UiPath-ADPv1 UiPath (ADPv1) Automation Developer Professional Exam Questions and Answers

The Show Elements button in the Computer Vision wizard is used to highlight all UI elements that have been identified by the Computer Vision analysis. This helps you to see the UI elements that are available for automation and to select the ones that you want to use in your activities. The Show Elements button is located in the top-right corner of the Computer Vision wizard. When you click it, the UI elements are highlighted with different colors and shapes, depending on their type and category. You can hover over each UI element to see its name and properties. You can also use the Filter Elements button to filter out specific UI elements from being processed by the Computer Vision engine.

o retrieve all Outlook emails with the word “UiPath” in the subject, the developer should use the Filter property and the filter schema “@SQL=”“urn:schemas:httpmail:subject”" like ‘%UiPath%’“. The Filter property allows the developer to specify a condition for retrieving the emails based on the email properties. The filter schema is a string that follows the SQL syntax and uses the urn:schemas:httpmail namespace to access the email properties. The subject property is accessed by using “urn:schemas:httpmail:subject”. The like operator is used to match the value of the subject property with a pattern that contains the word “UiPath”. The percent sign (%) is a wildcard that matches any sequence of characters. Therefore, the filter schema “@SQL=”“urn:schemas:httpmail:subject”” like ‘%UiPath%’" will match any email that has the word “UiPath” anywhere in the subject. References: Get Outlook Mail Messages

In UiPath, the Flow Switch activity is commonly used within flowcharts. Its default TypeArgument property is set to Int32, which means it is primarily used to handle integer-based decision branching.

The use of job priorities in unattended automations within UiPath Orchestrator is to determine which processes should be executed first when dealing with multiple jobs. Job priorities are values that can be assigned to jobs or triggers when they are created or edited. The possible values are High, Normal, and Low. Job priorities affect the order in which the jobs are executed by the robots, with higher priority jobs being executed before lower priority jobs. Job priorities can help you to optimize the execution of your unattended automations, especially when you have limited resources or time-sensitive processes. You can also use job priorities to create job dependencies that must be completed before new job execution, by using the Start Job activity with the Wait for completion option and setting the priority of the child job to High. References: [Job Priority], [Start Job]

"Process A":

The process is scheduled to run at 2:00 PM, but due to busy robots, it starts at 2:05 PM.

The Schedule ending of Job execution feature is configured to stop the job after 20 minutes.

Therefore, "Process A" will be stopped 20 minutes after it started, which is at 2:25 PM.

The command in the UiPath installation folder that configures the UIPath.RemoteDebugging.Agent utility on a Windows robot to accept remote debugging requests from Studio is UiPath-RemoteDebugging.Agent.exe enable -port -password -verbose. This command enables the remote debugging agent on the robot machine and sets the port number and the password that are required for the connection. The verbose option enables the logging of the agent activity to the console. The remote debugging agent is a utility that allows you to debug workflows on a remote robot from Studio, by using the Remote Debugging feature. This feature enables you to connect to a remote robot, run the workflow, and inspect the variables and arguments in real time. To use this feature, you need to install the remote debugging agent on the robot machine and configure it with the same port number and password that you use in Studio. References: [Remote Debugging], [Remote Debugging Agent]

An Application Exception typically refers to errors arising from technical issues with applications, such as non-responsiveness or crashes. These exceptions are not related to the logic or data used by the application but are due to the application's functioning itself.

UiPath Integration Service is the component of the UiPath Platform that makes the automation of third-party applications much easier by standardizing authorization and authentication, helping you manage API connections and also allowing faster integration into SaaS platforms1. By using pre-built connectors, the development of automation projects in UiPath Studio is more simple and more consistent, regardless of the third-party applications you are automating1. Some of the advantages of pre-built connectors are:

They enable automation with an out-of-the-box library of connectors for popular applications such as Salesforce, Slack, Microsoft Office 365, SAP, ServiceNow, and Google G Suite23.

They help setting up and managing connections easily with standardized authentication methods such as OAuth 2.0, Basic, API Key, and Custom1.

They enable kicking off automations with server-side triggers or events, such as receiving an email, creating a record, or updating a field1.

They provide curated activities and events (with additional data filters) for ease of use in UiPath Studio1.

They simplify automation design by providing a uniform experience across all Studio designers1.

They integrate across all UiPath Platform product solutions, such as UiPath Orchestrator, UiPath Assistant, UiPath Action Center, and UiPath Apps3.

To ensure that all UI Automation activities within project workflows reference elements from the Object Repository, the 'Object Repository Enforced' option should be set to Yes in the 'UI Automation Modern' tab within the Project Settings window. This setting enforces the use of the Object Repository for UI activities.

