RPA Robotic Process Automation 3

Question 1

What is 'screen scraping' in RPA, and when is it typically used?

Accepted Answer

Extracting data from UI elements when no API or structured data export exists

Answer

Screen scraping captures data displayed in application interfaces, and is used when legacy systems lack APIs or database access.

Question 2

Which cognitive/AI capability extends basic RPA to handle unstructured data like scanned invoices?

Accepted Answer

Optical Character Recognition (OCR)

Answer

OCR converts images or scanned documents into machine-readable text, enabling RPA bots to process unstructured inputs.

Question 3

A bot repeatedly fails when a pop-up dialog appears unexpectedly. What is the BEST long-term fix?

Accepted Answer

Add exception handling to detect and dismiss unexpected pop-ups

Answer

Robust exception handling that explicitly monitors for unexpected UI elements is the proper engineering solution for dynamic application behavior.

Question 4

In UiPath, what is the purpose of the 'Invoke Workflow' activity?

Accepted Answer

Calling a reusable sub-workflow from within a main workflow

Answer

'Invoke Workflow' promotes modularity by allowing one workflow file to call another, enabling code reuse and easier maintenance.

Question 5

What does 'straight-through processing' (STP) mean in an RPA context?

Accepted Answer

A transaction is completed end-to-end by the bot without any human intervention

Answer

STP rate measures the percentage of transactions that bots handle fully automatically from start to finish with zero human touch.
