Appian Exam ACD100 Topic 3 Question 38 Discussion

Actual exam question for Appian's ACD100 exam

Question #: 38
Topic #: 3

In a rule, there is a variable named local!numberOfCustomers which will eventually change value.

You are tasked with creating a variable that captures the original value so that you can later compare the original and new value.

Which parameter settings should you use for your new variable?

ArefreshAlways:true

BrefreshOnReferencedVarChange: false

CrefreshOnReferencedVarChange: true

DrefreshOnVarChange:local!numberOfCustomers

Show Suggested Answer

Suggested Answer: B

Referencing another local variable creates a dependency between the two variables and ensures that the referenced variable is always evaluated first.

Hold up, is this a trick question? I bet the answer is none of the above, and we have to write our own custom code to do this. That's how they get you, you know.

Bah, who needs to keep track of the original value? Just use the new one, it's more exciting that way!

Ooh, I bet option A is the one! Refreshing the variable all the time sounds like the safest bet.

Hmm, I'm not sure. Option D seems to make the most sense to me, since it directly references the variable we're interested in.

Yeah, that could work. Let's go with option C.

That's a good point. Maybe we should go with option C instead.

I'm not sure, but I think refreshOnReferencedVarChange: true could also work for this scenario.

I disagree, I believe refreshOnVarChange:local!numberOfCustomers is the best option to capture the original value.

I think option C is the way to go. Refreshing the variable whenever the referenced variable changes is the best way to keep the original value up-to-date.
