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?

• A.Use a Scheduler to check for a response every minute
• B.Use an HTTP Connector to invoke the API and wait for a response
• C.Expose an HTTP callback API in Mule and register it with the external system
• D.Use an HTTP Connector inside Async scope to invoice the API and wait for a response

Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?

• A.A Parallel for Each scope with each HTTP request wrapped in a Try scope
• B.Scatter-Gather as central Saga orchestrator for all API request with compensating actions for failing routes
• C.VM queues as a reliability pattern with error handlers to roll back any requests
• D.A database as a transactional outbox and an Until Successful router to retry any requests

A Mule application defines as SSL/TLS keystore properly 'tis,keystore.keyPassword'' as secure.
How can this property be referenced to access its value within the application?

• A.#{secure::tiskeystore,keyPassowrd}
• B.p{secure::tiskeystore,keyPassowrd}
• C.${secure::tiskeystore,keyPassowrd}
• D.${secure::tiskeystore,keyPassowrd}

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?

• A.Monitor the Payment API directly sending real customer payment data
• B.Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
• C.Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
• D.Configure the application to send health data to an external system

A Flight Management System publishes gate change notification events whenever a flight's arrival gate changes. Other systems, including Baggage Handler System. Inflight Catering System and Passenger Notifications System, must each asynchronously receive the same gate change notification to process the event according.
Which configuration is required in Anypoint MQ to achieve this publish/subscribe model?

• A.Publish each client subscribe directly to the exchange.
  Have each client subscribe directly to the queue.
• B.Publish the gate change notification to an Anypoint MQ queue.
  Create different anypoint MQ exchange meant for each of the other subscribing systems Bind the queue with each of the exchanges
• C.Publish the gate change notification to an Anypoint MQ exchanhe.
  Create different Anypoint MQ queues meant for each of the other subscribing systems.
  Bind the exchange with each of the queues.
• D.Publish the gate change notification to an Anypoint MC queue
  Have each client subscribe directly to the queue
