A mule project contains MySQL database dependency . The project is exported from Anypoint Studio so that it can be deployed to Cloudhub.
What export options needs to be selected to create the smallest deployable archive that will successfully deploy to Cloudhub?
- A . Select both the options 1) Attach project sources 2) Include project module and dependencies
- B . No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies
- C . Select only below option 2) Include project module and dependencies
- D . Select only below option 1) Attach project sources
C
Explanation:
You can choose Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. But requirement here is to create smallest deployable archive that will successfully deploy to Cloudhub. Hence we can ignore this option. We need to select Include project module and dependencies
As actual modules and external dependencies required to run the Mule application in a Mule runtime engine
Hence correct answer is Select only below option 2) Include project module and dependencies

What is output of Dataweave flatten function?
- A . Object
- B . Map
- C . Array (Correct)
- D . LInkedHashMap
C
Explanation:
Correct answer is Array.
Flatten turns a set of subarrays (such as [ [1,2,3], [4,5,[6]], [], [null] ]) into a single, flattened array (such as [ 1, 2, 3, 4, 5, [6], null ]).
This example defines three arrays of numbers, creates another array containing those three arrays, and then uses the flatten function to convert the array of arrays into a single array with all values.
Source
%dw 2.0
output application/json
var array1 = [1,2,3]
var array2 = [4,5,6]
var array3 = [7,8,9]
var arrayOfArrays = [array1, array2, array3]
—
flatten(arrayOfArrays)
Output
[ 1,2,3,4,5,6,7,8,9 ]

What MuleSoft API-led connectivity layer is intended to expose part of a backend database without business logic?
- A . Data layer
- B . Process layer
- C . Experience layer
- D . System layer
D
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.

Mule application contains ActiveMQ JMS dependency. Mule application was compiled and run successfully in Anypoint Studio. The mule application must now be exported from Anypoint Studio and shared with other developer.
What export options should be selected to create the smallest JAR file that can be imported into other developer’s Anypoint Studio and run successfully?
- A . Select only Attach Project Sources only
- B . Select both Attach Project Sources and Include project modules and dependencies option
- C . Select the Include project modules and dependencies option only
- D . De-select both Attach Project Sources and Include project modules and dependencies option
A
Explanation:
Correct answer is Select only Attach Project Sources only
You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace.
Deselect the Include project modules and dependencies option.
This option skips bundling the actual modules and external dependencies required to run the Mule application in a Mule runtime engine, creating a lightweight JAR file package that does not include any dependencies specified in the Mule application’s pom.xml file.
The generated JAR file is not a functional deployable archive and cannot be deployed to a Mule runtime engine, but instead offers a way to archive only the source files that make up the Mule application. This is the same as using the -lightWeightPackage flag when
packaging using the Mule Maven Plugin and is useful if you want to distribute your project to other Studio installations because it only keeps a reference to all its dependencies. When you import a lightweight package into Studio, all your dependencies are automatically downloaded MuleSoft Doc

Ref: https://docs.mulesoft.com/mule-runtime/4.3/dataweave-cookbook-map The map 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. I have created below chart for your easier understanding:

What should this endpoint return? http://dev.acme.com/api/patients?name=John&surname=Bell
- A . Patient with name as John
- B . Patient with surname as bell
- C . Patients with either name as John or surname as Bell
- D . Patients with name as John and surname as Bell
D
Explanation:
Query parameters are a defined set of parameters attached to the end of a url. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a ‘?’ Is added followed immediately by a query parameter.
To add multiple parameters, an ‘&’ is added in between each.
Hence coming back to question, endpoint would return Patients with name as John and (and is very important here) surname as Bell
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?
- A . Add new property placeholders and redeploy the API proxy
- B . Add new environment variables and restart the API proxy
- C . Restart the API proxy to clear the API policy cache
- D . Add required headers to the RAML specification and redeploy the new API proxy
D
Explanation:
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

All three of the conditions for the Choice router are true.
What messages are written in the application log?
- A . Route1
- B . Route2
- C . Route1, Route2
- D . Route1, Route2, Default
A
Explanation:
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route1 execution and the others are not checked. If none of the expressions are true, then the default route executes. Hence only Route1 will be executed as it is the first expression. hence output of logger is Route1.
MuleSoft Doc
Ref: https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route’s execution and the others are not checked. If none of the expressions are true, then the default route executes.

What is the correct syntax for a Logger component to output a message with the contents of a 3SON Object payload?
- A . The payload is: $(payload)
- B . #["The payload is: " ++ payload]
- C . The payload is: #[payload]
- D . #["The payload is: " + payload]
B
Explanation:
Option 3 is the only corect answer as it concatenates payload with String.
Below option wont work.
#["The payload is " ++ payload]
Concatenation function expects both arguments to be string. As the question says payload is json object, this will throw error while running it. You can try this in Anypoint Studio and you will get the same result which I mentioned. hence correct answer is
The payload is: #[payload]
Refer to the exhibit.

