Q5. You have an OE_ACCESS_ORDERS_POLICY security policy implemented on the ORDERS table in the OE schema. The user sessions are able to access only the desired rows. The database administrator (DBA) uses the following command:

Which statement is true about user sessions that are connected currently?
A. The security policy remains in effect till the end of the current session.
B. The subsequent queries on the ORDERS table produce an ORA-01031: insufficient privileges error.
C. The subsequent queries on the ORDERS table within the current session are not controlled by the security policy.
D. The subsequent queries on the ORDERS table produce an ORA-28112: failed to execute policy function error.
Answer: C
Q6. View the Exhibit and examine the output.
Which statement is an inference from the output?
A. The class file is pinned into the Java pool.
B. The class file has been loaded into the shared library.
C. Java class methods in the Java class file have been published.
D. The loadjava command has been executed to load the Java source and class files.
Answer: D
Q7. Which two types of query results cannot be stored in the query result cache? (Choose two.)
A. subquery results
B. results of a query having the SYSDATE function
C. results of a query having the GROUP BY clause
D. results of a query having the DATE data type in the WHERE clause
Answer: A,B
Q8. The PLSQL_OPTIMIZE_LEVEL parameter is set to 2 for the session.
Examine the section of code given:
FUNCTION p2 (p boolean) return PLS_INTEGER IS ...
FUNCTION p2 (x PLS_INTEGER) return PLS_INTEGER IS
PRAGMA INLINE(p2, 'YES');
x := p2(true) + p2(3);
Which statement is true about the INLINE pragma procedure calls?
A. Only the call to the P2 function with BOOLEAN as the argument is inlined.
B. INLINE pragma affects both the functions named P2 and is called inline.
C. Only the call to the P2 function with PLS_INTEGER as the argument is inlined.
D. None of the functions are inlined because inlining is not supported for overloaded functions.
Answer: B
Q9. You issue this command to create a table called LOB_STORE:
CREATE TABLE lob_store
(lob_id NUMBER(3),
photo BLOB DEFAULT EMPTY_BLOB(),
cv CLOB DEFAULT NULL,
ext_file BFILE DEFAULT NULL)
/
What is the outcome?
A. The table is created successfully.
B. It generates an error because DEFAULT cannot be set to EMPTY_BLOB() during table creation.
C. It generates an error because DEFAULT cannot be set to null for a CLOB column during table creation.
D. It generates an error because DEFAULT cannot be set to null for a BFILE column during table creation.
Answer: A
Q10. Which two statements are true about the extproc process? (Choose two.)
A. It loads the dynamic library.
B. It is started by the server process.
C. It converts the C output back to PL/SQL.

C. They cannot be passed as parameters to PL/SQL subprograms.
D. They can be stored in a tablespace that is different from the tablespace that stores the table containing the LOB column.
Answer: B,D
Q12. Which two statements are true about the migration of BasicFile to the SecureFile format by using the DBMS_REDEFINITION package? (Choose two.)
A. It can be performed only on tables with a single LOB column.
B. It automatically creates an interim table during the migration process.
C. It allows the table that is migrated to be accessed throughout the migration process.
D. It requires free space that is at least equal to the space used by the table that is migrated.

Q13. Examine the following settings for a session:
PLSQL_CODE_TYPE = NATIVE
View the Exhibit and examine the PL/SQL code.
You compile the program with the following attributes:
SQL> ALTER PROCEDURE proc1 COMPILE PLSQL_OPTIMIZE_LEVEL = 1;
Which statement is true about the execution of the PROC1 procedure in this scenario?
A. The FUNC1 function would be called inline because PRAGMA INLINE forces a specific call to be inlined.
B. The FUNC1 function would be inlined because the value set for the PLSQL_CODE_TYPE parameter is set to NATIVE.
C. The FUNC1 function would be called inline irrespective of the value set for the PLSQL_OPTIMIZE_LEVEL parameter.
D. The FUNC1 function would not be called inline because the value for the PLSQL_OPTIMIZE_LEVEL parameter is set to a lower value.
Answer: D

/
Which statement is true about the outcome on executing the above PL/SQL block?
A. It executes successfully and displays the value 2.
B. It executes successfully and displays the value 0.
C. It generates an error because EXTEND cannot be used for varrays.
