NO.19 A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process.
Which implementation should be used to get response data from the external API after it completes processing?

Use an HTTP Connector to invoke the API and wait for a response

Use a Scheduler to check for a response every minute

Use an HTTP Connector inside Async scope to invoice the API and wait for a response

Expose an HTTP callback API in Mule and register it with the external system

NO.20 An order processing system is composed of multiple Mule application responsible for warehouse, sales and shipping. Each application communication using Anypoint MQ. Each message must be correlated against the original order ID for observability and tracing.
How should a developer propagate the order ID as the correlation ID across each message?

Use the underlying HTTP request of Anypoint MQ to set the ‘X-CORRELATION_ID’ header to the order ID

Set a custom Anypoint MQ user property to propagate the order ID and set the correlation ID in the receiving applications.

Use the default correlation ID, Anypoint MQ will sutomatically propagate it.

Wrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID

NO.21 A Mule application uses API autodiscovery to access and enforce policies for a RESTful implementation.

Northing because flowRef is an optional attribute which can be passed runtime

The name of the flow that has APlkit Console to receive all incoming RESTful operation requests.

Any of the APIkit generate implement flows

The name of the flow that has HTTP listener to receive all incoming RESTful operation requests

NO.22 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?

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

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

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

None, the flow already exhibits idempotent behavior

NO.23 Which pattern can a web API use to notify its client of state changes as soon as they occur?

HTTP Webhock

Shared database trigger

Schedule Event Publisher

ETL data load

NO.24 Refer to the exhibit.
What is the result if ”Insecure” selected as part of the HTTP Listener configuration?

The HTTP Listener will trust any certificate presented by the HTTP client

The HTTP Lister will accept any unauthenticated request

The HTTP listener will only accept HTTP requests

Mutual TLS authentication will be enabled between this HTTP Listener and an HTTP client

NO.25 Refer to the exhibit.
A Mute Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.
What is the result of the flow if processing between os’store and os:retrieve takes 10 seconds?

nullPayload

originalPayload

OS:KEY_NOT_FOUND

testPayload

NO.26 A Mule application deployed to a standardalone Mule runtime uses VM queues to publish messages to be consumed asynchronously by another flow.
In the case of a system failure, what will happen to in-flight messages in the VM queues that have been consumed?

For nay type of queue, the message will be processed after the system comes online

For persistent queues, the message will be processed after the system comes online

For transient queues, the message will be processed after the system comes online

For any type of queue, the message will be lost

NO.27 Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?

A database as a transactional outbox and an Until Successful router to retry any requests

A Parallel for Each scope with each HTTP request wrapped in a Try scope

Scatter-Gather as central Saga orchestrator for all API request with compensating actions for failing routes

VM queues as a reliability pattern with error handlers to roll back any requests

NO.28 An API has been built to enable scheduling email provider. The front-end system does very little data entry validation, and problems have started to appear in the email that go to patients. A validate-customer” flow is added validate the data.
What is he expected behavior of the ‘validate-customer” flow?

If only the email address Is invalid a VALIDATION.INVALID_EMAIL error is raised

If the email address is invalid, processing continues to see if the appointment data and customer name are also invalid

If the appointment date and customer name are invalid, a
SCHEDULE:INVALID_APPOINTMENT_DATE error is raised

If all of the values are invalid the last validation error is
raised:SCHEDULE:INVALID_CUSTOMER_NAME

NO.29 Which statement is true about using mutual TLS to secure an application?

Mutual TLS requires a hardware security module to be used

Mutual TLS authenticates the identity of the server before the identity of the client

Mutual TLS ensures only authorized end users are allowed to access an endpoint

Mutual TLS increases the encryption strength versus server-side TLS alone

NO.30 Refer to the exhibit.

The flow name is ”implementation” with code for the MUnit test case.
When the MUnit test case is executed, what is the expected result?

The test case fails with an assertion error

The test throws an error and does not start

The test case fails with an unexpected error type

The test case passes

NO.31 A healthcare portal needs to validate the token that it sends to a Mule API. The developer plans to implement a custom policy using the HTTP Policy Transform Extension to match the token received in the header from the heathcare portal.
Which files does the developer need to create in order to package the custom policy?

Deployable ZIP file, YAML configuration file

JSON properties file, YAML configuration file

JSON properties file, XML template file

XML template file, YAML configuration file

NO.32 When implementing a synchronous API where the event source is an HTTP Listener, a developer needs to return the same correlation ID back to the caller in the HTTP response header.
How can this be achieved?

Enable the auto-generate CorrelationID option when scaffolding the flow

Enable the CorrelationID checkbox in the HTTP Listener configuration

Configure a custom correlation policy

NO action is needed as the correlation ID is returned to the caller in the response header by default

NO.33 A Mule application contain two policies Policy A and Policy A has order1, and Policy B has order 2. Policy A Policy B, and a flow are defined by he configuration below.

When a HTTP request arrives at the Mule application’s endpoint, what will be the execution order?

A1, B1, F1, B2, A2

B1, A1, F1, A2, B2

F1, A1, B1, B2, A2

F1, B1, A1, A2, B2
