RPA Robotic Process Automation 3 — Questions and Answers
Question 1: What is 'screen scraping' in RPA, and when is it typically used?
- Extracting data from UI elements when no API or structured data export exists (Correct answer)
- Taking screenshots for audit logs
- Scraping competitor websites for pricing data
- Removing sensitive data from screen recordings
Correct answer: Extracting data from UI elements when no API or structured data export exists
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?
- Optical Character Recognition (OCR) (Correct answer)
- Robotic Desktop Automation (RDA)
- Business Process Management (BPM)
- Extract, Transform, Load (ETL)
Correct answer: Optical Character Recognition (OCR)
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?
- Add exception handling to detect and dismiss unexpected pop-ups (Correct answer)
- Schedule the bot to run at a time when pop-ups are less likely
- Increase the bot's execution speed
- Switch to a different RPA tool
Correct answer: Add exception handling to detect and dismiss unexpected pop-ups
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?
- Calling a reusable sub-workflow from within a main workflow (Correct answer)
- Triggering an external web API endpoint
- Starting a new robot session on a remote machine
- Importing a library of pre-built activities
Correct answer: Calling a reusable sub-workflow from within a main workflow
'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?
- A transaction is completed end-to-end by the bot without any human intervention (Correct answer)
- The bot processes data in a straight sequential line without loops
- Automation that connects directly to a database without a UI
- A processing mode where bots skip error handling for speed
Correct answer: A transaction is completed end-to-end by the bot without any human intervention
STP rate measures the percentage of transactions that bots handle fully automatically from start to finish with zero human touch.
Question 6: Which RPA deployment model hosts the Orchestrator on the vendor's cloud infrastructure?
- Cloud/SaaS deployment (Correct answer)
- On-premises deployment
- Hybrid deployment
- Edge deployment
Correct answer: Cloud/SaaS deployment
In a SaaS (cloud) deployment, the RPA vendor manages and hosts the Orchestrator, reducing the organization's infrastructure burden.
Question 7: What is the recommended approach for storing application credentials used by an unattended RPA bot?
- In the Orchestrator's encrypted credential store or a vault like CyberArk (Correct answer)
- Hardcoded in the workflow file for reliability
- In a plain-text config file on the robot machine
- In a spreadsheet accessible only to the automation team
Correct answer: In the Orchestrator's encrypted credential store or a vault like CyberArk
Encrypted credential management systems ensure secrets are never exposed in code or logs and can be rotated centrally.
