Oracle Database 23ai Administration Associate Sample Questions (Q76-Q81):

NEW QUESTION # 76
Which three statements are true about resumable space allocation in Oracle databases?

A. Resumable space allocation is only possible with locally managed tablespaces.
B. Resumable space allocation may be enabled for some sessions and not others.
C. A user's session may be suspended and resumed multiple times.
D. A user's session may be suspended even if the user has the UNLIMITED TABLESPACE system privilege.
E. The AFTER SUSPEND event trigger can itself be suspended due to space conditions.
F. All sessions must have the same timeout value when waiting for resumable space allocations.

Answer: B,C,D

Explanation:
A .True. Enabled per session with ALTER SESSION ENABLE RESUMABLE.
B .True. Multiple suspensions can occur in one session.
C .False. Works with dictionary-managed tablespaces too.
D .False. Timeout is session-specific.
E .True. Privilege doesn't prevent suspension; quota limits do.
F .False. Triggers execute but can't suspend themselves.

NEW QUESTION # 77
Which two statements are true concerning logical and physical database structures?

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

Answer: D,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 # 78
Which three tasks are part of the predefined Automated Maintenance Tasks?

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

Answer: B,C,F

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 # 79
One of your database instances was shut down normally and then started in NOMOUNT state. You then executed this command: ALTER DATABASE MOUNT; Which two of these actions are performed?

A. Oracle shared memory structures are allocated.
B. Online data files are opened.
C. The alert log has instance startup details written to it.
D. Online redo logs are opened.
E. Control files are read.
F. The initialization parameter file is read.

Answer: C,E

Explanation:
A .False. Data files open in OPEN.
B .False. Redo logs open in OPEN.
C .False. PFILE/SPFILE is read at NOMOUNT.
D .False. SGA is allocated at NOMOUNT.
E .True. Alert log records mount event.
F .True. Control files are read in MOUNT.

NEW QUESTION # 80
Which two SQL Plan Management Advisor tasks are part of Automatic Maintenance Tasks?

A. The Automatic SQL Plan Management Evolve Advisor task, which evolves plans that have recently been added as the SQL plan baseline for statements.
B. The Automatic SQL Performance Analyzer task, which is used to provide details about impact of database changes to application SQL batch.
C. The Automatic Index Advisor task, which is used to create and maintain table indexes based on the DML load and operations.
D. The Automatic SQL Access Advisor task, which is used to manage an application SQL load.
E. The Automatic SQL Tuning Advisor tasks, which would examine the performance of high-load SQL statements and make recommendations for those statements.

Answer: A,E

Explanation:
Automatic Maintenance Tasks (AMTs) in 23ai optimize database performance. Let's explore:
A .False. SQL Access Advisor exists but isn't an AMT; it's manual or invoked separately.
B .False. SQL Performance Analyzer assesses change impacts but isn't part of AMTs.
C .False. No "Automatic Index Advisor" exists as an AMT; Auto Index is a separate feature.
D .True. The SPM Evolve Advisor task (part of ORA$AUTOTASK) automatically evolves SQL plan baselines, testing and accepting new plans.
Mechanics:Runs in maintenance windows, managed by DBMS_SPM.
E .True. SQL Tuning Advisor (STA) runs automatically via AMTs, tuning high-load SQL.
Mechanics:Identifies candidates from AWR and suggests indexes, profiles, etc.
