Question 2

Because of logical corruption of data in a table, you want to recover the table from an RMAN backup to a specified point in time. 
Examine the steps to recover this table from an RMAN backup:
  1. Determine which backup contains the table that needs to be recovered. 
  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. 
  4. Create a Data Pump export dump file that contains the recovered table on a target database. 
Identify the required steps in the correct order.


  1. 1, 4, 3
  2. 1, 2
  3. 1, 4, 3, 2
  4. 1, 2, 4
Correct answer: D
Explanation:
Because according to oracle PDFs if you run restore table ... auxiliary a impede and rename can be included. So there is no reason to make the import manually if it can be already included in step 2.  Reference: https://docs.oracle.com/database/121/BRADV/rcmresind.htm#BRADV689

Question 3

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?


  1. It is set to/u01/app/oracle/product:/12.1.0/db_1/log.
  2. It is set to /u01/app/oracle/admin/en12.1.0/adump.
  3. It is set to /u01/app/oracle.
  4. It is set to /u01/app/oracle/flash_recovery_area.
Correct answer: C
Explanation:
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. Reference:http://docs.oracle.com/cd/B28359_01/server.111/b28310/diag001.htm#ADMIN11008

Question 4

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?


  1. Create both jobs by using Scheduler raised events.
  2. Create both jobs using application raised events.
  3. Create one job to rebuild indexes using application raised events and another job to perform bulk load using Scheduler raised events.
  4. 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
Explanation:
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.  References:https://docs.oracle.com/cd/B28359_01/server.111/b28310/scheduse008.htm#CHDIAJEBhttps://docs.oracle.com/cd/E18283_01/server.112/e17120/scheduse005.htm#CIABIEJA

Question 5

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?


  1. C##admin can create and select any table, and grant the c##role1 role to users only in the root container.
  2. B_admin can create and select any table in both the root container and Hr_pdb.
  3. c##admin can create and select any table in the root container and all the PDBs.
  4. B_admin can create and select any table only in hr_pdb.
  5. The grant c##role1 to b_admin command returns an error because container should be set to ALL.
Correct answer: CD



Question 6

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?


  1. It executes successfully and the c##role1 role is revoked from the c##a_admin user only in the root container.
  2. It fails and reports an error because the container=all clause is not used.
  3. It executes successfully and the c##rocl1 role is revoked from the c##a_admin user in the root database and all the PDBs.
  4. It fails and reports an error because the comtainer=current clause is not used.
Correct answer: B
Explanation:
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.
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 7

Examine the RMAN command:
RMAN> CONFIGURE ENCRYPTION FOR DATABASE ON; 
RMAN> BACKUP DATABASE PLUS ARCHIVELOG; 
Which prerequisite must be met before accomplishing the backup?


  1. The password for the encryption must be set up.
  2. Oracle wallet for the encryption must be set up.
  3. All the tablespaces in the database must be encrypted.
  4. Oracle Database Vault must be enabled.
Correct answer: B
Explanation:
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.Reference:http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmbckad.htm#CEGEJABH

Question 8

A database is running in archive log mode. The database contains locally managed tablespaces. Examine the RMAN command:
RMAN> BACKUP 
AS COMPRESSED BACKUPSET 
SECTION SIZE 1024M 
DATABASE; 
Which statement is true about the execution of the command?


  1. The backup succeeds only if all the tablespaces are locally managed.
  2. The backup succeeds only if the RMAN default device for backup is set to disk.
  3. The backup fails because you cannot specify section size for a compressed backup.
  4. The backup succeeds and only the used blocks are backed up with a maximum backup piece size of 1024 MB.
Correct answer: D
Explanation:
COMPRESSED enables binary compression. RMAN compresses the data written into the backup set to reduce the overall size of the backup set. All backups that create backup sets can create compressed backup sets. Restoring compressed backup sets is no different from restoring uncompressed backup sets. RMAN applies a binary compression algorithm as it writes data to backup sets. This compression is similar to the compression provided by many media manager vendors. When backing up to a locally attached tape device, compression provided by the media management vendor is usually preferable to the binary compression provided by BACKUP AS COMPRESSED BACKUPSET. Therefore, use uncompressed backup sets and turn on the compression provided by the media management vendor when backing up to locally attached tape devices. You should not use RMAN binary compression andmedia manager compression together. Some CPU overhead is associated with compressing backup sets. If the target database is running at or near its maximum load, then you may find the overhead unacceptable. In most other circumstances, compressing backup sets saves enough disk space to be worth the CPU overhead. SECTION SIZE sizeSpec  Specifies the size of each backup section produced during a data file backup. By setting this parameter, RMAN can create a multisection backup. In a multisection backup, RMAN creates a backup piece that contains one file section, which is a contiguous range of blocks in a file. All sections of a multisection backup are the same size. You can create a multisection backup for a data file, but not a data file copy. File sections enable RMAN to create multiple steps for the backup of a single large data file. RMAN channels can process each step independently and in parallel, with each channel producing one section of a multisection backup set. If you specify a section size that is larger than the size of the file, then RMAN does not use multisection backup for the file. If you specify a small section size that would produce more than 256 sections, then RMAN increases the section size to a value that results in exactly 256 sections. Depending on where you specify this parameter in the RMAN syntax, you can specify different section sizes for different files in the same backup job. Note: You cannot use SECTION SIZE with MAXPIECESIZE or with INCREMENTAL LEVEL 1.

Question 9

In your database, the tbs percent used parameter is set to 60 and the tbs percent free parameter is set to 20. 
Which two storage-tiering actions might be automated when using Information Lifecycle Management (ILM) to automate data movement?


  1. The movement of all segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds tbs percent used
  2. Setting the target tablespace to read-only after the segments are moved
  3. The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS percent used
  4. Taking the target tablespace offline after the segments are moved
  5. The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds tbs percent used
Correct answer: BC
Explanation:
The threshold for activating tiering policies is based on two parameters:TBS PERCENT USED TBS PERCENT FREE Both values can be controlled by the DBMS_ILM_ADMIN package. TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively. Hence, whenever the source tablespace’s usage percentage goes beyond 85 percent, any tiering policy specified on its objects will be executed and objects will be moved to the target tablespace until the source tablespace becomes at least 25 percent free. Note that it is possible to add a custom condition to tiering policies to enable movement of data based on conditions other than how full the tablespace is. In addition, the READ ONLY option must be explicitly specified for the target tablespace.

Question 10

You want to consolidate backup information and centrally manage backup and recovery scripts for multiple databases running in your organization. 
Which two backup solutions can be used?


  1. RMAN recovery catalog
  2. RMAN Media Management Library
  3. Enterprise Manager Cloud Control
  4. Enterprise Manager Database Express
  5. Oracle Secure Backup
Correct answer: AC
Explanation:
Enterprise Manager allows a centralized control of database backups. It is possible to set up and schedule RMAN backups for all the databases in a large company, use a consistent backup strategy, and refer to all past RMAN output logs at any time, since they are stored in the Enterprise Manager Cloud Control repository. There is no need to use a central RMAN catalog, because information about the backups is centrally available from Enterprise Manager. And with the group backup feature new to Enterprise Manager Cloud Control 12c, it can be even faster to set up RMAN backups for all the databases-even if there are thousands-that are part of an Enterprise Manager group. References:http://www.oracle.com/technetwork/articles/oem/havewala-rman-em12c-2104270.html
