Question 23 of 100 | ← Chapter 1

A company wants to use AI to protect its applications from threats. The AI solution must check whether IP addresses originate from suspicious sources. Which solution satisfies this requirement?

• A. Build a speech recognition system.
• B. Create a natural language processing (NLP) named entity recognition system.
• C. Develop an anomaly detection system. ✓
• D. Create a fraud prediction system.

Correct Answer: C. Develop an anomaly detection system.

Explanation

This question tests understanding of AI use cases for security. Detecting suspicious IP addresses requires identifying deviations from normal network behavior—i.e., anomalies. Anomaly detection systems are specifically designed to flag statistically unusual or outlier patterns (e.g., IPs from known malicious ranges or exhibiting atypical access frequency). Speech recognition (A) handles audio; NLP named entity recognition (B) extracts entities like names or locations from text—not IP reputation analysis. Fraud prediction (D) may incorporate IP signals but is broader and less directly focused on real-time IP source evaluation. Therefore, option C ('Develop an anomaly detection system') is most appropriate.
