CLAD

Dear All
 
I continue my study to the CLAD exam tomorrow, and i have more 4 questions to ask you help.
 
The questions are in www.astrolusis.com/test4.pdf
 
I ask you special attention to questions 2 and 38 because they are about Error handling and the local NI office doens't know the answers !
 
Thank you again to all

Hello,

2. the most common case is B, but in some NI VIs D happens... What do they expect you to answer, honestly I don't know !
For me the way you should code is B appart for a few specific cases.

29. again... no idea of what they expect but the only one that seems sensible to me is A.

35. I don't understand that question, sorry !

38. I happened to see that in FTP VIs, the task was perform correctly but reterned a warning... than can happen, so C.

9. F is the correct answer, only III and IV will stop. The red stop condition is "stop if true" and when there is an error, "status" is true.


I hope someday, NI people who make these questions will read this as a feedback. Sometimes, questions are pointless or not clear at all... Anyway, don't worry too much about this online exam, during the actual one, questions are clearer 😉

If CLAD contains more diagram than text, it will be easier to understand.

Well, I took my CLAD this morning, and passed. Hope you did too Raulcord.
 
However, I'm sure that two questions on the exam didn't have a correct answer.
 
One asked how to debug a VI with a broken wire. All answers involved "running" the VI.
 
Another asked for a description of an indicator showing the result of a calculation with a timer in a loop. I thought that the indicator would count downwards, but all the answers had it counting upwards. I have re-created the offending vi as best as I can remember, and it does indeed count down.
 
I have emailed NI in the UK about this (with more details) and await their answer with interest!

Hi Rod

Thank you and congratulations to you.

I have passed to, but they are really strange questions that i never hear about !

I have some in my house (i remember, and take note after the exam), and i go make a file and send to this forum.

What you tell don't appear in my exam.

All the best

Raúl

Hi again Rod

I read again your message an i remember this question from my other test i failed.

The answer i think is somtehing like "Follow the description of error by double clicking in the broken arrow and after in the line of the error"

best regards

Hello Raulcord,
 
... and well done to you too.
 
For the question about the VI with the broken wires, one of the answers said that you woud see the error message popup, and that is what I answered, as the other answers needed you to run the vi with a probe, breakpoint or highlight execution, so were clealy wrong, but the answer I gave was [in my opinion] also wrong as you had to "run" the VI. A "broken arrow" was not in the answers. I presume that this was the expected answer.
 
 
The question about the timers was probably a typo in the question. It wanted to know the appearance of the output of a "format date/time" in a loop.  Outside the loop was a "get time in seconds" to which a value was added before passing it into the loop. Inside the loop, the result of a "get time in seconds" was subtracted from the value passed into the loop. The result of the subtraction was passed to a "format date/time"
 
The question asked what the output of the format date/time would look like.
 
Two of the answers had a clearly wrong format and so were rejected.
 
The other two answers both had the same format (I think slightly wrong, but that may be my memory) One of the values was one that would occur during running on the VI, the other would not.
 
BUT... all four answers were that the output time would be increasing, and I remain sure that the value would be decreasing (especially as a loop termination condition was the displayed value in seconds becoming less than zero!).
 
I selected the one with the better format and the value that would occur. Again, I guess this was the "correct" answer.
 
 
 
Rod.

Learn terminology and details about every Labview functions.
Also try the preparation exam available on this site.  I think you can try it multiple times.
