UiPath-ADPv1 Practice Test 16 — 15 Questions

Question 1

A workflow receives a full customer name as a single string variable, for example 'Ada Lovelace', and must populate separate FirstName and LastName variables. The names always contain exactly one space separating the two parts, and surrounding whitespace may be present. Which expression correctly extracts the two parts?

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

Accepted Answer

fullName.Split(" "c)(0) for the first name and fullName.Split(" "c)(1) for the last name, after trimming the input first.. Given a single separating space and possible surrounding whitespace, trimming first and then splitting on the space character yields an array with the first name at index zero and the last name at index one. Indexing those elements populates the two variables correctly. Substring variants mishandle the delimiter or assume equal lengths, and assigning the raw array is a type error.

Answer

fullName.Trim().Replace(" ", "") split into equal halves using the string length divided by two.

Answer

fullName.Trim().Split(" "c) assigned directly to the FirstName and LastName variables as an array.

Answer

fullName.Substring(0, fullName.IndexOf(" ")) for the first name and fullName.Substring(fullName.IndexOf(" ")) for the last name.

Question 2

A developer is automating a process that calls a REST API which returns a large JSON response containing a 'results' array with 10,000 objects. The developer uses the Deserialize JSON activity and then a For Each loop to process each object. The workflow is running slowly and consuming high memory. Which approach should the developer take to improve performance while still processing all objects?

Accepted Answer

Use the HTTP Request activity with the 'Save Response to File' option, then parse the JSON file in chunks using a streaming JSON parser like Newtonsoft.Json.JsonTextReader.. For large JSON responses, loading the entire payload into memory with Deserialize JSON can cause performance issues. Saving the response to a file and using a streaming parser such as JsonTextReader allows incremental processing, reducing memory footprint. This approach is more efficient for large datasets and still processes all objects. Other options either do not exist in UiPath or do not solve the memory problem.

Answer

Set the 'TypeArgument' property of the Deserialize JSON activity to 'System.Collections.Generic.IEnumerable(Of JObject)' to enable lazy loading.

Answer

Use the 'Deserialize JSON Array' activity instead of 'Deserialize JSON' to stream the array elements one by one.

Answer

Use the 'JSON to DataTable' activity to convert the JSON to a DataTable, then use a For Each Row activity to process the data.

Question 3

You are debugging a UiPath automation that intermittently fails when interacting with a web application. The error message indicates a 'UI element not found' exception, but the element exists when you manually check. You suspect the issue is related to timing or dynamic content. Which two actions should you take to diagnose and resolve the issue? (Choose two.)

Accepted Answer

Use the 'Element Exists' activity with a timeout to check if the element appears. Intermittent 'UI element not found' errors often stem from timing issues or fragile selectors. Using 'Element Exists' with a timeout helps determine if the element is simply slow to load. Validating and refining the selector with UiExplorer ensures it is robust against dynamic changes. Together, these actions diagnose both timing and selector reliability.

Answer

Add a 'Wait Element Vanish' activity before the failing activity

Answer

Increase the 'Delay before' property on the failing activity to 5000 milliseconds

Answer

Enable 'Simulate Click' or 'Send Window Messages' for the click activity

Question 4

A developer is building a UiPath automation using the Robotic Enterprise Framework template. During the Get Transaction Data state, the workflow retrieves queue items from an Orchestrator queue. The developer notices that when the queue is empty, the automation still transitions to the Process state and then immediately ends. What is the most likely cause of this behavior?

Accepted Answer

The 'TransactionItem' variable is not being set to Nothing when the queue is empty.. The REFramework relies on setting TransactionItem to Nothing to detect the end of the queue. When no items remain, Get Transaction Data should assign Nothing to TransactionItem, causing the next loop iteration to skip Process and move to End Process. If this assignment is missing, the framework may incorrectly enter Process with an invalid item, then quickly terminate.

Answer

The 'QueueName' argument in the Config.xlsx file is misspelled, causing the queue to return no items.

Answer

The 'TransactionNumber' variable is not incremented in the Process state.

Answer

The 'ShouldStop' variable is not being checked in the Get Transaction Data state.

Question 5

You are automating a WPF application whose window title changes with the logged-in user, and whose main content is hosted inside a dynamically created tab control. Using the default selector generated by UiPath Studio, the automation intermittently fails to find the tab. Which selector strategy should you apply to make the selector resilient?

Accepted Answer

Use the UiPath Selector Editor to add an anchor based on the tab's static AutomationId, and replace volatile attributes with wildcards.. The Selector Editor is the right tool because it exposes the element tree and lets you replace volatile attributes with wildcards while adding a stable anchor such as AutomationId. For WPF tab controls, AutomationId is typically static even when the window title and tab container change, so anchoring on it makes the selector deterministic. Fuzzy selectors and timeout changes only mask the problem, and a single wildcarded title is too loose to reliably locate the tab.

