Correct answer is Mule runtime

DataWeave is the MuleSoft expression language for accessing and transforming data that travels through a Mule app. DataWeave is tightly integrated with the Mule runtime engine, which runs the scripts and expressions in your Mule app.

Mule Doc Reference : https://docs.mulesoft.com/mule-runtime/4.3/dataweave

Database always return rows as an array.

Array is the correct answer

String is the correct answer as XML is of an Object type String

Returns an array that is the result of applying a transformation function (lambda) to each of the elements.

MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/dataweave-cookbook-map

Themap operator is a function in Dataweave which iterates over the items in an array and outputs them into a new array. It basically accepts input as a list of items in an array and manipulates the items in the array in order to form a new array as an output.

Correct answer is as below. Attributes in the incoming xml payload are always accessed using @.Similarly *item is requiredas we have multiple items in the request

%dw 2.0

output application/csv

---

payload.sale.*item map ((value, index) -> {

index: index,

sale: value.@saleId,

itemName: value.desc,

itemPrice: (value.quantity) * (value.price),

item: value.@itemId

} )

QUESTIONNO: 96

Refer to the exhibits.

The main flow contains a Flow Reference to the child flow.

A web client sends a GET request to the main flow's HTTP Listener that includes a make query parameter.

What values are accessible in the child flow?

A. payload

B.payload

make query param

C. payload

model var

D. payload

make query param model var

Answer: D

Correct answer is Validation modules Is Number operation.

Mule 4 does not use filters anymore. The functionality provided by filters in Mule 3 can be achieved by using the Validation Module.

Paths

The pathof an HTTP listener can be static, which requires exact matches, or feature placeholders. Placeholders can be wildcards (*), which match against anything they are compared to, or parameters ({param}), which not only match against anything but also capturethose values on a URI parameters map.

Take the following example paths for three listeners using a configuration that establishes api/v1 as the base path:

account/mulesoft/main-contact: only match the exact path request http://awesome-company.com/api/v1/account/mulesoft/main-contact

account/{accountId}/main-contact: matches all path requests structured similarly, such as http://awesome-company.com/api/v1/account/salesforce/main-contact, and save salesforce as the value of accountId.

account/{accountId}/*: matches all path requests different from main-contact, such as http://awesome-company.com/api/v1/account/mulesoft/users, and save mulesoft as the value of accountId.

Correct answer is Publish the API to Anypoint Exchange

Anypoint Exchange makes this possible bymaking it discoverable in below ways

1) In private exchange for internal developers

2) In a public portal for external developers/clients
