Answer : C

Question 2

An organization is designing an integration Mule application to process orders by submitting them to a back-end system for offline processing. Each order will be received by the Mule application through an HTTPS POST and must be acknowledged immediately. Once acknowledged, the order will be submitted to a back-end system. Orders that cannot be successfully submitted due to rejections from the back-end system will need to be processed manually (outside the back-end system).

The Mule application will be deployed to a customer-hosted runtime and is able to use an existing ActiveMQ broker if needed. The ActiveMQ broker is located inside the organization's firewall. The back-end system has a track record of unreliability due to both minor network connectivity issues and longer outages.

What idiomatic (used for their intended purposes) combination of Mule application components and ActiveMQ queues are required to ensure automatic submission of orders to the back-end system while supporting but minimizing manual order processing?

AAn Until Successful scope to call the back-end system
One or more ActiveMQ long-retry queues
One or more ActiveMQ dead-letter queues for manual processing

BOne or more On Error scopes to assist calling the back-end system
An Until Successful scope containing VM components for long retries
A persistent dead-letter VM queue configured in CloudHub

COne or more On Error scopes to assist calling the back-end system
One or more ActiveMQ long-retry queues
A persistent dead-letter object store configured in the CloudHub Object Store service

DA Batch Job scope to call the back-end system
An Until Successful scope containing Object Store components for long retries
A dead-letter object store configured in the Mule application

Answer : A

Question 3

An XA transaction Is being configured that involves a JMS connector listening for Incoming JMS messages. What is the meaning of the timeout attribute of the XA transaction, and what happens after the timeout expires?

AThe time that is allowed to pass between committing the transaction and the completion of the Mule flow After the timeout, flow processing triggers an error

BThe time that Is allowed to pass between receiving JMS messages on the same JMS connection After the timeout, a new JMS connection Is established

CThe time that Is allowed to pass without the transaction being ended explicitly After the timeout, the transaction Is forcefully rolled-back

DThe time that Is allowed to pass for state JMS consumer threads to be destroyed After the timeout, a new JMS consumer thread is created

Answer : C

* Setting a transaction timeout for the Bitronix transaction manager

Set the transaction timeout either

-- In wrapper.conf

-- In CloudHub in the Properties tab of the Mule application deployment

The default is 60 secs. It is defined as

mule.bitronix.transactiontimeout = 120

* This property defines the timeout for each transaction created for this manager.

If the transaction has not terminated before the timeout expires it will be automatically rolled back.

---------------------------------------------------------------------------------------------------------------------

Additional Info around Transaction Management:

Bitronix is available as the XA transaction manager for Mule applications

To use Bitronix, declare it as a global configuration element in the Mule application

<bti:transaction-manager />

Each Mule runtime can have only one instance of a Bitronix transaction manager, which is shared by all Mule applications

For customer-hosted deployments, define the XA transaction manager in a Mule domain

-- Then share this global element among all Mule applications in the Mule runtime

Question 4

Mule application A receives a request Anypoint MQ message REQU with a payload containing a variable-length list of request objects. Application A uses the For Each scope to split the list into individual objects and sends each object as a message to an Anypoint MQ queue.

Service S listens on that queue, processes each message independently of all other messages, and sends a response message to a response queue.

Application A listens on that response queue and must in turn create and publish a response Anypoint MQ message RESP with a payload containing the list of responses sent by service S in the same order as the request objects originally sent in REQU.

Assume successful response messages are returned by service S for all request messages.

What is required so that application A can ensure that the length and order of the list of objects in RESP and REQU match, while at the same time maximizing message throughput?

AUse a Scatter-Gather within the For Each scope to ensure response message order Configure the Scatter-Gather with a persistent object store

BPerform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU

CUse an Async scope within the For Each scope and collect response messages in a second For Each scope in the order In which they arrive, then send RESP using this list of responses

DKeep track of the list length and all object indices in REQU, both in the For Each scope and in all communication involving service Use persistent storage when creating RESP

Answer : D

Correct answer is Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU : Using Anypoint MQ, you can create two types of queues: Standard queue These queues don't guarantee a specific message order. Standard queues are the best fit for applications in which messages must be delivered quickly. FIFO (first in, first out) queue These queues ensure that your messages arrive in order. FIFO queues are the best fit for applications requiring strict message ordering and exactly-once delivery, but in which message delivery speed is of less importance Use of FIFO queue is no where in the option and also it decreased throughput. Similarly persistent object store is not the preferred solution approach when you maximizing message throughput. This rules out one of the options. Scatter Gather does not support ObjectStore. This rules out one of the options. Standard Anypoint MQ queues don't guarantee a specific message order hence using another for each block to collect response wont work as requirement here is to ensure the order. Hence considering all the above factors the feasible approach is Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU

Question 5

As part of a growth strategy, a supplier signs a trading agreement with a large customer. The customer sends purchase orders to the supplier according to the ANSI X12 EDI standard, and the supplier creates the orders in its ERP system using the information in the EDI document.

The agreement also requires that the supplier provide a new RESTful API to process request from the customer for current product inventory level from the supplier' s ERP system.

Which two fundamental integration use cases does the supplier need to deliver to provide an end-to-end solution for this business scenario? (Choose two.)

ASynchronized data transfer

BSharing data with external partners

CUser interface integration

DStreaming data ingestion

EData mashups

Answer : A, B

Question 6

An organization is designing Mule application which connects to a legacy backend. It has been reported that backend services are not highly available and experience downtime quite often. As an integration architect which of the below approach you would propose to achieve high reliability goals?

AAlerts can be configured in Mule runtime so that backend team can be communicated when services are down

BUntil Successful scope can be implemented while calling backend API's

COn Error Continue scope to be used to call in case of error again

DCreate a batch job with all requests being sent to backend using that job as per the availability of backend API's

Answer : B

Correct answer is Untill Successful scope can be implemented while calling backend API's The Until Successful scope repeatedly triggers the scope's components (including flow references) until they all succeed or until a maximum number of retries is exceeded The scope provides option to control the max number of retries and the interval between retries The scope can execute any sequence of processors that may fail for whatever reason and may succeed upon retry

Question 7

A Mule application uses APIkit for SOAP to implement a SOAP web service. The Mule application has been deployed to a CloudHub worker in a testing environment.

The integration testing team wants to use a SOAP client to perform Integration testing. To carry out the integration tests, the integration team must obtain the interface definition for the SOAP web service.

What is the most idiomatic (used for its intended purpose) way for the integration testing team to obtain the interface definition for the deployed SOAP web service in order to perform integration testing with the SOAP client?

ARetrieve the OpenAPI Specification file(s) from API Manager

BRetrieve the WSDL file(s) from the deployed Mule application

CRetrieve the RAML file(s) from the deployed Mule application

DRetrieve the XML file(s) from Runtime Manager

Answer : D
