Which of the following statements applies to retention settings?

The statement indicating that you cannot remove the configured data retention settings once you configure them is correct. In Salesforce Marketing Cloud, once retention settings are established for a data extension, they are intended to enforce a specific retention policy that cannot be simply undone. This ensures compliance with data governance and regulatory standards such as GDPR, where data retention policies are crucial for managing personal data appropriately.

Setting this policy reinforces the integrity of the data management practices within the platform. When an organization sets these parameters, they are making a strategic decision about how long to retain customer data. Consequently, allowing for the removal of these settings later could lead to potential risks or violations of data policies. Thus, maintaining the integrity of the retention settings supports consistent data usage and regulatory compliance.

The other options describe scenarios that are not applicable in the context of how retention settings operate within Salesforce Marketing Cloud, highlighting the clarity and strictness of data governance practices in the platform.
