NEW QUESTION # 38
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 "[email protected]"?
- A. 1. 1. import * from libs::etl::WebStore
2. 2. ---
3. 3. loginUser("[email protected]") - B. 1. 1. import * from libs::etl
2. 2. ---
3. 3. WebStore::loginUser("[email protected]") - C. 1. 1. import libs.etl
2. 2. ---
3. 3. WebStore.loginUser("[email protected]") - D. 1. 1. import libs.etl.WebStore
2. 2. ---
3. 3. loginUser("[email protected]")
Answer: A
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
What MuleSoft API-led connectivity layer is intended to expose part of a backend database without business logic?
- A. Data layer
- B. System layer
- C. Experience layer
- D. Process layer
Answer: B
Explanation:
Correct answer is System layer
System APIs provide a means for insulating the data consumers from the complexity or changes to the underlying backend systems.
MuleSoft recommends three-layered approach to API-led connectivity, highlighting the three layers:
* System APIs
* Process APIs
* Experience APIs
System APIs are the core systems of record underlying core systems of record (e.g. ERPs, key customer and billing systems, databases, etc.). Process APIs allow you to define a common process which the organization can share, and these APIs perform specific functions, provide access to non-central data, and may be built by either Central IT or Line of Business IT. And finally, the Experience APIs are the means by which data can be reconfigured so that it is most easily consumed by its intended audience, all from a common data source.
The three-layered structure allows for a seamless flow of data from systems of record to new experiences, and allows for reusability of assets rather than point to point connections. This approach provides a distributed and tailored approach to architecture, greater flexibility through loose coupling, and deeper operational visibility into what is being built.

NEW QUESTION # 49
Refer to exhibits.
In the execution of the Scatter-Gather , the flow route completes after 10 seconds and the flow2 route completes in 40 seconds. How many seconds does it take for the Scatter-Gather to complete?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Scatter-Gather sends the event to each routes concurrently. Hence both route in this example will start in parallel. So total time to complete processing is 40 seconds The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully.
The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.
