CLA-R Sample Exam question 27

[Photon_Dan]

The question deals with single-element queues.  The "correct" answer suggest that "all of the above" are true.  One of the statements is "Single-element queues arre available on all LabVIEW systems".  Where are they in LabVIEW FPGA?

Another example of a poorly worked problem.  I don't exactly agree with A either.  I think what they were referring to with C is the Base, Professional, and Student versions.  I would have chosen B personally.

27. Which of the following are reasons for using single-element queues?
a. Single-element queues are more scalable than functional globals
b. Single-element queues can be used to produce atomic operations on data
c. Single-element queues are available on all LabVIEW systems
d. All of the above

[Photon_Dan]

Exactly!  I chose B, and I felt very confident about it.  I wasn't sure what measurement of scalability is being applied here.

I get rather annoyed at some of the questions, from all levels of certification. To quote myself from earlier in the year:

I was talking to some of the NI chaps at the recent summit saying I would rather retake the 4 hour exam and demonstrate that I can architect a program than an hour's worth of fatuous multiple guess questions.

If we were able to choose how we would like to recertify, it would mean less wasted time "revising" minutiae and unnecessarily specific terminology and more time being productive.

Our concerns have been heard.  Zaki, how about an update?

[Karin_Hellqvist]

I have no problem with A. I think you could say that it is more scalabe when it's faster and simplier to scale, which in this case it is.