The Verify Expression with Operator activity is used to verify an expression by asserting it in relation to a given expression with an operator1. The expressions tested with this activity must be inserted in their respective property fields. In this case, the activity is configured to verify if the expression “1” is equal to the expression “2”. The result of this verification is stored in the Result property, which reflects the state of the verification activity1. If the verification fails, the activity throws a TestingActivitiesException, which is a custom exception type defined by the UiPath.Testing.Activities package2.

The Try-Catch activity is used to catch a specified exception type in a sequence or activity, and either displays an error notification or dismisses it and continues the execution3. The activity has three main sections: Try, Catches, and Finally. The Try section holds the activity or set of activities that could throw an exception. The Catches section indicates the exception type and holds the activity or set of activities to be performed when the specified exception is thrown. The Finally section holds the activity or set of activities to be performed after the Try and Catches blocks are executed, regardless of the result3.

In this scenario, the Verify Expression with Operator activity is placed in the Try section of the Try-Catch activity. The Catches section has two exceptions caught: System.Exception and TestingActivitiesException. The Finally section is empty. During the execution of the sequence, the Verify Expression with Operator activity will throw a TestingActivitiesException, because the expressions 1 and 2 are not equal. The Try-Catch activity will catch this exception and enter the TestingActivitiesException sequence from the Catches section, where the appropriate actions can be performed to handle the error. Therefore, the correct answer is C. The Exception sequence from the Catches block within the Try-Catch activity will be entered first, after the Verify Expression with Operator activity is executed.

The other options are incorrect because:

Option A is incorrect because the Try-Catch activity will execute one of the blocks within the Catches section, depending on the type of exception thrown by the Verify Expression with Operator activity. In this case, the TestingActivitiesException sequence will be executed.

Option B is incorrect because the Finally block within the Try-Catch activity will be executed only after the Try and Catches blocks are executed, not before. The Finally block is used to perform any cleanup or final actions that are needed regardless of the outcome of the Try and Catches blocks3.

Option D is incorrect because the TestingActivitiesException sequence from the Catches block within the Try-Catch activity will be entered second, not first, after the Verify Expression with Operator activity is executed. The first block to be entered is the Try block, where the Verify Expression with Operator activity is placed.

When expanding the functionality of a workflow to compute the sum of three numbers instead of two, and having to update the test data in an Excel file accordingly, you would generally need to:

Open the Excel file that contains the test data.

Add a new column for the third number (e.g., Number3).

Fill in the data for the new column with the appropriate values for the test cases.

Save the Excel file with the updated data.

Refresh or update the data source in the test case to reflect these changes.

This is because "Refresh Test Data" suggests that the test case will re-import or re-read the test data from its source, which in this case is the updated Excel file with the additional Number3 column. "Update Test Data" might also seem appropriate, but it typically refers to a scenario where you need to update the test case's reference to the data, not the structure of the data itself. "Add Test Data" and "Remove Test Data" are not appropriate as they imply adding a new data set or removing an existing one, rather than refreshing or updating the existing data set with the new column.

A tag in a selector is a node that represents a UI element or a container of UI elements. A tag has the following format: . A tag can have one or more attributes that help identify the UI element uniquely and reliably1. For example, the tag  represents the HTML document of a web page opened in Microsoft Edge browser, with the title “Find Unicorn Name”. The attributes app-msedge.exe and title-Find Unicorn Name help distinguish this tag from other HTML documents.

The other options are not tags, but attributes. An attribute is a property of a UI element that has a name and a value. For example, id='selMonth' is an attribute that indicates the ID of a UI element is “selMonth”. Attributes are used inside tags to specify the UI element or container1.

The processing sequence for queue items in UiPath Orchestrator is determined primarily by the deadline and priority of each item. Items with an earlier deadline are processed first. If multiple items have the same deadline, then priority determines the order: High, Normal, then Low.

Following this logic, the processing sequence would be:

1st: Deadline = 10/04/2023 Priority = LowSince this is the only item with the deadline of the current day (assuming today is 10/04/2023), it should be processed first regardless of its priority.

2nd: No deadline Priority = HighAlthough this item has no deadline, its high priority places it next in the sequence after items with a deadline for the current day.

3rd: Deadline = 10/05/2023 Priority = HighThis item is next due to its combination of an imminent deadline and high priority.

4th: Deadline = 10/05/2023 Priority = NormalThis item has the same deadline as the third but a lower priority, so it comes next.

5th: Deadline = 10/06/2023 Priority = HighThis item, while high priority, has the latest deadline, so it is processed last.

So the order would be:

1st: Deadline = 10/04/2023 Priority = Low2nd: No deadline Priority = High3rd: Deadline = 10/05/2023 Priority = High4th: Deadline = 10/05/2023 Priority = Normal5th: Deadline = 10/06/2023 Priority = High

When using the Type Into activity with the Input Method set to Simulate, the 'Alter disabled element' property should be enabled to execute the activity even if the target UI element is deactivated or read-only.

