CCAO-FResponsible Use01 / 03

A compliance officer is preparing datasets for use in Claude prompts. Which category of information most clearly demands careful treatment through masking or removal before inclusion?

✕ Not quite— answer B

Option B is correct because government-issued identifiers and financial account numbers tied to individuals represent high-risk personally identifiable information (PII) that requires redaction or anonymization before any use in prompts. Options A, C, and D all consist of information that is already publicly available or non-sensitive in nature, so they do not require the same level of protective handling.

The Claude Singapore Community sponsors community members: pass a short screening and we issue you a free @claudecode.sg partner-network email and a short freelance developer agreement. That address is what lets you register and sit the proctored exam under our partner network.
