Basic Proficiency Quiz - Answers

1. In the next VI, which will be the execution order?

a.

b.

c.

d.

2. The error cluster contains:

a. A number, a string and a Boolean

b. An array of numbers, Boolean and string

c. A number, a Boolean and an Enum

d. None of the previous options

3. Which VI will you use to read an image?

VIs and functions that perform read operations usually have glasses in the icon. Pencil means writing data.
Also, images are binary data and not text data, so the right choice is Read From Binary File, which is answer D.

a.

b.

c.

d.

4. Every DAQ VI is referenced by:

a. Refnum

b. Task

c. Waveform

d. Node

5. In the next VI, name the output data Type:

Input "y", thich is of type EXT (Extended Precision Floating-Point Numeric), is converted to I32. So, the divide
function gets DBL input and I32 input. In such situations, integer numbers are automatically converted to
floating-point numbers (this is indicated by the red coercion dot). The result is going to be of type DBL.

a. Extended
b. Double

c. I64

d. I32

6. Comparing I16 and U16, which statement is true?

a. The I16 starts at -32,536 and the U16 at 0

I16 starts at -32,768

b. The I16 starts at 0 and the U16 at -32,536

"I" means "signed integer" and "U" means "unsigned integer"

c. The I16 has 17 bits, one of them for the sign and the U16 has 16 bits

"16" means the number has 16 bits - one for sign, 15 for value

d. Both can represent the same amount of numbers

Both have 16 bits, so they can represent 2

16

values

7. What is the result for the next VI?

Arithmetic functions operate element-wise (Add function adds element at index 0 in first array to element at
index 0 in second array, elements at index 1 in both arrays and so on). If the arrays have different number of
elements, result has the size of the smaller array.

a. 1D-Array containing {80,40,20,10,-60}

b. 1D-Array containing {120,30,-60}

c. 1D-Array containing {120,30}

d. 2D-Array containing {80,20}{40,10,-60}

8. What is every VI composed of (multiple answers may apply)?

a. Front panel

b. For loops

c. Case structures

d. Block diagram

e. Stop button control

9. Which of these is used to display a brief description of a VI?

Context Help gives short descriptions. LabVIEW Help shows longer and more detailed descriptions.

a. Context Help

b. LabVIEW Help

c. Example Finder

d. None of them

10. Modularity is related to which concept?

a. Acquiring Help easily

b. Handling several Data Types with the same VI

c. Using SubVI’s into other VI’s

d.

Modifying any control or indicator depending on the application
