NEW QUESTION # 71
Which three are true aboutprivileges and roles?

A. PUBIIC can be revoked from a user.
B. System prilgese always set prilge for an entire database.
C. A user has all object privileges for every object in their schema by default.
D. PUBLIC acts as a default role granted to every user in a database.
E. A role is owned by the user who created it.
F. All roles are owned by the sYs schema.
G. A role can contain a combination of several privileges and roles.

Answer: C,D,G

Explanation:
In Oracle Database 12c, the following are true about privileges and roles:
* Option B: PUBLIC acts as a default role granted to every user in a database.
* The PUBLIC role is a special role that is automatically granted to all users. It can be used to provide privileges to every user.
* Option C: A user has all object privileges for every object in their schema by default.
* By default, a user has all privileges on the objects they own, i.e., the objects in their schema.
* Option D: A role can contain a combination of several privileges and roles.
* Roles are designed to group together privileges and other roles, making it easier to manage and assign security settings to users.
Options A, E, F, and G are incorrect because:
* Option A: System privileges can be set for specific schemas or objects, not always for the entire database.
* Option E: Roles are not "owned" by users in the traditional sense of ownership; they are managed by the database and can be granted to any user.
* Option F: Not all roles are owned by the SYS schema; roles are a database security concept and do not have an "owner".
* Option G: The PUBLIC role is not something that can be revoked from a user; it is a default role that exists for all users.
