Exam ACD101 Topic 4 Question 16 Discussion

Actual exam question for Appian's ACD101 exam
Question #: 16
Topic #: 4
Review the following expression rule:
union(ri!fruit, ri!vegetables)
The rule inputs are configured as text arrays.
What is the expected output?

Suggested Answer: C Vote an answer

The union() function in Appian combines the elements of two or more arrays into a single array, removing any duplicate values. Given that the rule inputs ri!fruit and ri!vegetables are configured as text arrays, the expected output of union(ri!fruit, ri!vegetables) would be an array containing all unique items from both ri!fruit and ri!vegetables, with any duplicates removed. This function is useful for combining lists without repetition, ensuring a clean, unique set of elements.
