By default, members of the OSASM group can access Automatic Storage Management and RDBMS instances.

The primary group for the Oracle Grid Infrastructure and Oracle Database owners must be the Oracle Inventory group.

NO.160 Which three are located by using environment variables? (Choose three.)

the Optimal Flexible Architecture (OFA) compliant path to store Oracle software and configuration files.

the temporary disk space used by Oracle Installer during installation

the maximum number of database files that can be opened by a database instance

NO.161 Which three are true about transporting databases across platforms using Recovery Manager (RMAN) image copies? (Choose three.)

By default, the transported database will use Oracle Managed Files (OMF)

Data files can be converted on the destination system.

Data files can be converted on the source system.

A new DBID is automatically created for the transported database.

Databases can be transported between systems with different endian formats.

The password file is automatically converted by RMAN.

Explanation
A: If you do not provide a destination, then the DB_FILE_CREATE_DEST initialization parameter must be set in the target platform. RMAN restores the data files to the location specified by this parameter using new Oracle Managed File (OMF) names. BC: While creating the cross-platform backup to transport a database, you can convert the database either on the source database or the destination database. The benefit of performing the conversion on the destination database is that the processing overhead of the convert operation is offloaded from the source to the destination database.

NO.162 You execute the following piece of code with appropriate privileges: BEGIN DBMS_REDACT.ADD_POLICY ( END; object_schema object_name column_name policy_name function_type expression => ‘SCOTT’, => ‘EMP’, => ‘SAL’, => ‘SCOTT_EMP’, => DBMS_REDACT.FULL, => ‘SYS_CONTEXT (”SYS_SESSION_ROLES”,”MGR”) = ”FALSE”’); END; BEGIN DBMS_REDACT.ADD_POLICY ( object_schema object_name column_name policy_name function_type expression => ‘SCOTT’, => ‘EMP_VW’, => ‘SAL’, => ‘SCOTT_EMP_VW’, => DBMS_REDACT.NONE, => ‘SYS_CONTEXT (”SYS_SESSION_ROLES”,”MGR”) = ”FALSE”’); User SCOTT has been granted the CREATE SESSION privilege and the MGR role. Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table?

DataisredactedfortheEMP.SALcolumnonlyiftheSCOTTsessiondoesnothavetheMGR role set.

DataisredactedforEMP.SALcolumnonlyiftheSCOTTsessionhastheMGRroleset.

Data is never redacted for the EMP_VW.SAL column.

Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.

Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role set. Correct

NO.163 Which three are true about transporting databases across platforms using Recovery Manager (RMAN) image copies? (Choose three.)

By default, the transported database will use Oracle Managed Files (OMF)

Data files can be converted on the destination system.

Data files can be converted on the source system.

A new DBID is automatically created for the transported database.

Databases can be transported between systems with different endian formats.

The password file is automatically converted by RMAN.

NO.164 Which three actions are performed by the Oracle Preinstallation RPM, oracle-database-server-xxxx- preinstall, for Oracle Grid Infrastructure, where xxxx is the Oracle version and release? (Choose three.)

performing checks to ensure minimum configuration requirements for Oracle Grid Infrastructure are met

creating the oracleOS user

creating the OSDBA (dba) group

creating thte oraInventory (oinstall) group

creating the grid OS user

configuring the OS for Oracle Automatic Storage Management shared storage access

NO.165 Which two are true about creating RMAN backups for an Oracle container database? (Choose two.)

Tablespaces from different PDBs with identical names must be backed up by connecting RMAN separately to each PDB to back up the tablespaces.

The BACKUP DATABASEcommand will create a pluggable database (PDB) backup when RMAN is connected to a PDB.

SPFILEbackups can be created while connected to an application root PDB.

The BACKUP DATABASE PLUS ARCHIVELOGcommand will back up archive logs when RMAN is connected to a PDB.

The BACKUP PLUGGABLE DATABASEcommand can be used to back up CDB$ROOT.

NO.166 Examine the command for creating pluggable database PDB2 in container database CDB2.

Select three options, any one of which is required for it to execute successfully. (Choose three.)

Add the FILE_NAME_CONVERT clause to the statement and set the PDB_FILE_NAME_CONVERT parameter.

Add only the CREATE_FILE_DEST clause to the statement.

Set only the PDB_FILE_NAME_CONVERT parameter.

Set the PDB_FILE_NAME_CONVERT parameter and enable OMF.

Enable only OMF.

Add the FILE_NAME_CONVERT clause to the statement and enable Oracle Managed Files (OMF)

NO.167 How do you configure a CDB for local undo mode?

Open the CDB instance in upgrade mode. In cdb$root, execute alter database local undo on, and then restart the CDB instance.

Open the CDB in read-only mode. In cdb$root, execute alter database local undo on, and then change the CDB to read/write mode.

Open the CDB instance in restricted mode. In cdb$root, execute alter database local undo on. create an undo tablespace in each PDB, and then restart the CDB instance

Open the CDB instance in restricted mode. In cdb$root, drop the undo tablespace. Execute alter database local undo on in each PDB, and then restart the CDB instance.

Open the CDB instance in upgrade mode. In each PDB, execute alter database local undo on, create an undo tablespace, and then restart the CDB instance.
