How does Google Cloud ensure that customer data remains secure and (Digital Leader)

Correct answer: C) By auditing platform privacy practices against industry standards.
Here's why:

A) Aggregating training data for customers within each industry is not directly related to ensuring the security and privacy of customer data when at rest. It pertains more to data processing and analytics.

B) Automatically locking files containing suspicious code is a security measure to prevent malicious activities, but it does not directly address the security and privacy of customer data when at rest.

C) Auditing platform privacy practices against industry standards involves regular assessments and reviews of Google Cloud's privacy practices to ensure compliance with relevant regulations and standards. This includes measures to protect customer data when at rest, such as encryption, access controls, and data isolation.

D) Providing privacy reviews for critical customer applications is important for assessing and mitigating privacy risks in specific applications, but it's not the primary mechanism for ensuring the security and privacy of customer data when at rest across the entire Google Cloud platform.

Therefore, C) By auditing platform privacy practices against industry standards is the most appropriate way Google Cloud ensures that customer data remains secure and private when at rest.
