Question
Consider the following high-level solution diagram:
What activity should be used for implementing the Classification Loop, according to UiPath Best Practices?
A. While activity.
B. Do While activity.
C. For Each activity.
D. Parallel For Each activity.
Answer
Based on the high-level solution diagram provided and UiPath best practices, the For Each activity (Option C) should be used to implement the Classification Loop.
Explanation
The diagram shows an extract-classify-process data pattern. After extracting and digitizing the document, the process enters a “Classification Loop” to classify each document. The “no more items” decision after the loop indicates it will iterate through multiple items.
The For Each activity is the best practice and optimal choice for looping through a collection of items, like the extracted data from the document in this case. It allows defining a data type for the items and will automatically exit when all items have been processed.
While and Do While are condition-based loops better suited when the number of iterations is unknown. Parallel For Each enables parallel processing but adds complexity and is not necessary for a straightforward classification loop.
Therefore, the For Each activity (C) is the correct answer for implementing the Classification Loop according to UiPath best practices and the given diagram.
