Oracle Database 23ai Administration Associate Sample Questions (Q79-Q84):

NEW QUESTION # 79
You are going to perform a hot remote clone of PDB1 from CDB1 as TESTPDB in CDB2. Which of the following is a necessary prerequisite for the hot remote clone?

A. PDB1 must be in read-only mode.
B. Both CDBs need to be in local undo mode.
C. PDB1 must be taken offline before the cloning process begins.
D. TESTPDB must be in read-only mode after the cloning process is complete.

Answer: A

Explanation:
C .True. Hot cloning requires the source PDB (PDB1) to be read-only to ensure consistency during the clone. Others are not prerequisites.

NEW QUESTION # 80
What are Optimizer Statistics?

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

Answer: B

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 # 81
In which two ways would you disable timing information collected for wait events and much of the performance monitoring capability of the database?

A. By setting the TIMED_STATISTICS system parameter to FALSE.
B. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.LEVEL(BASIC).
C. By executing the PL/SQL procedure DBMS_TIME_STATISTIC.DISABLE(TRUE).
D. By setting the TIMED_STATISTICS_LEVEL system parameter to FALSE.
E. By setting the STATISTICS_LEVEL parameter to BASIC.

Answer: A,E

Explanation:
A .True. TIMED_STATISTICS = FALSE disables timing data collection.
B .False. No such procedure exists.
C .False. No TIMED_STATISTICS_LEVEL parameter exists.
D .True. STATISTICS_LEVEL = BASIC disables most performance monitoring.
E .False. No such procedure exists.

NEW QUESTION # 82
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. The alert log has instance startup details written to it.
B. Online redo logs are opened.
C. Oracle shared memory structures are allocated.
D. The initialization parameter file is read.
E. Online data files are opened.
F. Control files are read.

Answer: A,F

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 # 83
Which three are benefits of using temp UNDO when performing DML on global temporary tables?

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

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.
