Oracle Database 23ai Administration Associate Sample Questions (Q46-Q51):

NEW QUESTION # 46
You have connected to a PDB to perform the administration operations of changing and verifying a system parameter that is PDB_MODIFIABLE. What is the appropriate mode to open the PDB to achieve this?

A. READ WRITE
B. RESTRICTED WRITE ONLY
C. RESTRICTED READ ONLY
D. READ ONLY

Answer: A

Explanation:
To change a PDB_MODIFIABLE parameter, the PDB must be in READ WRITE mode, allowing ALTER SYSTEM commands to modify parameters stored in the PDB's SPFILE or memory. READONLY modes prevent modifications, and no RESTRICTED WRITE ONLY mode exists.

NEW QUESTION # 47
Which three are benefits of using temp UNDO when performing DML on global temporary tables?

A. It reduces I/Os to the SYSTEM tablespace.
B. It reduces the amount of redo generated.
C. It reduces the amount of UNDO stored in the UNDO tablespace.
D. It reduces I/Os to the SYSAUX tablespace.
E. It permits DML on global temporary tables even if the database is opened read-only.

Answer: A,B,C

Explanation:
Temp UNDO, introduced in Oracle 12c and refined in 23ai, stores undo for global temporary tables (GTTs) in temporary tablespaces:
A . It permits DML on GTTs even if the database is opened read-only.False. In read-only mode, DML on GTTs is allowed regardless of temp UNDO, as GTT data is session-private, but temp UNDO doesn't specifically enable this.
B . It reduces the amount of UNDO stored in the UNDO tablespace.True. Temp UNDO stores undo in the temporary tablespace, reducing usage of the permanent UNDO tablespace.
C . It reduces I/Os to the SYSTEM tablespace.True. By avoiding permanent undo, it reduces metadata updates in the SYSTEM tablespace related to undo management.
D . It reduces the amount of redo generated.True. Temp UNDO changes are not redo-logged to the same extent as permanent undo, minimizing redo generation.
E . It reduces I/Os to the SYSAUX tablespace.False. SYSAUX is unrelated to undo management; temp UNDO affects temporary and SYSTEM tablespaces.

NEW QUESTION # 48
Which two SQL Plan Management Advisor tasks are part of Automatic Maintenance Tasks?

A. The Automatic SQL Tuning Advisor tasks, which would examine the performance of high-load SQL statements and make recommendations for those 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 Plan Management Evolve Advisor task, which evolves plans that have recently been added as the SQL plan baseline for 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.

NEW QUESTION # 49
You execute this command: CREATE BIGFILE TABLESPACE big_tbs DATAFILE '/u01/oracle/data/big_f1.dbf' SIZE 20G; Sufficient storage is available in filesystem /u01. Which two statements are true about the BIG_TBS tablespace?

A. It will always have a 32K blocksize.
B. It will be a dictionary-managed tablespace by default.
C. AUTOEXTEND is possible for the datafile.
D. It must be bigger than the largest SMALLFILE tablespace.
E. Additional data files may not be added.

Answer: C,E

Explanation:
A .False. LMT is default in 23ai.
B .True. Bigfile tablespaces have one data file only.
C .True. AUTOEXTEND works with bigfile data files.
D .False. Block size defaults to DB_BLOCK_SIZE (e.g., 8K).
E .False. No size comparison requirement.

NEW QUESTION # 50
Which two statements are true about database instances and Real Application Clusters (RAC)?

A. A RAC database can have one instance.
B. Two RAC databases can share their instances.
C. A RAC database must have two or more instances.
D. A RAC database must have three or more instances.
E. A RAC database can have instances on separate servers.

Answer: A,E

Explanation:
A .False. RAC can run with one instance (degraded mode).
B .True. Possible, though not typical for RAC.
C .False. No minimum of three.
D .True. RAC instances run on separate nodes.
E .False. Instances are DB-specific in RAC.
