Q1. In your multitenant container database (CDB) containing pluggable database (PDBs), the HR user executes the following commands to create and grant privileges on a procedure:

CREATE OR REPLACE PROCEDURE create_test_v (v_emp_id NUMBER, v_ename

VARCHAR2, v_SALARY NUMBER, v_dept_id NUMBER)

BEGIN

INSERT INTO hr.test VALUES (V_emp_id, V_ename, V_salary, V_dept_id); 

END;

/

GRANT EXECUTE ON CREATE_TEST TO john, jim, smith, king;

How can you prevent users having the EXECUTE privilege on the CREATE_TEST procedure from inserting values into tables on which they do not have any privileges?

A. Create the CREATE_TEST procedure with definer’s rights.

B. Grant the EXECUTE privilege to users with GRANT OPTION on the CREATE_TEST procedure.

C. Create the CREATE_TEST procedure with invoker’s rights.

D. Create the CREATE_TEST procedure as part of a package and grant users the EXECUTE privilege the package.

Q2. 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?

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.

Q3. Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB.  An RMAN backup exists for the database.

You issue the command to open ACCOUNTS_PDB and find that the USERDATA. DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupteD. 

What should you do before executing the commands to restore and recover the data file in ACCOUNTS_PDB?

A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in ACCOUNTS_PDB. 

B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE IMMEDIATE command. 

C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command. 

D. Take the USERDATA tablespace offline in ACCOUNTS_PDB.

Q4. Examine the current value for the following parameters in your database instance:

SGA_MAX_SIZE = 1024M 

SGA_TARGET = 700M 

DB_8K_CACHE_SIZE = 124M 

LOG_BUFFER = 200M

You issue the following command to increase the value of DB_8K_CACHE_SIZE: 

SQL> ALTER SYSTEM SET DB_8K_CACHE_SIZE=140M;

Which statement is true?

A. It fails because the DB_8K_CACHE_SIZE parameter cannot be changed dynamically.

B. It succeeds only if memory is available from the autotuned components if SGA. 

C. It fails because an increase in DB_8K_CACHE_SIZE cannot be accommodated within SGA_TARGET.

D. It fails because an increase in DB_8K_CACHE_SIZE cannot be accommodated within SGA_MAX_SIZE.

Q5. A new report process containing a complex query is written, with high impact on the database. You want to collect basic statistics about query, such as the level of parallelism, total database time, and the number of I/O requests.

For the database instance STATISTICS_LEVEL, the initialization parameter is set to 

TYPICAL and the CONTROL_MANAGEMENT_PACK_ACCESS parameter is set to DIAGNOSTIC+TUNING.

What should you do to accomplish this task?

A. Execute the query and view Active Session History (ASH) for information about the query.

B. Enable SQL trace for the query.

C. Create a database operation, execute the query, and use the DBMS_SQL_MONITOR.REPORT_SQL_MONITOR function to view the report.

D. Use the DBMS_APPLICATION_INFO.SET_SESSION_LONGOPS procedure to monitor query execution and view the information from the V$SESSION_LONGOPS view.

Q6. 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?

A. 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_EXD_FULL_DATABASE role.

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

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

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

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

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

Q7. 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.

A. Missing or stale histogram statistics

B. Undersized shared pool

C. High clustering factor for the indexes

D. High value for the DB_FILE_MULTIBLOCK_READ_COUNT parameter

E. Oversized buffer cache

Q8. You are required to migrate your 11.2.0.3 database as a pluggable database (PDB) to a multitenant container database (CDB).

The following are the possible steps to accomplish this task:

1.Place all the user-defined tablespace in read-only mode on the source database.

2.Upgrade the source database to a 12c version.

3.Create a new PDB in the target container database.

4.Perform a full transportable export on the source database with the VERSION parameter set to 12 using the expdp utility.

5.Copy the associated data files and export the dump file to the desired location in the target database.

6.Invoke the Data Pump import utility on the new PDB database as a user with the DATAPUMP_IMP_FULL_DATABASE role and specify the full transportable import options.

7. Synchronize the PDB on the target container database by using the DBMS_PDS.SYNC_ODB function.

Identify the correct order of the required steps.

A. 2, 1, 3, 4, 5, 6

B. 1, 3, 4, 5, 6, 7

C. 1, 4, 3, 5, 6, 7

C. Recover the table using Automated Tablespace Point In Time Recovery.

D. Recovery the table using Database Point In Time Recovery.
