QUESTION 54
Refer to the exhibits.

This main mule application calls a separate flow called as ShippingAddress which returns the address corresponding to the name of the user sent to it as input. Output of this ShippingAddress is stored in a target variable named address.
Next set of requirement is to have a setPayload transformer which will set below two values
1) orderkey which needs to set to be equal to the order element received in the original request payload.
2) addressKey which needs to be set to be equal to the address received in response of ShippingAddress flow What is the straightforward way to properly configure the Set Payload transformer with the required data?

A mule application is being developed which will process POST requests coming from clients containing the name and order information. Sample request is as below

1. 1. {
2. 2. orderkey: “payload.order”,
3. 3. addresskey: “vars.address”
4. 4. }

1. 1. {
2. 2. orderkey: “attributes.shippingaddress.order”,
3. 3. addresskey: “payload”
4. }

1. 1. {
2. 2. orderkey: “payload.order”,
3. 3. addresskey: “address”
4. }

1. 1. {
2. 2. orderkey: “attributes.order”,
3. 3. addresskey: “vars.address”
4. }

Correct answer is as below. In this case address will be stored in a variable. Hence payload will not be overwritten and will contain order details
{
orderkey: “payload.order”,
addresskey: “vars.address”
}

QUESTION 55
Refer to the exhibits.

The Validation component in the private flow throws an error. What response message is returned to a client request to the main flow’s HTTP Listener?

Error – private flow

Error – main flow

Success – main flow

Validation Error

QUESTION 56
Refer to the exhibit.

What is the response to a web client request to http://localhost:8081?

After

before

Validation Error

null

QUESTION 57
Refer to the exhibit.

What is the output payload in the On Complete phase

summary statistics with NO record data

The records processed by the last batch step: [StepTwol, StepTwo2, StepTwo3]

The original payload: [1,2,31

This is a trcik question. On complete phase pyalod consists of summary of records processed which gives insight on which records failed or passed. Hence option 4 is correct answer MuleSoft Documentation Reference : https://docs.mulesoft.com/mule-runtime/4.3/batch-processing-concept#on-complete

MuleSoft Doc Ref : https://docs.mulesoft.com/runtime-manager/cloudhub-architecture#cloudhub-workers 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:

—
toUpper(“hello”)

QUESTION 67
Refer to the exhibit.

What is the output payload in the On Complete phase

summary statistics with NO record data

The records processed by the last batch step: [StepTwol, StepTwo2, StepTwo3]

The records processed by all batch steps: [StepTwostepOnel, stepTwostepOne2, StepTwoStepOne3]

The original payload: [1,2,31

QUESTION 68
Refer to the exhibit.

What is the correct DataWeave expression for the Set Payload transformer to call the createCustomerObject flow with values for the first and last names of a new customer?

lookupC createCustomerObJect( “Alice”, “Green- ) )

createCustomerObject( { first: “Alice”, last: “Green” > )

lookupf “createCustomerObject”, { first: “Alice”, last: “Green” > )

createCustomerObject( “Alice”, “Green”)

QUESTION 69
Refer to the exhibits.

The Validation component in the Try scope throws an error.
What response message is returned to a client request to the main flow’s HTTP Listener?
The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow’s HTTP Listener?

Success – main flow

Error – main flow

Error – Try scope

Validation Error

Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scope which sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success – main flow.
Hence correct answer is Success – main flow
1) HTTP listener received request
2) The Flow Reference calls the child flow
3) The Is Number validator creates an Error Object because the payload isn’t an integer. Child Flow execution stops
#[error.description] = “payload is not a valid INTEGER value”
#[error.errorType] = VALIDATION:INVALID_NUMBER
4) The On Error Continue handles the errorThe payload is set to “Error – Sub Flow”
5) “Error – Sub Flow” is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to “Success – Finished Main Flow”
6) “Success – Main Flow” is returned to the requestor in the body of the HTTP request. HTTP Status Code:
200
As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.

QUESTION 70
Refer to the exhibits.

The two Mule configuration files belong to the same Mule project. Each HTTP Listener is configured with the same host string and the port number, path, and operation values are shown in the display names.
What is the minimum number of global elements that must be defined to support all these HTTP Listeners?

In this case three configurations will be required each for port 8000, 6000 and 7000.
There would be three global elements defined for HTTP connections.
Each HTTP connection will have host and port. One example shown below with host as localhost and port
6000
Graphical user interface, application Description automatically generated

To use an HTTP listener, you need to declare a configuration with a corresponding connection. This declaration establishes the HTTP server that will listen to requests.
Additionally, you can configure a base path that applies to all listeners using the configuration.
* <http:listener-config name=”HTTP_Listener_config” basePath=”api/v1″>
* <http:listener-connection host=”0.0.0.0″ port=”8081″ />
* </http:listener-config>

Refer to the exhibits. A database Address table contains a ZIPCODE column and an increasing ID column.
The Address table currently contains tour (4) records. The On Table Row Database listener is configured with its watermark set to the Address table’s ZIPCODE column and then the Mule application is run in Anypoint Studio tor the first time, and the On Table Row Database listener polls the Address table.
Anew row is added to the database with 1D=5 and ZIPCODE-90006, and then the On Table Row Database listener polls the database again.
