6. An integration Mule application is deployed to a customer-hosted multi-node Mule 4 runtime duster. The Mule application uses a Listener operation of a JMS connector to receive incoming messages from a JMS queue.

How are the messages consumed by the Mule application?

Depending on the JMS provider's configuration, either all messages are consumed by ONLY the primary cluster node or else ALL messages are consumed by ALL cluster nodes

Regardless of the Listener operation configuration, all messages are consumed by ALL cluster nodes

Depending on the Listener operation configuration, either all messages are consumed by ONLY the primary cluster node or else EACH message is consumed by ANY ONE cluster node

Regardless of the Listener operation configuration, all messages are consumed by ONLY the primary cluster node

7. What Anypoint Connectors support transactions?

Database, JMS, VM

Database, 3MS, HTTP

Database, JMS, VM, SFTP

Database, VM, File

8. 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?

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 event For each Batch Step scope, all 25 records within a block are processed in parallel All the records in a block must be completed before the block of 25 records is available to the next Batch Step scope

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 event For each Batch Step scope, all 25 records within a block are processed sequentially, one at a time All 4000 records must be completed before the blocks of records are available to the next Batch Step scope

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 event For each Batch Step scope, all 25 records within a block are processed sequentially, one record at a time All the records in a block must be completed before the block of 25 records is available to the next Batch Step scope

The Batch Job scope processes multiple record blocks in parallel Each Batch Step scope is invoked with a batch of 25 records in the payload of the received Mule event For each Batch Step scope, all 4000 records are processed in parallel Individual records can jump ahead to the next Batch Step scope before the rest of the records finish processing in the current Batch Step scope

9. 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?

Logging needs to be changed from asynchronous to synchronous

External log appender needs to be used in this case

Persistent memory storage should be used in such scenarios

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

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

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

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

Asynchronous logging produces more reliable audit trails with more accurate timestamps

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

11. A Mule application uses the Database connector.

What condition can the Mule application automatically adjust to or recover from without needing to restart or redeploy the Mule application?

One of the stored procedures being called by the Mule application has been renamed

The database server was unavailable for four hours due to a major outage but is now fully operational again

The credentials for accessing the database have been updated and the previous credentials are no longer valid

The database server has been updated and hence the database driver library/JAR needs a minor version upgrade

12. An organization has defined a common object model in Java to mediate the communication between different Mule applications in a consistent way. A Mule application is being built to use this common object model to process responses from a SOAP API and a REST API and then write the processed results to an order management system.

The developers want Anypoint Studio to utilize these common objects to assist in creating mappings for various transformation steps in the Mule application.

What is the most idiomatic (used for its intended purpose) and performant way to utilize these common objects to map between the inbound and outbound systems in the Mule application?

Use JAXB (XML) and Jackson (JSON) data bindings

Use the WSS module

Use the Java module

Use the Transform Message component

13. An organization currently uses a multi-node Mule runtime deployment model within their datacenter, so each Mule runtime hosts several Mule applications. The organization is planning to transition to a deployment model based on Docker containers in a Kubernetes cluster. The organization has already created a standard Docker image containing a Mule runtime and all required dependencies (including a JVM), but excluding the Mule application itself.

What is an expected outcome of this transition to container-based Mule application deployments?

Required redesign of Mule applications to follow microservice architecture principles

Required migration to the Docker and Kubernetes-based Anypoint Platform - Private Cloud Edition

Required change to the URL endpoints used by clients to send requests to the Mule applications

Guaranteed consistency of execution environments across all deployments of a Mule application

14. What limits if a particular Anypoint Platform user can discover an asset in Anypoint Exchange?

Design Center and RAML were both used to create the asset

The existence of a public Anypoint Exchange portal to which the asset has been published

The type of the asset in Anypoint Exchange

The business groups to which the user belongs

15. 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 deployed Mule applications, including MuleSoft-provided, customer-provided, or Mule application-provided certificates.

What type of restrictions exist on the types of certificates for the service that can be exposed by the CloudHub Shared Load Balancer (SLB) to external web clients over the public internet?

