Q1. Which three statements are true about unplugging a pluggable database (PDB)?
A. The PDB must be open in read only mode.
B. The PDB must be dosed.
C. The unplugged PDB becomes a non-CDB.
D. The unplugged PDB can be plugged into the same multitenant container database (CDB)
E. The unplugged PDB can be plugged into another CDB.
F. The PDB data files are automatically removed from disk.
Answer: B,D,E
Explanation: B, not A: The PDB must be closed before unplugging it.
D: An unplugged PDB contains data dictionary tables, and some of the columns in these encode information in an endianness-sensitive way. There is no supported way to handle the conversion of such columns automatically. This means,quite simply, that an unplugged PDB cannot be moved across an endianness difference.
E (not F): To exploit the new unplug/plug paradigm for patching the Oracle version most effectively, the source and destination CDBs should share a filesystem so that thePDB’s datafiles can remain in place.

Q2. 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
D. backup.
E. An auxiliary instance must be started with the initialization parameter ENABLE_PLUGGABLE_DATABASE set to TRUE.
Answer: D,E
Q3. You execute the RMAN commands:
RMAN> BACKUP VALIDATE DATABASE; RMAN> RECOVER CORRUPTION LIST; Which task is performed by these commands?
A. Corrupted blocks, if any, are repaired in the backup created.
B. Only those data files that have corrupted blocks are backed up.
C. Corrupted blocks in the data files are checked and repaired before performing the database backup.
D. The database is checked for physicallycorrupt blocks and any corrupted blocks are repaired.
Answer: C
Q4. 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.
Answer: A,B
Q5. Which parameter must be set to which value toimplement automatic PGA memory management?
A. Set memory_target to zero.
B. Set STATISTICS_LEVEL to BASIC.
C. Set pga_aggregate_target to a nonzero value.
D. Set pga_aggregate_target and sga_target to the same value.
E. Set sgajtarget to zero.

Q6. For which two requirements would you use the Database Resource Manager?
A. limiting the CPU used per database call
B. specifying the maximum number of concurrent sessions allowed for a user
C. specifying the amount of private space a session can allocate in the shared pool of the SGA
D. limiting the degree of parallelism of operations performed by a user or group of users
E. specifying an idle time limit that applies to sessions that are idle and blocking other sessions
Answer: B,E
Q7. Examine the following set of RMAN commands:
RKAN> CONFIGURE CHANNEL del DEVICE TYPE DISK FORMAT ' /u02/backup/%U' ;
RKAN> RUN
{
ALLOCATE CHANNEL chl DEVICE TYPE DISK;
EXECUTE SCRIPT arc_backup;
}
Which statement is true about the RMAN run block execution?
A. The script is executed and both DC1 and chi channels are used for script execution.
B. The execution of the script fails because multiple channels cannot exist simultaneously.
C. The persistent configuration parameter, DC1, is overridden because a new channel is allocated in the RMAN run block.
D. The new channel, chi, is ignored because a channel has been configured already.
Answer: C
Q8. The following parameters are set for your Oracle 12c database instance:
OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES=FALSE OPTIMIZER_USE_SQL_PLAN_BASELINES=TRUE
You want to manage the SQL plan evolution task manually. Examine the following steps:
1.Setthe evolve task parameters.
2.Create the evolve task by using the DBMS_SPM.CREATE_EVOVLE_TASK function.
3.Implement the recommendations in the task by using the
DBMS_SPM.IMPLEMENT_EVOLVE_TASK function.
4.Execute the evolve task by using the DBMS_SPM.EXECUTE_EVOLVE_TASK function.
5.Report the task outcome by using the DBMS_SPM.REPORT_EVOLVE_TASK function.
Identify the correct sequence of steps.
A. 2, 4, 5
B. 2, 1, 4, 3, 5
C. 1, 2, 3, 4, 5
D. 1, 2, 4, 5
Answer: B
Q9. Which three tasks can be automatically performed by the Automatic Data Optimization feature of Information Lifecycle Management (ILM)?
A. tracking the most recent read time for a table segment in a user tablespace
B. tracking the most recent write time for a table segment in a user tablespace
C. tracking insert time by row for table rows
D. tracking the most recent write time for each block in a table segment
E. tracking the most recent read time for a table segment in the sysauxtablespace
F. tracking the most recent write time for a table segment in the sysauxtablespace
Answer: A,B,D
Q10. You want the execution of large database operations to suspend, and then resume, in the event of space allocation failures.
You set the value of the initialization parameter resumable_timeout to 3600.
Which two statements are true?
A. A resumable statement can be suspended and resumed only once during execution.
B. Data Manipulation Language (DML) operations are resumable, provided that they are not embedded in a PL/SQL block.
C. A suspended statement will report an error if no corrective action has taken place during a timeout period.
D. Before a statement executes in resumable mode, the alter session enable resumable statement must be issued in its session.
E. Suspending a statement automatically results in suspending a transaction and releasing all the resources held by the transaction.
Answer: A,D
