Question 43

A company is planning to migrate its deployment environment from on-premises cluster to a Runtime Fabric (RTF) cluster. It also has a requirement to enable Mule applications deployed to a Mule runtime instance to store and share data across application replicas and restarts.
How can these requirements be met?

A. Anypoint object store V2 to share data between replicas in the RTF cluster

B. Install the object store pod on one of the cluster nodes

C. Configure Persistence Gateway in any of the servers using Mule Object Store

D. Configure Persistent Gateway at the RTF

Correct Answer:A

Question 44

A Mule application contains a Batch Job scope with several Batch Step scopes. The Batch Job scope is configured with a batch block size of 25.
A payload with 4,000 records is received by the Batch Job scope.
When there are no errors, how does the Batch Job scope process records within and between the Batch Step scopes?

A. The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records Each Batch Step scope is invoked with one record in the payload of the received Mule eventFor each Batch Step scope, all 25 records within a block are processed in parallelAll the records in a block must be completed before the block of 25 records is available to the next Batch Step scope

B. The Batch Job scope processes each record block sequentially, one at a time Each Batch Step scope is invoked with one record in the payload of the received Mule eventFor each Batch Step scope, all 25 records within a block are processed sequentially, one at a timeAll 4000 records must be completed before the blocks of records are available to the next Batch Step scope

C. The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records Each Batch Step scope is invoked with one record in the payload of the received Mule eventFor each Batch Step scope, all 25 records within a block are processed sequentially, one record at a timeAll the records in a block must be completed before the block of 25 records is available tothe next Batch Step scope

D. The Batch Job scope processes multiple record blocks in parallelEach Batch Step scope is invoked with a batch of 25 records in the payload of the received Mule eventFor each Batch Step scope, all 4000 records are processed in parallelIndividual records can jump ahead to the next Batch Step scope before the rest of the records finish processing in the current Batch Step scope

Correct Answer:A

Question 45

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?

A. Implement eXtended Architecture (XA) transactions between the API implementations Coordinate between the API implementations using a Saga patternImplement caching in each API implementation to improve performance

B. Implement local transactions within each API implementationConfigure each API implementation to also participate in the same eXtended Architecture (XA) transactionImplement caching in each API implementation to improve performance

C. Implement local transactions in each API implementation Coordinate between the API implementations using a Saga patternApply various compensating actions depending on where a failure occurs

D. Implement an eXtended Architecture (XA) transaction manager in a Mule application using a Saga patternConnect each API implementation with the Mule application using XA transactionsApply various compensating actions depending on where a failure occurs

Correct Answer:C

Question 46

The implementation of a Process API must change. What is a valid approach that minimizes the impact of this change on API clients?

A. Implement required changes to the Process API implementation so that whenever possible, the Process API's RAML definition remains unchanged

B. Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

C. Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version

D. Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation

Correct Answer:A

Question 47

A Mule application currently writes to two separate SQL Server database instances across the internet using a single XA transaction. It is 58. proposed to split this one transaction into two separate non-XA transactions with no other changes to the Mule application.
What non-functional requirement can be expected to be negatively affected when implementing this change?

A. Throughput

B. Consistency

C. Response time

D. Availability

Correct Answer:B

Question 48

Anypoint Exchange is required to maintain the source code of some of the assets committed to it, such as Connectors, Templates, and API specifications.
What is the best way to use an organization's source-code management (SCM) system in this context?

A. Organizations should continue to use an SCM system of their choice, in addition to keeping source code for these asset types in Anypoint Exchange, thereby enabling parallel development, branching, and merging

B. Organizations need to use Anypoint Exchange as the main SCM system to centralize versioning and avoid code duplication

C. Organizations can continue to use an SCM system of their choice for branching and merging, as long as they follow the branching and merging strategy enforced by Anypoint Exchange

D. Organizations need to point Anypoint Exchange to their SCM system so Anypoint Exchange can pull source code when requested by developers and provide it to Anypoint Studio