A RAML example fragment named StudentExample.raml is placed in the examples folder in an API specification project.
What is the correct syntax to reference the fragment?
- A . examples: !include StudentExample.raml
- B . examples: #import StudentExample.raml
- C . examples: !include examples/StudentExample.raml
- D . examples: #import examples/StudentExample.raml
C
Explanation:
To include property. To keep the API definition concise, you can include external content, such as documentation, schemas, and frequently used patterns outside the definition itself. The parser interprets !include as if the content of the externally-hosted file or a URL were declared in-line.
To use the fragments in RAML you have to include the exact path(copy the path) of that fragment you want to use as shown below
Option 3 is the correct as correct syntax is examples: !include examples/StudentExample.raml

CloudHub Workers
Workers are dedicated instances of Mule runtime engine that run your integration applications on CloudHub. The memory capacity and processing power of a worker depends on how you configure it at the application level.
Worker sizes have different compute, memory, and storage capacities. You can scale workers vertically by selecting one of the available worker sizes:

A web client submits the request to the HTTP Listener.
What response message would be returned to web client?
- A . End
- B . String is not blank
- C . No response would be sent back to client and request will get errored out in Mule
- D . Start
B
Explanation:
Correct answer is String is not blank.
————————————————————————————————————————-
Here’s specifically what is happening here:
1) Payload is successfully set to “Start”
2) The Is Blank String validator creates an Error Object because the payload is string "Start". Execution stops
#[error.description] = “String is not blank”
3) Because no error handler is defined, the Mule default error handler handles the error. Remember, at its heart, the Mule Default Error handler is an error handling scope with just an on error propagate
4) “String is not blank” is the error message returned to the requestor in the body of the HTTP requestHTTP Status Code: 500

A Batch Job scope has five batch steps. An event processor throws an error in the second batch step because the input data is incomplete.
What is the default behavior of the batch job after the error is thrown?
- A . All processing of the batch job stops.
- B . Event processing continues to the next batch step.
- C . Error is ignored
- D . Batch is retried
A
Explanation:
In case of an error, batch job completes in flight steps and stops further processing.
MuleSoft Doc
Ref: Handling Errors During Batch Job | MuleSoft Documentation
The default is all processing will stop but we can change it by Max Failed Record field.
General -> Max Failed Records: Mule has three options for handling a record-level error:
Finish processing, Continue processing and Continue processing until the batch job
accumulates a maximum number of failed records. This behavior can be controlled by Max Failed Records.
The default value is Zero which corresponds to Finish processing.
The value -1, corresponds to Continue processing.
The value +ve integer, corresponds to Continue processing until the batch job accumulates a maximum number of failed records
What module and operation will throw an error if a Mule events payload is not number ?
- A . Filter modules Is Number operation
- B . Validation modules Is Number operation
- C . Validation modules Is not Number operation

An API implementation has been deployed to CloudHub and now needs to be governed. IT will not allocate additional vCore for a new Mule application to act as an API proxy.
What is the next step to preseive the current vCore usage, but still allow the Mule application to be managed by API Manager?
- A . Register the same API implementation in Runtime Manager to connect to API Manager
- B . Modify the API implementation to use auto-discovery to register with API Manager
- C . Upload the Mule application’s JAR file to the API instance in API Manager
- D . Deploy the same API implementation behind a VPC and configure the VPC to connect to API Manager
B
Explanation:
Correct answer is Modify the API implementation to use auto-discovery to register with API Manager
API Autodiscovery
Configuring autodiscovery allows a deployed Mule runtime engine (Mule) application to connect with API Manager to download and manage policies and to generate analytics data. Additionally, with autodiscovery, you can configure your Mule applications to act as their own API proxy.
When autodiscovery is correctly configured in your Mule application, you can say that your application’s API is tracked by (green dot) or paired to API Manager. You can associate an API in a Mule setup with only one autodiscovery instance at a given time.

The web client sends a POST request to the ACME Order API with an XML payload. An error is returned.
What should be changed in the request so that a success response code is returned to the web client?
- A . Set a request header with the name Content-Type to a value of applicatron/octet-stream
- B . Set a request header with the name Content-Type to a value of application/xml
- C . Set a response header with the name Content-Type to a value of applkation/xml
- D . Set a response header with the name Content-Type to a value of application/octet-stream
B
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. As per RAML input is expected in application/xml.
Hence correct answer is Set a request header with the name Content-Type to a
What should this endpoint return considering the API is build using standard practices?
http://dev.acme.com/api/patients?year=2021
- A . Patient with id 2021
- B . Patients from year 2021
- C . No patients
- D . All patients
B
Explanation:
Correct answer is Patients from year 2021.
The thing to note here is that year is not a query parameter and not the uri parameter. Hence it will filter all the patients and return the ones for whom year is 2021
What is the difference between a subflow and a sync flow?
- A . No difference
- B . Subflow has no error handling of its own and sync flow does
- C . Sync flow has no error handling of its own and subflow does
- D . Subflow is synchronous and sync flow is asynchronous
B
Explanation:
Correct answer is Subflow has no error handling implementation where as sync flow has. Subflow
A subflow processes messages synchronously (relative to the flow that triggered its execution) and always inherits both the processing strategy and exception strategy employed by the triggering flow. While a subflow is running, processing on the triggering flow pauses, then resumes only after the subflow completes its processing and hands the message back to the triggering flow.
Synchronous Flow
A synchronous flow, like a subflow, processes messages synchronously (relative to the flow that triggered its execution). While a synchronous flow is running, processing on the triggering flow pauses, then resumes only after the synchronous flow completes its processing and hands the message back to the triggering flow. However, unlike a subflow, this type of flow does not inherit processing or exception strategies from the triggering flow. This type of flow processes messages along a single thread, which is ideally suited to transactional processing

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
