UiPath-ADAv1 Practice Test 15 — 15 Questions

Question 1

You are working on a UiPath automation project where you have a variable named 'TransactionAmount' of type Double defined in the Main workflow. You need to pass this value to an invoked workflow called 'ProcessTransaction.xaml' which expects a Double argument named 'Amount'. How should you configure the Invoke Workflow activity?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

In the Invoke Workflow activity, set the 'Amount' argument to the value of 'TransactionAmount' by using the expression 'TransactionAmount'.. To pass a variable's value to an invoked workflow's argument, you map the argument to the variable in the Invoke Workflow activity. The data types must match. Using 'TransactionAmount' directly is correct because it is already a Double. Converting to String or using redundant conversion is unnecessary and can cause errors or confusion.

Answer

In the Invoke Workflow activity, set the 'Amount' argument to the value of 'TransactionAmount' by using the expression 'CDbl(TransactionAmount)'.

Answer

In the Invoke Workflow activity, set the 'Amount' argument to the value of 'TransactionAmount' by using the expression 'TransactionAmount.ToString'.

Answer

In the Invoke Workflow activity, set the 'Amount' argument to the value of 'TransactionAmount' by using the expression 'CStr(TransactionAmount)'.

Question 2

A developer is debugging a workflow that intermittently throws a 'UiPath.Core.ElementNotFoundException' when clicking a button. The developer wants to inspect the state of the application and the variable values at the exact moment the exception occurs, without modifying the workflow logic permanently. Which approach best allows this?

Accepted Answer

Add a Breakpoint on the Click activity, run the workflow in Debug mode, and when execution pauses, use the Locals panel to inspect variables and the UI Explorer to examine the application state.. Debugging intermittent UI exceptions requires pausing execution at the point of failure to inspect live data. A Breakpoint on the Click activity, combined with Debug mode, pauses the workflow before the activity executes, enabling the developer to examine variables in the Locals panel and use UI Explorer to verify the application state. This method is non-invasive and provides the most detailed diagnostic information without altering workflow logic.

Answer

Wrap the Click activity in a Try Catch block, and in the Catch block use a Take Screenshot activity to capture the screen, then rethrow the exception.

Answer

Add a Log Message activity immediately after the Click activity that writes the exception message to the Output panel, then run the workflow normally.

Answer

Set the Click activity's ContinueOnError property to True, run the workflow, and review the Output panel for the error message after execution completes.

Question 3

A developer is debugging a UiPath workflow and wants to log the exact error message and stack trace of an exception caught in a Catch block. Which expression should be used to retrieve this information from the exception object?

Accepted Answer

exception.ToString(). The 'ToString()' method of an exception object combines the exception type, message, and stack trace into a single string. This is the most complete way to capture error details for logging, as it includes both the exact error message and the stack trace, which are essential for debugging.

Answer

exception.Message

Answer

exception.StackTrace

Answer

exception.InnerException.Message

Question 4

A developer is building an RPA test that verifies an invoice total. The invoice total is calculated by a separate workflow that queries a database. To keep the test fast and deterministic, the developer wants to replace the database call with a static value during test execution. Which UiPath testing capability should be used?

Accepted Answer

Mocking. Mocking is the UiPath testing feature designed to replace the behavior of a specific activity with a controlled output, which removes external dependencies like databases. This makes the test fast, stable, and focused on the logic under test. The other options either do not isolate the dependency or are unrelated to simulating activity results.

Answer

Data-driven testing with an Excel file

Answer

Orchestrator queue with a test transaction

Answer

Workflow Analyzer rule enforcement

Question 5

A developer is building a library that will be used by multiple automation projects. The library contains several workflows that share common variables and arguments. To ensure that the library can be easily updated without breaking dependent projects, which versioning practice should the developer follow when publishing new versions of the library?

