Q61. A complete database backup to media is taken for your database every day. Which three actions would you take to improve backup performance?
A. Set the backup_tape_io_slaves parameter to true.
B. Set the dbwr_io_slaves parameter to a nonzero value if synchronous I/O is in use.
C. Configure large pool if not already done.
D. Remove the rate parameter, if specified, in the allocate channel command.
E. Always use RMAN compression for tape backups ratherthan the compression provided by media manager.
F. Always use synchronous I/O for the database.
Q62. Examine the resources consumed by a database instance whose current Resource Manager plan is displayed.
SQL> SELECT name, active_sessions, queue_length, consumed_cpu_time, cpu_waits, cpu_wait_time FROM v$rsrc_consumer_group;
Which two statements are true?
A. An attempt to start a new session by a user belonging to DSS_QUERIES fails with an error.
B. An attempt to start a new session by a user belonging to OTHE_GROUPS fails withan error.
C. The CPU_WAIT_TIME column indicates the total time that sessions in the consumer group waited for the CPU due to resource management.
D. The CPU_WAIT_TIME column indicates the total time that sessions in the consumer group waited for the CPU due to I/O waits and latch or enqueue contention.
E. A user belonging to the DSS__QUERIES resource consumer group can create a new session but the session will be queued.

Q63. Your database instance is started using an SPFILE. You are connected to cdb$root, as a DBA. You issue:
SQL> ALTER SYSTEM SET STATISTICS_LEVEL=ALL SCOPE=BOTH;
Which two statements are true about the statistics level parameter?
A. It is immediately set to all in the SPFILE and the CDB instance.
B. It is immediately set to all in only those pluggable databases (PDBs) where the value is set to typical.
C. It is immediately set to all only for cd3Sroot.
D. It is immediately set to all in all PDBs where the statistics_level parameter is not set.
E. It is set to all for all PDBs only in the SPFILE.
Q64. You issue commands in SQL*Plus as the Oracle owner, to enable multithreading for your UNIX-based Oracle 12c database:
ALTER SYSTEMSETTHREADED__EXECUTION= TRUESCOPE=SPFILE;
You then restart the instance and get an error:
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
Q65. Examine the command to duplicate a database:
RMAN> DUPLICATE TARGET DATABASE TO cdb
PLUGGABLE DATABASE pdb1, pdb5;
Which two statements are true about the DUPLICATE command?
A. The SPFILE is copied along with the datafiles of the pluggable databases (PDBs). The root and the seed database in the container database (CDB) are also duplicated.
B. A backup of pdbi and pd35 must exist before executing the command.
C. The duplicate command first creates a backup, and then duplicates the PDBs by using the
E. An auxiliary instance must be started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.

B. All database listeners running from the database home are automatically added to the Oracle Restart configuration.
C. The srvct1 add database command must be used to add orcl1 and orcl2 to the Oracle Restartconfiguration.
