UiPath-ADPv1 Practice Test 17 — 15 Questions

Question 1

A developer is automating a Citrix-published application. Standard UI Automation activities cannot see any elements inside the Citrix session, so the team decides to use UiPath Computer Vision (CV) activities. Which two statements about Computer Vision in this scenario are correct? (Choose two.)

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

Accepted Answer

CV activities can interact with elements inside a Citrix session because they analyze pixels from screenshots rather than relying on the operating system's accessibility tree.. Computer Vision is designed for environments like Citrix where the accessibility tree is unavailable. It requires the UiPath Computer Vision server and an API key, and it works by analyzing screenshots, which allows it to see elements inside a virtualized session. It does not generate Object Repository selectors, does not work with hidden windows, and is not inherently faster than UI Automation.

Answer

CV activities automatically generate stable selectors that are stored in the Object Repository and can be reused without re-indication.

Answer

CV activities eliminate the need for the Citrix session to be visible on the screen, because they can capture hidden windows.

Answer

CV activities are always faster than standard UI Automation activities because they process screenshots in parallel.

Question 2

An attended automation running on a user's workstation needs to interact with a Java-based application. The robot must click a button that appears only after a progress bar completes. The progress bar duration varies. Which UiPath feature should you use to reliably wait for the button to become available before clicking?

Accepted Answer

Wait Element Appear activity. Wait Element Appear is the correct feature because it actively monitors the UI for the button's appearance and proceeds as soon as it is available. It handles variable wait times by polling within a specified timeout, making it ideal for dynamic applications. This reduces failures and improves efficiency compared to fixed delays or manual retry loops.

Answer

Element Exists activity in a Retry Scope

Answer

Delay activity with a fixed duration

Answer

Wait Element Vanish activity

Question 3

You are automating a desktop application that opens multiple child windows with identical titles. You must interact with the third window in the order it was opened. Which UiPath approach is most reliable for selecting that specific window instance?

Accepted Answer

Use the 'Window' activities with a selector that includes a stable attribute unique to the third window, such as a distinct title suffix or a child element that only that instance contains.. When multiple windows share a title, title-only selectors are ambiguous and may attach to the wrong instance. The reliable method is to include an attribute unique to the target window, such as a title suffix or a child element present only in that instance. This makes the selector unambiguous and keeps subsequent UI activities pointed at the intended window.

Answer

Use the 'Use Application/Browser' activity with the window title as the selector and enable 'Open in new window'.

Answer

Use the 'Get Process' activity to retrieve the process, then index into its MainWindowHandle collection to pick the third window.

Answer

Use the 'Find Window' activity with a selector that includes the window's process id and its instance index, then pass the result to subsequent UI activities.

Question 4

A developer is using a 'For Each' activity to iterate over a DataTable and needs to access the value of a column named 'Amount' for each row. The column may contain DBNull.Value for some rows. Which expression safely retrieves the amount as a Decimal, handling DBNull by returning 0?

Accepted Answer

If(row.IsNull("Amount"), 0D, CDec(row("Amount"))). The correct expression uses row.IsNull to check for DBNull and the If operator to return 0D when null, otherwise convert to Decimal. This safely handles null values and avoids exceptions. Other options either throw exceptions on DBNull or incorrectly parse the value.

Answer

Decimal.Parse(row("Amount").ToString())

Answer

CDec(row("Amount"))

Answer

row.Field(Of Decimal)("Amount")

Question 5

A developer needs to call a REST API that requires an API key to be passed as a query parameter named 'api_key'. The developer is using the UiPath HTTP Request activity. Which property should the developer use to add this parameter?

Accepted Answer

Add the parameter to the URL property by appending "?api_key=value" to the endpoint URL.. Query parameters are appended to the URL. Since the HTTP Request activity does not have a dedicated query parameter field, the developer must include "?api_key=value" in the URL property. This is the standard method for passing API keys as query parameters, ensuring the API can authenticate the request.

Answer

Add a JSON body with {"api_key": "value"} in the Body property.

