Demo Questions

Question 1

Your database is running in archivelog mode and a nightly backup of the database, along with an autobackup of the control file, is taken by using RMAN. Because of a media failure, the SPFILE and the control files are lost. 
Examine the steps to restore the SPFILE and the control file to mount the database:
  1. Set DBID of the target database in RMAN. 
  2. Start the database instance by using the startup force nomount command in RMAN. 
  3. Restore the control files from the backup. 
  4. Mount the database. 
  5. Restore the SPFILE from the autobackup. 
  6. Create a PFILE from the recovered SPFILE. 
  7. Restart the instance in nomount state. 
Identify the required steps in the correct order.


  1. 1, 2, 5, 3, 6, 4
  2. 1, 2, 3, 5, 6, 4
  3. 2, 1, 5, 7, 3, 4
  4. 2, 1, 5, 6, 7, 4, 3
Correct answer: C



Question 2

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 
------------------------- 
0 
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?


  1. Re-enable redaction policies that use FULL data redaction.
  2. Re-create redaction policies that use FULL data redaction.
  3. Re-connect the sessions that access objects with redaction policies defined on them.
  4. Flush the shared pool.
  5. Restart the database instance.
Correct answer: E
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.

Question 3

You want to create a guaranteed restore point for your database by executing the command:
SQL> CREATE RESTORE POINT dbrsp1 GUARANTEE FLASHBACK DATABASE; 
Identify two prerequisites for the successful execution of this command. (Choose two.)


  1. The database must be running in archivelog mode.
  2. Flashback Database must be enabled.
  3. Fast Recovery Area must be enabled.
  4. The recyclebin must be enabled for the database.
  5. Undo retention guarantee must be enabled.
  6. A database backup must be taken.
Correct answer: AC

Question 4

Your database has a table CUSTOMERS that contains the columns CUST_NAME, AMT_DUE, and OLD_STATUS. 
Examine the commands executed and their output:
  
Why is it that only one update is listed by the Flashback Version Query?


  1. Supplemental logging is not enabled for the database.
  2. The undo data that existed for versions of rows before the change to the table structure is invalidated.
  3. The DB_FLASHBACK_RETENTION_TARGET parameter is set to a lower value and the undo data pertaining to the first transaction is flushed out.
  4. Undo retention guarantee is not enabled.
  5. Flashback Data Archive is full after the first update statement.
Correct answer: B



Question 5

Which two methods can be used to add an Oracle 11g database to a multitenant container database (CDB) as a pluggable database (PDB)? (Choose two.)


  1. Use the DBMS_PDB package to plug the Oracle 11g database into the existing CDB as a PDB.
  2. Use the CREATE DATABASE ... ENABLE PLUGGABLE DATABASE statement to create a PDB by copying data files from PDB$SEED and use data pump to load data from the Oracle 11g database into the newly created PDB.
  3. Pre-create a PDB in CDB and use data pump to load data from the complete database export of the Oracle 11g database into the newly created PDB.
  4. Pre-create a PDB in CDB and use the NETWORK_LINK and PARALLEL parameters with data pump import to import data from the Oracle 11g database to the newly created PDB.
  5. Upgrade the Oracle 11g database to a 12c non-CDB and use the DBMS_PDB.DESCRIBE procedure to plug the database as a new PDB into the CDB.
Correct answer: DE



Question 6

In which three scenarios is media recovery required? (Choose three.)


  1. when a tablespace is accidentally dropped from a database
  2. when archived redo log files are lost
  3. when data files are lost
  4. when one of the online redo log members is corrupted
  5. when all control files are lost
Correct answer: ACE

Question 7

In the SPFILE, UNDO TABLESPACE is Set to UNDOTBS. 
You rename the undotbs undo tablespace:
ALTER TABLESPACE undotbs RENAME TO undotbs_old; 
Which statement is true?


  1. The tablespace will be renamed but the data file headers will not be updated.
  2. The statement will fail because you cannot rename an undo tablespace.
  3. The tablespace will be renamed and all the changes will be logged in the alert log.
  4. The tablespace will be renamed and a message written to the alert log indicating that you should change the corresponding initialization parameter.
  5. You must set the undo_tablespace parameter to some other tablespace name before renaming undotbs.
Correct answer: C



Question 8

Which two statements are true about dropping a pluggable database (PDB)? (Choose two.)


  1. A PDB must be in mount state or it must be unplugged.
  2. The data files associated with a PDB are automatically removed from disk.
  3. A dropped and unplugged PDB can be plugged back into the same multitenant container database (CDB) or other CDBs.
  4. A PDB must be in closed state.
  5. The backups associated with a PDB are removed.
  6. A PDB must have been opened at least once after creation.
Correct answer: AD

Question 9

On your Oracle 12c database, you invoke SQL*Loader to load data into the employees table in the hr schema by issuing the command:
S>sqlldrhr/hr@pdb table=employees 
Which two statements are true about the command? (Choose two.)


  1. It succeeds with default settings if the employees table exists in the hr schema.
  2. It fails because no SQL*Loader data file location is specified.
  3. It fails if the hr user does not have the create any directory privilege.
  4. It fails because no SQL*Loader control file location is specified.
  5. It succeeds and creates the employees table in the HR schema.
Correct answer: AD



Question 10

Which three RMAN persistent settings can be set for a database? (Choose three.)


  1. backup retention policy
  2. default backup device type
  3. default section size for backups
  4. default destinations for backups
  5. multiple backup device types for a single backup