A mock file is a copy of a workflow file that is used for testing purposes, where some activities are replaced by mock activities that simulate the expected behavior1. A mock file can be created by selecting Mock workflow under test in the Create Test Case window2. The mock file is stored in the Project > Mocks folder, and it has the same name as the original workflow file, with the suffix “_mock” added2. For example, if the original workflow file is named “MySequence.xaml”, the mock file will be named “MySequence_mock.xaml”.

When a mock file is created, the changes made in the original workflow file are automatically applied to the mock file when the project is saved2. This means that any new activities or modifications in the original workflow file are reflected in the mock file, except for the activities that are surrounded by mock activities2. The mock activities are not affected by the changes in the original workflow file, and they can only be edited within the mock file2.

Therefore, if you update “MySequence” and add a Log Message activity and a Verify Expression activity, and then save the project, the changes will be applied to the mock file, assuming that the file is closed. This means that the mock file will also have the Log Message activity and the Verify Expression activity added, unless they are inside a mock activity

The value of the qty variable will be 80 after executing the Assign activity. This is because the expression in the Assign activity is using the LINQ methods AsEnumerable, SkipWhile, and Item to access the data in the dt variable. The dt variable is a DataTable that contains the following data:

Item

Quantity

apple

5

banana

10

mango

20

orange

80

grape

40

The AsEnumerable method converts the DataTable into an Enumerable collection of DataRow objects. The SkipWhile method skips the elements of the collection until the condition is false. The condition is a lambda expression that checks if the value of the Item column is equal to “mango”. The (0) indexer returns the first element of the collection after skipping. The Item method accesses the value of the Quantity column of the DataRow. The ToString method converts the value into a string. Therefore, the expression will skip the first three rows of the DataTable and return the value of the Quantity column of the fourth row, which is 80. References: [DataTable.AsEnumerable Method], [Enumerable.SkipWhile Method], [DataRow.Item Property]

A sequential process is a type of process design that executes actions in a straightforward progression without iteration or branching. A sequential process is composed of a series of activities that are executed one after another, from top to bottom, in a linear fashion. A sequential process is best suited for simple scenarios when activities follow each other and there is no need for complex logic or decision making12.

The other options are not appropriate for an automation task that executes actions in a straightforward progression without iteration or branching, because they involve different types of process design that require more complex structures and logic. For example:

A transactional process is a type of process design that executes actions on a set of data items, one at a time, in a loop. A transactional process is composed of a dispatcher that adds data items to a queue, and a performer that processes each data item from the queue and updates its status. A transactional process is best suited for scenarios when activities need to be repeated for each data item and there is a need for reliability and scalability34.

An iterative process is a type of process design that executes actions repeatedly until a certain condition is met or a certain number of iterations is reached. An iterative process is composed of a loop that contains a set of activities and a condition that controls the exit of the loop. An iterative process is best suited for scenarios when activities need to be performed multiple times and there is a need for dynamic control of the execution flow56.

A linear process is not a type of process design, but a term that refers to a process that has a clear start and end point, and a well-defined sequence of steps that lead to a specific outcome. A linear process can be implemented using different types of process design, depending on the complexity and logic of the steps involved7.

Starting with UiPath Studio version 2022.10, dependencies that lack Windows compatibility are marked as unresolved when they are converted in a project. This means that the project cannot be executed until the unresolved dependencies are manually resolved by the developer. This is done to ensure that the project can run on both Windows and Linux platforms without compatibility issues. References: [UiPath Studio Guide - Converting Projects to Linux Compatibility]

To reduce the pace at which the input string characters are typed into the fields using the Hardware Events input method, the developer should modify the Delay between keys property of the Type Into activity. This property specifies the delay time (in milliseconds) between two keystrokes. The default value is 10 milliseconds. The maximum value is 1000 milliseconds. By increasing the value of this property, the developer can slow down the typing speed and avoid any errors or missed characters. For example, if the developer sets the Delay between keys property to 100 milliseconds, the activity will wait for 0.1 seconds before typing each character of the input string. References: [Type Into], [Delay Between Keys]

on the prerequisite for performing Remote Debugging using an Unattended Robot connection:

The prerequisite is that Studio and the remote robot must be connected to the same Orchestrator tenant. This ensures that Studio can communicate with the remote robot for debugging purposes. While having the same version and TCP/IP connectivity is beneficial, the key requirement for remote debugging is the connection to the same Orchestrator tenant.

LINQ (Language-Integrated Query) is a feature of .NET that allows you to write queries to manipulate data from various sources, such as arrays, collections, databases, XML, etc. LINQ can be used in UiPath Studio to perform complex data operations on variables of different types, such as DataTable, List, Array, etc. LINQ has two syntax forms: query syntax and method syntax. Both forms can achieve the same results, but they have different styles and preferences.

