union(ri!fruit, ri!vegetables)

Show Suggested Answer Hide Answer
Suggested Answer: B

The best practice in Appian for passing values into an interface is to use named parameters, which is demonstrated by Option B. Named parameters make the code more readable and maintainable by clearly specifying which parameter each value is being passed to. In this case, the recordId and firstName parameters are clearly being assigned the values 1 and 'Kyle' respectively. Reference:

Hmm, this is a tricky one. I'm leaning towards B, since the question mentions the rule 'union', which might have a different behavior than a regular union operation.

I'm going with C. The union operation should remove any duplicate values, so the output should be a combined list of all items from both arrays, without duplicates.

I'm not sure about this one. The question talks about a 'rule', so I'm guessing the output might be different from a standard union operation. I'll have to think about it some more.

I think the answer is A. The union operation should combine the contents of the two arrays, even if there are duplicates.