Underlying Mule applications need to implement own certificates

Only MuleSoft provided certificates can be used for server side certificate

Only self signed certificates can be used

All certificates which can be used in shared load balancer need to get approved by raising support ticket

16. What is true about the network connections when a Mule application uses a JMS connector to interact with a JMS provider (message broker)?

To complete sending a JMS message, the JMS connector must establish a network connection with the JMS message recipient

To receive messages into the Mule application, the JMS provider initiates a network connection to the JMS connector and pushes messages along this connection

The JMS connector supports both sending and receiving of JMS messages over the protocol determined by the JMS provider

The AMQP protocol can be used by the JMS connector to portably establish connections to various types of JMS providers

17. A Mule application is being designed to do the following:

Step 1: Read a SalesOrder message from a JMS queue, where each SalesOrder consists of a header and a list of SalesOrderLineltems.

Step 2: Insert the SalesOrder header and each SalesOrderLineltem into different tables in an RDBMS.

Step 3: Insert the SalesOrder header and the sum of the prices of all its SalesOrderLineltems into a table In a different RDBMS.

No SalesOrder message can be lost and the consistency of all SalesOrder-related information in both RDBMSs must be ensured at all times.

What design choice (including choice of transactions) and order of steps addresses these requirements?

1) Read the JMS message (NOT in an XA transaction) 2) Perform BOTH DB inserts in ONE DB transaction 3) Acknowledge the JMS message

1) Read the JMS message (NOT in an XA transaction) 2) Perform EACH DB insert in a SEPARATE DB transaction 3) Acknowledge the JMS message

1) Read the JMS message in an XA transaction 2) In the SAME XA transaction, perform BOTH DB inserts but do NOT acknowledge the JMS message

1) Read and acknowledge the JMS message (NOT in an XA transaction) 2) In a NEW XA transaction, perform BOTH DB inserts

18. What operation can be performed through a JMX agent enabled in a Mule application?

View object store entries

Replay an unsuccessful message

Set a particular tog4J2 log level to TRACE

Deploy a Mule application

19. What condition requires using a CloudHub Dedicated Load Balancer?

When cross-region load balancing is required between separate deployments of the same Mule application

When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes

When API invocations across multiple CloudHub workers must be load balanced

When server-side load-balanced TLS mutual authentication is required between API implementations and API clients

20. An integration Mute application is being designed to process orders by submitting them to a backend system for offline processing. Each order will be received by the Mute application through an HTTPS POST and must be acknowledged immediately. Once acknowledged, the order will be submitted to a backend system. Orders that cannot be successfully submitted due to rejections from the backend system will need to be processed manually (outside the backend system).

The Mule application will be deployed to a customer-hosted runtime and is able to use an existing ActiveMQ broker if needed.

The backend system has a track record of unreliability both due to minor network connectivity issues and longer outages.

What idiomatic (used for their intended purposes) combination of Mule application components and ActiveMQ queues are required to ensure automatic submission of orders to the backend system, while minimizing manual order processing?

An On Error scope Non-persistent VM ActiveMQ Dead Letter Queue for manual processing

An On Error scope MuleSoft Object Store ActiveMQ Dead Letter Queue for manual processing

Until Successful component MuleSoft Object Store ActiveMQ is NOT needed or used

Until Successful component ActiveMQ long retry Queue ActiveMQ Dead Letter Queue for manual processing

21. Mule applications need to be deployed to CloudHub so they can access on-premises database systems. These systems store sensitive and hence tightly protected data, so are not accessible over the internet.

What network architecture supports this requirement?

An Anypoint VPC connected to the on-premises network using an IPsec tunnel or AWS DirectConnect, plus matching firewall rules in the VPC and on-premises network

Static IP addresses for the Mule applications deployed to the CloudHub Shared Worker Cloud, plus matching firewall rules and IP whitelisting in the on-premises network

An Anypoint VPC with one Dedicated Load Balancer fronting each on-premises database system, plus matching IP whitelisting in the load balancer and firewall rules in the VPC and on-premises network

Relocation of the database systems to a DMZ in the on-premises network, with Mule applications deployed to the CloudHub Shared Worker Cloud connecting only to the DMZ

22. A mule application is being designed to perform product orchestration. The Mule application needs to join together the responses from an inventory API and a Product Sales History API with the least latency.

To minimize the overall latency.

