A mule application is required to periodically process large data set from a back-end database to Salesforce CRM using batch job scope configured properly process the higher rate of records.
The application is deployed to two cloudhub workers with no persistence queues enabled.
What is the consequence if the worker crashes during records processing?

（A）Remaining records will be processed by a new replacement worker

（B）Remaining records be processed by second worker

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

（D）Remaining records will be left and processed

質問 2

An application deployed to a runtime fabric environment with two cluster replicas is designed to periodically trigger of flow for processing a high-volume set of records from the source system and synchronize with the SaaS system using the Batch job scope After processing 1000 records in a periodic synchronization of 1 lakh records, the replicas in which batch job instance was started went down due to unexpected failure in the runtime fabric environment What is the consequence of losing the replicas that run the Batch job instance?

（A）The remaining 99000 records will be lost and left and processed

（B）The second replicas will take over processing the remaining
99000 records

（C）A new placement replica will be available and will take or processing the remaining 99,000 records

（D）A new replacement replica will be available and will be process all 1,00,000 records from scratch leading to duplicate record processing

As a part of design , Mule application is required call the Google Maps API to perform a distance computation. The application is deployed to cloudhub.
At the minimum what should be configured in the TLS context of the HTTP request configuration to meet these requirements?

（A）Download the Google public certificate from a browser, generate a JKS file from it and add it in Truststore as part of the TLS context

（B）The configuration is built-in and nothing extra is required for the TLS context

（C）Download the Google public certificate from a browser, generate JKS file from it and add it in key store as a part of TLS context

（D）Request a private key from Google and create a PKCS12 file with it and add it in keyStore as a part of TLS context

質問 4

An organization is migrating all its Mule applications to Runtime Fabric (RTF). None of the Mule applications use Mule domain projects.
Currently, all the Mule applications have been manually deployed to a server group among several customer hosted Mule runtimes.
Port conflicts between these Mule application deployments are currently managed by the DevOps team who carefully manage Mule application properties files.
When the Mule applications are migrated from the current customer-hosted server group to Runtime Fabric (RTF), fo the Mule applications need to be rewritten and what DevOps port configuration responsibilities change or stay the same?

（A）Yes, the Mule applications Must be rewritten
DevOps No Longer needs to manage port conflicts between the Mule applications

（B）NO, The Mule applications do NOT need to be rewritten
DevOps MUST STILL manage port conflicts

（C）Yes, the Mule applications Must be rewritten
DevOps Must Still Manage port conflicts.

（D）NO, the Mule applications do NO need to be rewritten
DevOps NO LONGER needs to manage port conflicts between the Mule applications.

質問 5

When the mule application using VM is deployed to a customer-hosted cluster or multiple cloudhub workers, how are messages consumed by the Mule engine?

（A）by starting an XA transaction for each new message

（B）in a deterministic way

（C）in non-deterministic way

（D）the primary only in order to avoid duplicate processing

質問 6

What is a key difference between synchronous and asynchronous logging from Mule applications?

（A）Asynchronous logging produces more reliable audit trails with more accurate timestamps

（B）Synchronous logging within an ongoing transaction writes log messages in the same thread that processes the current Mule event

（C）Synchronous logging writes log messages in a single logging thread but does not block the Mule event being processed by the next event processor

（D）Asynchronous logging can improve Mule event processing throughput while also reducing the processing time for each Mule event

質問 7

An organization is designing a Mule application to periodically poll an SFTP location for new files containing sales order records and then process those sales orders. Each sales order must be processed exactly once.
To support this requirement, the Mule application must identify and filter duplicate sales orders on the basis of a unique ID contained in each sales order record and then only send the new sales orders to the downstream system.
What is the most idiomatic (used for its intended purpose) Anypoint connector, validator, or scope that can be configured in the Mule application to filter duplicate sales orders on the basis of the unique ID field contained in each sales order record?

（A）Configure a Cache scope to filter and store each record from the received file by the order ID

（B）Configure a watermark In an On New or Updated File event source to filter unique records by the order ID

（C）Configure a Database connector to filter and store each record by the order ID

（D）Configure an Idempotent Message Validator component to filter each record by the order ID

質問 8

A banking company is developing a new set of APIs for its online business. One of the critical API's is a master lookup API which is a system API. This master lookup API uses persistent object store. This API will be used by all other APIs to provide master lookup data.

Master lookup API is deployed on two cloudhub workers of 0.1 vCore each because there is a lot of master data to be cached. Master lookup data is stored as a key value pair. The cache gets refreshed if they key is not found in the cache.
Doing performance testing it was observed that the Master lookup API has a higher response time due to database queries execution to fetch the master lookup data.
Due to this performance issue, go-live of the online business is on hold which could cause potential financial loss to Bank.
As an integration architect, which of the below option you would suggest to resolve performance issue?

（A）Add an additional Cloudhub worker to provide additional capacity

（B）Upgrade vCore size from 0.1 vCore to 0,2 vCore

（C）Implement HTTP caching policy for all GET endpoints for master lookup API

（D）Implement HTTP caching policy for all GET endpoints for the master lookup API and implement locking to synchronize access to object store

質問 9

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 10

An organization is designing multiple new applications to run on CloudHub in a single Anypoint VPC and that must share data using a common persistent Anypoint object store V2 (OSv2).
Which design gives these mule applications access to the same object store instance?

（A）An Anypoint MQ connector configured to directly access the persistent object store

（B）AVM connector configured to directly access the persistence queue of the persistent object store

（C）The object store V2 rest API configured to access the persistent object store

（D）Object store V2 can be shared across cloudhub applications with the configured osv2 connector
