QUESTION: 37

A developer intends to enter text into an input field using a combination of a string and a hotkey. The input action should take place within a hidden or minimized window.
Which input method(s) can be used individually for the Type Into activity?

Simulate only.
Simulate and Window Messages.
Same as App/Browser and Simulate.
Window Messages only.

Answer(s): B

Explanation:

The Type Into activity is used to enter text in a specified UI element, such as a text box. It has three input methods that can be selected from the properties panel: Default, Simulate, and Window Messages. Each input method has different advantages and limitations, depending on the target application and the automation scenario.
The Default input method uses the hardware driver to simulate the keystrokes, as if a human user is typing on the keyboard. It is the most reliable and compatible input method, but it requires the target application to be in focus and visible on the screen. It also supports sending special keys, such as Tab or Enter, using brackets [k(enter)] or [k(tab)]. The Simulate input method uses the technology of the target application to directly inject the text into the UI element. It does not rely on the hardware driver, so it can work in the background, even if the target application is hidden or minimized. It also supports sending special keys using brackets [k(enter)] or [k(tab)]. However, it may not be compatible with some applications or UI elements that do not support this method.
The Window Messages input method uses the Windows API to send messages directly to the target application. It can also work in the background, even if the target application is hidden or minimized. It does not support sending special keys using brackets [k(enter)] or [k(tab)], but it can send them using modifiers such as {ENTER} or {TAB}. However, it may not be compatible with some applications or UI elements that do not accept window messages.
Therefore, if a developer intends to enter text into an input field using a combination of a string and a hotkey, and the input action should take place within a hidden or minimized window, they can use either the Simulate or the Window Messages input method individually for the Type Into activity. They cannot use the Default input method, because it requires the target application to be in focus and visible on the screen. They also cannot use the Same as App/Browser input method, because it is not an option for the Type Into activity.

QUESTION: 38

Following UiPath best practices, which project structure is best-suited for complex processes in UiPath Studio?

State Machine
Global Exception Handler
Sequence
Flowchart

Answer(s): A

Explanation:

According to the UiPath documentation and best practices, the State Machine project structure is best-suited for complex processes that involve multiple states and transitions between them. A State Machine workflow can model the behavior of a system in terms of states, such as "Init", "Get Transaction Data", "Process Transaction", and "End Process", and transitions, such as "Success", "Business Rule Exception", or "System Error". A State Machine workflow can also have entry and exit actions for each state, which are activities that execute when the system enters or exits the state, respectively.
A State Machine project structure has several advantages over other project structures, such as Sequence, Flowchart, or Global Exception Handler, for complex processes2:
It can handle complex logic and branching conditions more easily and clearly than a Sequence or a Flowchart, which can become cluttered and hard to maintain for large processes. It can handle exceptions and errors more efficiently and consistently than a Global Exception Handler, which is a separate workflow that handles all exceptions in a project. A State Machine can have dedicated states and transitions for handling different types of exceptions, such as business rule exceptions or system errors, and can also use retry mechanisms or recovery actions. It can improve the readability, modularity, and reusability of the workflows, by breaking down the process into smaller and coherent states that can be invoked from the main workflow. This also facilitates collaboration and testing among developers. Therefore, a State Machine project structure is best-suited for complex processes that involve multiple states and transitions between them.

QUESTION: 39

A developer configured the properties for a Click activity on an element inside a web page as shown in the following exhibit.

An animation on the web page never completely loads but the element indicated in the Click activity does load within the specified timeout duration.
What occurs when this Click activity executes?

Element is clicked once the element is fully loaded.
Timeout error occurs without clicking on the element.
Waits 10 seconds before clicking on the element.
Continues to the next activity after 30 seconds without clicking on the element.

Answer(s): A

Explanation:

The Click activity is used to simulate a mouse click on a specified UI element, such as a button or a link. It has several properties that can be configured to customize its behavior, such as the input method, the click type, the timeout, and the wait for ready. The input method determines how the click is performed. It can be Default, Simulate, or Window Messages. The Default method uses the hardware driver to simulate the click, and it requires the target element to be visible and in focus. The Simulate and Window Messages methods use the technology of the target application to inject the click, and they can work in the background, even if the target element is hidden or minimized.
The click type determines which mouse button is used for the click. It can be Single, Double, Down, or Up. The Single and Double types perform a single or double click using the left mouse button. The Down and Up types perform a press or release action using any mouse button. The timeout determines how long the activity waits for the target element to appear before throwing an error. It is measured in milliseconds, and it has a default value of 30000 (30 seconds). If the timeout is exceeded, the activity fails with a TimeoutException. The wait for ready determines when the activity executes. It can be None, Interactive, or Complete. The None option executes the activity immediately. The Interactive option executes the activity after the target element is loaded. The Complete option executes the activity after the target application is loaded.
In your case, you have configured the properties for the Click activity as follows:
Input method: Simulate
Click type: Single
Timeout: 30000
Wait for ready: Complete
This means that the Click activity will use the Simulate method to perform a single click on the target element in the background, after waiting for 30 seconds or until the target application is fully loaded, whichever comes first.
Since you have mentioned that an animation on the web page never completely loads but the element indicated in the Click activity does load within the specified timeout duration, what occurs when this Click activity executes is:
Element is clicked once the element is fully loaded.
This is because the Simulate method can work in the background, even if the web page is hidden or minimized, and it does not depend on the animation to complete. The Complete option for wait for ready ensures that the Click activity waits until the target element is loaded before clicking on it. The timeout value of 30000 does not affect this scenario, because it is not exceeded.
Therefore, option A is correct.

QUESTION: 40

When encountering an ApplicationException, what occurs if the developer chooses InvalidOperationException as the exception handler within the Catches section of the Try Catch activity?

The Finally block is executed and the Catches section catches the exception.
A runtime error occurs and the Finally block is not executed.
No exceptions are happening and the workflow continues to execute.
No exception is thrown and the Finally block executes.

Answer(s): B

Explanation:

The Try Catch activity is used to handle errors and exceptions that may occur during the execution of a workflow. It has three sections: Try, Catches, and Finally. The Try section contains the activities that may throw an exception or an error. If an exception or an error occurs, the execution of the Try section is stopped and the control is passed to the Catches section.
The Catches section contains one or more exception handlers that specify what type of exception or error to catch and what actions to perform when it is caught. The exception handlers are executed in order, from top to bottom, until a matching exception or error is found. If no matching exception or error is found, the execution of the workflow is stopped and a runtime error is thrown. The Finally section contains the activities that are always executed at the end of the Try Catch activity, regardless of whether an exception or error occurred or not. The Finally section is used to perform cleanup actions, such as closing applications, releasing resources, or logging messages. In your case, you have configured the properties for the Try Catch activity as follows:
The Try section contains a Throw activity with an ApplicationException. The Catches section contains an InvalidOperationException with a Message Box activity and a Log

Message activity.
The Finally section is empty.
This means that the Try Catch activity will throw an ApplicationException in the Try section and look for a matching exception handler in the Catches section. However, since you have chosen InvalidOperationException as the exception handler, which does not match the ApplicationException, the execution of the workflow will be stopped and a runtime error will occur. The Finally section will not be executed.
Therefore, option B is correct.