Option B is the correct answer because it demonstrates using LINQ method syntax to filter DataTable rows based on a specific condition. The expression dataTable.AsEnumerable().Where(Function(row) row(“ColumnName”).ToString.Contains(“Value”)).CopyToDataTable() does the following:

It converts the DataTable variable dataTable to an IEnumerable(Of DataRow) object using the AsEnumerable extension method1. This allows the use of LINQ methods on the DataTable.

It filters the rows of the DataTable based on a lambda expression using the Where extension method2. The lambda expression Function(row) row(“ColumnName”).ToString.Contains(“Value”) returns true for the rows that have the value “Value” in the column named “ColumnName”.

It converts the filtered IEnumerable(Of DataRow) object back to a DataTable using the CopyToDataTable extension method3. This returns a new DataTable that contains only the rows that match the condition.

The other options are incorrect because:

Option A is incorrect because it uses an invalid LINQ method Concatenate. The correct method to concatenate two strings in a list is Concat4, which takes two IEnumerable(Of T) objects as arguments and returns a new IEnumerable(Of T) that contains the elements from both sources. For example, listOfStrings.Concat(new List(Of String) {“String_1”, “String_2”}).ToList().

Option C is incorrect because it uses an invalid LINQ method ToJSON. There is no such method in the LINQ library that can convert a list of integers to a JSON format. To achieve this, you need to use a JSON serializer, such as Newtonsoft.Json5, which provides methods to convert .NET objects to JSON and vice versa. For example, JsonConvert.SerializeObject(listOfIntegers).

Option D is incorrect because it uses an invalid LINQ method Split. There is no such method in the LINQ library that can split a DataTable into multiple smaller DataTables based on a specific condition. To achieve this, you need to use a group by clause in LINQ query syntax or a GroupBy extension method in LINQ method syntax6, which groups the rows of a DataTable by a key value and returns an IEnumerable(Of IGrouping(Of TKey, TElement)) object. Then, you can use a Select extension method to project each group into a new DataTable using the CopyToDataTable extension method. For example, dataTable.AsEnumerable().GroupBy(Function(row) row(“ColumnName”)).Select(Function(group) group.CopyToDataTable()).ToList().

The Set Transaction Status activity in UiPath Studio is used to set the status of an Orchestrator queue item to Failed or Successful. This activity is usually placed at the end of the Process Transaction state in the REFramework template, after the Try Catch block. The status of the queue item determines whether it will be retried or not.

To retry a queue item, the status needs to be set to Failed. This means that the transaction was not completed successfully, and it needs to be processed again. The number of retries for a queue item depends on the MaxRetryNumber parameter in the Config file of the REFramework. By default, it is set to 2, which means that each queue item can be retried twice before it is marked as permanently failed.

The other options are not valid statuses for the Set Transaction Status activity. Option A is incorrect, because Retried is not a status, but a property of a queue item that indicates whether it has been retried or not. Option C is incorrect, because Abandoned is a status that is automatically assigned by Orchestrator to a queue item that has been in progress for more than 24 hours, and it cannot be retried. Option D is incorrect, because Postponed is a status that is automatically assigned by Orchestrator to a queue item that has a specific start date in the future, and it cannot be retried until that date is reached.

Mock Testing is a concept that allows you to isolate and replace the input part of an attended RPA process, without modifying the original workflow. Mock Testing enables you to create a mock file of your workflow by selecting Mock workflow under test in the Create Test Case window. This creates a copy of your workflow with the name workflowName_mock and stores it in Project > Mocks. This folder mirrors the source workflow file tree structure. In the mock file, you can use the Surround with mock option to insert a mock activity that replaces the original input activity. For example, instead of asking the user to input a specific token, you can use a mock activity that assigns a predefined token value to a variable. This way, you can test the specific function of the process without having to enter the token manually every time. Mock Testing is useful for tests that have permanent effects in production or require special resources1.

The other options are incorrect because:

Option A is incorrect because Application Testing is not a concept that can be used to isolate and replace the input part of an attended RPA process, without modifying the original workflow. Application Testing is a type of testing that focuses on verifying the functionality, usability, performance, and security of an application2.

Option B is incorrect because Data-Driven Testing is not a concept that can be used to isolate and replace the input part of an attended RPA process, without modifying the original workflow. Data-Driven Testing is a type of testing that uses external data sources, such as Excel files or databases, to provide input values and expected results for the test cases3.

Option D is incorrect because RPA Testing is not a concept that can be used to isolate and replace the input part of an attended RPA process, without modifying the original workflow. RPA Testing is a type of testing that involves using robots to automate the testing of other robots or applications.

The Get File/Folder activity from the Microsoft 365 package should be used to retrieve the Driveitem ID for a Sharepoint URL. This activity allows you to get information about a specific file or folder from OneDrive or SharePoint, such as the name, size, ID, URL, etc. You can specify the file or folder to be retrieved by browsing, entering the ID, or entering the URL1.

