Oracle Oracle Database 1Z0-067 Questions & Answers

• Question 251:

  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

  Configuration encryption will used 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. CONFIGURE ENCRYPTION : You can use this command to persistently configure transparent encryption. You cannot persistently configure dual mode or password mode encryption. SET ENCRYPTION : You can use this command to configure dual mode or password mode encryption at the RMAN session level.

• Question 252:

  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 table and select any table privileges.

  You then execute the commands:

  SQL> GRANTc##role1 TO##Madmin CONTAINER=ALL;

  SQL>CONNsys/oracle@HR_PDB as sysdba

  SQL> GRANTc##role1TO b_admin CONTAINER=CURRENT;

  Which two statements are true?

  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

• Question 253:

  Examine the commands executed in the root container of your multitenant container database (CDB) that

  has multiple pluggable databases (PDBs):

  SQL> CREATE USER c##a_admin IDENTIFIED BY orcl123;

  SQL> CREATE ROLE c##role1 CONTAINER=ALL;

  SQL> GRANT CREATE VIEW TO C##roleI CONTAINER=ALL;

  SQL> GRANT c##role1 TO c##a_admin CONTAINER=ALL;

  SQL> REVOKE c##role1 FROM c##a_admin;

  What is the result of the revoke command?

  A. It executes successfully and the c##role1 role is revoked from the c##a_admin user only in the root container.

  B. It fails and reports an error because the container=all clause is not used.

  C. It executes successfully and the c##rocl1 role is revoked from the c##a_admin user in the root database and all the PDBs.

  D. It fails and reports an error because the comtainer=current clause is not used.

  Correct Answer: B

  SQL> REVOKE c##role1 FROM c##a_admin; REVOKE c##role1 FROM c##a_admin * ERROR at line 1: ORA - 01951: ROLE `C##ROLE1' not granted to `C##A_ADMIN' SQL> REVOKE c##role1 FROM c##a_admin CONTAINER=ALL; Revoke succeeded. SQL> This CREATE USER c##a_admin IDENTIFIED BY orcl123; will create common user event container is not specified.

• Question 254:

  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

  C. 2, 1, 3, 7, 6, 9, and 8

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

  Correct Answer: C

  Because the step 2 says that you perfom an expdp with the full clause and you don't need to create the

  tablespaces when you perform the impdp. FULL=yes will export tablespace definitions. So no need step 9.

• Question 255:

  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

  The bulk loader would be started in response to a file watcher scheduler event and the indexes would be rebuilt in response to an application event raised by the bulk loader. Your application can raise an event to notify the Scheduler to start a job. A job started in this way is referred to as an event-based job. The job can optionally retrieve the message content of the event.

• Question 256:

  A. The current online redo log file is missing.

  B. A data file belonging to a noncritical tablespace is missing.

  C. All the control files are missing.

  D. The database backup is older than the control file backup.

  E. All the data files are missing.

• Question 257:

  Which two are prerequisites for setting up Flashback Data Archive?

  A. Fast Recovery Area should be defined.

  B. Undo retention guarantee should be enabled.

  C. Supplemental logging should be enabled.

  D. Automatic Undo Management should be enabled.

  E. All users using Flashback Data Archive should have unlimited quota on the Flashback Data Archive tablespace.

  F. The tablespace in which the Flashback Data Archive is created should have Automatic Segment Space Management (ASSM) enabled.

  Correct Answer: DF

  There are a number of restrictions for flashback archives: The tablespaces used for a flashback archive must use local extent management and automatic segment space management. The database must use automatic undo management. Reference: http://www.dba-oracle.com/t_11g_new_enabling_fdba.htm

• Question 258:

  The environmental variable oracle_Base is set to /u01/app/oracle and oracle_home is set to /u01/app/ oracle/product/12.1.0/db 1.

  You want to check the diagnostic files created as part of the Automatic Diagnostic Repository (ADR). Examine the initialization parameters set in your database.

  NAME TYPE VALUE

  audit_file_deststring/u01/app/oracle/admin/eml2rep/adump background_dump_deststring core_dump_deststring db_create_file_deststring db_recovery_file_deststring/u01/app/oracle/fast_recovery_area diagnostic_deststring

  What is the location of the ADR base?

  A. It is set to/u01/app/oracle/product:/12.1.0/db_1/log.

  B. It is set to /u01/app/oracle/admin/en12.1.0/adump.

  C. It is set to /u01/app/oracle.

  D. It is set to /u01/app/oracle/flash_recovery_area.

  Correct Answer: C

  The Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database.

  It is therefore available for problem diagnosis when the database is down. The ADR root directory is known

  as ADR base. Its location is set by the DIAGNOSTIC_DEST initialization parameter. If this parameter is

  omitted or left null, the database sets DIAGNOSTIC_DEST upon startup as follows:

  If environment variable ORACLE_BASE is set, DIAGNOSTIC_DEST is set to the directory designated by

  ORACLE_BASE.

  If environment variable ORACLE_BASE is not set, DIAGNOSTIC_DEST is set to ORACLE_HOME/log.

• Question 260:

  Which three statements are true about a job chain?

  A. It can contain a nested chain of jobs.

  B. It can be used to implement dependency-based scheduling.

  C. It cannot invoke the same program or nested chain in multiple steps in the chain.

  D. It cannot have more than one dependency.

  E. It can be executed using event-based or time-based schedules.

  Correct Answer: ABE

  Chains are the means by which you can implement dependency based scheduling, in which jobs are started depending on the outcomes of one or more previous jobs.
