Question 49

According to MuleSoft, what Action should an IT organization take regarding its technology assets in order to close the IT delivery.

Options:

A.

Make assets easily discoverable via a central repository

B.

Focus project delivery efforts on custom assets that meet the specific requirements of each individual line of business

C.

Create weekly meetings that all members of IT attend to present justification and request approval to use existing assets

Question 50

Refer to the exhibit.

This Mule application is deployed to multiple Cloudhub workers with persistent queue enabled. The retrievefile flow event source reads a CSV file from a remote SFTP server and then publishes each record in the CSV file to a VM queue. The processCustomerRecords flow’s VM Listner receives messages from the same VM queue and then processes each message separately.

How are messages routed to the cloudhub workers as messages are received by the VM Listener?

Options:

A.

Each message is routed to ONE of the Cloudhub workers in a DETERMINSTIC round robin fashion thereby EXACTLY BALANCING messages among the cloudhub workers

B.

Each messages routes to ONE of the available Clouhub workers in a NON- DETERMINSTIC non round-robin fashion thereby APPROXIMATELY BALANCING messages among the cloudhub workers

C.

Each message is routed to the SAME Cloudhub worker that retrieved the file, thereby BINDING ALL messages to ONLY that ONE Cloudhub worker

D.

Each message is duplicated to ALL of the Cloudhub workers, thereby SHARING EACH message with ALL the Cloudhub workers.

Question 51

The AnyAirline organization's passenger reservations center is designing an integration solution that combines invocations of three different System APIs (bookFlight, bookHotel, and bookCar) in a business transaction. Each System API makes calls to a single database.

The entire business transaction must be rolled back when at least one of the APIs fails.

What is the most idiomatic (used for its intended purpose) way to integrate these APIs in near real-time that provides the best balance of consistency, performance, and reliability?

Options:

A.

Implement eXtended Architecture (XA) transactions between the API implementations

Coordinate between the API implementations using a Saga pattern

Implement caching in each API implementation to improve performance

B.

Implement local transactions within each API implementation

Configure each API implementation to also participate in the same eXtended Architecture (XA) transaction

Implement caching in each API implementation to improve performance

C.

Implement local transactions in each API implementation

Coordinate between the API implementations using a Saga pattern

Apply various compensating actions depending on where a failure occurs

D.

Implement an eXtended Architecture (XA) transaction manager in a Mule application using a Saga pattern

Connect each API implementation with the Mule application using XA transactions

Apply various compensating actions depending on where a failure occurs

Question 52

A company is implementing a new Mule application that supports a set of critical functions driven by a rest API enabled, claims payment rules engine hosted on oracle ERP. As designed the mule application requires many data transformation operations as it performs its batch processing logic.

The company wants to leverage and reuse as many of its existing java-based capabilities (classes, objects, data model etc.) as possible

What approach should be considered when implementing required data mappings and transformations between Mule application and Oracle ERP in the new Mule application?

Options:

A.

Create a new metadata RAML classes in Mule from the appropriate Java objects and then perform transformations via Dataweave

B.

From the mule application, transform via theXSLT model

C.

Transform by calling any suitable Java class from Dataweave

D.

Invoke any of the appropriate Java methods directly, create metadata RAML classes and then perform required transformations via Dataweave
