Which of the following functions assembles CLuster elements by their owned label

[SeanMcM]

Hi,

On the CLAD sample online exams a question appears as follows:

Which of the following functions assembles CLuster elements by their owned label

a bundle

b unbundle

c unbundle by name

d bundle by name

My question is:

Obviously the answer is a or d but d cannot assemble a cluster while a does not bundle them by their owned labels.

Any ideas?

Thanks,

Sean

The answer is (a) - which does assemble using the labels as shown here:

I don't agree. Bundle assembles elements only by the order in which you wire them. The labels are there in the cluster but the bundle does not care. The Bundle by Name is what I give as the correct answer.

So while working in one of my regular labs the lead lab-Tech was rambling on about trivia as he ussually does when he started explaining that palacene (sp? modeling clay) is higly resistive to acids and other caustic gasses. He goes on to mention that "we use it to seal up leaks in the tear-gas hood...". So i look him in the eye and tell him "Jay, God help me if I ever need to know what I learn from you!"

So why would I tell that story here?

After reading the Q and reply I could not help but think,

"God help me if I ever have to answer a question like that!"

PS I agree with Dennis. The only way to know what the real answer should be is to find out what the original questioner had in mind when they wrote that Q.

Thanks Dennis and Thoric,

I'm still inclined to favor Thoric's answer, because although it does not sort them by name one can still extract the name.

It's a pretty nebulous question.  I blame NI!

There's a whole pile more verty tricky ones like that and the worst thing is they don't give the answers!

e.g. where can you insert an indicator?

a. block diagram

b. front panel

c. both

d. neither

It has to be c, I hope, although you won't find an indicator on the functions panel you can create an indciator by right clicking on a function and create indicator. They're tricky!

Ben,

I totally agree but unfortunately in order to pass the exam I have to answer the questions that they pose and not argue the validity of the queation!

2 hours 9min to the exam!

After re-reading the question carefully, I think you might be right Dennis.

"Which of the following functions assembles Cluster elements by their owned label", not "including their owned label"

The only way to bundle by the label, of course, is to use a "bundle by label" and provide a template for the input cluster terminal. With a simple bundle function, as you say, you get a cluster which contain labels, but they haven't actually been bundled by label, instead they're bundled by the order in which they've been wired to the bundle function.

Then go with the answer from Dennis.

Thoric's reply is just too subtle for the the question writter to know that little piece of trivia.

Ben,

I'm going with Thoric's first answer, I think, it is not possible to assemble a cluster using bundle by name.

thanks for your help

You will if you use a merge VI which includes an indicator. I would say that the strict answer would be B but the correct answer would be C.

Both questions are phrased badly, like many of the others, and people have been vocal in complaining about this sort of thing.

As for the original question, I'm also assuming that whoever wrote the question was thinking of the BBN. The use of the term "assemble" is simply confusing.