What is the most idiomatic (used for its intended purpose) design to call each API request in the Mule application?

Call each API request in a separate lookup call from Dataweave reduce operator

Call each API request in a separate route of a Scatter-Gather

Call each API request in a separate route of a Parallel For Each scope

Call each API request in a separate Async scope

23. 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?

Order messages are sent to an Anypoint MQ exchange OrderFulfilted messages are sent to an Anypoint MQ queue Both microservices interact with Anypoint MQ as the message broker, which must therefore scale to support the toad of both microservices

Older messages are sent directly to the Fulfillment microservices OrderFulfilled messages are sent directly to the Order microservice The Order microservice Interacts with one AMQP-compatible message broker and the Fulfillment microservice Interacts with a different AMQP-compatible message broker, so that both message brokers can be chosen and scaled to best support the toad each microservice

Order messages are sent to a JMS queue OrderFulfilled messages are sent to a JMS topic Both microservices Interact with the same JMS provider (message broker) Instance, which must therefore scale to support the load of both microservices

Order messages are sent to a JMS queue OrderFulfilled messages are sent to a JMS topic The Order microservice Interacts with one JMS provider (message broker) and the Fulfillment microservice interacts with a different JMS provider, so that both message brokers can be chosen and scaled to best support the load of each microservice

24. An organization is creating a set of new services that are critical for their business. The project team prefers using REST for all services but is willing to use SOAP with common WS-" standards if a particular service requires it.

What requirement would drive the team to use SOAP/WS-* for a particular service?

Must use XML payloads for the service and ensure that it adheres to a specific schema

Must publish and share the service specification (including data formats) with the consumers of the service

Must support message acknowledgement and retry as part of the protocol

Must secure the service, requiring all consumers to submit a valid SAML token

25. A Mule application is synchronizing customer data between two different database systems.

What is the main benefit of using eXtended Architecture (XA) transactions over local transactions to synchronize these two different database systems?

An XA transaction synchronizes the database systems with the least amount of Mule configuration or coding

An XA transaction handles the largest number of requests in the shortest time

An XA transaction automatically rolls back operations against both database systems if any operation falls

An XA transaction writes to both database systems as fast as possible

26. An Integration Mule application is being designed to synchronize customer data between two systems. One system is an IBM Mainframe and the other system is a Salesforce Marketing Cloud (CRM) instance. Both systems have been deployed in their typical configurations, and are to be invoked using the native protocols provided by Salesforce and IBM.

What interface technologies are the most straightforward and appropriate to use in this Mute application to interact with these systems, assuming that Anypoint Connectors exist that implement these interface technologies?

IBM: DB access CRM: gRPC

IBM: REST CRM:REST

IBM: Active MQ CRM: REST

IBM:QCS CRM: SOAP

27. To implement predictive maintenance on its machinery equipment, ACME Tractors has installed thousands of IoT sensors that will send data for each machinery asset as sequences of JMS messages, in near real-time, to a JMS queue named SENSOR_DATA on a JMS server. The Mule application contains a JMS Listener operation configured to receive incoming messages from the JMS servers SENSOR_DATA JMS queue. The Mule application persists each received JMS message, then sends a transformed version of the corresponding Mule event to the machinery equipment back-end systems.

The Mule application will be deployed to a multi-node, customer-hosted Mule runtime cluster. Under normal conditions, each JMS message should be processed exactly once.

How should the JMS Listener be configured to maximize performance and concurrent message processing of the JMS queue?

Set numberOfConsumers = 1 Set primaryNodeOnly = false

Set numberOfConsumers = 1 Set primaryNodeOnly = true

Set numberOfConsumers to a value greater than one Set primaryNodeOnly = true

Set numberOfConsumers to a value greater than one Set primaryNodeOnly = false

28. 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?

First Successful router in the parent flow On Error Continue error handler in the child flow

For Each scope in the parent flow On Error Continue error handler in the child flow

Parallel For Each scope in the parent flow On Error Propagate error handler in the child flow

Until Successful router in the parent flow On Error Propagate error handler in the child flow

29. The ABC company has an Anypoint Runtime Fabric on VMs/Bare Metal (RTF-VM) appliance installed on its own customer-hosted AWS infrastructure.

