Q4. The CATDBI2c database contains an Oracle Database 12ccatalog schema owned by the rc12c user. 

The CATDB11database contains an Oracle Database l1g catalog schema owned by the RCII user. 

A database with DBID=1423241 is registered in the CATDB11catalog. Both the recovery catalog databases are open. 

In the CATDB12c database, you execute the commands: 

Srman 

RMAN> CONNECT CATALOG rc12c/pass12c8catdbI2c 

RMAN> IMPOST CATALOG rc1l/pwdcatl19catdbl1DBID=I423241; 

What is the outcome of the import? 

A. It fails because the target database and recovery catalog database are of different versions. 

B. It succeeds and all global scripts in the sc:: catalog that have the same name as existing global scripts in the RC12C catalog are automatically renamed. 

C. It succeeds but the database is not automatically registered in the Rc12c catalog. 

D. It fails because RMAN is not connected to thetarget database with DBID=1423241.

A. A PDB opened in restricted mode allows only local users to connect. 

B. When a CDB is open in restricted mode, PDBs must also be opened in restricted mode. 

C. When a CDB is in mount state, PDBs are automatically placed in mount state. 

D. All PDBs must be shut down before shutting down a CDB instance. 

E. When a CDB instance is started, PDBs can be placed in open state by using database triggers or by executing the alter pluggable database command. 

Answer: D,E

Q9. 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 

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? 

A. Re-enable redaction policies that use FULL data redaction. 

B. Re-create redaction policies that use FULL data redaction. 

C. Re-connect the sessions that access objects with redaction policies defined on them. 

D. Flush the shared pool. 

E. Restart the database instance. 

Answer:

Explanation: About Altering the Default Full Data Redaction Value You can alter the default displayed values for full Data Redaction polices. By default, 0 is the redacted value when Oracle Database performs full redaction (DBMS_REDACT.FULL) on a column of the NUMBER data type. If you want to change it to another value (for example, 7), then you can run the DBMS_REDACT.UPDATE_FULL_REDACTION_VALUES procedure to modify this value. The modification applies to all of the Data Redaction policies in the current database instance. After you modify a value, you must restart the database for it to take effect. 

Q10. Examine the initialization parameter that is set in the PFILE: 

DB_CREATE_FILE_DEST ='/u01/app/oracle/oradata/'

B. The files created for both the root and seed databases use Oracle Managed Files (OMF). 

C. It creates a multitenant container database with the root and seed databases opened and one PDB mounted. 

D. It sets the users tablespace as the default for both the root and seed databases. 

E. undotbs1is used as the undo tablespace for both the root and seed databases. 

F. It creates a multitenant container database with the root database opened and the seed database mounted.
