Which statement is true about the execution of the command? 

A. It returns an error because there isno level 0 backup available for new data files.

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.

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 

Q27. Which two statements are true about unified auditing? 

A. A unified audit trail captures audit information from unified audit policies and audit settings. 

B. Unified auditing is enabled by executing make-fins_rdbms.mk uniaud_onioracle ORACLE_HOME=SORACLE_HOME. 

C. Audit records are created for all users except sys. 

D. Audit records are created only for the DML and DDL operations performed on database objects.

Q29. 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? 

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 bythe 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. 

Answer: A,B,E 

Explanation: 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 CreateTable 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 thecase of which, the Period For clause would be creating them internally. 

E: ENABLE_AT_VALID_TIME Procedure 

This procedure enables session level valid time flashback.

2.Mount the database. 

3.Restore the data files by using the RMAN restore database command. 

4.Open the database with the resetlogs option. 

5.Recover the data files by using the RMAN recover using backup controlfile command. 

6.