Answer

Enable the UiPath UI Automation 'Fuzzy selector' option on the activity and leave the original selector unchanged.

Answer

Switch every activity in the workflow to use the Classic experience and set the Target.WaitForReady property to None.

Answer

Replace the full selector with a single wildcarded window title attribute and rely on the default timeout to locate the tab.

Question 6

You are debugging a UiPath workflow and want to inspect the current value of a variable that is not displayed in the Locals panel because it is out of scope. Which feature should you use to evaluate the variable's value at the current breakpoint?

Accepted Answer

The 'Immediate' panel. The Immediate panel is designed for evaluating expressions and variables on the fly during a debugging session. When a variable is not visible in the Locals panel, you can type its name into the Immediate panel to retrieve its current value, as long as it is in scope at the breakpoint. This provides a quick and efficient way to inspect variables without altering the workflow or adding them to the Watch panel.

Answer

The 'Breakpoints' panel

Answer

The 'Watch' panel

Answer

The 'Call Stack' panel

Question 7

While debugging a long-running UiPath automation, you want to execute a single activity that assigns a test value to a variable, verify its effect immediately, and continue without restarting the whole process. The activity has not yet been reached by the current execution pointer. Which debugging capability should you use?

Accepted Answer

Use the Immediate panel to type and execute a statement that assigns the test value to the variable.. The Immediate panel runs expressions and assignments against the live debugging context, so you can set a variable to a test value and observe the result in Locals right away. Because it does not change the execution pointer or restart the process, you keep your current state and can continue debugging from where you paused, which is exactly the interactive verification needed.

Answer

Modify the variable's default value in the Variables panel and restart the process in Debug mode.

Answer

Use Step Over repeatedly until the pointer reaches the assignment activity.

Answer

Set a breakpoint on the assignment activity and press Continue to jump directly to it.

Question 8

You are debugging a UiPath workflow and need to understand the sequence of nested workflow invocations that led to the current paused activity, including which workflow called which. Which debugging panel displays this hierarchical execution path?

Accepted Answer

The Call Stack panel.. The Call Stack panel presents the active execution frames in order, from the top-level process through each nested workflow invocation down to the current activity. This hierarchical view is precisely what reveals the chain of workflow calls that led to the paused point, and selecting a frame lets you inspect that frame's variables and arguments.

Answer

The Breakpoints panel.

Answer

The Locals panel.

Answer

The Output panel.

Question 9

You are debugging a UiPath workflow that processes items in a loop. You want to observe how a counter variable increments after each iteration, but you do not want to pause execution at every step. Which debugging feature allows you to monitor the variable's value without stopping the workflow?

Accepted Answer

Add the variable to the 'Watch' panel and run the workflow in Debug mode.. The Watch panel is designed for monitoring variables and expressions during debugging without interrupting execution. By adding the counter variable to the Watch panel and running in Debug mode, you can see its value update in real time as the loop iterates. This provides continuous visibility without the need for breakpoints or workflow modifications, making it the most efficient method for this scenario.

Answer

Set a breakpoint on the increment activity and use the 'Step Over' action.

Answer

Add a 'Log Message' activity inside the loop to output the counter value.

Answer

Use the 'Locals' panel and enable 'Execution Trail'.

Question 10

You are building an automation that must interact with a Citrix-published application where no UI Automation provider is available. You decide to use UiPath Computer Vision activities. Which two configurations are required for the CV activities to work correctly? (Choose two.)

Accepted Answer

Ensure the CV screen scope has a valid Computer Vision server endpoint and API key configured in Orchestrator or Studio.. CV activities require a CV Screen Scope to define the analyzed region and a valid Computer Vision server endpoint with an API key. The scope gives CV the visual context of the Citrix window or desktop, and the endpoint enables the CV service to detect elements from pixels. The Remote Runtime and Citrix extension are an alternative UI Automation approach, and WaitForReady tuning is unrelated to CV detection, so those options are not required.

Answer

Install and configure the UiPath.UIAutomation.Activities package only, because CV is included in the standard UI Automation package.

Answer

Enable the UiPath Remote Runtime on the Citrix server and register the Citrix extension in Studio.

Answer

Set the Target.WaitForReady property to None on every CV activity to improve detection speed.

Question 11

You are automating a web application that renders a data grid inside an iframe. Standard UiPath UI Automation activities can see the iframe but not the grid inside it, and the grid's rows are generated by JavaScript after the iframe loads. Which UiPath approach should you use to interact with the grid rows reliably?

