Google Cloud Professional Cloud Security Engineer Practice Exam

Which two components should be utilized to redact personally identifiable information during ETL processes?

1. Cloud Key Management Service and Cloud Data Loss Prevention

2. BigQuery Data Transfer Service and Cloud Pub/Sub

3. Cloud Security Scanner and Cloud Storage

4. Data Catalog and Cloud Functions

The correct answer is: Cloud Key Management Service and Cloud Data Loss Prevention

Utilizing Cloud Key Management Service and Cloud Data Loss Prevention is an effective approach for redacting personally identifiable information (PII) during ETL (Extract, Transform, Load) processes. Cloud Data Loss Prevention (DLP) is specifically designed to discover, classify, and protect sensitive data. It enables organizations to scan their data for PII and other sensitive types of information, providing features to mask, redact, or otherwise handle this data appropriately in compliance with regulations such as GDPR or HIPAA. During ETL processes, this allows for the automated masking or redacting of sensitive information before the data is processed or moved to its final destination, thereby minimizing the risk of exposure. On the other hand, Cloud Key Management Service provides a way to manage cryptographic keys for your cloud services. While it plays a crucial role in protecting sensitive data through encryption and managing access to these keys, it is not inherently focused on the data discovery and redaction capabilities needed for handling PII during ETL operations. When both of these services are used together, organizations can effectively manage encryption keys while simultaneously utilizing Cloud DLP to discover and redact sensitive information, making option A the most suitable choice for the required task of protecting PII during the ETL processes.
