Answer:

B, C, F

Explanation:

Roles in Oracle manage privileges efficiently. Let’s dive into each option:

A. Roles must be password protected.

Explanation:False. Roles can be password-protected (e.g., CREATE ROLE mgr IDENTIFIED BY secret), but it’s optional. Non-protected roles (default) are enabled automatically if granted, requiring no password.

Mechanics:Password-protected roles need SET ROLE mgr IDENTIFIED BY secret, enhancing security for sensitive privileges.

B. Roles may be granted to other roles.

Explanation:True. Roles can form hierarchies (e.g., GRANT clerk TO mgr), allowing nested privilege management.

Mechanics:A user with mgr inherits clerk privileges indirectly. Revoking clerk from mgr cascades appropriately.

Practical Use:Simplifies complex privilege structures in large organizations.

C. The SET ROLE statement can enable one or more roles for a session.

Explanation:True. SET ROLE role1, role2; activates specified roles for the session, assuming they’re granted and not password-protected (or password is provided).

Mechanics:Enabled roles grant their privileges immediately within the session scope.

D. Object privileges may not be granted to roles.

Explanation:False. Object privileges (e.g., GRANT SELECT ON emp TO clerk) are a primary use of roles, making this statement incorrect.

Why Incorrect:Roles are designed for this purpose, contradicting the option.

E. All roles granted to a user are set on default when the user logs in.

Explanation:False. Only roles marked as DEFAULT ROLE (via ALTER USER ... DEFAULT ROLE role1) are enabled at login. Non-default roles require SET ROLE.

Mechanics:Check via SELECT * FROM DBA_ROLE_PRIVS WHERE DEFAULT_ROLE='YES'.

F. The SET ROLE statement can disable one or more roles for a session.

Explanation:True. SET ROLE NONE disables all roles, or SET ROLE role1 implicitly disables others not listed, providing granular control.

Practical Use:Useful for testing or restricting privileges temporarily.

Question 2

Which two are benefits of external tables?

Options:

They support DELETEs, which transparently deletes records in the file system as if they were table rows.

They can be queried while the database is in the MOUNT state like dynamic performance views.

They support UPDATEs, which transparently updates records in the file system as if they were table rows.

They can be queried, transformed, and joined with other tables without having to load the data first.

The results of a complex join or aggregating function or both can be unloaded to a file for transportation to other systems.

Question 3

Which two statements are true about the UNLIMITED TABLESPACE system privilege and space quota?

Options:

It allows a user to have unlimited space in any tablespace in the database.

It is overridden by a space quota specified for the user.

It allows a user to have unlimited space only in their default permanent tablespace.

It allows a role to have unlimited space in any tablespace in the database.

By default, users have no quota on their default permanent tablespace.
