GCP Professional Cloud Security Engineer Practice Question

Your security team must scan several terabytes of log files stored in Cloud Storage with Sensitive Data Protection (SDP). The files may contain U.S. Social Security numbers (formatted as "123-45-6789") and an internal customer identifier that always starts with "CUST-" followed by exactly 10 digits (for example, "CUST-0123456789"). The team wants to minimize configuration effort while keeping false positives low. Which detection strategy best meets these requirements?

  • Use the built-in US_SOCIAL_SECURITY_NUMBER infoType and create a custom regular-expression infoType named ACME_CUSTOMER_ID that matches the pattern "CUST-\d{10}" (optionally adding a hotword rule that looks for the string "CUST-").

  • Use the built-in CREDIT_CARD_NUMBER infoType for SSNs and create a custom dictionary detector that lists every known customer ID.

  • Rely on the built-in PERSON_NAME infoType for SSNs and the built-in PHONE_NUMBER infoType for the customer ID because both contain digits and delimiters.

  • Create custom regular-expression infoTypes for both SSNs and the customer ID so you can fully control pattern matching.