Accepted Answer

Use the UiPath 'Use Application/Browser' activity on the parent page, then add a 'Window Scope' or nested 'Use Application/Browser' with the iframe selector to reach the grid.. The correct approach is to nest a scope that targets the iframe element inside the parent browser scope, which switches the automation context into the iframe's document. Once inside, the JavaScript-generated grid rows are visible to standard UI Automation activities. Attach Browser, Use Application/Browser on the iframe URL, and Navigate To all operate on top-level windows or URLs, so they cannot cross the iframe boundary and leave the grid unreachable.

Answer

Use the UiPath 'Navigate To' activity with the iframe URL, then use the 'Extract Structured Data' activity on the grid.

Answer

Use the UiPath Browser automation activities with the Attach Browser activity targeting the iframe's URL, then use Click and Get Text on the grid rows.

Answer

Use the UiPath 'Use Application/Browser' activity with the iframe URL, then use the 'Indicate on screen' feature to select the grid rows directly.

Question 12

A developer is automating a web application that uses a complex JavaScript framework. Standard UI Automation activities sometimes fail to detect elements, and the developer is considering using UiPath Computer Vision activities. Which two factors should the developer evaluate before deciding to use Computer Vision? (Choose two.)

Accepted Answer

The screen resolution and scaling must be consistent across all machines where the automation runs.. Before adopting Computer Vision, the developer must evaluate screen resolution and scaling consistency, because CV depends on visual recognition, and must ensure the CV service has an API key and internet connectivity, as it is cloud-based. These two factors directly affect whether CV can function reliably and are prerequisites for its use.

Answer

The application's UI elements must be exposed through the Microsoft UI Automation framework for CV to detect them.

Answer

The application must be running on a remote desktop or Citrix environment for CV to work.

Answer

The developer must disable all other UI Automation activities and use only CV activities in the workflow.

Question 13

You are automating a process that interacts with a SAP GUI transaction. The standard UiPath UI Automation activities can see the SAP window and its menu bar, but cannot detect the individual fields inside the transaction area. Which configuration should you apply to enable reliable element detection inside the SAP transaction?

Accepted Answer

Enable the 'SAP GUI Scripting' setting on both the SAP server and the SAP GUI client, and ensure the UiPath.UIAutomation.Activities package is configured to use the SAP framework.. SAP GUI transaction fields are only exposed to automation when SAP GUI Scripting is enabled on both the server and the client. UiPath's UI Automation activities can then use the SAP framework to detect and interact with individual controls inside the transaction area. Framework changes like AA or Java do not apply because SAP GUI does not expose those accessibility providers for its internal fields.

Answer

Change the project's UI Automation framework to 'AA' and re-indicate the SAP transaction fields, because Active Accessibility exposes all SAP controls.

Answer

Use the 'UiPath.SAP.Activities' package and replace all UI Automation activities with its dedicated SAP activities, because they do not require any server-side configuration.

Answer

Set the UiPath.UIAutomation.Activities package to use the 'Java' framework and re-indicate the elements, because SAP GUI is built on Java.

Question 14

You are debugging a UiPath workflow and notice that a variable's value is not what you expect at a certain point. You want to view the variable's value without modifying the workflow or adding any logging activities. Which debugging panel should you use?

Accepted Answer

The 'Locals' panel.. The Locals panel automatically displays all variables in the current scope when execution is paused. It requires no configuration and provides immediate visibility into variable values. The Immediate panel requires manual commands, the Watch panel requires pre-selection of variables, and the Breakpoints panel does not show values. Therefore, the Locals panel is the correct choice for quickly inspecting a variable without modifying the workflow.

Answer

The 'Immediate' panel.

Answer

The 'Watch' panel.

Answer

The 'Breakpoints' panel.

Question 15

A developer is troubleshooting a REFramework automation that processes transactions from an Orchestrator queue. The automation occasionally throws a BusinessRuleException due to invalid data in a transaction. The developer observes that these transactions are marked as 'Failed' in Orchestrator instead of 'Business Exception'. What is the most likely reason for this misclassification?

Accepted Answer

The BusinessRuleException is being caught and rethrown as a System.Exception in the Process state.. BusinessRuleException must propagate as-is to be correctly classified. If it is caught and rethrown as a System.Exception, the REFramework's exception handler will treat it as a system exception, leading to a 'Failed' status. The correct approach is to either let the BusinessRuleException bubble up or rethrow it using a Rethrow activity to preserve its type.

Answer

The 'Max Retry Number' for the queue is set to 0, causing business exceptions to be treated as system exceptions.

Answer

The Orchestrator queue is not configured to recognize BusinessRuleException as a separate status.

Answer

The 'SetTransactionStatus' workflow has been modified to always set the status to 'Failed'.
