Suggested answer: D

Explanation:

Data leakage prevention (DLP) is the process of preventing unauthorized access, disclosure, or transfer of sensitive data. In a multi-tenant cloud environment, where multiple customers share the same infrastructure and resources, DLP is a critical challenge. One of the best methods to enforce DLP in such an environment is to require tenants to implement data classification policies. Data classification policies define the types and levels of sensitivity of data, and the corresponding security controls and measures to protect them. By implementing data classification policies, tenants can ensure that their data is properly labeled, encrypted, segregated, and monitored according to their specific requirements and compliance standards. This can help prevent data leakage from accidental or malicious actions by other tenants, cloud service providers, or external parties.
