Oracle Database 23ai Administration Associate Sample Questions (Q60-Q65):

NEW QUESTION # 60
Examine these commands:
[oracle@host01 ~]$ sqlplus u1/oracle
SQL> SELECT * FROM emp;
ENO ENAME DN
-------------------------
1 Alan 2
2 Ben 2
SQL> exit
[oracle@host01 ~]$ cat emp.dat
1, Alan, 2
3, Curl, 4
4, Bob, 4
[oracle@host01 ~]$ sqlldr u1/oracle TABLE=emp
Which two statements are true?

A. It overwrites the data for Alan and adds data for Curl and Bob.
B. It overwrites all data in EMP with data from EMP.DAT.
C. It generates a SQL script that it uses to load data from EMP.DAT to EMP.
D. It appends data from EMP.DAT to EMP.
E. It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.

Answer: D,E

Explanation:
SQL*Loader (sqlldr) loads data from external files into Oracle tables. The command sqlldr u1/oracle TABLE=emp uses defaults since no control file is specified. Let's evaluate:
A . It overwrites the data for Alan and adds data for Curl and Bob.
False. SQLLoader's default mode is APPEND, not REPLACE. It doesn't "overwrite" existing rows unless REPLACE or TRUNCATE is specified in a control file. Here, row 1, Alan, 2 exists, and SQLLoader will either skip it (if a primary key rejects duplicates) or raise an error, but it won't overwrite. 3, Curl, 4 and 4, Bob, 4 are appended.
Mechanics:Without a control file, SQL*Loader assumes APPEND and matches columns positionally (ENO, ENAME, DN).
B . It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
True. SQL*Loader always generates a log file (e.g., emp.log) when invoked. With no control file specified, it auto-generates one internally and logs it, including entries like LOAD DATA INFILE 'emp.dat' APPEND INTO TABLE emp FIELDS TERMINATED BY ',' (ENO, ENAME, DN). This can be reused.
Practical Use:The log's control section is editable for future runs (e.g., changing to REPLACE).
C . It appends data from EMP.DAT to EMP.
True. Default behavior without a control file is APPEND, adding new rows (3, Curl, 4 and 4, Bob, 4) to EMP. Existing rows (1, Alan, 2, 2, Ben, 2) remain unless constrained (e.g., unique key violations).
Mechanics:SQL*Loader processes each line of emp.dat, skipping duplicates if constrained, appending otherwise.
D . It generates a SQL script that it uses to load data from EMP.DAT to EMP.
False. SQL*Loader doesn't generate SQL scripts; it uses direct path or conventional path loading, not SQL scripts. The log contains control file syntax, not a script.
E . It overwrites all data in EMP with data from EMP.DAT.
False. REPLACE or TRUNCATE would overwrite, but these require a control file with those options. Default APPEND preserves existing data.

NEW QUESTION # 61
What are Optimizer Statistics?

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

Answer: C

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 # 62
Which statement regarding PDBs (Pluggable Databases) is correct?

A. You can drop a PDB as long as it is not the PDB seed.
B. You cannot drop a source PDB of a refreshable PDB.
C. When the relocation of a PDB is finished, the source PDB must be dropped.
D. You can drop an application root along with the associated PDBs.

Answer: A

Explanation:
A .True. Any PDB except PDB$SEED can be dropped.
B .False. Source PDBs of refreshable clones can be dropped after cloning.
C .False. Dropping an application root requires explicit handling of PDBs.
D .False. Relocation doesn't mandate dropping the source PDB.

NEW QUESTION # 63
Which of the following statements is true about external tables?

A. They describe how data is stored in the external source.
B. They are read/write tables.
C. They describe data stored in the database.
D. They describe how the external table layer presents data to the server.

Answer: D

Explanation:
A .False. External tables are read-only.
B .True. Defines how external data (e.g., CSV) is mapped to SQL.
C .False. Data is external, not in the DB.
D .False. Storage is external; Oracle doesn't define it.

NEW QUESTION # 64
Which three functions are performed by dispatchers in a shared server configuration?

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

Answer: B,C,E

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.
