- Question 1Beginner
Data Manipulation · RegEx
True or False: When using the 'Matches' activity in UiPath Studio, the 'Result' property outputs a Boolean value indicating whether a match was found.
Show answer & explanation
Correct answer: B
This is false. The 'Matches' activity outputs an 'IEnumerable ' collection, which contains all the matches found in the input string. The 'Is Match' activity is the one that outputs a Boolean value.
- Question 2Intermediate
RPA Testing · Test Cases
A developer is creating a data-driven test case for a workflow that calculates loan eligibility. The test case uses an Excel file with columns for 'Income', 'CreditScore', and 'ExpectedResult'. The developer needs to validate that the workflow's output matches the 'ExpectedResult' for each row. Which activity should be used to perform this validation within the test case?
Show answer & explanation
Correct answer: B
The 'Verify Expression' activity is part of the RPA Testing activities pack and is the standard way to create assertions in a test case. It evaluates a boolean expression and marks the test case as passed or failed based on the result. This integrates directly with the Test Explorer and provides clear pass/fail outcomes, which is superior to using a simple 'If' condition for testing purposes.

Integration Service · Connectors and Triggers
A developer needs to connect a UiPath automation to an external CRM system's API that is not available in the standard connector list. The goal is to trigger the automation whenever a new 'High Priority' lead is created in the CRM. The CRM can be configured to send a webhook with a JSON payload for this event. Which UiPath product should be used to receive this webhook and trigger the corresponding process?
Show answer & explanation
Correct answer: D
UiPath Integration Service is designed to handle API-based integrations and event-driven triggers. It provides a dedicated feature to create custom webhook triggers that can listen for incoming HTTP requests from external systems. This allows the CRM to send a webhook to a unique URL provided by Integration Service, which then automatically starts a specified Orchestrator process, passing the JSON payload as input arguments.

Data Manipulation · DataTables
A developer has a DataTable named
dt_Saleswith columns 'Region', 'Product', and 'Amount'. The developer needs to create a new DataTable that contains only the rows where the 'Region' is 'North' and the 'Amount' is greater than 1000. What is the most efficient way to achieve this using standard UiPath activities or methods?Show answer & explanation
Correct answer: C
The
DataTable.Select()method provides a powerful and highly efficient way to filter rows based on a SQL-like query string. This single expression filters the rows in memory and then uses.CopyToDataTable()to create a new DataTable from the results. It is significantly more performant than iterating through each row with a 'For Each Row' loop or using the 'Filter Data Table' activity, especially for large datasets. - Question 5Beginner
Orchestrator · Assets
During a code review, a senior developer points out that a project is not following best practices because sensitive credentials (a username and password) are stored in a local configuration file. The process is intended to run unattended from Orchestrator. What is the most secure and appropriate method for managing these credentials?
Show answer & explanation
Correct answer: C
Orchestrator Assets are the standard, secure way to manage credentials and other configuration data. A Credential Asset encrypts the password at rest and provides centralized management and auditing. The 'Get Credential' activity retrieves the username and SecureString password at runtime without exposing them in the code, logs, or project files. This is the recommended best practice for handling sensitive information.
- Question 6Intermediate
Version Control Integration · Git Integration
A developer is using the Git integration in UiPath Studio. After pulling the latest changes from the remote repository, Studio indicates a merge conflict in the
project.jsonfile. What is the recommended first step to resolve this conflict within Studio?Show answer & explanation
Correct answer: B
UiPath Studio's Git integration provides a built-in tool for handling merge conflicts. When a conflict is detected, the correct procedure is to right-click the conflicted file and select 'Resolve Conflicts'. This opens a merge editor window that shows the conflicting versions side-by-side ('Mine' for local changes, 'Theirs' for remote changes), allowing the developer to choose which changes to keep before completing the merge.

PDF Automation · PDF Data Extraction
A logistics company needs to automate the processing of shipping manifests received as scanned PDF documents. The manifests have a consistent layout, but the text quality can vary. The automation must extract the tracking number, destination address, and list of items. Which combination of activities is best suited for this task?
flowchart TD A[Start: Scanned PDF Received] --> B{Digitize Document}; B --> C[Extract Key Fields]; C --> D[Process Extracted Data]; D --> E[End];Show answer & explanation
Correct answer: B
Since the documents are scanned, OCR is required to make the text machine-readable. 'Read PDF with OCR' is the correct activity for this. Because the layout is consistent, using 'Anchor Base' is a robust method to extract data. It can find a stable element (like the label 'Tracking Number:') and then use that as an anchor to find the adjacent data, even if its exact screen position varies slightly.
- Question 8Intermediate
Workflow Analyzer · Workflow Analysis
A developer is using the Workflow Analyzer to enforce coding standards. The requirement is to ensure that no 'Write Line' activities are used in the final project, as all logging must be done using 'Log Message'. How can the developer configure the Workflow Analyzer to enforce this rule and prevent the project from being published if it's violated?
Show answer & explanation
Correct answer: C
The 'Activity Usage' rule (ST-USG-014) is designed to restrict which activities can be used in a project. By adding 'WriteLine' to its 'ForbiddenActivities' parameter list and setting the 'Action' to 'Error', the Workflow Analyzer will report a validation error if a 'Write Line' activity is found. This error will prevent the project from being published, thus enforcing the standard.
- Question 9Advanced
Data Manipulation · Collections
A developer needs to iterate through a collection of email addresses stored in a
List. For each email, the process should check if it belongs to the 'example.com' domain and, if so, add it to a new list of corporate emails. Which code snippet, used in an 'Assign' activity, performs this filtering operation most concisely using LINQ?Show answer & explanation
Correct answer: A
This expression uses a LINQ (Language Integrated Query) method,
.Where(), to filter theallEmailslist. The lambda functionFunction(email) email.EndsWith("@example.com")provides the condition for the filter. Finally,.ToList()converts the filtered result back into a newList. This is the most efficient and readable way to perform such filtering in a single line of code. - Question 10Advanced
Orchestrator · Queues
Case Study: Insurance Claim Processing Automation
A mid-sized insurance company wants to automate the initial processing of vehicle damage claims. The current manual process involves an agent monitoring a dedicated email inbox. When a new claim email arrives, it contains a policy number in the subject line and a PDF form attached. The agent opens the PDF, extracts the claimant's name, date of the incident, and vehicle identification number (VIN). They then log into a web-based portal, search for the policy number, validate that the claimant's name matches the policyholder, and enter the incident date and VIN to create a new claim record. Finally, the agent moves the processed email to an 'Archive' subfolder.
Technical Requirements:
- The automation must run unattended and process emails as they arrive.
- It must handle both native and scanned PDF claim forms.
- All actions must be logged for auditing, including the creation of each new claim record.
- If the policy number is not found or the claimant's name does not match, the email should be flagged for manual review by adding a specific category and moving it to a 'Review' folder.
- The solution should be scalable to handle hundreds of claims per day and be resilient to temporary outages of the web portal.
Which architectural design provides the most robust and scalable solution to meet all the requirements?
Show answer & explanation
Correct answer: B
This design, known as the Dispatcher/Performer model using Orchestrator Queues, is the best practice for scalable and resilient transaction-based processing. The Dispatcher handles ingestion, decoupling it from processing. The Performer processes each claim as a separate transaction from the queue. This allows for parallel processing by multiple robots, automatic retries for failed transactions (e.g., if the web portal is down), and provides detailed, per-transaction logging and reporting in Orchestrator, meeting all the stated requirements.
