An Order microservice and a Fulfillment microservice are being designed to communicate with their dients through message-based integration (and NOT through API invocations). The Order microservice publishes an Order message (a kind of command message) containing the details of an order to be fulfilled. The intention is that Order messages are only consumed by one Mute application, the Fulfillment microservice. The Fulfilment microservice consumes Order messages, fulfills the order described therein, and then publishes an OrderFulfilted message (a kind of event message). Each OrderFulfilted message can be consumed by any interested Mule application, and the Order microservice is one such Mute application. What is the most appropriate choice of message broker(s) and message destination(s) in this scenario?

Refer to the exhibit. A Mule 4 application has a parent flow that breaks up a JSON array payload into 200 separate items, then sends each item one at a time inside an Async scope to a VM queue. A second flow to process orders has a VM Listener on the same VM queue. The rest of this flow processes each received item by writing the item to a database. This Mule application is deployed to four CloudHub workers with persistent queues enabled. What message processing guarantees are provided by the VM queue and the CloudHub workers, and how are VM messages routed among the CloudHub workers for each invocation of the parent flow under normal operating conditions where all the CloudHub workers remain online?

What approach configures an API gateway to hide sensitive data exchanged between API consumers and API implementations, but can convert tokenized fields back to their original value for other API requests or responses, without having to recode the API implementations?

An organization is evaluating using the CloudHub shared Load Balancer (SLB) vs creating a CloudHub dedicated load balancer (DLB). They are evaluating how this choice affects the various types of certificates used by CloudHub deplpoyed Mule applications, including MuleSoft-provided, customer-provided, or Mule application-provided certificates. What type of restrictions exist on the types of certificates that can be exposed by the CloudHub Shared Load Balancer (SLB) to external web clients over the public internet?

An external REST client periodically sends an array of records in a single POST request to a Mule application API endpoint. The Mule application must validate each record of the request against a JSON schema before sending it to a downstream system in the same order that it was received in the array Record processing will take place inside a router or scope that calls a child flow. The child flow has its own error handling defined. Any validation or communication failures should not prevent further processing of the remaining records. To best address these requirements what is the most idiomatic(used for it intended purpose) router or scope to used in the parent flow, and what type of error handler should be used in the child flow?

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?

An organization uses a set of customer-hosted Mule runtimes that are managed using the Mulesoft-hosted control plane. What is a condition that can be alerted on from Anypoint Runtime Manager without any custom components or custom coding?

Question 181

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?

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

Upgrade vCore size from 0.1 vCore to 0,2 vCore

Implement HTTP caching policy for all GET endpoints for master lookup API

Add an additional Cloudhub worker to provide additional capacity

Question 182

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?

Remaining records will be processed by a new replacement worker

Remaining records be processed by second worker

Remaining records will be left and processed

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

Question 183

A company is designing a mule application to consume batch data from a partner's ftps server The data files have been compressed and then digitally signed using PGP.

What inputs are required for the application to securely consumed these files?

ATLS context Key Store requiring the private key and certificate for the company PGP public key of partner PGP private key for the company

ATLS context first store containing a public certificate for partner ftps server and the PGP public key of the partner TLS contact Key Store containing the FTP credentials

TLS context trust or containing a public certificate for the ftps server The FTP username and password The PGP public key of the partner

The PGP public key of the partner The PGP private key for the company The FTP username and password

Question 184

A mule application designed to fulfil two requirements

a) Processing files are synchronously from an FTPS server to a back-end database using VM intermediary queues for load balancing VM events

b) Processing a medium rate of records from a source to a target system using batch job scope

Considering the processing reliability requirements for FTPS files, how should VM queues be configured for processing files as well as for the batch job scope if the application is deployed to Cloudhub workers?

Use Cloud hub persistent queues for FTPS files processing There is no need to configure VM queues for the batch jobs scope as it uses by default the worker's disc for VM queueing

Use Cloud hub persistent VM queue for FTPS file processing There is no need to configure VM queues for the batch jobs scope as it uses by default the worker's JVM memory for VM queueing

Use Cloud hub persistent VM queues for FTPS file processing Disable VM queue for the batch job scope

Use VM connector persistent queues for FTPS file processing Disable VM queue for the batch job scope