To get the Driveitem ID for a Sharepoint URL, you need to do the following steps:

Use the Get File/Folder activity and select the Enter Url option in the File or folder to get property.

Enter the Sharepoint URL of the file or folder in the File or folder Url property. For example, 5.

Create a variable of type Microsoft.Graph.DriveItem in the Output property. For example, driveItem.

Use an Assign activity to get the Driveitem ID from the output variable. For example, driveItemId = driveItem.Id.

The other options are not activities that can be used to retrieve the Driveitem ID for a Sharepoint URL, because they either do not have an output property that returns the Driveitem ID, or they do not have an input property that accepts the Sharepoint URL. For example:

The Get Group activity gets information about a specific group from Microsoft 365, such as the name, ID, description, etc. It does not have an output property that returns the Driveitem ID, nor an input property that accepts the Sharepoint URL2.

The Share File/Folder activity shares a file or folder with the specified recipients. It does not have an output property that returns the Driveitem ID, but only the sharing link and the expiration date3.

The Download File activity downloads a file from OneDrive or SharePoint to a local folder. It does not have an output property that returns the Driveitem ID, but only the local path of the downloaded file4.

The purpose of credential stores in UiPath Orchestrator is to securely store sensitive data such as Robot credentials and Credential Assets for use in automation processes. Credential stores are external services that provide encryption and protection for sensitive data. Orchestrator can integrate with various credential stores, such as CyberArk, Azure Key Vault, and HashiCorp Vault, and use them to store and retrieve the credentials for the Robots and the Credential Assets. Credential Assets are global variables that can store passwords, usernames, API keys, and other confidential information. By using credential stores, the developer can ensure that the sensitive data is not exposed or compromised, and that the automation processes can access the data securely and efficiently. References: [Credential Stores], [Credential Assets]

The Object Repository is a feature of UiPath Studio that allows you to store and manage UI elements that are used in your automation projects. You can create and edit UI descriptors for the UI elements, and reuse them across multiple workflows and projects. The Object Repository supports both the default UI framework and the Computer Vision framework for identifying UI elements.

The Computer Vision framework is a technology that uses artificial intelligence and machine learning to analyze the UI of any application and provide reliable selectors for the UI elements. The Computer Vision framework can handle complex and dynamic UIs that are not supported by the default UI framework, such as Citrix, SAP, or PDF applications.

The Capture All Elements feature in Object Repository is a feature that allows you to capture all the available elements of an application using the Computer Vision technology. You can use this feature to quickly and easily create UI descriptors for all the UI elements on the screen, without having to indicate each element individually. You can access this feature by clicking the Capture All Elements button on the Object Repository ribbon tab, or by using the Capture All Elements activity in the workflow.

The Capture All Elements feature has the following benefits:

It saves time and effort by capturing all the UI elements in one go, instead of indicating each element separately.

It ensures consistency and accuracy by using the same Computer Vision technology and selector logic for all the UI elements.

It allows you to edit, rename, or delete the UI descriptors after capturing them, and customize them according to your needs.

It enables you to reuse the UI descriptors across multiple workflows and projects, and share them with other developers.

The correct answer is C. To capture all the available elements of an application using the Computer Vision technology. This statement accurately describes the purpose of the Capture All Elements feature in Object Repository.

The other options are not correct statements. Option A is incorrect, because the Capture All Elements feature does not capture the selected elements of an application, but all the available elements. It also does not capture the elements from multiple screens simultaneously, but only from the current screen. Option B is incorrect, because the Capture All Elements feature does not capture the selected elements of an application, but all the available elements. Option D is incorrect, because the Capture All Elements feature does not capture the elements from multiple screens simultaneously, but only from the current screen.

The states that will be executed without errors when a developer runs a process using the REFramework, with the process utilizing Orchestrator queues and a queue already created with the Name provided and the Auto Retry function disabled, are Initialization, Get Transaction Data, Process Transaction, and End Process. The REFramework is a template that provides a robust and scalable structure for building automation processes. The REFramework consists of four main states: Initialization, Get Transaction Data, Process Transaction, and End Process. The Initialization state is responsible for initializing the application, reading the configuration file, and logging in to the Orchestrator. The Get Transaction Data state is responsible for fetching the next transaction item from the Orchestrator queue and assigning it to the TransactionItem variable. The Process Transaction state is responsible for executing the main logic of the process for the current transaction item. The End Process state is responsible for closing the application, logging out of the Orchestrator, and performing any cleanup actions. If the process utilizes Orchestrator queues and a queue already exists with the Name provided and the Auto Retry function disabled, then the process will be able to execute these states without errors, assuming that there are no other issues or exceptions in the workflow. References: [Robotic Enterprise Framework], [REFramework States]

