Question 37

On your Oracle 12c database, you invoked SQL *Loader to load data into the EMPLOYEES table in the HR schema by issuing the following command:
$> sqlldr hr/hr@pdb table=employees
Which two statements are true regarding the command? (Choose two.)

A. It succeeds with default settings if the EMPLOYEES table belonging to HR is already defined in the database.

B. It fails because no SQL *Loader data file location is specified.

C. It fails if the HR user does not have the CREATE ANY DIRECTORY privilege.

D. It fails because no SQL *Loader control file location is specified.

Correct Answer:AC
Note:
* SQL*Loader is invoked when you specify the sqlldr command and, optionally, parameters that establish session characteristics.

Question 38

You support Oracle Database 12c Oracle Database 11g, and Oracle Database log on the same server. All databases of all versions use Automatic Storage Management (ASM).
Which three statements are true about the ASM disk group compatibility attributes that are set for a disk group? (Choose three.)

A. The ASM compatibility attribute controls the format of the disk group metadata.

B. RDBMS compatibility together with the database version determines whether a database Instance can mount the ASM disk group.

C. The RDBMS compatibility setting allows only databases set to the same version as the compatibility value, to mount the ASM disk group.

D. The ASM compatibility attribute determines some of the ASM features that may be used by the Oracle disk group.

E. The ADVM compatibility attribute determines the ACFS features that may be used by the Oracle 10 g database.

Correct Answer:ABD
AD: The value for the disk group COMPATIBLE.ASM attribute determines the minimum software version for an Oracle ASM instance that can use the disk group. This setting also affects the format of the data structures for the Oracle ASM metadata on the disk.
B: The value for the disk group COMPATIBLE.RDBMS attribute determines the minimum COMPATIBLE database initialization parameter setting for any database instance that is allowed to use the disk group. Before advancing the COMPATIBLE.RDBMS attribute, ensure that the values for the COMPATIBLE initialization parameter for all of the databases that access the disk group are set to at least the value of the new setting for COMPATIBLE.RDBMS.
For example, if the COMPATIBLE initialization parameters of the databases are set to either 11.1 or 11.2, then COMPATIBLE.RDBMS can be set to any value between 10.1 and 11.1 inclusively.
Not E:
/The value for the disk group COMPATIBLE.ADVM attribute determines whether the disk group can contain Oracle ASM volumes. The value must be set to 11.2 or higher. Before setting this attribute, the COMPATIBLE.ASM value must be 11.2 or higher. Also, the Oracle ADVM volume drivers must be loaded in the supported environment.
/ You can create an Oracle ASM Dynamic Volume Manager (Oracle ADVM) volume in a disk group. The volume device associated with the dynamic volume can then be used to host an Oracle ACFS file system.
The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group.
Note:
* The disk group attributes that determine compatibility are COMPATIBLE.ASM, COMPATIBLE.RDBMS. and COMPATIBLE.ADVM. The COMPATIBLE.ASM and COMPATIBLE.RDBMS attribute settings determine the minimum Oracle Database software version numbers that a system can use for Oracle ASM and the database instance types respectively. For example, if the Oracle ASM compatibility setting is 11.2, and RDBMS compatibility is set to 11.1, then the Oracle ASM software version must be at least 11.2, and the Oracle Database client software version must be at least 11.1. The COMPATIBLE.ADVM attribute determines whether the Oracle ASM Dynamic Volume Manager feature can create an volume in a disk group.

Question 39

Which four actions are possible during an Online Data file Move operation? (Choose four.)

A. Creating and dropping tables in the data file being moved

B. Performing file shrink of the data file being moved

C. Querying tables in the data file being moved

D. Performing Block Media Recovery for a data block in the data file being moved

E. Flashing back the database

F. Executing DML statements on objects stored in the data file being moved

Correct Answer:ACEF
- You can now move On line Datafile without hove to stop Monoged Recovery and manually copy and rename Files. This can even be used to move Datafiles from or to ASM.
- New in Oracle Database 12c: FROM METAUNK. Physical Standby Database is in Active Data Guard Mode (opened READ ONLY and Managed Recovery is running):
It is now possible to online move a Datafile while Managed Recovery is running, ie. the Physical Standby Database is in Active Data Guard Mode. You con use this Command to move the Datafile
- A flashback operation does not relocate a moved data file to its previous location. If you move a data file online from one location to another and later flash back the database to a point in time before the move, then the Data file remains in the new location, but the contents of the Data file ore changed to the contents at the time specified in the flashback.

Question 40

You want to create a database with a block size other than the default 8 kilobytes (KB) by using the Database Configuration Assistant (DBCA).
Which option should you use?

A. Automatic Storage Management (ASM) for storage of data files

B. a file system for storage of data files

C. a Data Warehouse database template

D. a custom database template

Correct Answer:D

Question 41

You have a production Oracle 12c database running on a host.
You want to install and create databases across multiple new machines that do not have any Oracle database software installed. You also want the new databases to have the same directory structure and components as your existing 12c database.
The steps in random order:
1. Create directory structures similar to the production database on all new machines.
2. Create a response file for Oracle Universal Installer (OUI) with the same configurations as the production database.
3. Create a database clone template for the database.
4. Run the Database Configuration Assistant (DBCA) to create the database.
5. Run OUI in graphical mode on each machine.
6. Run OUI in silent mode using the OUI response file.
Identify the required steps in the correct sequence to achieve the requirement with minimal human intervention.

A. 1, 5, and 4

B. 3, 1, 5, and 6

C. 2, 3, 6, and 4

D. 2, 1, 6, and 4

E. 2, 3, 1, and 6

Correct Answer:E

Question 42

Your production database uses file system storage. You want to move storage to Oracle Automatic Storage Management (ASM).
How would you achieve this?

A. by using a transportable database

B. by using the Database Upgrade Assistant (DBUA)

C. by using Data Pump

D. by using RMAN

Correct Answer:D
