Question 10

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?

Options:

A.

An 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

B.

One 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

C.

One 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

D.

A 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

Question 11

Options:

A.

Remaining records will be processed by a new replacement worker

B.

Remaining records be processed by second worker

C.

Remaining records will be left and processed

D.

All the records will be processed from scratch by the second worker leading to duplicate processing

Question 13

An organization has implemented a continuous integration (CI) lifecycle that promotes Mule applications through code, build, and test stages. To standardize the organization's CI journey, a new dependency control approach is being designed to store artifacts that include information such as dependencies, versioning, and build promotions.

To implement these process improvements, the organization will now require developers to maintain all dependencies related to Mule application code in a shared location.

Question 15

An API implementation is being developed to expose data from a production database via HTTP requests. The API implementation executes a database SELECT statement that is dynamically created based upon data received from each incoming HTTP request. The developers are planning to use various types of testing to make sure the Mule application works as expected, can handle specific workloads, and behaves correctly from an API consumer perspective.

Question 16

A company 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 HTTP5 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 the rejections from the back-end system will need to be processed manually (outside the banking system).

The mule application will be deployed to a customer hosted runtime and will be 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.
