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

NEW QUESTION # 58
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 is a locally managed tablespace.
C. Free space is managed using freelists.
D. It uses the database default block size.
E. It must be smaller than the smallest BIGFILE tablespace.

Answer: B,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 # 59
Which two statements describe why Database Auditing is a security requirement?

A. To monitor suspicious activity.
B. To protect against data corruption.
C. To monitor proper usage of the system and data by privileged users.
D. To alert DBAs about system issues.
E. To protect against data theft by a non-authorized user.

Answer: A,C

Explanation:
A .True. Auditing tracks suspicious actions.
B .False. That's monitoring, not auditing.
C .False. Auditing detects, doesn't prevent.
D .False. Corruption is a reliability issue.
E .True. Ensures privileged user compliance.

NEW QUESTION # 60
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. DML may be performed on tables with one or more extents in this data file during the execution of this command.
C. The "TO" clause containing the new file name must be specified even if Oracle Managed Files (OMF) is used.
D. Compressed objects in sales01.dbf will be uncompressed in sales02.dbf after the move.
E. Tables with one or more extents in this data file may be queried during the execution of this command.

Answer: B,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 # 61
Which three functions are performed by dispatchers in a shared server configuration?

A. Receiving inbound requests from processes using shared server connections.
B. Checking for outbound shared server responses on the common outbound response queue.
C. Sending each connection input request to the appropriate shared server input queue.
D. Sending shared server session responses back to requesters on the appropriate connection.
E. Broadcasting shared server session responses back to requesters on all connections.
F. Writing inbound requests to the common request queue from all shared server connections.
G. True. Dispatchers monitor the response queue.

Answer: A,B,D

Explanation:
A :True. Dispatchers return responses to clients.
B :False. Dispatchers manage queues, not write directly.
C :False. Responses are connection-specific, not broadcast.
D :True. Dispatchers receive client requests.
E :False. Queues are common, not per-connection.

NEW QUESTION # 62
Which three relationships between instances and Oracle databases are possible without using Multi-tenant?

A. One instance on one server mounting and opening one database.
B. Two or more instances on separate servers all mounting and opening the same database.
C. One instance on one server mounting and opening multiple databases.
D. One instance on one server that has no database mounted.
E. One instance on one server mounting multiple databases.

Answer: A,B,D

Explanation:
A .False. One instance can't mount multiple DBs without multitenant.
B .True. RAC allows multiple instances to share one DB.
C .False. Same as A; not possible without CDB.
D .True. An instance can start in NOMOUNT with no DB.
E .True. Standard single-instance configuration.
