QUESTION 19
Examine the following impdp command to import a database over the network from a pre-12c Oracle database (source):

Which three are prerequisites for successful execution of the command? (Choose three.)

The import operation must be performed by a user on the target database with the DATAPUMP_IMP_FULL_DATABASE role, and the database link must connect to a user on the source database with the DATAPUMP_EXP_FULL_DATABASE role.

All the user-defined tablespaces must be in read-only mode on the source database.

The export dump file must be created before starting the import on the target database.

The source and target databases must be running on the same platform with the same endianness.

The path of data files on the target database must be the same as that on the source database.

The impdp operation must be performed by the same user that performed the expdp operation.

QUESTION 20
Your multitenant container database (CDB) contains three pluggable database (PDBs). You find that the control file is damaged. You plan to use RMAN to recover the control file. There are no startup triggers associated with the PDBs.
Which three steps should you perform to recover the control file and make the database fully operational?

Recover and open the CDB in NORMAL mode.

Mount the CDB and then recover and open the database, with the RESETLOGS option.

Open all the pluggable databases.

Recover each pluggable database.

Start the database instance in the nomount stage and restore the control file from control file auto backup.

QUESTION 21

You issue the following statements:
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER EXCEPT SYS;
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER EXCEPT SYSTEM;
SQL> AUDIT POLICY ORA_DATABASE_PARAMETER EXCEPT SCOTT;
For which database users is the audit policy now active?

All users except SYS

All users except SCOTT

All users except SYSand SCOTT

All users except SYS, SYSTEM, and SCOTT

QUESTION 22
To implement Automatic Management (AMM), you set the following parameters:

When you try to start the database instance with these parameter settings, you receive the following error message:

Identify the reason the instance failed to start.

The PGA_AGGREGATE_TARGETparameter is set to zero.

The STATISTICS_LEVELparameter is set to BASIC.

Both the SGA_TARGETand MEMORY_TARGETparameters are set.

The SGA_MAX_SIZEand SGA_TARGETparameter values are not equal.

QUESTION 23
Which two statements are true about Oracle Managed Files (OMF)?

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

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

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

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

OMF may affect the location of the redo log files and archived log files.

QUESTION 24
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?

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

One 64G flash cache file will be used.

Two 64G flash cache files will be used.

QUESTION 26
A database is stored in an Automatic Storage Management (ASM) disk group, disk group, DGROUP1with SQL:

There is enough free space in the disk group for mirroring to be done.
What happens if the CONTROLLER1failure group becomes unavailable due to error or for maintenance?

Transactions and queries accessing database objects contained in any tablespace stored in DGROUP1 will fall.

Mirroring of allocation units will be done to ASM disks in the CONTROLLER2 failure group until the CONTROLLER1 for failure group is brought back online.

The data in the CONTROLLER1 failure group is copied to the controller2 failure group and rebalancing is initiated.

ASM does not mirror any data until the controller failure group is brought back online, and newly allocated primary allocation units (AU) are stored in the controller2 failure group, without mirroring.

Transactions accessing database objects contained in any tablespace stored in DGROUP1 will fail but queries will succeed.

QUESTION 27

SQL > VAR eid NUMBER
SQL > EXEC: eid:= DBMS_SQL_MONITOR.BEGIN_OPERATION (‘batch_job’,
FORCED_TRACKING => ‘Y’);
Which two statements are true? (Choose two.)

Database operations will be monitored only when they consume a significant amount of resources.

Database operations for all sessions will be monitored.

Database operations will be monitored only if the STATISTICS_LEVELparameter is set to TYPICAL and CONTROL_MANAGEMENT_PACK_ACCESSis set to DIAGNISTIC + TUNING.

Only DML and DDL statements will be monitored for the session.

All subsequent statements in the session will be treated as one database operation and will be monitored.

Which statement is true?

The ORACLE_BASE base parameter is not set.

The installation is being performed by the root user.

The operating system group that is specified should have the root user as its member.

The operating system group that is specified must have permission to write to the inventory directory.

QUESTION 33
You notice a high number of waits for the db file scattered read and db file sequential read events in the recent Automatic Database Diagnostic Monitor (ADDM) report. After further investigation, you find that queries are performing too many full table scans and indexes are not being used even though the filter columns are indexed.
Identify three possible reasons for this. (Choose three.)

Missing or stale histogram statistics

Undersized shared pool

High clustering factor for the indexes

High value for the DB_FILE_MULTIBLOCK_READ_COUNT parameter