Mule applications are deployed to this RTF-VM appliance. As part of the company standards, the Mule application logs must be forwarded to an external log management tool (LMT).

Given the company's current setup and requirements, what is the most idiomatic (used for its intended purpose) way to send Mule application logs to the external LMT?

In RTF-VM, install and configure the external LTM's log-forwarding agent

In RTF-VM, edit the pod configuration to automatically install and configure an Anypoint Monitoring agent

In each Mule application, configure custom Log4j settings

In RTF-V

configure the out-of-the-box external log forwarder

30. 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?

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

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

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

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

31. An API client is implemented as a Mule application that includes an HTTP Request operation using a default configuration. The HTTP Request operation invokes an external API that follows standard HTTP status code conventions, which causes the HTTP Request operation to return a 4xx status code.

What is a possible cause of this status code response?

An error occurred inside the external API implementation when processing the HTTP request that was received from the outbound HTTP Request operation of the Mule application

The external API reported that the API implementation has moved to a different external endpoint

The HTTP response cannot be interpreted by the HTTP Request operation of the Mule application after it was received from the external API

The external API reported an error with the HTTP request that was received from the outbound HTTP Request operation of the Mule application

32. What is required before an API implemented using the components of Anypoint Platform can be managed and governed (by applying API policies) on Anypoint Platform?

The API must be published to Anypoint Exchange and a corresponding API instance ID must be obtained from API Manager to be used in the API implementation

The API implementation source code must be committed to a source control management system (such as GitHub)

A RAML definition of the API must be created in API designer so it can then be published to Anypoint Exchange

The API must be shared with the potential developers through an API portal so API consumers can interact with the API

33. 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?

Use an in-memory repeatable stream

Use a file-stored non-repeatable stream

Use an in-memory non-repeatable stream

Use a file-stored repeatable stream

34. Refer to the exhibit.

A Mule application is deployed to a cluster of two customer-hosted Mute runtimes. The Mute application has a flow that polls a database and another flow with an HTTP Listener.

HTTP clients send HTTP requests directly to individual cluster nodes.

What happens to database polling and HTTP request handling in the time after the primary (master) node of the cluster has railed, but before that node is restarted?

Database polling continues Only HTTP requests sent to the remaining node continue to be accepted

Database polling stops All HTTP requests continue to be accepted

Database polling continues All HTTP requests continue to be accepted, but requests to the failed node Incur increased latency

Database polling stops All HTTP requests are rejected

35. A mule application is deployed to a Single Cloudhub worker and the public URL appears in Runtime Manager as the APP URL.

Requests are sent by external web clients over the public internet to the mule application App url. Each of these requests routed to the HTTPS Listener event source of the running Mule application.

Later, the DevOps team edits some properties of this running Mule application in Runtime Manager.

Immediately after the new property values are applied in runtime manager, how is the current Mule application deployment affected and how will future web client requests to the Mule application be handled?

Cloudhub will redeploy the Mule application to the OLD Cloudhub worker New web client requests will RETURN AN ERROR until the Mule application is redeployed to the OLD Cloudhub worker

CloudHub will redeploy the Mule application to a NEW Cloudhub worker New web client requests will RETURN AN ERROR until the NEW Cloudhub worker is available

Cloudhub will redeploy the Mule application to a NEW Cloudhub worker New web client requests are ROUTED to the OLD Cloudhub worker until the NEW Cloudhub worker is available.

Cloudhub will redeploy the mule application to the OLD Cloudhub worker New web client requests are ROUTED to the OLD Cloudhub worker BOTH before and after the Mule application is redeployed.

36. An organization's security policies mandate complete control of the login credentials used to log in to Anypoint Platform.

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.

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.

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

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

39. An API has been unit tested and is ready for integration testing. The API is governed by a Client ID Enforcement policy in all environments.

What must the testing team do before they can start integration testing the API in the Staging environment?

They must access the API portal and create an API notebook using the Client ID and Client Secret supplied by the API portal in the Staging environment

They must request access to the API instance in the Staging environment and obtain a Client ID and Client Secret to be used for testing the API

They must be assigned as an API version owner of the API in the Staging environment

They must request access to the Staging environment and obtain the Client ID and Client Secret for that environment to be used for testing the API
