Oracle Database 23ai Administration Associate Sample Questions (Q61-Q66):

NEW QUESTION # 61
Which three statements are true about an SPFILE?

A. It can be created by SYS from an idle instance.
B. It contains only static initialization parameters.
C. It contains initialization parameters whose values can be changed using the ALTER SYSTEM statement.
D. It must exist for a database instance to start.
E. It can be used to create a PFILE.

Answer: A,C,E

Explanation:
A .True. CREATE SPFILE FROM PFILE works when idle.
B .False. Includes dynamic parameters too.
C .True. CREATE PFILE FROM SPFILE generates a PFILE.
D .False. A PFILE can start the instance if no SPFILE exists.
E .True. Dynamic parameters (e.g., DB_CACHE_SIZE) are modifiable.

NEW QUESTION # 62
Which two statements are true concerning logical and physical database structures?

A. A segment can span multiple data files in some tablespaces.
B. All tablespaces may have one or more data files.
C. A segment's blocks can be of different sizes.
D. Segments can span multiple tablespaces.
E. A segment might have only one extent.
F. A segment's blocks can be of different sizes.

Answer: A,E

Explanation:
False. All blocks in a segment use the tablespace's block size (e.g., 8KB). While a database can have tablespaces with different block sizes (e.g., 8KB, 32KB), a single segment's blocks are uniform, as it resides in one tablespace.
Explanation:
Logical structures (e.g., segments, extents) map to physical structures (e.g., data files, blocks). Let's dissect each option:
A : A segment can span multiple data files in some tablespaces.
True. A segment (e.g., a table or index) is a logical entity stored in a tablespace. In a smallfile tablespace (default in Oracle), a segment's extents can span multiple data files if the tablespace has multiple files and space allocation requires it. This is common in large tables or when autoextend adds new files.
Mechanics:Oracle allocates extents across available data files in a round-robin fashion (with ASSM) or as needed, ensuring the segment's data is distributed. This doesn't apply to bigfile tablespaces, which use a single data file.
Example:A 10GB table in a tablespace with two 5GB data files will span both.
B : Segments can span multiple tablespaces.
False. A segment is confined to a single tablespace. Oracle enforces this to maintain logical separation (e.g., a table's data stays in its assigned tablespace). Partitioned tables can have partitions in different tablespaces, but each partition is a separate segment.
Why Not:The segment header and extent map reside in one tablespace, preventing cross-tablespace spanning for a single segment.
C : A segment might have only one extent.
True. A segment starts with one extent upon creation (e.g., a small table or index). If no further growth occurs, it remains a single-extent segment. This is common with small objects or when INITIAL extent size suffices.
Mechanics:In locally managed tablespaces (default), the initial extent is allocated based on INITIAL or tablespace defaults (e.g., 64KB), and additional extents are added only as needed.
D : All tablespaces may have one or more data files.
False. Bigfile tablespaces are restricted to one data file (up to 128TB). Smallfile tablespaces (traditional) can have multiple data files (up to 1022), but the "all" phrasing makes this false due to bigfile exceptions.
Clarification:The question's intent may assume smallfile tablespaces, but Oracle 23ai supports both types.

NEW QUESTION # 63
What are Optimizer Statistics?

A. Optimizer Statistics are statistics about data distribution within Oracle Datafiles.
B. Optimizer Statistics are part of system performance statistics stored in AWR required for calculating SQL execution plans.
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 table, column, index, and system statistics used for generating efficient SQL execution plans.

Answer: D

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 # 64
Which two statements are true about the tools used to configure Oracle Net Services?

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

Answer: A,E

Explanation:
A .False. lsnrctl can start a default listener without listener.ora.
B .True. EMCC provides centralized Net Services configuration.
C .False. NetCA can run standalone, not just during installation.
D .True. Net Manager configures local naming (e.g., TNSNAMES.ORA).
E .False. Net Manager is local, not centralized like EMCC.

NEW QUESTION # 65
Which two statements are true about trace files produced by the Oracle Database server?

A. Trace file names are based on the database name concatenated with a sequential number.
B. All trace files contain error information that requires contacting Oracle Support.
C. They can be written by server processes to a file system.
D. They can be written by background processes to a file system.
E. They can be written by server processes to the Fast Recovery Area (FRA).

Answer: C,D

Explanation:
A .False. Not all trace files indicate errors; some log normal activity.
B .True. Server processes write traces (e.g., ora_s000_123.trc) to the file system.
C .True. Background processes (e.g., ora_lgwr_123.trc) also write traces.
D .False. Names include process type and PID, not just DB name and sequence.
E .False. Traces go to DIAGNOSTIC_DEST, not necessarily FRA unless configured there.
