What are the four types of privileges?

The four types of privileges in Teradata are categorized as Automatic, Explicit, Implicit, and Inherited.

Automatic privileges are granted to certain users or roles by default without any specific action required from the administrator. These privileges help streamline access management by automatically giving necessary permissions to users based on their roles or system-defined categories.

Explicit privileges are those that are directly granted to users or roles by an administrator. These may include permissions to execute specific queries or access certain data tables. By explicitly defining these privileges, administrators can maintain tighter control over who has access to different system resources.

Implicit privileges arise through the granting of explicit privileges and encompass access that is automatically provided based on those explicit permissions. For example, if a user is granted permission to a table, they may automatically have access to perform certain operations on that table without needing additional grants.

Inherited privileges are those that a user or role acquires through other roles that they belong to. This feature leverages a hierarchical structure of roles, simplifying the management of permissions by allowing derived access rights based on membership in higher-level roles.

The other choices include terms that do not accurately reflect the privilege types in Teradata, either by mislabeling or combining incorrect concepts, thus indicating that understanding the correct types is essential
