QUESTION 1
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 tablespacesin the database must be encrypted.
D.    Oracle Database Vault must be enabled.

Answer: B
Explanation:
Configuration encryption will use 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.
http://docs.oracle.com/cd/E25054_01/backup.1111/e10642/rcmbckad.htm#CEGEJABH
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 2
A database is running in archivelog 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?

A.    The backup succeeds only if all the tablespaces are locally managed.
B.    The backup succeeds only if the RMAN default device for backup is set to disk.
C.    The backup fails because you cannot specify section size for a compressed backup.
D.    The backup succeeds and only the used blocks are backed up with a maximum backup piece size of 1024 MB.

Answer: D

QUESTION 3
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?

A.    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
B.    Setting the target tablespace to read-only after the segments are moved
C.    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 T3S percent used
D.    Taking the target tablespace offline after the segments are moved
E.    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

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 4
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?

A.    RMAN recovery catalog
B.    RMAN Media Management Library
C.    Enterprise Manager Cloud Control
D.    Enterprise Manager Database Express
E.    Oracle Secure Backup

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.

B.    Flashback Database must be enabled.
C.    Fast Recovery Area must be enabled.
D.    The recyclebin must be enabled for the database.
E.    Undo retention guarantee must be enabled.

Why is it that only one update is listed by the Flashback Version Query?

A.    Supplemental logging is not enabled for the database.
B.    The undo data that existed for versions of rows before the change to the table structure is invalidated.
C.    The db_flash3ACK_reteni:on_target parameter is set to a lower value and the undo data pertaining to the first transaction is flushed out.
D.    Undo retention guarantee is not enabled.
E.    Flashback Data Archive is full after the first update statement.

Answer: B
Explanation:
Retrieves all the versions of the rows that exist between two points in time or two SCNs
Retrieves only committed data
Cannot be used to query external tables, temporary tables, fixed tables, or views
Can be used to create views
Cannot span DDL commands
Filters out segment shrink operations
