NEW QUESTION # 44
Which three statements are true about roles?

• A. All roles granted to a user are set on default when the user logs in.
• B. Object privileges may not be granted to roles.
• C. The SET ROLE statement can enable one or more roles for a session.
• D. Roles must be password protected.
• E. Roles may be granted to other roles.
• F. The SET ROLE statement can disable one or more roles for a session.

Answer: C,E,F

Explanation:
Roles in Oracle manage privileges efficiently. Let's dive into each option:
A . Roles must be password protected.
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.
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.
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.
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.
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.
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.

NEW QUESTION # 45
Which statement is true about the PDB_DBA role granted to a local user during the creation of a new PDB?

• A. The role has the privileges to administer the PDB.
• B. No privileges are provided with the PDB_DBA role.
• C. The role has the privileges to perform DDL operations on all local schema objects.
• D. The role has the privileges to create and manage users within the PDB.

Answer: A

Explanation:
A .True. PDB_DBA grants admin rights (e.g., CREATE SESSION, ALTER SYSTEM) within the PDB.
B .False. DDL on objects requires ownership or explicit grants.
C .False. User management needs CREATE USER privilege, not inherent.
D .False. It includes multiple privileges, not none.

NEW QUESTION # 46

E .False. Can manage stopped instances via agents.

NEW QUESTION # 47
As the DBA, you execute this command: GRANT CREATE VIEW TO usr1 WITH ADMIN OPTION; USR1 then executes: GRANT CREATE VIEW TO usr2 WITH ADMIN OPTION; USR2 then executes: GRANT CREATE VIEW TO usr3; Which statement is true?

• A. When the DBA revokes the CREATE VIEW privilege from USR1, it is neither revoked from USR2 nor USR3.
• B. The DBA can revoke only ADMIN OPTION from USR1.
• C. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked from USR3.
• D. When the DBA revokes the CREATE VIEW privilege from USR1, it is revoked from USR2 but not USR3.
• E. USR1 can revoke the CREATE VIEW privilege from USR3.

Answer: A,C

Explanation:
A .False. Revoking from USR1 doesn't cascade due to WITH ADMIN OPTION.
B .True. Revoking from USR2 cascades to USR3 because USR2 granted it.
C .False. DBA can revoke the full privilege, not just ADMIN OPTION.
D .False. USR1 can't revoke from USR3 directly; only the grantor (USR2) can.
E .True. WITH ADMIN OPTION breaks the revoke chain from USR1 onward.

NEW QUESTION # 48
Which three Oracle database space management features will work with both Dictionary and Locally managed tablespaces?

• A. Online table segment shrink.
• B. Capacity planning growth reports based on historical data in the Automatic Workload Repository (AWR).
• C. Online index segment shrink.
• D. Automatic data file extension (AUTOEXTEND).
• E. Oracle Managed Files (OMF).

Answer: B,D,E

Explanation:
Dictionary-managed tablespaces (DMTs) use the data dictionary for extent management, whilelocally managed tablespaces (LMTs) use bitmaps. Let's evaluate compatibility:
A . Capacity planning growth reports based on historical data in the Automatic Workload Repository (AWR).
True. AWR tracks space usage (e.g., DBA_HIST_TBSPC_SPACE_USAGE) regardless of tablespace type, enabling growth reports for both DMTs and LMTs.
Mechanics:MMON collects metrics like segment growth, stored in SYSAUX, accessible via EM or scripts.
Practical Use:Helps predict when to add data files, universal across management types.
B . Online table segment shrink.
False. ALTER TABLE ... SHRINK SPACE requires LMTs with Automatic Segment Space Management (ASSM), unavailable in DMTs, which lack bitmap-based free space tracking.
Why Incorrect:DMTs use freelists, incompatible with shrink operations.
C . Online index segment shrink.
False. Like tables, ALTER INDEX ... SHRINK SPACE requires LMTs with ASSM, not supported in DMTs.
Why Incorrect:Same limitation as B; DMTs can't compact online.
D . Oracle Managed Files (OMF).
True. OMF automates file naming and placement (via DB_CREATE_FILE_DEST) for both DMTs and LMTs, agnostic to extent management.
Mechanics:Example: CREATE TABLESPACE ts1; creates an OMF file in either type.
Edge Case:DMTs are rare in 23ai, but OMF still applies.
E . Automatic data file extension (AUTOEXTEND).
True. AUTOEXTEND ON allows data files to grow as needed, supported in both DMTs and LMTs since early versions.
Mechanics:ALTER DATABASE DATAFILE ... AUTOEXTEND ON NEXT 100M; works universally.

NEW QUESTION # 49
You unplugged a PDB to plug it into another CDB with the following command: SQL> ALTER PLUGGABLE DATABASE pdb1 UNPLUG INTO '/tmp/pdb1.pdb'; Which statement is true prior to plugging the PDB into the other CDB?

• A. The PDB archive file must be copied to the target CDB.
• B. PDB archive file and only the user-defined tablespaces must be copied to the target CDB.
• C. The PDB manifest, the data files, and the PDB archive file must be copied to the target CDB.
• D. The PDB manifest and all the datafiles must be copied to the target CDB.

Answer: C

Explanation:
D .True. The .pdb file (archive) contains the manifest and data files; all must be copied to the target CDB for plugging.
A-C .False. The archive alone isn't enough; all components are needed.

NEW QUESTION # 50

• B. Analysis of all privileges used by the SYS user.
• C. Analysis of privileges that a user has on their own schema objects.
• D. Analysis of privileges that a user has on other schemas' objects.
• E. Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.

Answer: A,E

Explanation:
A .False. Limited to captured privileges, not all schema objects.
B .False. SYS is excluded from capture.
C .True. Captures indirect role privileges used.
D .True. Captures direct role privileges used.
E .False. Focus is on roles, not self-owned objects broadly.
