Google Cloud Professional Cloud Architect — Question 88

Your customer support tool logs all email and chat conversations to Cloud Bigtable for retention and analysis. What is the recommended approach for sanitizing this data of personally identifiable information or payment card information before initial storage?

Answer options

• A. Hash all data using SHA256
• B. Encrypt all data using elliptic curve cryptography
• C. De-identify the data with the Cloud Data Loss Prevention API
• D. Use regular expressions to find and redact phone numbers, email addresses, and credit card numbers

Correct answer: C

Explanation

The correct answer is C, as the Cloud Data Loss Prevention API is specifically designed to identify and de-identify sensitive data effectively. Options A and B focus on securing data rather than sanitizing it, and option D, while it could help, is less comprehensive and may not catch all variations of sensitive information.
