MuleSoft Certified Developer - Level 1 (Mule 4) Sample Questions (Q227-Q232):

NEW QUESTION # 227
Refer to the exhibits.


A web client submits a request to the HTTP Listener and the HTTP Request throws an error.
What payload and status code are returned to the web client?
Refer to the exhibits. A web client submits a request to the HTTP Listener and the HTTP Request throws an error.
What payload and status code are returned to the web client?

Answer: B


NEW QUESTION # 228
Refer to the exhibits.

What payload and variable are logged at the end of the main flow?

Answer: B

Explanation:
Correct answer is [[5, 10, 15, 20], 5]
Key thing to note here is that any changes made to payload in for each loop are not available outside for each scope where as variable value updated in for each loop is visible out side for each loop too.
In this example , sequence can be described as follows
1) Payload is set to the value [5, 10, 15, 20]
2) Variable is set to the value of 1
3) For each loop is executed four times and in each loop payload value is updated to append "Req" and variable is count is increased by 1
4) Once control comes out of for each , payload changes made within for each are not visible. Hence payload at this point of time is equal to payload available before entering for each loop which was [5, 10, 15, 20].
Similarly variable value updated in for each loop is also available outside hence variable value is 5 as it was updated in loop.
5) Hence correct answer is [[5, 10, 15, 20], 5]
For Each Scope
The For Each scope splits a payload into elements and processes them one by one through the components that you place in the scope. It is similar to a for-each/for loop code block in most programming languages and can process any collection, including lists and arrays. The collection can be any supported content type, such as application/json, application/java, or application/xml.
General considerations about the For Each scope:
By default, For Each tries to split the payload. If the payload is a simple Java collection, the For Each scope can split it without any configuration. The payload inside the For Each scope is each of the split elements.
Attributes within the original message are ignored because they are related to the entire message.
For Each does not modify the current payload. The output payload is the same as the input.
For non-Java collections, such as XML or JSON, use a DataWeave expression to split data. Use the Collection field for this purpose.


NEW QUESTION # 229
Refer to the exhibits The Mule application does NOT define any global error handlers.
A web client sends a POST request to the Multi application with this input payload The File Write operation throws a FILECONNECTIVITY error What response message is returned to the web client?

Answer: C


NEW QUESTION # 231
A Mule application contains a global error handler configured to catch any errors.
Where must the global error handler be specified so that the global error handler catches all errors from flows without their own error handlers?

Answer: B

Explanation:
Correct answer is A global element
Global error handlers are to be created in global element .
Quick note to remember here is Global error handlers come in to picture only when there are no error handlers specified as flow level.
Steps to create Global error handler
1) Click Global Elements to open Global Configuration Elements. Global Elements is located below the Studio canvas
2) In Global Configuration Elements, click Create to open the Choose Global Type dialog

3) From the dialog, select Global Configuration - Configuration, and then click OK to open the Configuration dialog.

4) From the select Configuration dialog, select allErrorHandler for the Default Error Handler field, and click OK.
