PCNSA App-ID and Content-ID Practice Question
Which Content-ID feature can be used to prevent data loss by blocking specific patterns in traffic?
⚠ Common exam trap

Correct answer & explanation
✓
Data Filtering
Data Filtering is the correct answer because it is the Content-ID feature specifically designed to inspect application-layer traffic for predefined patterns, such as credit card numbers, social security numbers, or custom regex patterns, and block or alert on matches to prevent data loss. Unlike URL Filtering or File Blocking, Data Filtering operates on the content within allowed traffic, making it the direct tool for data loss prevention (DLP) based on pattern matching.