Accepted Answer

Increment the major version when making backward-incompatible changes, the minor version when adding backward-compatible functionality, and the patch version for backward-compatible bug fixes.. Semantic versioning uses major, minor, and patch increments to signal the type of change. Major versions indicate breaking changes, minor versions indicate backward-compatible additions, and patch versions indicate backward-compatible fixes. This convention lets consumers set version ranges and update safely, reducing the risk of breaking dependent automations.

Answer

Keep the version number constant and use the package description to indicate the changes made in each release.

Answer

Increment only the patch version for all changes, since libraries are internal and breaking changes are unlikely to affect other teams.

Answer

Always increment the major version for every change to ensure that consumers are forced to review and update their dependencies.

Question 6

You are building a UiPath automation in Studio and need a variable that holds a collection of invoice amounts so you can sum them later with a For Each activity. You want to declare it in the Variables panel with a type that supports indexed access and a Count property. Which data type should you select from the Browse for types dialog?

Accepted Answer

System.Collections.Generic.List(Of Double). A generic List(Of Double) provides strongly typed storage, dynamic resizing through Add, indexed access, and a Count property, all of which align with collecting invoice amounts before summation. Arrays are fixed-size, DataTable is tabular, and ArrayList is untyped, so none matches the requirement as cleanly as the generic list declared through Browse for types.

Answer

System.Data.DataTable

Answer

System.Collections.ArrayList

Answer

System.Double[]

Question 7

You are editing a workflow and need to quickly create a variable that will hold the output of a 'Read Range' activity. You want the variable to be created with the correct type automatically. Which action in UiPath Studio accomplishes this?

Accepted Answer

Press Ctrl+K in the DataTable property field of the Read Range activity.. Pressing Ctrl+K in a property field is the built-in shortcut to create a variable with the type automatically inferred from that property. For a Read Range output, this yields a DataTable variable. The other options either require manual steps, perform unrelated actions, or misrepresent Studio features.

Answer

Open the Variables panel and click 'Create Variable', then manually set the type to DataTable.

Answer

Use the 'Manage Packages' window to install a variable generation package.

Answer

Right-click the Read Range activity and select 'Extract as Workflow'.

Question 8

A company is expanding its automation program and needs to manage the full lifecycle of automation projects, from discovery and requirements gathering through development, testing, and deployment. They also want to enable collaboration between business users and developers, and track the performance of automations in production. Which two UiPath components should they implement to meet these requirements? (Choose two.)

Accepted Answer

UiPath Orchestrator. UiPath Automation Hub and UiPath Orchestrator together cover the full automation lifecycle. Automation Hub handles the discovery and requirements phases, enabling collaboration between business and IT, while Orchestrator manages deployment, execution, and monitoring of automations in production. Other components like Studio, Assistant, and Task Capture serve narrower roles and do not fulfill the end-to-end management and tracking needs.

Answer

UiPath Assistant

Answer

UiPath Studio

Answer

UiPath Task Capture

Question 9

An automation developer has configured an Integration Service connection to a Google Drive account using OAuth 2.0. The connection was working, but suddenly all activities using it fail with an authentication error. Upon checking, the developer finds that the refresh token has been revoked. What is the most likely cause?

Accepted Answer

The user who authorized the connection revoked access from their Google account settings.. The failure is due to a revoked refresh token, which commonly happens when the user who granted access removes the application from their account permissions. This invalidates the token and prevents the connection from refreshing access. Other options like client secret expiration or license issues would not cause a specific refresh token revocation, and they would typically affect multiple connections or produce different errors.

Answer

The OAuth 2.0 client secret expired after 90 days.

Answer

The UiPath Robot service account password was changed, invalidating the connection.

Answer

The Integration Service license expired, disabling all connections.

Question 10

A developer is debugging a workflow that intermittently fails when interacting with a legacy application. The developer wants to capture the state of all variables and the call stack at the moment the exception occurs, without stopping the debugging session. Which feature in UiPath Studio should the developer use?

Accepted Answer

Enable the 'Break on Exception' option in the Debug ribbon and use the Locals and Call Stack panels when execution pauses.. Enabling 'Break on Exception' in the Debug ribbon instructs UiPath Studio to pause execution immediately when any exception is thrown. At that point, the developer can examine the Locals panel for variable values and the Call Stack panel to see the sequence of workflow calls. This is the most efficient way to capture the state for intermittent failures without stopping the debugging session.

