QUESTION: 57

In the context of the REFramework, if the OrchestratorQueueName key is present in both the Settings and Assets sheets, but an asset with the corresponding name is not present in Orchestrator, what will be the behavior at run time?

The flow will throw an exception in InitAllSettings workflow.
The flow will use the value from the Settings sheets since the asset is missing.
An empty string will be saved for the "OrchestratorQueueName" key in the config dictionary.
The "OrchestratorQueueName" key is not added to the config dictionary and the flow will throw in Get Transaction Data workflow.

Answer(s): B

Explanation:

The REFramework template is a robust and scalable framework for building RPA projects. It uses a config file to store the settings and constants that are used throughout the project. The config file has two sheets: Settings and Assets. The Settings sheet contains the key-value pairs that are read by the InitAllSettings workflow and stored in the config dictionary. The Assets sheet contains the names of the assets that are stored in Orchestrator and need to be retrieved by the InitAllApplications workflow. The OrchestratorQueueName key is used to specify the name of the queue that is used to store the transaction items for the process. If the OrchestratorQueueName key is present in both the Settings and Assets sheets, but an asset with the corresponding name is not present in Orchestrator, the behavior at run time will be as follows:
The InitAllSettings workflow will read the value of the OrchestratorQueueName key from the Settings sheet and store it in the config dictionary.
The InitAllApplications workflow will try to retrieve the asset with the name OrchestratorQueueName from Orchestrator using the Get Asset activity. Since the asset does not exist, the activity will throw an exception.
The exception will be caught by a Try Catch block and handled by a Log Message activity with level Warning and message "Asset not found: OrchestratorQueueName". The flow will continue with the next asset in the Assets sheet or move to the next state if there are no more assets.
The flow will use the value of the OrchestratorQueueName key from the config dictionary whenever it needs to access or update the queue.
Therefore, option B is correct. Option A is incorrect because the exception is thrown in InitAllApplications workflow, not InitAllSettings workflow. Option C is incorrect because an empty string is not saved for the OrchestratorQueueName key in the config dictionary. Option D is incorrect because the OrchestratorQueueName key is added to the config dictionary and the flow does not throw in Get Transaction Data workflow.

QUESTION: 59

A developer wants to add items to a list of strings using the Invoke Method activity. The list is declared as follows:

The Invoke Method includes the following properties:

The Parameters property is as follows:

Based on the exhibits, what is the outcome of this Invoke Method activity?

Invoke Method activity will throw an error.
Colors will contain items in the following order: "Yellow", "Red", "Green".
olors will contain items in the following order: "Red", "Green", "Yellow".
Colors will contain items in the following order: "Red", "Green".

Answer(s): C

Explanation:

The Invoke Method activity is used to execute a method of a class or an object. In this case, the developer wants to add items to a list of strings using the Add method of the List class. The list is declared as Colors and initialized with two items: "Red" and "Green". The Invoke Method activity has the following properties:
TargetObject: Colors (the list variable)
MethodName: Add (the method of the List class)
Parameters: Direction - In, Type - String, Value - "Yellow" (the item to be added to the list) Based on these properties, the Invoke Method activity will add the string "Yellow" to the end of the Colors list. Therefore, the outcome of this Invoke Method activity is that Colors will contain items in the following order: "Red", "Green", "Yellow".
Option A is incorrect because the Invoke Method activity will not throw an error, as the properties are configured correctly. Option B is incorrect because the order of the items in the list will not change, as the Add method appends the item to the end of the list. Option D is incorrect because the list will have three items, not two, as the Add method does not overwrite any existing item.

QUESTION: 60

A developer needs to use the REFramework to automate a business process that involves processing transactions within an Excel table. Each transaction in the table should follow the same steps for processing and queues cannot be used as there is no Orchestrator in the environment.
Which variable type is best suited for Transactionltem in this scenario?

System.Data.DataRow
UiPath.Core.Queueltem
System.Data. DataTable
System.Data.DataRow[]

Answer(s): A

Explanation:

The REFramework template is a robust and scalable framework for building RPA projects. It uses a state machine to handle the different stages of the automation process. One of the states is the Process Transaction state, where the main actions are performed on each transaction item. A transaction item can be a queue item from Orchestrator, a data row from an Excel file, or any other type of data that needs to be processed. If the transactions are stored in an Excel table, the best variable type for TransactionItem is System.Data.DataRow, as it represents a single row of data in a DataTable. A DataTable is a collection of rows and columns that can be read from or written to an Excel file using the Excel activities. Therefore, option A is correct. Option B is incorrect because UiPath.Core.QueueItem is a variable type that represents an item from a queue in Orchestrator. If there is no Orchestrator in the environment, queues cannot be used and QueueItem is not applicable. Option C is incorrect because System.Data.DataTable is a variable type that represents a table of data with rows and columns. A single transaction item cannot be a whole table, but only a row from the table. Option D is incorrect because System.Data.DataRow[] is a variable type that represents an array of data rows. An array is a collection of items of the same type that can be accessed by an index. A single transaction item cannot be an array, but only an element from the array.
