• Question 63:

  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.

• Question 64:

  In your database, the tbs percent used parameter is set to 60 and the tbs percent free parameter is set to

  20.

  Which two storage-tiering actions might be automated when using Information Lifecycle Management (ILM) to automate data movement? (Choose two.)

  A. The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds tbs percent used

  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

• Question 65:

  You want to consolidate backup information and centrally manage backup and recovery scripts for multiple databases running in your organization.

  Which two backup solutions can be used? (Choose two.)

  A. RMAN recovery catalog

  B. RMAN Media Management Library

  C. Enterprise Manager Cloud Control

  D. Enterprise Manager Database Express E. Oracle Secure Backup

  Correct Answer: AC

• Question 66:

  A database is running in archivelog mode. The database contains locally managed tablespaces. Examine the RMAN command:

  RMAN> BACKUP AS COMPRESSED BACKUPSET SECTION SIZE 1024M DATABASE;

  Which statement is true about the execution of the command?

  A. The backup succeeds only if all the tablespaces are locally managed.

  B. The backup succeeds only if the RMAN default device for backup is set to disk.

  C. The backup fails because you cannot specify section size for a compressed backup.

  D. The backup succeeds and only the used blocks are backed up with a maximum backup piece size of 1024 MB.

  Correct Answer: D

• Question 67:

  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

  Reference: 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. http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmbckad.htm#CEGEJABH

• Question 68:

  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:

  1.

  Create a PDB named EMP_PDB1.

  2.

  Export the HR_PDB1 PDB by using the FULL clause.

  3.

  Open the EMP_PDB1 PDB.

  4.

  Mount the EMP_PDB1 PDB.

  5.

  Synchronize the EMP_PDB1 PDB in restricted mode.

  6.

  Copy the dump file to the Data Pump directory.

  7.

  Create a Data Pump directory in the EMP_PDB1 PDB.

  8.

  Import data into EMP_PDB1 with the FULL and REMAP clauses.

  9.

  Create the same tablespaces in EMP_PDB1 as in HR_PDB1 for new local user objects.

  Identify the required steps in the correct order.

  A. 2, 1, 3, 7, 6, and 8

  B. 2, 1, 4, 5, 3, 7, 6, 9, and 8

  D. 2, 1, 3, 5, 7, 6, and 8

  Correct Answer: C

• Question 69:

  You wish to create jobs to satisfy these requirements:

  1.

  Automatically bulk load data from a flat file.

  2.

  Rebuild indexes on the SALES table after completion of the bulk load.

  How would you create these jobs?

  A. Create both jobs by using Scheduler raised events.

  B. Create both jobs using application raised events.

  C. Create one job to rebuild indexes using application raised events and another job to perform bulk load using Scheduler raised events.

  D. Create one job to rebuild indexes using Scheduler raised events and another job to perform bulk load by using events raised by the application.

  Correct Answer: C

• Question 70:

  Your Oracle 12c multitenant container database (CDB) contains multiple pluggable databases (PDBs). In the PDB HR_PDB, the common user C##ADMIN and the local user B_ADMIN have only the CONNECT privilege.

  You create a common role C##ROLE1 with the CREATE ANY TABLE and SELECT ANY TABLE privileges.

  You then execute the commands:

  

  Which two statements are true? (Choose two.)

  A. C##ADMIN can create and select any table, and grant the C##ROLE1 role to users only in the root container.

  B. B_ADMIN can create and select any table in both the root container and HR_PDB.

  C. C##ADMIN can create and select any table in the root container and all the PDBs.

  D. B_ADMIN can create and select any table only in HR_PDB.

  E. The GRANT c##role1 TO b_admin command returns an error because CONTAINER should be set to ALL.

  Correct Answer: CD
