Answer:

Q6. Which three statements are true regarding the use of the Database Migration Assistant for Unicode (DMU)? 

A. A DBA can check specific tables with the DMU 

B. The database to be migrated must be opened read-only. 

C. The release of the database to be converted can be any release since 9.2.0.8. 

D. The DMUcan report columns that are too long in the converted characterset 

E. The DMUcan report columns that are not represented in the converted characterset 

Answer: A,D,E 

Explanation: A: In certain situations, you may want to exclude selected columns or tables from scanning or conversion steps of the migration process. 

D: Exceed column limit 

The cell data will not fit into a column after conversion. 

E: Need conversion 

The cell data needs to be converted, because its binary representation in the target 

character set is different than the representation in the current character set, but neither 

length limit issues nor invalid representation issues have been found. 

Q7. 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. 

Q8. Consider the following scenario for your database: 

Backup optimization is enabled in RMAN. 

The recovery window is set to seven days in RMAN. 

The most recent backup to disk for the tools tablespace was taken on March 1, 

2013. 

The tools tablespace is read-only since March 2, 2013. 

On March 15, 2013, you issue the RMAN command to back up the database to disk. 

Which statement is true about the backup of the tools tablespace? 

A. The RMAN backup fails because the tools tablespace is read-only. 

B. RMAN skips the backup of the tools tablespace because backup optimization is enabled. 

C. RMAN creates a backup of the tools tablespace because backup optimization is applicable only for the backups written to media. 

D. RMAN creates a backup of the tools tablespace because no backup of the tablespace exists within the seven-day recovery window. 

Answer:

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.
