Oracle Database 23ai Administration Associate Sample Questions (Q21-Q26):

NEW QUESTION # 21
Examine this command: ALTER DATABASE MOVE DATAFILE 'u01/sales1.dbf' TO 'u01/sales01.dbf' REUSE; Which two statements are true?

A. The tablespace containing SALES1.DBF must be altered OFFLINE before executing the command.
B. If Oracle Managed Files (OMF) is used, then the file is renamed but moved to DB_CREATE_FILE_DEST.
C. The file is renamed and stored in the same location.
D. The tablespace containing SALES1.DBF must be altered READ ONLY before executing the command.
E. DML may be performed on tables with one or more extents in this data file during the execution of this command.

Answer: C,E

Explanation:
This command moves/renames a data file online. Let's evaluate:
A . DML may be performed on tables with one or more extents in this data file during the execution of this command.
True. Introduced in 12c and refined in 23ai, MOVE DATAFILE is an online operation, allowing DML (e.g., INSERT, UPDATE) on tables within the file. Oracle ensures consistency via redo and undo.
Mechanics:The file is copied to the new location/name while tracking changes, then switched atomically.
Practical Use:Minimizes downtime in production systems.
B . If Oracle Managed Files (OMF) is used, then the file is renamed but moved to DB_CREATE_FILE_DEST.
False. With OMF, omitting the TO clause would place the file in DB_CREATE_FILE_DEST, but here, TO 'u01/sales01.dbf' explicitly specifies the target, overriding OMF defaults.
Mechanics:OMF only applies if the destination is unspecified (e.g., MOVE DATAFILE ... without TO).
Why Incorrect:Explicit path trumps OMF behavior.
C . The tablespace containing SALES1.DBF must be altered READ ONLY before executing the command.
False. READ ONLY isn't required; the operation is online and supports active use.
Why Incorrect:Conflicts with Oracle's online move feature.
D . The file is renamed and stored in the same location.
True. The command renames /u01/sales1.dbf to /u01/sales01.dbf (correcting u01 to /u01 as a Windows/Unix typo), keeping it in /u01/. REUSE allows overwriting if sales01.dbf exists.
Mechanics:File is copied and renamed in-place within the same filesystem directory.
E . The tablespace containing SALES1.DBF must be altered OFFLINE before executing the command.
False. Offline mode isn't needed; the online move handles activetablespaces.

NEW QUESTION # 22
You start your database instance in NOMOUNT state. Which two actions are performed?

A. The control files are opened.
B. The consistency of the database is checked.
C. SYS can access the database.
D. All required background processes are started.
E. Memory is allocated for the SGA.

Answer: D,E

Explanation:
A .True. Background processes (e.g., PMON) start.
B .False. Consistency checks require MOUNT.
C .False. Control files open in MOUNT.
D .True. SGA is allocated at startup.
E .False. SYS access requires OPEN.

NEW QUESTION # 23
You execute this command: CREATE SMALLFILE TABLESPACE sales DATAFILE '/u01/app/oracle/sales01.dbf' SIZE 5G SEGMENT SPACE MANAGEMENT AUTO; Which two statements are true about the SALES tablespace?

A. Any data files added to the tablespace must have a size of 5 gigabytes.
B. It must be smaller than the smallest BIGFILE tablespace.
C. It uses the database default block size.
D. It is a locally managed tablespace.
E. Free space is managed using freelists.

Answer: C,D

Explanation:
A . Free space is managed using freelists.False. The SEGMENT SPACE MANAGEMENT AUTO clause specifies Automatic Segment Space Management (ASSM), which uses bitmaps to track free space, not freelists (used in Manual Segment Space Management).
B . It uses the database default block size.True. The BLOCKSIZE clause is not specified in the command, so the tablespace inherits the database's default block size (typically 8K unless altered via DB_BLOCK_SIZE).
C . It must be smaller than the smallest BIGFILE tablespace.False. There's no such restriction; SMALLFILE and BIGFILE tablespaces differ in structure (multiple vs. single data file), not mandated size relationships.
D . It is a locally managed tablespace.True. In Oracle 23ai, all tablespaces created without an explicit EXTENT MANAGEMENT DICTIONARY clause are locally managed by default, using extent allocation bitmaps in the data file headers.
E . Any data files added to the tablespace must have a size of 5 gigabytes.False. The initial data file is 5G, but additional data files can have different sizes when added using ALTER TABLESPACE ... ADD DATAFILE.

NEW QUESTION # 24
Which two tasks can you perform using DBCA for databases?

A. Change the standard block size of an existing database.
B. Register a new database with an available Enterprise Manager Management server.
C. Configure incremental backups for a new database.
D. Configure a nonstandard block size for a new database.
E. Enable flashback database for an existing database.

Answer: B,D

Explanation:
A .False. Backups are configured via RMAN, not DBCA.
B .True. DBCA allows nonstandard block sizes during DB creation.
C .True. DBCA can register new DBs with EM.
D .False. Block size is fixed post-creation.
E .False. Flashback is enabled via SQL, not DBCA for existing DBs.

NEW QUESTION # 25
Script abc.sql must be executed to perform a certain task. User HR with password HR exists in the target database and the account is unlocked. The TNSNAMES.ORA file is up to date. Examine this command attempted by the user: $ sqlplus hr/hr@orcl @abc. What will happen and why?

A. The command succeeds and HR will be connected to the orcl database instance, and the abc script will be executed.
B. The command fails and reports an error because @ is used twice.
C. The command succeeds and HR will be connected to the orcl database and after logging out to the abc database.
D. The command fails because the script must refer to the full path name.
E. The command succeeds and HR will be connected to the orcl database instance, and the abc script will be executed.

Answer: A

Explanation:
A .False. "Logging out to the abc database" is nonsensical; abc is a script, not a database.
B .False. SQL*Plus finds abc.sql in the current directory by default; a full path isn't required unless it's elsewhere.
C .False. The first @ specifies the TNS alias (orcl), the second runs the script (@abc); this is valid syntax.
D & E.True (identical options). The command connects to orcl via TNSNAMES.ORA, authenticates HR, and executes abc.sql.
Mechanics:sqlplus hr/hr@orcl resolves orcl to a listener address, connects, and@abc runs the script post-login.
