QUESTION 1
You issue commands in SQL*Plus as the Oracle owner, to enable multithreading for your UNIX-based Oracle 12c database:
CONNECT/AS SYSDBA
ALTER SYSTEMSETTHREADED__EXECUTION= TRUESCOPE=SPFILE;
SHUTDOWNIMMEDIATE
You then restart the instance and get an error:
STARTUP
ORA-01031:insufficientprivileges
Why does the startup command return the error shown?

A. because the threaded architecture requires exiting from sql*pIus and reconnectingwith sql*PIus / as sysdba before issuing a startup command
B. because the threaded architecture requires issuing a new connect / as sysdba from within sql*pIus before issuing a startup command
C. because the threaded architecture requires authentication using a password file before issuing a startup command
D. because the threaded architecture requires connecting to the instance via a listener before issuing a startup command
E. because the threaded architecture requires restarting the listener before issuing astartup command

Answer: C

QUESTION 2
Examine the output:
SQL > ARCHIVE LOGLIST
Database log modeArchive Mode
Automatic archivalEnabled
Archive DestinationUSE_DB_RECOVERY_FILE_DEST
Oldest online log sequence376
Next log sequence to archive378
Current log sequence378
Which three types of files are automatically placed in the fast recovery area?

A. Flashback data archives (FDA)
B. Archived redo log files
C. Control file autobackups
D. Server parameter file (SPFILE)
E. Recovery Manager (RMAN) backup pieces

Answer: B,C,E
Reference:http://docs.oracle.com/cd/E11882_01/backup.112/e10642/glossary.htm#BRADV 526

QUESTION 3
Examine the RMAN commands executed in your database:
RMAN>CONFIGUREDEFAULT DEVICE TYPE TO disk;
RMAN>CONFIGURE DEVICETYPE DISK BACKUP TYPE TO BACKUPSET;
RKAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
You issue the command:
RMAN> BACKUP DATABASE;
Which two statements are true about the command?

A. It performs a log switch.
B. It creates compressed backup sets by using binary compression by default.
C. It backs up only the used blocks in data files.
D. It backs up data files, the control file, and the server parameter file.
E. It creates a backup of only the control file whenever the database undergoes a structural change.

Answer: B,E

QUESTION 4
Examine the commands executed to monitor database operations:
$> conn sys/oracle@prod as sysdba
SQL> VAR eid NUMBER
SQL>EXEC :eid :=
DBMS_SQL_MONITOR.BEGlN_OPERATION(‘batch_job’,FORCED_TRACKING=>’Y’);
Which two statements are true?

A. Database operations will be monitored only when they consume a significant amount of resource.
B. Database operations for all sessions will be monitored.
C. Database operations will be monitored only if the STATISTICS_LEVEL parameter is set to TYPICAL and CONTROL_MANAGEMENT_PACK_ACCESS is set DIAGNISTIC + TUNING.
D. Only DML and DDL statements will be monitored for the session.
E. All subsequent statements in the session will be treated as one database operation and will be monitored.

Answer: C,E

Explanation: C: Setting the CONTROL_MANAGEMENT_PACK_ACCESS initialization parameter to DIAGNOSTIC+TUNING (default) enables monitoring of database operations. Real-Time SQL Monitoring is a feature of the Oracle Database Tuning Pack.
Note:
* The DBMS_SQL_MONITOR package provides information about Real-time SQL Monitoring and Real-time Database Operation Monitoring.
*(not B) BEGIN_OPERATION Function starts a composite database operation in the current session.
/ (E) FORCE_TRACKING – forces the composite database operation to be tracked when
the operation starts. You can also use the string variable ‘Y’.
/ (not A) NO_FORCE_TRACKING – the operation will be tracked only when it has consumed at least 5 seconds of CPU or I/O time. You can also use the string variable ‘N’.

QUESTION 5
Automatic Shared Memory Management (ASMm) is enabled for your database instance, but parameters for the managed components are not defined.
You execute this command:
SQL> ALTER SYSTEM SET DB_CACHE_SIZE = 100M;
Which statement is true?

A. The minimum size for the standard buffer cache is 100 MB.
B. The maximum size for the standard buffer cache is 100 MB.
C. The minimum space guaranteed in the buffer cache for any server process is 100 MB.
D. The maximum space in the buffer cache that can be released for dynamic distribution is 100 MB.
E. The minimum size for all buffer caches is 100 MB.