 UiPath handles different dependency versions for multiple running processes that run at the same time by using the concept of isolation. This means that each running process uses its own required version of the dependency, without affecting or being affected by other processes. This ensures that the processes run smoothly and consistently, regardless of the dependency versions. The isolation is achieved by using the NuGet protocol, which allows the robot to download and store the dependencies in a local cache folder. The robot then loads the dependencies from the cache folder into separate application domains for each process, creating isolated environments for each process. References: [Managing Dependencies], [About the NuGet Protocol]

The LINQ query that can be used to return the maximum total Quantity from the attached table is dt.AsEnumerable. GroupBy(Function(x) x(“Item”).ToString). Max(Function(x) x.Sum(Function(y) Convert.ToInt32(y(“Quantity”).ToString))). This query uses the LINQ methods AsEnumerable, GroupBy, Max, and Sum to manipulate the data in the dt variable. The dt variable is a DataTable that contains the following data:

No.

Item

Quantity

1

apple

10

2

orange

20

3

mango

50

4

kiwi

80

5

pear

1

6

apple

5

7

mango

15

The AsEnumerable method converts the DataTable into an Enumerable collection of DataRow objects. The GroupBy method groups the elements of the collection by the value of the Item column, creating a collection of groups. Each group has a key, which is the Item name, and a list of elements, which are the DataRows that have the same Item value. The Max method returns the maximum value of the collection, based on a selector function. The selector function is a lambda expression that calculates the sum of the Quantity column for each group. The Sum method returns the sum of the elements in a collection, based on a selector function. The selector function is a lambda expression that converts the value of the Quantity column into an integer. Therefore, the query will group the DataRows by the Item name, calculate the total Quantity for each group, and return the maximum total Quantity among the groups. The maximum total Quantity is 80, which corresponds to the group with the key “kiwi”. References: [DataTable.AsEnumerable Method], [Enumerable.GroupBy Method], [Enumerable.Max Method], [Enumerable.Sum Method]

The queue that will be consumed by the robot is QueueB from FolderA. This is because the arguments passed from Orchestrator have priority over the settings from the Config file. Therefore, the value of in_OrchestratorQueueName overrides the value of OrchestratorQueueName, and the value of in_OrchestratorQueueFolder overrides the value of OrchestratorQueueFolder. However, since the value of in_OrchestratorQueueFolder is empty, the default folder where the process is published is used, which is FolderA1.

The other options are not correct, because they do not reflect the values of the arguments passed from Orchestrator. For example:

Option A is incorrect, because the queue name is QueueA, not QueueB.

Option B is incorrect, because the queue folder is Shared, not FolderA.

Option D is incorrect, because the queue folder is Shared, not FolderA.

The statement that is true about the existing UiPath Studio installation packages is that the Attended Robot installation package installs only the UiPath Robot. The UiPath Robot is the component that executes the automation workflows designed in UiPath Studio. The Attended Robot installation package is intended for scenarios where the Robot works on the same machine as a human user and requires human input or supervision. The Attended Robot installation package does not include UiPath Studio or UiPath Assistant. UiPath Studio is the component that allows the developer to design and debug the automation workflows. UiPath Assistant is the component that allows the user to manage and run the automation workflows on their machine. The Unattended Robot installation package and the Automation Developer installation package both include UiPath Studio, UiPath Assistant, and UiPath Robot, but they are intended for different scenarios. The Unattended Robot installation package is for scenarios where the Robot works on a dedicated machine and does not require human input or supervision. The Automation Developer installation package is for scenarios where the developer needs to create and test the automation workflows on their machine. References: [UiPath Installation Guide], [UiPath Robot], [UiPath Studio], [UiPath Assistant]

In UiPath Studio, during debugging when a workflow hits a breakpoint, the developer can assign values to variables using both the Locals Panel and the Immediate Panel. This feature allows for dynamic testing and troubleshooting.

The service mode is recommended for running unattended automations in UiPath. This mode allows robots to run without needing a user to be logged in, making it ideal for unattended scenarios.

The recommended approach for handling tabular data when building a REFramework transactional project in UiPath is to utilize a DataTable variable to store and process the tabular data. A DataTable variable can hold data in a tabular format, with rows and columns, and can be easily manipulated using built-in activities such as Read Range, Write Range, Filter Data Table, For Each Row, etc. A DataTable variable can also be used as the input for the Get Transaction Data state in the REFramework, which retrieves each row of data as a transaction item for processing. References: [UiPath Studio Guide - Data Tables], [UiPath Studio Guide - The REFramework]

A State Machine is a type of automation that uses a finite number of states in its execution. It can go into a state when it is triggered by an activity, and it exits that state when another activity is triggered. A State Machine consists of four primary components:

•States: These are the nodes that represent the possible situations or conditions of the automation. Each state can have one or more activities inside it that define the behavior of the automation in that state. There are two types of states: State and Final State. A State Machine must have one initial state and one or more final states.

