UiPath-ADPv1 Generic Automation Development Practice Test 3 — 15 Questions

Question 1

A developer is building a UiPath automation that uses a Try Catch activity. Inside the Try block, a business rule exception is thrown by a Throw activity when an invoice amount exceeds a configured limit. The developer wants the Catch block to handle this specific business rule exception differently from system exceptions. Which Catch block configuration should be used?

Accepted Answer

Add a Catch block with the exception type set to BusinessRuleException before any System.Exception Catch block.. The correct approach is to use a Catch block typed to BusinessRuleException, placed before any System.Exception Catch block. UiPath evaluates Catch blocks sequentially, so the specific exception type must come first to be caught appropriately. This allows distinct handling for business rule violations versus system errors, which is essential for robust automation design. Other options either use overly broad exception types or invalid properties.

Answer

Add a Catch block with the exception type set to System.Exception and check the exception message for the business rule text.

Answer

Add a Catch block with the exception type set to System.Exception and set the 'Rethrow' property to True.

Answer

Add a Catch block with the exception type set to BusinessRuleException and set the 'ContinueOnError' property to True.

Accepted Answer

Store the portal credentials in Orchestrator Assets and configure the MFA code retrieval using a TOTP-based authenticator asset.. Unattended automation that faces MFA must retrieve both the credential and the one-time code programmatically. Orchestrator credential assets protect the password, while a TOTP asset supplies the rotating code. Together they let the robot authenticate without a human, which is the only approach here that satisfies both the unattended schedule and security requirements.

Answer

Use a human-in-the-loop action in Orchestrator to ask an operator to type the MFA code each night.

Answer

Hardcode the username, password, and a static MFA backup code inside the process workflow.

Answer

Disable MFA on the portal account so the robot can log in with only a username and password.

Question 3

An automation developer is using the 'Type Into' activity to enter a date into a web form. The field already contains a placeholder value 'MM/DD/YYYY'. The developer wants to ensure the placeholder is removed before typing the new date. Which property of the 'Type Into' activity should be configured?

Accepted Answer

EmptyField. To ensure the input field is cleared before typing, the EmptyField property must be set to True. This removes any existing content, including placeholders, so the new date is entered cleanly. Other properties like ClickBeforeTyping or Activate only manage focus and do not alter the field's content.

Answer

DelayAfter

Answer

ClickBeforeTyping

Answer

Activate

Question 4

A developer builds a UiPath process that must run unattended on a machine where Microsoft Excel is not installed. The process reads a 200-row spreadsheet, filters rows, and writes a summary sheet. Which activity package and approach should the developer use to meet this requirement without installing Excel?

Accepted Answer

Use the UiPath.Excel.Activities package with Workbook activities such as Read Range Workbook and Write Range Workbook.. Workbook activities use the OpenXML SDK to read and write .xlsx files directly, so they function on robots where Excel is not installed. This makes them the correct choice for unattended processes on locked-down or server machines. Application Scope activities depend on Excel COM, while cloud and database packages address entirely different data sources than a local spreadsheet file.

Answer

Use the UiPath.Excel.Activities package with classic Excel Application Scope and Read Range activities.

Answer

Use the UiPath.MicrosoftOffice365.Activities package with Get Mail and Excel Online activities.

Answer

Use the UiPath.Database.Activities package with Execute Query against the spreadsheet using an OLEDB connection string.

Question 5

A developer needs to extract text from a PDF file that contains scanned images. The developer has installed the UiPath.PDF.Activities package and the UiPath.DocumentUnderstanding.Activities package. Which activity should be used to extract text from the scanned PDF?

Accepted Answer

Read PDF With OCR. For scanned PDFs, the Read PDF With OCR activity is the correct choice because it applies OCR to extract text from images. Other activities like Read PDF Text fail on scanned documents, and Get OCR Text requires UI elements. Digitize Document is more complex and intended for structured data extraction.

Answer

Digitize Document

Answer

Read PDF Text

Answer

Get OCR Text

Question 6

An unattended automation processes invoices by opening a legacy desktop application, extracting totals, and entering them into a web portal. The robot runs on a virtual machine with a locked screen. Data extraction succeeds, but UI interactions with the web portal intermittently fail with 'Element not found' errors even though the element exists. Which change is most likely to resolve the intermittent failures while preserving unattended execution?

