NEW QUESTION # 71
Which two statements are true about the UNLIMITED TABLESPACE system privilege and space quota?

  • A. It is overridden by a space quota specified for the user.
  • B. It allows a user to have unlimited space only in their default permanent tablespace.
  • C. It allows a role to have unlimited space in any tablespace in the database.
  • D. It allows a user to have unlimited space in any tablespace in the database.
  • E. By default, users have no quota on their default permanent tablespace.

Answer: A,D

Explanation:
A .True. Grants unlimited space across all tablespaces.
B .True. Explicit quotas override the privilege.
C .False. Not limited to default tablespace.
D .False. Roles can't have this privilege directly.
E .False. Default is zero quota unless specified.


NEW QUESTION # 72
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 all data in EMP with data from EMP.DAT.
  • B. It overwrites the data for Alan and adds data for Curl and Bob.
  • C. It generates a SQL script that it uses to load data from EMP.DAT to EMP.
  • D. It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
  • E. It appends data from EMP.DAT to EMP.

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 # 73
Which three statements are true about the tools used to configure Oracle Net Services?

  • A. Enterprise Manager Cloud Control can be used to centrally configure listeners on any managed database server.
  • B. The Oracle Net Configuration Assistant is only used when running the Oracle installer.
  • C. Oracle Net Manager can be used to centrally configure listeners on any database server target.
  • D. The lsnrctl utility requires a listener.ora file to exist before it is started.
  • E. Oracle Net Manager can be used to locally configure naming methods on a database server.
  • F. Enterprise Manager Cloud Control can be used to centrally configure net service names for any database server target.

Answer: A,E,F

Explanation:
A .False. Net Manager is local, not centralized.
B .False. NetCA can run standalone.
C .True. EMCC manages service names centrally.
D .True. EMCC configures listeners on managed targets.
E .False. lsnrctl starts a default listener if no listener.ora exists.
F .True. Net Manager configures local tnsnames.ora.


NEW QUESTION # 74
Which three tasks are performed by background processes in an Oracle database instance?

  • A. Writing dirty database block images from the buffer cache.
  • B. Reading database blocks into the buffer cache.
  • C. Reading database blocks into the buffer cache.
  • D. Creating dedicated server connections.
  • E. Registering services with Oracle Net listeners.
  • F. Writing redo to log files.

Answer: A,E,F

Explanation:
False. Server processes (foreground) read blocks into the buffer cache during user queries, not background processes.
Explanation:
Background processes manage core database operations. Let's break it down:
A : Creating dedicated server connections.
False. Dedicated server connections are created by the listener, not background processes. The listener hands off the connection to a server process (e.g., ora_s000), which isn't a background process.
B : Registering services with Oracle Net listeners.
True. The LREG process (Listener Registration, formerly PMON's role) registers services with listeners, using parameters like LOCAL_LISTENER.
Mechanics:LREG sends service details (e.g., orcl) to the listener every 60 seconds or on startup.
C : Writing redo to log files.
True. The LGWR (Log Writer) process writes redo entries from the redo log buffer to online redo log files, ensuring transaction durability.
Mechanics:Triggered by commits, log buffer fills, or checkpoints.
D : Writing dirty database block images from the buffer cache.
True. The DBWn (Database Writer) processes write modified (dirty) blocks from the buffer cache to data files, maintaining consistency.
Mechanics:Occurs at checkpoints or when free buffers are needed.


NEW QUESTION # 75
What are the three components of Oracle Database Automatic Maintenance Tasks?

  • A. A set of tasks that are started automatically at regular intervals to perform maintenance operations on the database.
  • B. The maintenance windows managed by Oracle Database Scheduler, which are predefined time intervals permitting scheduled tasks.
  • C. Oracle Database Resource Manager, which enables you to manage and configure system resources used by the Automatic Maintenance Tasks.
  • D. A packaging system that allows you to combine all error and failure logs to share with Oracle Support.
  • E. A diagnostic system that collects database error logs and details about database failures that can be found to diagnose complete file.
  • F. A database alert log that stores details about major database operations and errors, which is used to manage cluster performance.

Answer: A,B,C

Explanation:
A .False. Diagnostic collection is ADR, not AMT.
B .True. Resource Manager allocates resources to AMTs.
C .True. Scheduler defines maintenance windows.
D .False. Packaging is IPS/ADR, not AMT.
E .False. Alert log is separate from AMTs.
F .True. Tasks like stats collection are AMTs.
