NEW QUESTION # 43
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 generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
C. It appends data from EMP.DAT to EMP.
D. It generates a SQL script that it uses to load data from EMP.DAT to EMP.
E. It overwrites all data in EMP with data from EMP.DAT.

Answer: B,C

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 # 44
Which two statements are true about trace files produced by the Oracle Database server?

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

Answer: C,E

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.

NEW QUESTION # 45
What is the result of the following command? ALTER PLUGGABLE DATABASE PDB1 DISCARD STATE;

A. PDB1 is reverted to its default properties, which includes automatic opening after a CDB restart.
B. It is unnecessary if the PDB is in the process of being upgraded.
C. It should be used whenever PDB1 open mode needs to be changed.
D. PDB1 is reverted to its default properties, which includes not to automatically open after a CDB restart.

Answer: D

Explanation:
A .False. DISCARD STATE isn't tied to upgrades; it resets PDB startup behavior.
B .True. Discards saved state, reverting PDB1 to manual open mode (not auto-open) after CDB restart.
C .False. Default is not auto-open; it's manual unless explicitly saved as OPEN.
D .False. Used for state management, not general mode changes (e.g., OPEN READ WRITE).

NEW QUESTION # 46
You want to apply the principle of Least Privilege in all your live databases. One of your requirements is to revoke unnecessary privileges from all users who have them using Privilege Analysis. Which three types of analyses can be done using the DBMS_PRIVILEGE_CAPTURE package?

A. Analysis of privileges that a user has on their own schema objects that they did use.
B. Analysis of all privileges used by all users including administrative users in the database.
C. Analysis of privileges granted indirectly to a role that are then used by a user who has beengranted that role.
D. Analysis of all privileges used by all users but excluding administrative users in the database.
E. Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.
F. Analysis of privileges that a user has on their own schema objects that they did not use.

Answer: A,C,F

Explanation:
A .True. Captures unused self-owned object privileges.
B .False. SYS is excluded from capture.
C .False. No exclusion option for admin users.
D .False. Direct role grants aren't separately analyzed.
E .True. Tracks indirect role privileges used.
F .True. Identifies used self-owned privileges.

NEW QUESTION # 47
Which three statements are true about Deferred Segment Creation in Oracle databases?

A. It is supported for Index Organized Tables (IOTs) contained in locally managed tablespaces.
B. Indexes inherit the DEFERRED or IMMEDIATE segment creation attribute from their parent table.
C. It is the default behavior for tables and indexes.
D. Sessions may dynamically switch back and forth from DEFERRED to IMMEDIATE segment creation.
E. It is supported for SYS-owned tables contained in locally managed tablespaces.

Answer: B,C,D

Explanation:
A .False. IOTs require immediate segment creation.
B .False. SYS-owned tables don't use deferred creation.
C .True. Default since 11gR2, continued in 23ai.
D .True. Indexes inherit this attribute unless overridden.
E .True. Sessions can alter this via DEFERRED_SEGMENT_CREATION.