Answer

Use the Authentication property to select "API Key" and enter the value.

Answer

Add a header with Name "api_key" and Value "value" in the Headers property.

Question 6

While debugging an automation, you notice that a variable updates correctly, but the UI element based on that variable does not change. What is the most likely cause?

Accepted Answer

The input method did not trigger the 'on-change' event required by the application.. If the variable is correct but the UI hasn't updated, the application is likely experiencing a delay in rendering. Modern web applications often require a trigger to refresh the UI after a value is input. The most effective fix is to add a 'Simulate Click' or 'Send Hotkey' (like Enter or Tab) to force the browser to trigger its internal 'on-change' event, ensuring the UI reflects the new variable value.

Answer

The variable scope is too large.

Answer

The browser is stuck in a loop.

Answer

The selector is not unique enough.

Question 7

Which THREE actions can Autopilot for Developers perform to assist in troubleshooting existing workflows?

Accepted Answer

Analyzing error logs to suggest root cause fixes.. Autopilot can analyze error logs, suggest structural refactoring to improve stability, and explain complex code segments to developers. These actions are vital for modernizing technical debt and reducing MTTR (Mean Time To Repair). By providing contextual advice, Autopilot empowers developers to resolve issues faster while simultaneously learning best practices for more robust automation design in the long term.

Answer

Automatically refactoring all workflows to 100% test coverage.

Answer

Creating automatic pull requests for all repository changes.

Question 8

Which TWO of the following are best practices for maintaining clean and scalable variables within a UiPath project?

Accepted Answer

Limit the scope of variables to the smallest container necessary to reduce memory usage.. Effective variable management minimizes memory overhead and prevents naming collisions in large projects. Using descriptive naming conventions allows developers to understand data purpose at a glance, while limiting the scope of variables to the smallest necessary sequence or flow reduces the risk of accidental modification. These practices are fundamental to creating maintainable automations that are easy for other developers to debug and modify.

Answer

Use PascalCase for all variable names to ensure consistency across the automation.

Answer

Declare all variables as Global at the top level to avoid scope-related errors.

Answer

Initialize all variables with a default value to prevent NullReferenceExceptions.

Question 9

While debugging a background process, the robot intermittently fails to click a button. You suspect the UI element is not ready, despite using the 'Click' activity. What is the most robust way to ensure the element is interactive?

Accepted Answer

Use the 'Wait Element Appear' activity before the click to synchronize.. Using the 'Wait Element Vanish' or 'Wait Element Appear' activities is the industry-standard way to synchronize the robot with the application state. By explicitly waiting for the target element to become available or for a loading spinner to disappear before clicking, you eliminate timing issues. This is significantly more reliable than hard-coded delays, as it reacts to the actual state of the UI instead of arbitrary time intervals.

Answer

Add a hard-coded 'Delay' of 10 seconds before every click.

Answer

Disable the 'WaitForReady' property to ensure immediate execution.

Answer

Replace the 'Click' activity with a 'Send Hotkey' activity.

Question 10

A developer is using UiPath Autopilot for Developers to generate a workflow that interacts with a queue in Orchestrator. The developer wants to ensure the generated workflow handles transactions correctly. Which two actions should the developer take to improve the reliability of the generated workflow? (Choose two.)

Accepted Answer

Ask Autopilot to generate a Try Catch block around the transaction processing and specify which exceptions should mark the item as failed.. Reliable queue-based workflows require precise context and explicit error handling. Specifying the queue name, item type, and status transitions ensures the generated activities match the Orchestrator configuration. Prompting Autopilot to generate a Try Catch with defined failure conditions ensures exceptions are handled correctly. Together, these actions produce a more robust generated workflow.

Answer

Instruct Autopilot to replace all queue activities with direct API calls to the Orchestrator REST endpoints.

Answer

Ask Autopilot to generate the workflow without specifying the Orchestrator folder path, since Autopilot will infer it from the project settings.