Answer

Use the 'Step Into' debugging command to execute the workflow line by line until the exception occurs.

Answer

Add a Try-Catch activity around the entire workflow, log the exception message, and continue execution.

Answer

Set a breakpoint on the activity that throws the exception and use the Locals panel to inspect variables.

Question 11

A developer is configuring a Global Exception Handler in UiPath Studio. The handler uses a Try Catch activity and needs to decide whether to retry the failed transaction or terminate the process. Which TWO of the following statements about the Global Exception Handler are correct? (Choose two.)

Accepted Answer

The Global Exception Handler can be used to catch exceptions that are not handled by any local Try Catch activity.. The Global Exception Handler catches unhandled exceptions that propagate from the main workflow, and it provides access to the exception object for inspection. It does not automatically retry the workflow, nor does it catch Orchestrator-level errors or restrict usage to unattended scenarios.

Answer

The Global Exception Handler can only be used in unattended automation scenarios.

Answer

The Global Exception Handler can be configured to retry the entire workflow from the beginning automatically.

Answer

The Global Exception Handler can be used to catch exceptions thrown by the Orchestrator when starting a job.

Question 12

A developer needs to create a test case that checks whether a newly added 'Calculate Discount' workflow returns the correct discount amount for a given customer type. The developer wants to ensure the test can be run independently and repeatedly. Which project template should the developer use?

Accepted Answer

Test Automation Project. The Test Automation Project template is purpose-built for creating test cases in UiPath. It includes the necessary testing activities and project structure to support independent and repeatable test execution. Other templates are designed for production automation or reusable components, not for test case development.

Answer

Library

Answer

REFramework

Answer

Process

Question 13

A developer needs to log a custom message that includes the current invoice number and a status update. The message should appear in Orchestrator logs with a severity that indicates normal operation but is more significant than verbose details. Which activity and log level should they use?

Accepted Answer

Log Message with level 'Info'. The Log Message activity is the correct tool for writing custom log entries to Orchestrator. Among the available levels, Information is designed for normal operational messages that confirm progress or state. It is more significant than Verbose but less severe than Warning. Using Information ensures the message is captured under typical production log settings while avoiding unnecessary noise or false alarms.

Answer

Log Message with level 'Warning'

Answer

Log Message with level 'Verbose'

Answer

Write Line with level 'Info'

Question 14

A developer is preparing to publish a custom library to Orchestrator so that other teams can use it in their automation projects. Which two actions should the developer take to ensure the library is properly published and consumable? (Choose two.)

Accepted Answer

Publish the library to the Orchestrator tenant feed or a custom NuGet feed that the target projects can access.. To publish a library for others to use, the developer must configure the project's metadata and publish it to a feed that consumers can access, such as the Orchestrator tenant feed. These steps ensure the package is identifiable and resolvable. Other actions like queue definitions or manual file copying do not distribute libraries properly.

Answer

Set the library's target framework to the same version used by all consuming projects to avoid compatibility issues.

Answer

Add the library as a dependency to the Orchestrator queue definition so that Robots can download it automatically.

Answer

Copy the library's .nupkg file into each consuming project's folder and reference it manually.

Question 15

A developer wants to log a warning message that will appear in the Orchestrator logs when a business rule is violated, such as an invoice amount exceeding a threshold. The message should be easily identifiable as a warning. Which activity should the developer use?

Accepted Answer

Log Message with Level set to Warn. The Log Message activity with Level set to Warn writes a log entry with Warning severity, which appears in Orchestrator logs and can be filtered by level. This makes it the appropriate choice for logging a business rule violation that should be easily identifiable as a warning. Other activities either do not write to Orchestrator logs or do not set the severity to Warning.

Answer

Write Line with a warning prefix

Answer

Log Entry with Level set to Info

Answer

Add Log Fields with a 'Warning' field
