CLD-R: undeploying a network published shared variable (q#29, t#1)

[mzu]

Question 29 (practice test 1) asks:

Which of the following should be done to un-deploy a network published shared variable?

b. Un-deploy the library the variable is part of in the Project Explorer window
c. Select Tools»Distributed System Manager select the Shared variable library and remove process 

---

Correct answer given: "C".

"C" will certainly work. It seems to me, "B" will also work.

LabVIEW help states: "To undeploy a shared variable, right-click the owning project library for the shared variable and select Undeploy from the shortcut menu." (http://zone.ni.com/reference/en-XX/help/371361G-01/lvconcepts/ni_psp/ ) 

What am I missing here?

I would have thought 'b' simply because the menu path listed in the question is different than this article.

[quote]If you need to remove the shared variable from the network, you must explicitly undeploy the library the variable is part of in the Project Explorer window. You also can select Tools»Shared Variable»Variable Manager to undeploy shared variables or entire project libraries of variables.[/quote]

Hello mzu, 

This is Andrew Brown, an Applications Engineer from National Instruments. I also agree that both B and C are viable methods of undeploying network shared variables. In the Shared Variable Lifetime section of Using the LabVIEW Shared Variable article, it mentions the two options as:

1. If you need to remove the shared variable from the network, you must explicitly undeploy the library the variable is part of in the Project Explorer window. The following is a screenshot of the process, with the options appearing when you right click on the library containing the network shared variable:

2. You also can select Tools»Shared Variable»Variable Manager to undeploy shared variables or entire project libraries of variables. In Labview 8.6 the Variable Manager has been replaced by the Distributed System Manager and can be found by selecting Tools»Distributed System Manager. The following is a screenshot of the Distributed System manager, again right clicking on the library containing the shared variable to present the options:

 

With both cases, you would be undeploying the library containing the network shared variable instead of the specific shared variable. Please let me know if you have additional questions about undeploying network shared variables.

Regards,

Andrew

The real question should be: Why is a platform-specific question on a certifcation exam in the first place?  Shared variables are not available on Mac or Linux platforms.

I don't think mzu had any questions about undeploying shared variables. I have a bit of time before I have to take the CLD-R. I think the real concern is that there are two right answers but only one is considered correct.

My real concern is, that even in 2024 the question and the solution are still unrevised in Emerson rebranded CLD-R-prep material: https://download.ni.com/evaluation/certification/cld-r/CLD-R%20Exam%20Prep.%20Guide%20%20Sample%20Ex...

Because the test is remote, I'd save all the studying for an hour before the test.  (Enough time to go through both practice tests.)  That way it will be fresh in your mind when you take the real thing.  It is very important for it to be fresh in your mind when you take it.

Are you responding to someone? The original post is from 2011, it is about a CLD-R question where 2 answers seem correct but only 1 is accepted as the "true" answer in the correction.

I was trying to hint at something about the practice questions vs the real test without actually saying it and getting into trouble.
