OneTrust Certified Privacy Professional Practice Exam

The primary purpose of data mapping in privacy compliance is to understand how personal data flows within the organization. This process involves identifying and documenting the data lifecycle, including its collection, storage, use, and sharing practices. By establishing a clear visual representation of data flows, organizations can better assess their compliance with privacy regulations and identify potential risks associated with data handling and protection.

Data mapping is essential for identifying which personal data is collected, the purposes for which it is used, and with whom it is shared. This comprehensive understanding helps organizations ensure they meet legal obligations, such as providing transparency to individuals about their data processing activities. Additionally, it enables organizations to implement necessary controls and measures that align with data protection principles, ultimately guiding their compliance strategy more effectively.

The other choices focus on aspects that, while related to data management and protection, do not capture the core intent of data mapping within the context of privacy compliance. Generating revenue from data sales is not a compliance activity, restricting access to data addresses security but not the flow or lifecycle of data, and ensuring data is fully erased pertains to data retention policies rather than the broader understanding of data flows essential for compliance.
