Question No. 1

A Mule application includes a subflow containing a Scatter.Gather scope. Within each log of the Scatter.Gatter. an HTTP connector calls a PUT endpoint to modify records in different upstream system. The subflow is called inside an Unit successful scope to retry if a transitory exception is raised.

A technical spike is being performed to increase reliability of the Mule application.

Which steps should be performed within the Mule flow above the ensure idempontent behavior?

AChange the PUT requests inside the Scatter-Gather to POST requests

BEnsure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails

CRemove the Put requests from the Scatter-Getter and perform them sequentially

DNone, the flow already exhibits idempotent behavior

Show Answer

Correct Answer: B

To ensure idempotent behavior within a Mule flow that contains a subflow with a Scatter-Gather scope, the developer should ensure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails. Idempotency means that multiple identical requests have the same effect as a single request. Therefore, if one of the HTTP requests inside the Scatter-Gather fails, the error-handling flow should undo any changes made by other successful requests to ensure consistency and avoid partial updates.

Question No. 2

Refer to the exhibit.

What required changes can be made to give a partial successful response in case the United Airlines API returns with a timeout?

AAdd a Scatter-gather component inside a Try scope.
Set the payload to a default value 'Error' inside the error handler using the On Error Propagate scope.

BAdd Flow Reference components inside a Try scope.
Set the payload to a default value'' insider the error handler using the ON Error Continue scope

CAdd Flow Reference components inside a Try scope
Set the payload to a default value '' inside the error handler using the On Error Propagate scope

DAdd a Scatter-Gather component inside a Try scope.
Set the payload to a default value 'Error'' inside the error handler using the On Error Continue scope.

Show Answer

Correct Answer: D

To give a partial successful response in case the United Airlines API returns with a timeout, the developer should add a Scatter-Gather component inside a Try scope, and set the payload to a default value 'Error' inside the error handler using the On Error Continue scope. A Scatter-Gather component allows sending multiple requests concurrently and aggregating the responses into an array. A Try scope allows handling errors that occur within it using an error handler. An On Error Continue scope allows continuing the flow execution after handling an error. Therefore, by using these components, the developer can send requests to both APIs in parallel, handle any timeout errors from United Airlines API, and return a partial response with a default value for that API.

Question No. 3

The HTTP Request operation raises an HTTP CONNECTIVITY error.

Which HTTP status code and body are returned to the web client?

AHTTP Status Code:200.
Body 'Error in processing your request

BHTTP Status Code:500.
Body 'The HTTP CONNECTIVITY Error description

CHTTP Status Code:500.
Body 'Error in processing your request

DHTTP Status Code:500.
Body 'Error in processing your request

Show Answer

Correct Answer: C

When the HTTP Request operation raises an HTTP CONNECTIVITY error, it triggers an on-error-continue handler that sets a payload with 'Error in processing your request'. Since no status code is explicitly set in this handler, it defaults to 500 (INTERNAL SERVER ERROR). Therefore, the web client receives an HTTP response with status code 500 and body 'Error in processing your request'.

Question No. 4

What is the MuleSoft recommended method to encrypt sensitive property data?

AThe encryption key and sensitive data should be different for each environment

BThe encryption key should be identical for all environments

CThe encryption key should be identical for all environments and the sensitive data should be different for each environment

DThe encryption key should be different for each environment and the sensitive data should be the same for all environments

Show Answer

Correct Answer: A

The MuleSoft recommended method to encrypt sensitive property data is to use the Secure Properties Tool that comes with Anypoint Studio. This tool allows encrypting properties files with a secret key and then decrypting them at runtime using the same key. The encryption key and sensitive data should be different for each environment to ensure security and avoid accidental exposure of sensitive data. Reference: https://docs.mulesoft.com/mule-runtime/4.3/secure-configuration-properties

Question No. 5

A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production.

Which approach should be used to test that the payment API is working in production?

ACreate a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API

BConfigure the application to send health data to an external system

CCreate a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself

DMonitor the Payment API directly sending real customer payment data

Show Answer

Correct Answer: A

To test that the payment API is working in production, the developer should create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API. This way, the developer can isolate the health check endpoint from the API traffic and avoid affecting the performance or availability of the API. The health check endpoint should return a simple response that indicates the status of the API, such as OK or ERROR.