Accepted Answer

Ensure the robot session is configured so UI automation runs in the active user session, for example by using UiPath Remote Runtime or setting up the machine for unattended UI interaction.. Intermittent element detection on an unattended robot with a locked screen typically stems from the desktop session not being interactive, which prevents proper UI rendering and automation hooks. Running UI automation in an active user session, or using UiPath Remote Runtime for virtualized environments, restores reliable element access. Selector wildcards, disabling readiness waits, and longer timeouts do not fix the underlying session interactivity problem.

Answer

Set the UiPath.UIAutomation.Activities property 'WaitForReady' to 'None' for the web portal activities.

Answer

Change the web portal selectors from dynamic to static by using wildcard characters in the title attribute.

Answer

Increase the TimeoutMS property of the failing web portal activities from 30000 to 120000.

Question 7

A developer is building an unattended automation that must read values from a desktop application whose UI elements change their AutomationId each time the application restarts. The developer has validated that the element's visible label text is stable and unique on the screen. Which selector strategy should the developer apply to make the selector resilient across restarts?

Accepted Answer

Replace the volatile AutomationId attribute in the selector with the stable label attribute (for example aaname) and validate it with the Selector Editor and UI Explorer.. Selectors should rely on attributes that remain constant across sessions. When an AutomationId is regenerated on each launch, it is unsuitable as an anchor, but a stable visible label exposed through attributes such as aaname gives a durable match. Building that selector and confirming it in the Selector Editor or UI Explorer yields resilience without sacrificing specificity, which is the goal for unattended runs.

Answer

Set the Targeting property of the activity to Image and capture a screenshot of the element on first run for later reuse.

Answer

Add the volatile AutomationId to the selector together with a wildcard character so that any value is accepted at match time.

Answer

Dynamically generate the selector at runtime by reading the AutomationId from a configuration asset and injecting it into the Selector property using a variable.

Question 8

A developer is building a REFramework-based process. The transaction data is stored in a Queue named 'Invoices'. During the Process Transaction state, the developer needs to mark a transaction item as Failed with a specific reason so that it will be retried according to the queue's MaxRetryNumber. Which activity and setting should be used inside the Catch block of the Process Transaction state?

Accepted Answer

Use Set Transaction Status with Status set to 'Failed' and provide the exception reason.. Set Transaction Status with a Failed status is the correct way to record an exception against the current queue item while preserving its retry counter. When MaxRetryNumber is configured, Orchestrator re-queues the item for the specified number of attempts. Creating, deleting, or falsely succeeding the item all break the queue's built-in retry and reporting behavior.

Answer

Use Delete Queue Item to remove the failed item and rely on Orchestrator to regenerate it.

Answer

Use Set Transaction Status with Status set to 'Successful' and write the error to a log file.

Answer

Use Add Queue Item to create a new transaction item with the failure details in the reference field.

Question 9

A team is preparing a long-running unattended process that interacts with a browser-based application and a legacy desktop client. Before publishing, they review configuration to reduce failures caused by UI elements not being ready. Which TWO settings or practices should they apply? (Choose two.)

Accepted Answer

Set the WaitForReady property to Interactive or Complete on activities that need the target to be fully rendered before acting.. Robustness against unready UI comes from waiting on conditions and recovering from transient faults, not from fixed pauses or blanket error suppression. Setting WaitForReady so activities wait for a usable target state, and wrapping fragile interactions in a Retry Scope, addresses both the cause and the recovery. Together they keep an unattended run moving without masking real defects.

Answer

Add an Element Exists activity before each interaction to poll for the element and branch on the result.

Answer

Increase the Delay After property on individual activities that follow navigation or window switching.

Answer

Enable the ContinueOnError property on all activities so execution proceeds even when an element is not found.

Question 10

A developer is configuring a UiPath queue to handle transaction items that may fail due to transient network errors. The developer wants to ensure that failed items are retried automatically and that the process can distinguish between business exceptions and application exceptions. (Choose two.)

