A. It is attached to a session.
B. It is owned by the user SYS.
C. A user can change the context of his or her application.
D. The PL/SQL package associated with the context must exist before the context is created.
E. The predefined attributes in the USERENV application context can be changed as per the requirements.
A. It executes successfully and displays 101 and 200000 values.
B. The ASSIGN_VAL function generates an error during compilation because nested tables cannot be
returned by functions.
C. The SELECT statement generates an error because the nested table has not been initialized in the ASSIGN_VAL function.
D. The ASSIGN_VAL function generates an error during compilation because the EXTEND method
be used with nested tables.
Examine the following settings for a session:
PLSQL_CODE_TYPE = NATIVE
PLSQL_OPTIMIZE_LEVEL = 3
Which statement would be true in this scenario?
A. The compiler would automatically inline subprograms.
B. The compiler would inline the code for external subroutines.
C. The compiler would inline the code even if the INLINE pragma is set to NO.
D. The compiler would not inline the code unless the INLINE pragma is set to YES.
The database instance was started up with the following initialization parameter values:
MEMORY_TARGET = 500M
RESULT_CACHE_MODE = FORCE
RESULT_CACHE_MAX_SIZE = 0
After the database startup, to enable the result cache, you issued the following command:
SQL> ALTER SYSTEM SET result_cache_max_size = 2M SCOPE = MEMORY;
Which is the effect of this command?
A. The query result cache is enabled and 2 MB of the memory target is allocated to the result cache.
B. The query result cache is enabled and 0.25% of the memory target is allocated to the result cache.
C. The command produces an error because the database instance is started up with the RESULT_CACHE_MAX_SIZE parameter set to 0.
D. The query result cache is not enabled because the database instance is started up with the RESULT_CACHE_MAX_SIZE parameter set to 0.
Examine the structure of the PRODUCTS table.
Name Null? Type

View the Exhibit and examine the PL/SQL block.
On execution, the PL/SQL block generates the following error:
ORA-01001: invalid cursor
What could be the reason?
A. Both the cursor variable arguments should have been passed in IN mode.
B. The contents of one cursor variable cannot be assigned to another cursor variable using the := operator.
C. The CLOSE statement closes both the cursor variables, therefore the last FETCH statement cannot execute.
D. The name of the cursor variables defined and the name of the cursor variables passed as arguments must be the same.
Identify three guidelines for the DBMS_ASSERT package. (Choose three.)
A. Prefix all calls to DBMS_ASSERT with the SYS schema name.
B. Embed DBMS_ASSERT verification routines inside the injectable string.
C. Escape single quotes when you use the ENQUOTE_LITERAL procedure.
D. Define and raise exceptions explicitly to handle DBMS_ASSERT exceptions.
E. Prefix all calls to DBMS_ASSERT with a schema name that owns the subprogram that uses the DBM _ASSERT package.
Which two statements are true about cursor variables? (Choose two.)
A. A cursor variable points to the current row in the result set of a multirow query stored in a work area.
B. A cursor variable is an explicitly named work area in which the results of different multirow queries
can be stored.
C. A cursor variable can be used only if a query is performed and its results are processed in the same subprogram.
D. A cursor variable can be used to perform a query in one subprogram, and process the results in a
Examine the code in the following PL/SQL block:
TYPE NumList IS TABLE OF INTEGER;
List1 NumList := NumList(11,22,33,44);
( ‘The last element# in List1 is ‘ || List1.LAST ||
‘ and total of elements is ‘||List1.COUNT);
Which two statements are true about the above code? (Choose two.)
A. LAST and COUNT give different values.
B. LAST and COUNT give the same values.
C. The four new elements that are added contain the value 33.
D. The four new elements that are added contain the value 44.
Which two statements are true about associative arrays and varrays? (Choose two.)

C. Both associative arrays and varrays must use sequential numbers as subscripts.
D. Both associative arrays and varrays can be used as column types in database tables.
You executed the following command to alter the session parameter:
SQL> ALTER SESSION SET PLSCOPE_SETTINGS = ‘IDENTIFIERS:ALL’;
Which two statements are true in this scenario? (Choose two.)
A. If the SYSAUX tablespace is unavailable, and you compile a program unit, PL/Scope does not collect
data for the compiled object.
B. All the identifiers declared in compiled program units before altering the parameter settings appear in
the *_IDENTIFIER static data dictionary views.
C. All the identifiers declared in compiled program units before altering the parameter settings do not appear
in the *_IDENTIFIER static data dictionary views.
D. If the SYSAUX tablespace is unavailable, and you compile a program unit, PL/Scope collects data for the compiled object and stores it in the SYSTEM tablespace.
Examine the following line of code that is part of a PL/SQL application:
stmt:=’SELECT session_id FROM sessions WHERE ‘ || p_where_stmt;
Identify a solution for preventing SQL injection in the above code.
A. Replace P_WHERE_STMT with a bind variable.
B. Do not use APIs that allow arbitrary query parameters to be exposed.
C. Use the RESTRICT_REFERENCES clause in the PL/SQL subprogram that contains the code.
D. Use DBMS_SQL to detect that the expression provided for P_WHERE_STMT is free from SQL injection.
