Examine the table definition:

Which three statements are true concerning the use of the Valid Time Temporal feature for the EMPLOYEES table?

A. The valid time columns employee_time_start and employee_time_end are automatically created. 

B. The same statement may filter on both transaction time and valid temporal time by using the AS OF TIMESTAMP and PERIOD FOR clauses.

C. The valid time columns are not populated by the Oracle Server automatically.

D. The valid time columns are visible by default when the table is described. 

E. Setting the session valid time using DBMS_FLASHBACK_ARCHIVE.ENABLE_AT_VALID_TIME sets the visibility for data manipulation language (DML), data definition language (DDL), and queries performed by the session.

Answer: ABE

B. Maximum Idle time

C. Parallel server limit

D. CPU

E. Exadata I/O

F. Local file system I/O

Answer: CDE

Q3. To enable the Database Smart Flash Cache, you configure the following parameters:

DB_FLASH_CACHE_FILE = ‘/dev/flash_device_1’ , ‘/dev/flash_device_2’ 

DB_FLASH_CACHE_SIZE=64G

What is the result when you start up the database instance?

A. It results in an error because these parameter settings are invalid. 

B. One 64G flash cache file will be used. 

C. Two 64G flash cache files will be used. 

D. Two 32G flash cache files will be used. 

Answer: A

Q4. Your are the DBA supporting an Oracle 11g Release 2 database and wish to move a table containing several DATE, CHAR, VARCHAR2, and NUMBER data types, and the table’s indexes, to another tablespace.

Which technique will move the table and indexes while maintaining the highest level of availability to the application?

A. Oracle Data Pump.

B. An ALTER TABLE MOVE to move the table and ALTER INDEX REBUILD to move the indexes.

C. An ALTER TABLE MOVE to move the table and ALTER INDEX REBUILD ONLINE to move the indexes.

D. Online Table Redefinition.

E. Edition-Based Table Redefinition.

Answer: D

Q5. Which three statements are true about SQL plan directives?

A. They are tied to a specific statement or SQL ID. 

B. They instruct the maintenance job to collect missing statistics or perform dynamic sampling to generate a more optimal plan.

C. They are used to gather only missing statistics.

D. They are created for a query expression where statistics are missing or the cardinality estimates by the optimizer are incorrect.

E. They instruct the optimizer to create only column group statistics.

F. Improve plan accuracy by persisting both compilation and execution statistics in the SYSAUX tablespace.

Answer: BDF

Q6. Which two statements are true about the Oracle Direct Network File system (DNFS)?

A. It utilizes the OS file system cache.

B. A traditional NFS mount is not required when using Direct NFS.

C. Oracle Disk Manager can manage NFS on its own, without using the operating kernel NFS driver.

D. Direct NFS is available only in UNIX platforms.

E. Direct NFS can load-balance I/O traffic across multiple network adapters.

Answer: CE

Q7. Your multitenant container (CDB) containing three pluggable databases (PDBs) is running in ARCHIVELOG mode. You find that the SYSAUX tablespace is corrupted in the root container.

The steps to recover the tablespace are as follows:

1.Mount the CDB. 

2.Close all the PDBs.

3.Open the database.

4.Apply the archive redo logs.

5.Restore the data file.

6.Take the SYSAUX tablespace offline.

7.Place the SYSAUX tablespace online.

8.Open all the PDBs with RESETLOGS.

9.Open the database with RESETLOGS.

10.Execute the command SHUTDOWN ABORT.

Which option identifies the correct sequence to recover the SYSAUX tablespace?

A. 6, 5, 4, 7

B. 10, 1, 2, 5, 8

C. 10, 1, 2, 5, 4, 9, 8

D. 10, 1, 5, 8, 10

Answer: A

Q8. Which two statements are true about Oracle Managed Files (OMF)?

A. OMF cannot be used in a database that already has data files created with user- specified directions.

B. The file system directions that are specified by OMF parameters are created automatically.

C. OMF can be used with ASM disk groups, as well as with raw devices, for better file management.

D. OMF automatically creates unique file names for table spaces and control files.
