PCNSA App-ID and Content-ID Practice Question
Which Content-ID feature can be used to prevent credit card numbers from being sent via webmail applications?
⚠ Common exam trap
It's easy for candidates to confuse Data Filtering with File Blocking, assuming that blocking file attachments is sufficient to prevent data loss, but Data Filtering is specifically designed to inspect and block sensitive text patterns within the body of webmail or other application traffic.

Correct answer & explanation
✓
Data Filtering Profile
Data Filtering Profile is the correct Content-ID feature because it allows you to define custom patterns, such as regular expressions, to match sensitive data like credit card numbers. When a webmail application attempts to send an email containing a matching pattern, the firewall can block or alert on the transaction, preventing data exfiltration.
