Select the correct statement regarding BEQUEATH CURRENT_USER.

If a view references a PL/SQL function then BEQUEATH CURRENT_USER allows the function to execute with DBA privileges, regardless of the invoking user’s privileges.
The BEQUEATH CURRENT_USER clause allows invoker’s rights functions referenced in a view to execute with the privileges of the invoking user.
Any view calling a PL/SQL function with BEQUEATH CURRENT_USER in effect will execute with the privileges of the function owner.
With the BEQUEATH CURRENT_USER clause, a definer’s rights function referenced in a view executes with the privileges of the view owner, not the function owner.

The STUDENTS table with column LAST_NAME of data type VARCHAR2 exists in your database schema.

Examine this PL/SQL block:

Which two actions must you perform for this PL/SQL block to execute successfully?

Replace the FOR loop with FOR name_rec IN names_varray.FIRST .. names_varray.LAST LOOP.
Replace the L_NAME_TYPE declaration with TYPE 1_name_type IS VARRAY (25) OF SYS_REFCURSOR;
Add name_rec name_cur%ROWTYPE; at the end of the DECLARE section.
Replace the NAMES_VARRAY declaration with names_varray 1_name_type := 1_name_type ();
Replace the NAMES_VARRAY declaration with names_varray 1_name_type := null;
Add names_varray.EXTEND after the FOR …LOOP statement.

Correct answer: EF

Which two blocks of code execute successfully?

DECLARE
TYPE tab_type IS TABLE OF NUMBER;
my_tab tab_type;
BEGIN
my_tab (1) :=1;
END;
DECLARE
TYPE tab_type IS TABLE OF NUMBER;
my_tab tab_type := tab_type(2);
BEGIN
my_tab(1) :=55;
END;
DECLARE
TYPE tab_type IS TABLE OF NUMBER;
my_tab tab_type;

my_tab (1) := 55;
END;
DECLARE
TYPE tab_type IS TABLE OF NUMBER;
my_tab tab_type;
BEGIN
my_tab := tab_type ();
my_tab (1) := 55;
END;

my_tab.EXTEND (3, 2);
END;

Correct answer: BD

Examine this code:

Users of this function may set different date formats in their sessions.

Which two modifications must be made to allow the use of your session’s date format when outputting the cached result of this function?

Change the RETURN type to DATE.
Change AUTHID to CURRENT_USER.
Use the TO_CHAR function around SYSDATE, that is, 1_date := TO_CHAR (SYSDATE).
Change the data type of 1_date to DATE.
Set NLS_DATE_FORMAT to ‘DD-MM-YY’ at the instance level.
Set the RESULT_CACHE_MODE parameter to FORCE.

Correct answer: DF

Which statement is true about internal and external LOBs?

An external LOB can be loaded into an internal LOB variable using the DBMS_LOB package.
A NOEXIST_DIRECTORY exception can be raised when using internal and external LOBs.
Internal and external LOBs can be written using DBMS_LOB.
After an exception transfers program control outside a PL/SQL block, all references to open external LOBs are lost.
When using DBMS_LOB.INSTR for internal and external LOBs, DBMS_LOB.OPEN should be called for each LOB.
