NEW QUESTION # 40
A Mule project contains a DataWeave module like WebStore.dwl that defines a function named loginUser.
The module file is located in the project's src/main/resources/libs/etl folder.
What is correct DataWeave code to import all of the WebStore.dwl file's functions and then call the loginUser function for the login "Todd.Pal@mulesoft.com"?
Answer: B
Explanation:
* To use custom modules, you need to import the module or functions you want to use by adding the import directive to the head of your DataWeave script, for example:
1) Does not identify any functions to import from the String module:
import dw::core::Strings
2) To identify a specific function to import from the String module:
import camelize, capitalize from dw::core::Strings
3) To import all functions from the String module:
import * from dw::core::Strings
The way you import a module impacts the way you need to call its functions from a DataWeave script. If the directive does not list specific functions to import or use * from to import all functions from a function module, you need to specify the module when you call the function from your script.
* In given scenario, it's mentioned to import all of the WebStore.dwl
So correct answer is:

NEW QUESTION # 42
Refer to the payload.
The Set payload transformer sets the payload to an object. The logger component's message attribute is configured with the string "Result #["INFO"++ payload]" What is the output of logger when this flow executes?
Answer: B
Explanation:
Correct answer is as below as concatenation operation works only with string and not with the objects. In this case payload is object.
"You called the function '++' with these arguments:
1: String ("INFO")
2: Object ({student: {name: "Anay" as String {class: "java.lang.String"},age
NEW QUESTION # 43
Refer to the exhibits.
The Validation component in the Try scope throws an error.
What response message is returned to a client request to the main flow's HTTP Listener?
The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow's HTTP Listener?
Answer: D
Explanation:
Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scope which sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success - main flow.
Hence correct answer is Success - main flow
1) HTTP listener received request
2) The Flow Reference calls the child flow
3) The Is Number validator creates an Error Object because the payload isn't an integer. Child Flow execution stops
#[error.description] = "payload is not a valid INTEGER value"
#[error.errorType] = VALIDATION:INVALID_NUMBER
4) The On Error Continue handles the errorThe payload is set to "Error - Sub Flow"
5) "Error - Sub Flow" is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to "Success - Finished Main Flow"
6) "Success - Main Flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200 As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.