Accepted Answer

Set the queue's Max Retry Number to a value greater than zero.. Automatic retries for transient failures are controlled by the queue's Max Retry Number, which must be greater than zero. Distinguishing business from application exceptions requires marking validation failures as BusinessException via Set Transaction Status, so Orchestrator does not retry them. Together these settings meet both stated requirements without manual intervention.

Answer

Configure the queue to store all transaction data in the queue item's Specific Data field.

Answer

Set the queue's Auto Retry property to false and handle retries manually in the workflow.

Answer

Enable the queue's Unique Reference property to prevent duplicate items.

Question 11

An automation developer is building a process that must interact with a Java-based application. The UI elements are not reliably detected by the default UiPath selectors, and the developer needs a more robust method to identify and interact with the application's controls. Which UiPath feature should be used to achieve reliable automation of this Java application?

Accepted Answer

Enable the UiPath Java Extension and use the Java Explorer to inspect and generate selectors for the Java application's controls.. The UiPath Java Extension integrates with the Java Access Bridge to expose Java controls to UiPath. This allows the generation of stable selectors that are resilient to UI changes. Using the Java Explorer, developers can inspect the control hierarchy and create reliable automation for Java applications, which is essential when default selectors are insufficient.

Answer

Use Computer Vision activities exclusively, because they do not depend on selectors and can interact with any application regardless of technology.

Answer

Configure the UiPath UIAutomation activities to use the Active Accessibility mode instead of the default UIA mode, because Java applications expose MSAA interfaces.

Answer

Use the Click activity with the 'SimulateClick' property enabled, as this bypasses selector validation and directly invokes the Java control's action.

Question 12

A developer is refactoring a monolithic UiPath sequence into reusable components used by multiple processes. The components must be versioned, shared across teams, and updated without breaking existing consumers. (Choose two.)

Accepted Answer

Publish the components as NuGet packages to Orchestrator's Libraries feed or a custom NuGet feed.. Publishing components as NuGet packages to a Libraries or custom feed, combined with semantic versioning, gives teams centralized, versioned, and safely upgradable reuse. Consumers pin compatible versions and receive fixes without breaking changes. Copying files, using absolute paths, or inlining sequences all create untracked duplicates that drift and multiply maintenance effort across processes.

Answer

Embed the components as inline sequences in every process to avoid external dependencies.

Answer

Copy the .xaml files directly into each consuming project's folder and edit them in place.

Answer

Reference the components by their absolute file path on a shared network drive.

Question 13

A developer needs to extract a specific value from a JSON response returned by an API call. The JSON structure is nested and the developer wants to avoid writing custom string parsing. Which activity should be used?

Accepted Answer

Deserialize JSON activity followed by accessing the resulting JObject properties.. Working with JSON in UiPath is done by deserializing the string into a JObject, which exposes nested properties through a structured object model. This eliminates the need for custom string parsing and is robust against formatting variations. The other options either misidentify the data format or rely on brittle text manipulation.

Answer

Use the HTTP Request activity's built-in JSON path parser to extract the value directly.

Answer

Read Text File activity and then use regular expressions to find the value.

Answer

Deserialize XML activity because JSON is a subset of XML.

Question 14

A developer needs to store a true/false value that indicates whether a transaction was successful. Which variable type should be used in UiPath Studio?

Accepted Answer

Boolean. The Boolean type is designed to store true/false values and integrates seamlessly with UiPath's conditional activities. It provides type safety and allows direct use in logical expressions. Using Boolean for transaction success flags is a best practice that improves readability and reduces the risk of conversion errors.

Answer

Object

Answer

Int32

Answer

String

Question 15

A developer needs to store a single true or false value that indicates whether an invoice was approved. The value will be used in If activities and written to a log. Which variable type should be used in UiPath Studio?

Accepted Answer

Boolean. Boolean is the precise type for a single true or false state such as invoice approval. It works directly in conditions without conversion and logs clearly. Strings and integers can represent the same idea only indirectly and permit invalid values, while Object removes compile-time type safety and forces casts, making Boolean the clean and correct choice.

Answer

Integer

Answer

Object

Answer

String
