Because of logical corruption of data in a table, you want to recover the table from an RMAN backup to a specified point in time.
Examine the steps to recover this table from an RMAN backup:
1.Determine which backup contains the table that needs to be recovered.
2.Issue the recover table RMAN command with an auxiliary destination defined and the point in time specified.
3.Import the Data Pump export dump file into the auxiliary instance.
4.Create a Data Pump export dump file that contains the recovered table on a target database.
Identify the required steps in the correct order.

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?
SQL> SELECT NUMBER_VALUE FROM REDACTION_VALUES_FOR_TYPE_FULL;

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.

Examine the commands executed in the root container of your multitenant container database (CDB) that has multiple pluggable databases (PDBs):
SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123;
SQL> CREATE ROLE c##role1 CONTAINER=ALL;
SQL> GRANT CREATE VIEW TO C##roleI CONTAINER=ALL;
SQL> GRANT c##role1 TO c##a_admin CONTAINER=ALL;
SQL> REVOKE c##role1 FROM c##a_admin;
What is the result of the revoke command?
SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123;
