Question 66

You enabled an audit policy by issuing the following statements:
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER BY SCOTT;
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER BY SYS, SYSTEM;
For which database users and for which executions is the audit policy now active? Select two.

A. SYS, SYSTEM
B. SCOTT
C. Only for successful executions
D. Only for failed executions
E. Both successful and failed executions

Correct Answer:AE
* The ORA_DATABASE_PARAMETER policy audits commonly used Oracle Database parameter settings. By default, this policy is not enabled.

Question 67

Which activity is audited by default and recorded in the operating system audit trail irrespective of whether or not database auditing is enabled?

A. execution of SQL statements by users connected with the SYSDBA privilege
B. creation of a fine-grained audit policy
C. configuration of unified auditing mode
D. usage of the AUDIT statement

Correct Answer:A

Question 68

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

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.

Correct Answer:CE
E: Performance is improved by load balancing across multiple network interfaces (if available). Note:
* To enable Direct NFS Client, you must replace the standard Oracle Disk Manager (ODM) library with one that supports Direct NFS Client.
Incorrect:
Not A: Direct NFS Client is capable of performing concurrent direct I/O, which bypasses any operating system level caches and eliminates any operating system write-ordering locks
Not B:
* To use Direct NFS Client, the NFS file systems must first be mounted and available over regular NFS mounts.
* Oracle Direct NFS (dNFS) is an optimized NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS storage devices (accessible over TCP/IP).
Not D: Direct NFS is provided as part of the database kernel, and is thus available on all supported database platforms - even those that don't support NFS natively, like Windows.
Note:
* Oracle Direct NFS (dNFS) is an optimized NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS storage devices (accessible over TCP/IP). Direct NFS is built directly into the database kernel - just like ASM which is mainly used when using DAS or SAN storage.
* Oracle Direct NFS (dNFS) is an internal I/O layer that provides faster access to large NFS files than traditional NFS clients.

Question 69

You performed an incremental level 0 backup of a database: RMAN > BACKUP INCREMENTAL LEVEL 0 DATABASE;
To enable block change tracking after the incremental level 0 backup, you issued this command: SQL > ALTER DATABASE ENABLE BLOCK CHANGE TRACKING USING FILE
‘ /mydir/rman_change_track.f’;
To perform an incremental level 1 cumulative backup, you issued this command: RMAN> BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE; Which three statements are true? (Choose three.)

A. Backup change tracking will sometimes reduce I/O performed during cumulative incremental backups.
B. The change tracking file must always be backed up when you perform a full database backup.
C. Block change tracking will always reduce I/O performed during cumulative incremental backups.
D. More than one database block may be read by an incremental backup for a change made to a single block.
E. The incremental level 1 backup that immediately follows the enabling of block change tracking will not read the change tracking file to discover changed blocks.

Correct Answer:ADE

Question 70

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.
