문제1
You want to migrate your Oracle 11g database as a pluggable database (PDB) in a multitenant container database (CDB).
The following are the possible steps to accomplish this task:
1. Place all the user-defined tablespace in read-only mode on the source database.
2. Upgrade the source database to a 12c version.
3. Create a new PDB in the target container database.
4. Perform a full transportable export on the source database with the VERSION parameter set to 12 using the expdp utility.
5. Copy the associated data files and export the dump file to the desired location in the target database.
6. Invoke the Data Pump import utility on the new PDB database as a user with the DATAPUMP_IMP_FULL_DATABASE role and specify the full transportable import options.
7. Synchronize the PDB on the target container database by using the DBMS_PDS.SYNC_ODB function.
Identify the correct order of the required steps.

Your database is running on the host OUSERVER. You back up your database regularly using RMAN and the backups are cataloged in a recovery catalog. For testing purposes, you want to replicate your database to another host, OUSERVER1, with the same directory structure. So, you copy the backups to the new host.
What must you do to make the database operational in OUSERVER1?

문제9
After implementing full Oracle Data Redaction, you change the default value for the number data type as follows:
SQL> SELECT NUMBER_VALUE FROM REDACTION_VALUES_FOR_TYPE_FULL;
NUMBER_VALUE
-------------------------
0
SQL> EXEC DBMS_REDACT.UPDATE_FULL_REDACTI0N_VALUES(-1)
PL/SQL procedure successfully completed.
SQL> select number_value from redaction_values_for_type_full;
NUMBER VALUE
------------------------
-1
After changing the value, you notice that FULL redaction continues to redact numeric data with a zero.
What must you do to activate the new default value for numeric full redaction?

Your database is running in archivelog mode and a nightly backup of the database, along with an autobackup of the control file, is taken by using RMAN. Because of a media failure, the SPFILE and the control files are lost.
Examine the steps to restore the SPFILE and the control file to mount the database:
1. Set DBID of the target database in RMAN.
2. Start the database instance by using the STARTUP FORCE NOMOUNT command in RMAN.
3. Restore the control files from the backup.
4. Mount the database.
5. Restore the SPFILE from the autobackup.
6. Create a PFILE from the recovered SPFILE.
7. Restart the instance in NOMOUNT state.
Identify the required steps in the correct order.

In your database, there are tablespaces that were read-only when the last backup was taken. These tablespaces have not been made read/write since then. You want to perform an incomplete recovery on the database by using a backup control file.
What precaution must you take for the read-only tablespaces before performing an incomplete recovery?

You are administering a multitenant container database (CDB) cdb1 that is running in archivelog mode and contains pluggable databases (PDBs), pdb_1 and pdb_2.
While opening pdb_1, you get an error:
SQL> alter pluggable database pdb_1 open;
ORA-01157: cannot identify/lock data file 11-see DBWR trace file
ORA-01110:data file 11:'/u01/app/oracle/oradata/cdb1/pdb_1/example01.dbf' To repair the failure, you open an RMAN session for the target database CDB$ROOT. You execute the following as the first command:
RMAN>REPAIR FAILURE;
Which statement describes the consequence of the command?