Answer

Request that Autopilot disable the Orchestrator queue retry mechanism to avoid duplicate processing.

Question 11

An automation developer is using the HTTP Request activity in UiPath Studio to call a REST API that requires a bearer token. The token is stored in Orchestrator as an asset named "APIToken". The developer needs to include the token in the request header. Which approach should be used?

Accepted Answer

Add a header named "Authorization" with the value "Bearer " + token, where token is retrieved using the Get Asset activity.. The correct approach is to retrieve the token from Orchestrator using the Get Asset activity and then add it to the request headers as "Authorization: Bearer <token>". This is the standard method for bearer token authentication in REST APIs and is fully supported by the HTTP Request activity through its Headers property.

Answer

Append the token as a query parameter, such as "?token=<token>", to the request URL.

Answer

Use the OAuth2 activity with the token as the AccessToken property and configure the HTTP Request to use that connection.

Answer

Set the AuthenticationType property of the HTTP Request activity to "Bearer" and provide the token in the Password field.

Question 12

You are debugging a Workflow that uses a 'State Machine' and notice it gets stuck in a loop between two states. Which tool provides the best visibility into the transition conditions during runtime?

Accepted Answer

Place a breakpoint on the 'Transition' condition and inspect variables in the Locals panel.. The 'Breakpoints' and 'Locals' panels are essential for monitoring State Machines. By placing a breakpoint on the 'Condition' expression of a transition, the developer can pause the robot just before it evaluates the logic. Inspecting the variables involved in the condition ensures that the evaluation is behaving as expected, allowing you to diagnose why the robot is incorrectly re-entering a specific state repeatedly.

Answer

Use the 'Validate' button in the design ribbon.

Answer

Check the 'Output' panel for infinite loop warnings.

Answer

Increase the 'MaxLoop' property of the State Machine.

Question 13

A developer is building a UiPath automation that consumes a REST API. The API returns a JSON response with a 'status' field and a 'data' array. The developer needs to handle both successful responses and error responses gracefully. Which two actions should the developer take to ensure robust error handling? (Choose two.)

Accepted Answer

Use a Try Catch activity around the HTTP Request and handle specific exceptions like HTTPRequestException.. Robust error handling for API calls involves checking the HTTP status code to detect success or failure and using Try Catch to handle exceptions that may occur during the request. These two actions together ensure that both expected error responses and unexpected exceptions are managed, allowing the workflow to respond appropriately.

Answer

Deserialize the JSON response and check if the 'status' field equals 'success' before processing the 'data' array.

Answer

Configure the HTTP Request activity to ignore SSL certificate errors to avoid connection failures.

Answer

Set the HTTP Request activity's 'Continue On Error' property to True to prevent the workflow from stopping on any error.

Question 14

Which TWO of the following statements accurately describe the requirements or behaviors for using Autopilot for Developers?

Accepted Answer

Generated code suggestions must always be reviewed by a developer.. Autopilot for Developers requires an active connection to the UiPath cloud platform to leverage the underlying LLM processing capabilities. Furthermore, the generated code must undergo human verification, as the AI acts as an assistant rather than an autonomous replacement for developer logic. Understanding these boundaries ensures that developers maintain high quality, secure, and compliant automation code in their projects.

Answer

Autopilot functions entirely offline without a network connection.

Answer

Autopilot is limited to only C# based workflow projects.

Answer

Autopilot automatically deploys code to production once created.

Question 15

When automating a process that requires the user to pick files from their local machine, which TWO activities or methods are most appropriate for an attended robot?

Accepted Answer

Select File activity. Using standard Windows dialogs ensures the user has a familiar experience, reducing confusion. The 'Select File' activity provides a native interface for selecting single files, while custom 'Input Dialogs' can be adapted for more complex scenarios. These methods keep the interaction secure and intuitive, allowing users to browse their own file system safely without giving the robot unnecessary broad access to their entire directory structure.

Answer

Hardcoding file paths in a variable

Answer

Reading all system files into an array

Answer

Using a Type Into activity to paste the full file path
