Topic #: 5

[All ACD101 Questions]

Review the following expression rule:

union(ri!fruit, ri!vegetables)

The rule inputs are configured as text arrays.

What is the expected output?

AAll items in ri!fruit followed by items in ri!vegetables, including duplicate values.

BOnly items that are in both ri!fruit and ri!vegetables.

CAll items in ri!fruit and ri!vegetables combined, with duplicates removed.

Show Suggested 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.

C makes sense to me too.

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.
