You want to export the pluggable database (PDB) HR_PDB1 from the multitenant container database (CDB) CDB1 and import it into the CDB2 CDB as the EMP_PDB1 PDB.
Examine the list of possible steps required to perform the task:
Create a PDB named EMP_PDB1.
Export the HR_PDB1 PDB by using the FULL clause.
Open the EMP_PDB1 PDB.
Mount the EMP_PDB1 PDB.
Synchronize the EMP_PDB1 PDB in restricted mode.
Copy the dump file to the Data Pump directory.
Create a Data Pump directory in the EMP_PDB1 PDB.
Import data into EMP_PDB1 with the FULL and REMAP clauses.
Create the same tablespaces in EMP_PDB1 as in HR_PDB1 for new local user objects.
Identify the required steps in the correct order.

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> 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?
A. It executes successfully and the c##role1 role is revoked from the c##a_admin user only in the root container.
B. It fails and reports an error because the container=all clause is not used.
C. It executes successfully and the c##rocl1 role is revoked from the c##a_admin user in the root database and all the PDBs.
D. It fails and reports an error because the container=current clause is not used.
Correct Answer: B
Examine the RMAN command:
RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON; RMAN> BACKUP DATABASE PLUS ARCHIVELOG;
Which prerequisite must be met before accomplishing the backup?
A. The password for the encryption must be set up.
B. Oracle wallet for the encryption must be set up.
C. All the tablespaces in the database must be encrypted.
D. Oracle Database Vault must be enabled.
Correct Answer: B
configuration encryption will use by Transparent encryption, For transparent encryption, you will need to create a wallet, and it must be open. Transparent encryption will then occur automatically after you have issued the CONFIGURE
ENCRYPTION FOR DATABASE ON or CONFIGURE ENCRYPTION FOR TABLESPACE ON command.

B. Setting the target tablespace to read-only after the segments are moved
C. The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds T3S percent used
D. Taking the target tablespace offline after the segments are moved
E. The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds tbs percent used
Correct Answer: BC
You want RMAN to make duplicate copies of data files when using the backup command.

You create a table with the period for clause to enable the use of the Temporal Validity feature of Oracle Database 12c.
Examine the table definition:
create table employees (empno number, salary number, deptid number, name varchar2(100), period for employee_time);
Which three statements are true concerning the use of the Valid Time Temporal feature for the EMPLOYEES table? (Choose three.)
A. The valid time columns employee_time_start and employee_time_end are automatically created.
B. The same statement may filter on both transaction time and valid temporal time by using the AS OF TIMESTAMP and PERIOD FOR clauses.
C. The valid time columns are not populated by the Oracle Server automatically.
D. The valid time columns are visible by default when the table is described.
E. Setting the session valid time using DBMS_FLASHBACK_ARCHIVE.ENABLE_AT_VALID_TIME sets the visibility for data manipulation language (DML), data definition language (DDL), and queries performed by the session.
Correct Answer: ABC
A: To implement Temporal Validity(TV), 12c offers the option to have two date columns in that table which is having TV enabled using the new clause Period For in the Create Table for the newly created tables or in the Alter Table for the existing ones. The columns that are used can be defined while creating the table itself and will be used in the Period For clause or you can skip having them in the table\’s definition in the case of which, the Period For clause would be creating them internally.
Which two statements are true when row-archival management is enabled? (Choose two.)
A. Visibility of the ORA_ARCHIVE_STATE column is controlled by the row archival visibility session parameter.
B. The ORA_ARCHIVE_STATE column is updated manually or by a program that can reference activity tracking columns, to indicate that a row is no longer considered active.
C. The row archival visibility session parameter defaults to all rows.
D. The ORA_ARCHIVE_STATE column is visible if it is referenced in the select list of a query.
E. The ORA_ARCHIVE_STATE column is updated automatically by the database based on activity tracking columns, to indicate that a row is no longer considered active.
Correct Answer: BD