•Triggers: These are the events or conditions that cause the automation to enter a state. A trigger can be an activity, a variable, or an argument that is executed or evaluated before entering a state. For example, a Click activity can be a trigger for entering a state that performs some actions after clicking a button.

•Transitions: These are the arrows or branches that connect the states and define the flow of the automation. A transition can have a condition that determines whether the automation can move from one state to another. For example, a Boolean expression can be a condition for a transition that checks if a certain condition is true or false before moving to the next state.

•Actions: These are the activities or sequences that are executed when the automation moves from one state to another. An action can be performed before or after the transition, depending on the type of the transition. For example, a Log Message activity can be an action that logs a message when the automation exits a state.

You can find out more about state machines on the Studio - State Machines - UiPath Documentation Portal or in the official Workflow Foundation documentation.

The CV Screen Scope activity is used to initialize the UiPath Computer Vision neural network and provide a scope for all subsequent Computer Vision activities. It allows you to select which OCR engine you want to use for scraping the text in the target application. The default OCR engine used for this activity is UiPath Screen OCR, which is an in-house, machine-learning based OCR targeted for screens and digital text. It can be used as an alternative to the other OCR engines, such as Google OCR, Microsoft OCR, or Tesseract OCR. The engine can be changed by manually replacing the default engine with one of your choice1.

The other options are incorrect because:

Option B is incorrect because Microsoft OCR is not the default OCR engine used in CV Screen Scope. Microsoft OCR is an OCR engine that uses the MODI (Microsoft Office Document Imaging) Library to process images and extract text2.

Option C is incorrect because Tesseract OCR is not the default OCR engine used in CV Screen Scope. Tesseract OCR is an OCR engine that uses the open-source Tesseract library to process images and extract text3.

Option D is incorrect because Microsoft Azure Computer Vision OCR is not the default OCR engine used in CV Screen Scope. Microsoft Azure Computer Vision OCR is an OCR engine that uses the Microsoft Azure Computer Vision API to process images and extract text4.

The Get Text activity in UiPath Studio is used to extract and copy the text from a UI element. It has a property called Scraping method, which allows you to choose the method of scraping text from the target element. The available methods are Default, Text attribute, Full text, and Native.

The Default method tries all the other methods and chooses the best one automatically. The Text attribute method uses the text value of the target element as the output. The Native method uses the native method of the application to scrape the text, and allows formatting and screen coordinates to be retrieved. The Full text method uses an OCR engine to scrape the text, and offers the option to Ignore hidden text, which can be activated by selecting its respective check box.

To capture hidden text from an application, the Full text method with the Ignore hidden text option enabled should be used. This way, the Get Text activity can retrieve the text that is not visible on the screen, but is present in the UI element. For example, this method can be used to get the text from a combo box that has more items than the ones displayed, or from a terminal window that has more editable text than the ones shown.

In the REFramework (Robotic Enterprise Framework), the initialization of all required applications should ideally be done in the 'InitAllApplications.xaml' file. This helps in keeping the project organized and maintains a standard structure.

When starting a job manually in UiPath Orchestrator, the default priority value for the Job Priority field is Inherited. This means that the job inherits the priority value that was set at the process level when the package was deployed. The possible priority values are High, Normal, and Low. The priority value determines the order in which the jobs are executed by the robots, with higher priority jobs being executed first. The priority value can be changed manually when starting a job, or it can be set dynamically using the Start Job activity in a workflow. References: [Starting a Job], [Job Priority]

The workflow in question uses a 'Verify Control Attribute' activity to check if the text value of a UI element is equal to "Work Items". The Get Text activity is used to retrieve the text from the specified UI element, and the result of this activity is compared against the expected value "Work Items".

From the provided information, the 'Verify Control Attribute' activity has been set up with the Expression "Work Items" and the Operator set to Equality. The 'Get Text' activity is configured to extract the text from the UI element with the visible text "Work Items", as indicated by the selector shown in the image.

Since the actual value of the UI element's text is "Work Items" (which matches the expected value in the 'Verify Control Attribute' activity), and provided that the 'Get Text' activity successfully retrieves this value, the verification will pass. The configuration indicates that the activity should take a screenshot only if the verification fails (TakeScreenshotIfFailed is set to True), which will not be the case here.

Therefore, assuming that there are no other issues such as incorrect selectors or unexpected changes to the UI element at execution time, the result of the 'Verify Control Attribute' activity will be a pass.

The correct order of actions in the Get Transaction Data state is:

Remove the Get Transaction Item activity from the GetTransactionData workflow.

Add a Read Range activity in the GetTransactionData workflow to read the data from a local Excel file.

Add the logic required to read the data source only one time.

Add the logic required to retrieve only one row from read data each time.

Add the logic required to check if all rows/transaction items from the read data have been processed.

This sequence ensures that the data is read once, processed row by row, and checks for completion.

