Question 2
Salesforce Salesforce-MuleSoft-Developer-I
QUESTION DESCRIPTION:
Refer to the exhibit.
What should be changed to fix the 415 error?
Correct Answer & Rationale:
Answer: C
Explanation:
The HTTP 415 Unsupported Media Type client error response code indicates that the server refuses to accept the request because the payload format is in an unsupported format. The format problem might be due to the request ' s indicated Content-Type or Content-Encoding , or as a result of inspecting the data directly. In this case as per RAML specification data is expected in application/json and in request Content-Type is set as " text/plain " which is incorrect. Hence solution is set the request Content-Type header to application/json

Question 6
Salesforce Salesforce-MuleSoft-Developer-I
QUESTION DESCRIPTION:
A Utlility.dwl is located in a Mule project at src/main/resources/modules. The Utility.dwl file defines a function named encryptString that encrypts a String What is thecorrect DataWeave to call the encryptString function in a Transform Message component?
Correct Answer & Rationale:
Answer: B
Explanation:
Correct answer is
%dw 2.0
output application/json
import modules::Utility
---
Utility::encryptString( " John Smith " )
DataWeave 2.0 functions are packaged in modules. Before you begin, note that DataWeave 2.0 is for Mule 4apps. For Mule 3 apps, refer to DataWeave Operators in the Mule 3.9 documentation. For other Mule versions, you can use the version selector for the Mule Runtime table of contents.
Functions in the Core (dw::Core) module are imported automatically into your DataWeave scripts. To use other 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:
import dw::core::Strings
import camelize, capitalize from dw::core::Strings
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. For example, this import directive does not identify any functions to import from the String module, so it calls the pluralize function like this: Strings::pluralize( " box " ).
Transform
%dw 2.0
import dw::core::Strings
output application/json
---
{ ' plural ' : Strings::pluralize( " box " ) }
Question 7
Salesforce Salesforce-MuleSoft-Developer-I
QUESTION DESCRIPTION:
Refer to the exhibits.
What DataWeave expression transforms the conductorIds array to the XML output?
Correct Answer & Rationale:
Answer: C
Explanation:
Points toremember:
* XML must have a root element.
* XML only allows one root element
* To avoid multiple root issues, you must create a root element for the XML output, whenever we transform output
* When mapping array elements (JSON or JAVA) to XML, wrap the mapoperations in {(..)}
-{ } are defining the object
( ) are transforming each element in the array as a key/value pair
* The transformation to XML would fail if the above mentioned considerations were not taken into account.
* Thus the transformation scriptdeclares a root element as trains and wraps the data in “{( )}“.
Whenever you see such type of question, always look out for root element followed by {( )} wrapping map.
I call this a " Wrap The Map " scenario. Hope it would help you remember !
Question 8
