Oracle Database 23ai Administration Associate Sample Questions (Q58-Q63):

NEW QUESTION # 58
What memory structure caches the data dictionary providing access to all database user processes?

A. The Java Pool
B. The Streams Pool
C. The Large Pool
D. The Shared Pool

Answer: D

Explanation:
D .True. The Shared Pool caches data dictionary metadata (e.g., table definitions) in the Library Cache and Dictionary Cache, accessible to all processes. Others serve different purposes (e.g., Large Pool for backups).

NEW QUESTION # 59
Examine this command: ALTER DATABASE MOVE DATAFILE '/u01/sales01.dbf' TO '/u02/sales02.dbf'; Which two statements are true?

A. It overwrites any existing file with the name sales02.dbf in /u02 by default.
B. Compressed objects in sales01.dbf will be uncompressed in sales02.dbf after the move.
C. DML may be performed on tables with one or more extents in this data file during the execution of this command.
D. The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.
E. Tables with one or more extents in this data file may be queried during the execution of this command.

Answer: C,E

Explanation:
The ALTER DATABASE MOVE DATAFILE command relocates a data file to a new location while the database remains online, introduced in Oracle 12c and enhanced in subsequent releases like 23ai. Let's evaluate each option:
A . DML may be performed on tables with one or more extents in this data file during the execution of this command.True. The move operation is online by default in Oracle 23ai, allowing DML (INSERT, UPDATE, DELETE) operations on tables within the data file being moved. The database ensures consistency using redo and undo mechanisms.
B . It overwrites any existing file with the name sales02.dbf in /u02 by default.False. By default, the command does not overwrite an existing file unless the REUSE clause is specified (e.g., ALTER DATABASE MOVE DATAFILE ... REUSE). Without it, the command fails if the target file exists.
C . The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.False. When OMF is enabled (via DB_CREATE_FILE_DEST), the TO clause is optional. If omitted, Oracle automatically generates a file name and places it in the OMF destination.
D . Compressed objects in sales01.dbf will be uncompressed in sales02.dbf after the move.False. The move operation is a physical relocation of the data file; it does not alter the logical structure or compression state of objects within it. Compressed data remains compressed.
E . Tables with one or more extents in this data file may be queried during the execution of this command.True. The online nature of the move allows queries (SELECT statements) to proceed without interruption, leveraging Oracle's multi-version consistency model.

NEW QUESTION # 60
You execute the SHUTDOWN ABORT command. Which two statements are true?

A. Data files are closed normally.
B. A checkpoint is written.
C. Subsequent instance startup performs instance recovery.
D. Subsequent instance startup performs media recovery.
E. Uncommitted transactions are not rolled back by the shutdown.

Answer: C,E

Explanation:
A .False. No checkpoint occurs with ABORT.
B .False. Instance recovery, not media recovery, is needed.
C .True. Crash recovery rolls back uncommitted changes on startup.
D .False. Files aren't closed cleanly with ABORT.
E .True. Shutdown doesn't roll back; recovery does.

NEW QUESTION # 61
Which three statements are true about the tools used to configure Oracle Net Services?

A. Enterprise Manager Cloud Control can be used to centrally configure listeners on any managed database server.
B. Enterprise Manager Cloud Control can be used to centrally configure net service names for any database server target.
C. Oracle Net Manager can be used to centrally configure listeners on any database server target.
D. Oracle Net Manager can be used to locally configure naming methods on a database server.
E. The lsnrctl utility requires a listener.ora file to exist before it is started.
F. The Oracle Net Configuration Assistant is only used when running the Oracle installer.

Answer: A,B,D

Explanation:
A .False. Net Manager is local, not centralized.
B .False. NetCA can run standalone.
C .True. EMCC manages service names centrally.
D .True. EMCC configures listeners on managed targets.
E .False. lsnrctl starts a default listener if no listener.ora exists.
F .True. Net Manager configures local tnsnames.ora.

NEW QUESTION # 62
Which three tasks are performed by background processes in an Oracle database instance?

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

Answer: B,D,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.
