質問 1

A Mule application is built to support a local transaction for a series of operations on a single database. The mule application has a Scatter-Gather scope that participates in the local transaction.
What is the behavior of the Scatter-Gather when running within this local transaction?

（A）Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back

（B）Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations

（C）Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back

（D）Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations

（A）XA transactions and XA connected components

（B）JMS manual acknowledgements with a reliability pattern

（C）JMS transactions

（D）VM queues with reliability pattern

質問 3

One of the backend systems involved by the API implementation enforces rate limits on the number of request a particle client can make.
Both the back-end system and API implementation are deployed to several non-production environments including the staging environment and to a particular production environment. Rate limiting of the back-end system applies to all non-production environments.
The production environment however does not have any rate limiting.
What is the cost-effective approach to conduct performance test of the API implementation in the non-production staging environment?

（A）Including logic within the API implementation that bypasses in locations of the back-end system in the staging environment and invoke a Mocking service that replicates typical back-end system responses Then conduct performance test using this API implementation

（B）Create a Mocking service that replicates the back-end system's
production performance characteristics
Then configure the API implementation to use the mocking
service and conduct the performance test

（C）Conduct scaled-down performance tests in the staging environment against rate-limiting back-end system. Then upscale performance results to full production scale

（D）Use MUnit to simulate standard responses from the back-end system.
Then conduct performance test to identify other bottlenecks in the system

質問 4

Mule application is deployed to Customer Hosted Runtime. Asynchronous logging was implemented to improved throughput of the system. But it was observed over the period of time that few of the important exception log messages which were used to rollback transactions are not working as expected causing huge loss to the Organization. Organization wants to avoid these losses. Application also has constraints due to which they cant compromise on throughput much. What is the possible option in this case?

（A）Mixed configuration of asynchronous or synchronous loggers should be used to log exceptions via synchronous way

（B）Logging needs to be changed from asynchronous to synchronous

（C）External log appender needs to be used in this case

（D）Persistent memory storage should be used in such scenarios

質問 5

A system API EmployeeSAPI is used to fetch employee's data from an underlying SQL database.
The architect must design a caching strategy to query the database only when there is an update to the employees stable or else return a cached response in order to minimize the number of redundant transactions being handled by the database.
What must the architect do to achieve the caching objective?

（A）Use a Scheduler with a fixed frequency every hour triggering an invalidate cache flow Use an object store caching strategy and set expiration interval to 1-hour

（B）Use an on table rule on employees table call invalidate cache and said new employees data to cache Use an object store caching strategy and set expiration interval to 1-hour

（C）Use an On Table Row on employees table and call invalidate cache
Use an object store caching strategy and expiration interval to empty

（D）Use a Scheduler with a fixed frequency every hour triggering an invalidate cache flow Use an object store caching strategy and expiration interval to empty

質問 7

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?

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

（B）Transform by calling any suitable Java class from Dataweave

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

（D）From the mule application, transform via theXSLT model

質問 8

A marketing organization is designing a Mule application to process campaign data. The Mule application will periodically check for a file in a SFTP location and process the records in the file. The size of the file can vary from 10MB to 5GB. Due to the limited availabiltty of vCores, the Mule application is deployed to a single CloudHub worker configured with vCore size 0.2.
The application must transform and send different formats of this file to three different downstream SFTP locations.
What is the most idiomatic (used for its intended purpose) and performant way to configure the SFTP operations or event sources to process the large files to support these deployment requirements?

（A）Use a file-stored non-repeatable stream

（B）Use a file-stored repeatable stream

（C）Use an in-memory non-repeatable stream

（D）Use an in-memory repeatable stream

An organization is implementing a Quote of the Day API that caches today's quote. What scenario can use the CloudHub Object Store connector to persist the cache's state?

（A）When there is one deployment of the API implementation to CloudHub and another one to customer hosted mule runtime that must share the cache state.

（B）When there are two CloudHub deployments of the API implementation by two Anypoint Platform business groups to the same CloudHub region that must share the cache state.

（C）When there is one CloudHub deployment of the API implementation to three workers that must share the cache state.

（D）When there are three CloudHub deployments of the API implementation to three separate CloudHub regions that must share the cache state.

A finance giant is planning to migrate all its Mule applications to Runtime fabric (RTF). Currently all Mule applications are deployed cloud hub using automated CI/CD scripts.
As an integration architect, which of the below step would you suggest to ensure that the applications from cloudhub are migrated properly to Runtime Fabric (RTF) with an assumption that organization is keen on keeping the same deployment strategy.

（A）runtimeFabric deployment should be added to POM.xml file in all
the mule applications and CI/CD script should be modified as per the RTF configurations

（B）runtimeFabric dependency should be added as a mule plug-in to POM.xml file and CI/CD script should be modified as per the RTF configurations

（C）runtimeFabric profile should be added mule configuration files in the mule applications and CI/CD script should be modified as per the RTF configurations

（D）No changes need to be made to POM.xml file and CI/CD script should be modified as per the RTF configurations
