Which of the following describes the relationship of user and privileges?

The assertion that privileges can be inherited is accurate because in a database management system like Teradata, privileges can indeed be assigned to user roles or groups, and users configured under those roles can inherit the associated permissions. This mechanism allows for efficient management of user permissions by applying privileges at a higher level (roles or groups) rather than assigning them individually to each user. Consequently, when a user is added to a role with certain privileges, they automatically gain access to the capabilities associated with that role without the need for explicit individual permission settings.

In many systems, this inheritance not only simplifies administrative tasks but also enhances security and control over data access, ensuring that users have access only to the necessary privileges that their roles dictate. This organizational structure is crucial for large systems with numerous users and complex data access needs, as it facilitates scalability and reduces administrative overhead.

Regarding the other options: while user roles are highly relevant in managing permissions, saying they are irrelevant fails to recognize their importance in privilege assignment. The claim that privileges are always explicit is misleading, as inherited privileges signify a more implicit authorization. Lastly, the notion that privileges cannot be revoked is incorrect because users can have their privileges taken away as needed, which is essential for maintaining security and compliance in a dynamic environment.
