploit the fact that a classifier's decision boundary can be approximated by querying it with a carefully crafted set of inputs, often using techniques like Jacobian-based dataset augmentation or active learning. In practice, an attacker might use a single IP to send thousands of queries per second, leveraging the model's API to collect labeled examples that are then used to train a substitute model, which can later be used for further attacks like adversarial example generation.
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.
