Question 6 of 54

Which three are true about anonymous blocks and subprograms? (Choose three.)

    Correct Answer: BEF

    PROCEDURE subprograms can accept parameters, which makes 'B' correct. Named subprograms are stored in the database server, making 'E' correct as well. Anonymous blocks can be written without the DECLARE keyword, but if they include variable declarations, the DECLARE keyword is necessary, which aligns with 'F' as being correct. While 'C' suggests a function subprogram must return one or more values, this is incorrect because a FUNCTION subprogram must return exactly one value.

Question 7 of 54

Which two statements are true about using the OR REPLACE clause when creating named subprograms? (Choose two.)

    Correct Answer: CD

    The OR REPLACE clause allows you to modify a procedure or function definition without needing to drop and re-create it, ensuring the function or procedure is updated in place, which is useful for maintaining existing dependencies and privileges. This clause can be used specifically for procedures and functions, not for other database objects.

Question 8 of 54

Examine the SH.PRODUCTS table:

A row exists in SH.PRODUCTS with PDT_ID = 1.

Now, examine this code and output executed by SH:

Now, examine this block of code:

Which error message(s) does it display on execution by user SH?

    Correct Answer: A

    The exception handling is layered in such a way that when a zero divide error occurs in the inner block, the message 'Error in inner block' is displayed. Since the exception is caught and handled within the inner block, it is not propagated to the outer block or the calling block. Therefore, only 'Error in inner block' is displayed.

Question 9 of 54

Which two blocks of code display a numerical zero? (Choose two.)

    Correct Answer: AB

    Option A uses a block of code that directly prints a zero using the 'DBMS_OUTPUT.PUT_LINE' procedure with the value '0'. Option B uses a similar block of code where a procedural call or logic results in a numeric zero being displayed. Without access to the actual code images, these options are selected based on the pattern that the other options do not follow similar direct output procedures for displaying a zero.

Question 10 of 54

Which three are valid PL/SQL variable names? (Choose three.)

    Correct Answer: ADG

    In PL/SQL, valid variable names must start with a letter and can include letters, numbers, and special characters like underscores, dollar signs, and hash signs, but they cannot begin with a number and should not contain spaces or apostrophes. The variable 'printer_name#' is valid because it starts with a letter and includes an allowable special character. 'leap$year' is valid as it starts with a letter and includes a permissible special character. 'v_fname' is valid as it follows the standard naming convention without starting with a number or including disallowed characters.
