DataWeave Function Definition Syntax
To define a function in DataWeave use the following syntax:
fun myFunction(param1, param2, ...) = <code to execute>
The fun keyword starts the definition of a function.
myFunction is the name you define for the function.
Function names must be valid identifiers.
(param1, param2, ... , paramn) represents the parameters that your function accepts.
You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.
The = sign marks the beginning of the code block to execute when the function is called.
<code to execute> represents the actual code that you define for your function.

Refer to the exhibits. A web client sends a POST request to the HTTP Listener and the Validation component in the Try scope throws an error.

Refer to the exhibits. Client sends the request to ClientRequestFlow which calls ShippingFlow using HTTP Request activity.
During E2E testing it is found that that HTTP:METHOD_NOT_ALLOWED error is thrown whenever client sends request to this flow.
What attribute you would change in ClientRequestFlow to make this implementation work successfully?
Correct answer is Change the method attributes value to 'POST'.
It can be fixed in either of the two ways as below.
1) Changing method attribute to POST in ClientRequestFlow
2) Setting allowedMethods as PUT in ShippingFlow (but doesn't fit as question mentions about changing ClientRequestFlow)
An SLA based policy has been enabled in API Manager. What is the next step to configure the API proxy to enforce the new SLA policy?
Correct answer is Add required headers to RAML specification and redeploy new API proxy
MuleSoft Doc Ref : https://docs.mulesoft.com/api-manager/2.x/tutorial-manage-an-api
Steps are as below :
Add the Required RAML Snippet
SLA-based rate limiting requires adding a RAML or OAS snippet to your API. This procedure demonstrates adding a RAML snippet.
Specify the client ID and secret as query parameters.
Add a section called traits: at the RAML root level to define query parameters:
traits:
- client-id-required:
queryParameters:
client_id:
type: string
client_secret:
type: string
Add the client-id-required trait to every method that requires these query parameters:
/users:
get:
is: [client-id-required]
description: Gets a list of JSONPlaceholder users.
Step 2 : Add the SLA Tier in API Manager
Step 3 : Apply the policy and redeploy