The correct syntax for using the Vb.Net If operator is If(condition1, valueIfTrue, valueIfFalse). The If operator is a ternary operator that returns one of two values, depending on whether the condition is true or false. The condition must be a Boolean expression or a data type that can be implicitly converted to Boolean. The valueIfTrue and valueIfFalse arguments can be any data type, but they must be the same or implicitly convertible to a common type. The If operator uses short-circuit evaluation, which means that it only evaluates the argument that corresponds to the result of the condition. For example, the following expression returns “Positive” if the variable number is greater than or equal to zero, and “Negative” otherwise:

VB Dim result As String = If(number >= 0, “Positive”, “Negative”) References: [If Operator], [Ternary Operator]

The best practice for creating a repetitive process in the REFramework and defending against potential robot crashes such as “out of memory” is to mark all “Invoke Workflow File” activities from the Main.xaml file with the Isolated option. The Isolated option enables the workflow to run in a separate process, which reduces the memory consumption and the risk of memory leaks. It also improves the stability and the performance of the robot, as it isolates the errors and the exceptions that might occur in the invoked workflow. The Isolated option can be found in the Properties panel of the “Invoke Workflow File” activity, under the Options category. By marking all the invoked workflows as Isolated, the developer can ensure that the robot can handle a large number of transactions without crashing or slowing down

The Type Into activity is used to send keystrokes to a UI element, such as a text box1. The activity has several properties that can be adjusted to achieve different behaviors and results1. One of these properties is the Activate property, which determines whether the specified UI element is brought to the foreground and activated before the text is written1. By default, this property is not selected, which means that the activity will type into the current active window1. However, if the property is selected, the activity will first make sure that the target UI element is visible and focused, and then type the text1. Therefore, if the automation process requires each field to be brought to the foreground, the Activate property of the Type Into activity should be adjusted to achieve this

The collection variable type that will cause an error when adding a new filename to the collection is System.Array. This is because System.Array is a fixed-size collection that cannot be resized or modified once it is initialized. Therefore, if the collection is initialized with a single filename, it cannot accommodate any more filenames. To add a new filename to the collection, the developer should use a dynamic collection type, such as System.Collections.Generic.List or System.Data.DataTable, that can grow or shrink as needed. Alternatively, the developer can use System.Collections.Generic.Dictionary if the filenames need to be associated with some keys or values. References: [Array Class], [Collection Classes]

The Today property of the DateTime structure returns the current date with the time component set to zero1. The Subtract method of the DateTime structure returns a new DateTime object that is the result of subtracting a specified time interval from this instance2. The TimeSpan structure represents a time interval that can be expressed in days, hours, minutes, seconds, and milliseconds3.

Option D is the correct way to subtract a specific TimeSpan from Today in VB.NET. For example, the following code snippet subtracts one day and two hours from the current date and displays the result:

Dim ts As New TimeSpan (1, 2, 0, 0) ' One day and two hours

Dim result As DateTime = Today.Subtract (ts) ' Subtract from Today

Console.WriteLine (result.ToString ("d")) ' Display the result

Option A is not valid, because there is no SubtractSpanFrom method in the DateTime structure. Option B is not correct, because it subtracts the TimeSpan from the current date and time, not just the date. Option C is not valid, because there is no SubtractUsingDate method in the DateTime structure.

The Verbose logging level includes the following information by default:

Execution Started log entry - generated every time a process is started.

Execution Ended log entry - generated every time a process is finalized.

Transaction Started log entry - generated every time a transaction item is obtained by the robot from Orchestrator.

Transaction Ended log entry - generated every time the robot sets the transaction status to either Success or Failed.

Activity Information log entry - generated every time an activity is started, faulted or finished inside a workflow.

Arguments and Variables Information log entry - show values of the variables and arguments that are used.

The Verbose logging level is the most detailed one and it is useful for debugging purposes, as it provides a lot of information about the execution flow and the data used by the robot. However, it also generates a lot of log entries, which can affect the performance and the storage space of the robot and Orchestrator. References: [Logging Levels]

In the InitAllSettingsTestCase test case, one of the verifications that can be done is to check if a certain key is present in the 'Config' dictionary. This ensures that necessary configurations are available for the process.

To replace the functionality of the MessageBox with a LogMessage during mock testing, the developer can perform the action of Surround activity with mock. This action inserts a mock activity around the selected activity, which allows the developer to change the behavior of the activity for testing purposes. For example, the developer can right-click on the MessageBox activity and select Surround activity with mock from the dropdown menu. This will create a mock activity that contains the MessageBox activity. The developer can then edit the mock activity and replace the MessageBox activity with a LogMessage activity, which will write the message to the output panel instead of displaying it in a dialog box. This way, the developer can test the functionality of the workflow without having to interact with the MessageBox dialog box. References: [Mock Testing], [Surround Activity with Mock]
