A. They describe data stored in the database.
B. They describe how data is stored in the external source.
C. They describe how the external table layer presents data to the server.
D. They are read/write tables.

Answer: C

Explanation:

B .True. Defines how external data (e.g., CSV) is mapped to SQL.
C .False. Data is external, not in the DB.
D .False. Storage is external; Oracle doesn't define it.

NEW QUESTION # 73
What are Optimizer Statistics?

A. Optimizer Statistics are table, column, index, and system statistics used for generating efficient SQL execution plans.
B. Optimizer Statistics are statistics about data distribution within Oracle Datafiles.
C. Optimizer Statistics are a set of data distribution statistics collected in real time as data is inserted, deleted, or updated, which are stored in AWR and used for generating SQL execution plans.
D. Optimizer Statistics are part of system performance statistics stored in AWR required for calculating SQL execution plans.

Answer: A

Explanation:
A .False. Not real-time; collected periodically.
B .False. Not about datafile distribution.
C .True. Includes table, column, index stats for plan generation.
D .False. Stored in data dictionary, not AWR.

NEW QUESTION # 74
Which three tasks are part of the predefined Automated Maintenance Tasks?

A. Automatic SQL Plan Management advisor tasks.
B. Automatic notification tasks.
C. Automatic Optimizer Statistics Collection.
D. Automatic segment and segment statistics advisor tasks.
E. Automatic error and failure log collection tasks.
F. Automatic Backups of the database system files.

Answer: A,C,D

Explanation:
A .False. Backups are via RMAN, not AMTs.
B .True. Stats collection is an AMT.
C .False. Error logging isn't an AMT.
D .True. SPM tasks are included.
E .False. Notifications aren't AMTs.
F .True. Segment Advisor is an AMT.

NEW QUESTION # 75
Which three tasks are performed by background processes in an Oracle database instance?

A. Registering services with Oracle Net listeners.
B. Writing dirty database block images from the buffer cache.
C. Reading database blocks into the buffer cache.
D. Creating dedicated server connections.
E. Writing redo to log files.
F. Reading database blocks into the buffer cache.

Answer: A,B,E

Explanation:
False. Server processes (foreground) read blocks into the buffer cache during user queries, not background processes.
Explanation:
Background processes manage core database operations. Let's break it down:
A : Creating dedicated server connections.
False. Dedicated server connections are created by the listener, not background processes. The listener hands off the connection to a server process (e.g., ora_s000), which isn't a background process.
B : Registering services with Oracle Net listeners.
True. The LREG process (Listener Registration, formerly PMON's role) registers services with listeners, using parameters like LOCAL_LISTENER.
Mechanics:LREG sends service details (e.g., orcl) to the listener every 60 seconds or on startup.
C : Writing redo to log files.
True. The LGWR (Log Writer) process writes redo entries from the redo log buffer to online redo log files, ensuring transaction durability.
Mechanics:Triggered by commits, log buffer fills, or checkpoints.
D : Writing dirty database block images from the buffer cache.
True. The DBWn (Database Writer) processes write modified (dirty) blocks from the buffer cache to data files, maintaining consistency.
Mechanics:Occurs at checkpoints or when free buffers are needed.

NEW QUESTION # 76
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. USR1 can revoke the CREATE VIEW privilege from USR3.
D. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked from USR3.
E. When the DBA revokes the CREATE VIEW privilege from USR1, it is revoked from USR2 but not USR3.

Answer: A,D

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.
