1. A set of integration Mule applications, some of which expose APIs, are being created to enable a new business process. Various stakeholders may be impacted by this. These stakeholders are a combination of semi-technical users (who understand basic integration terminology and concepts such as JSON and XML) and technically skilled potential consumers of the Mule applications and APIs.

What Is an effective way for the project team responsible for the Mule applications and APIs being built to communicate with these stakeholders using Anypoint Platform and its supplied toolset?

Use Anypoint Design Center to implement the Mule applications and APIs and give the various stakeholders access to these Design Center projects, so they can collaborate and provide feedback

Create Anypoint Exchange entries with pages elaborating the integration design, including API notebooks (where applicable) to help the stakeholders understand and interact with the Mule applications and APIs at various levels of technical depth

Use Anypoint Exchange to register the various Mule applications and APIs and share the RAML definitions with the stakeholders, so they can be discovered

Capture documentation about the Mule applications and APIs inline within the Mule integration flows and use Anypoint Studio's Export Documentation feature to provide an HTML version of this documentation to the stakeholders

2. A REST API is being designed to implement a Mule application.

What standard interface definition language can be used to define REST APIs?

Web Service Definition Language (WSDL)

OpenAPI Specification (OAS)

YAML

AsyncAPI Specification

XSD

JSON Schema

RAMI

5. What API policy would LEAST likely be applied to a Process API?

Custom circuit breaker

Client ID enforcement

Rate limiting

6. 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

7. The implementation of a Process API must change .

What is a valid approach that minimizes the impact of this change on API clients?

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

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

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

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

8. A Mule application name Pub uses a persistence object store. The Pub Mule application is deployed to Cloudhub and it configured to use Object Store v2.

Another Mule application name sub is being developed to retrieve values from the Pub Mule application persistence object Store and will also be deployed to cloudhub.

What is the most direct way for the Sub Mule application to retrieve values from the Pub Mule application persistence object store with the least latency?

Use an object store connector configured to access the Pub Mule application persistence object store

Use a VM connector configured to directly access the persistence queue of the Pub Mule application persistence object store.

Use an Anypoint MQ connector configured to directly access the Pub Mule application persistence object store

Use the Object store v2 REST API configured to access the Pub Mule application persistence object store.

9. An organization has various integrations implemented as Mule applications. Some of these Mule applications are deployed to custom hosted Mule runtimes (on-premises) while others execute in the MuleSoft-hosted runtime plane (CloudHub). To perform the Integra functionality, these Mule applications connect to various backend systems, with multiple applications typically needing to access the backend systems.

How can the organization most effectively avoid creating duplicates in each Mule application of the credentials required to access the backend systems?

Create a Mule domain project that maintains the credentials as Mule domain-shared resources Deploy the Mule applications to the Mule domain, so the credentials are available to the Mule applications

Store the credentials in properties files in a shared folder within the organization's data center Have the Mule applications load properties files from this shared location at startup

Segregate the credentials for each backend system into environment-specific properties files Package these properties files in each Mule application, from where they are loaded at startup

Configure or create a credentials service that returns the credentials for each backend system, and that is accessible from customer-hosted and MuleSoft-hosted Mule runtimes Have the Mule applications toad the properties at startup by invoking that credentials service

10. 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

11. Organization wants to achieve high availability goal for Mule applications in customer hosted runtime plane. Due to the complexity involved, data cannot be shared among of different instances of same Mule application .

What option best suits to this requirement considering high availability is very much critical to the organization?

The cluster can be configured

Use third party product to implement load balancer

High availability can be achieved only in CloudHub

Use persistent object store

12. 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

13. An organization's governance process requires project teams to get formal approval from all key stakeholders for all new Integration design specifications. An integration Mule application Is being designed that interacts with various backend systems. The Mule application will be created using Anypoint Design Center or Anypoint Studio and will then be deployed to a customer-hosted runtime.

What key elements should be included in the integration design specification when requesting approval for this Mule application?

SLAs and non-functional requirements to access the backend systems

Snapshots of the Mule application's flows, including their error handling

A list of current and future consumers of the Mule application and their contact details

The credentials to access the backend systems and contact details for the administrator of each system

Replay an unsuccessful message

Set a particular tog4J2 log level to TRACE

Deploy a Mule application

15. A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity. The first of these downstream APIs offers the following SLA for its response time: median: 100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.

If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

Set a timeout of 100 ms; that leaves 400 ms for the other two downstream APIs to complete

Do not set a timeout; the Invocation of this API Is mandatory and so we must wait until it responds

Set a timeout of 50 ms; this times out more invocations of that API but gives additional room for retries

No timeout is possible to meet the upstream API's desired SLA; a different SLA must be negotiated with the first downstream API or invoke an alternative API

16. A global organization operates datacenters in many countries. There are private network links between these datacenters because all business data (but NOT metadata) must be exchanged over these private network connections.

The organization does not currently use AWS in any way.

The strategic decision has Just been made to rigorously minimize IT operations effort and investment going forward.

What combination of deployment options of the Anypoint Platform control plane and runtime plane(s) best serves this organization at the start of this strategic journey?

MuleSoft-hosted Anypoint Platform control plane CloudHub Shared Worker Cloud in multiple AWS regions

Anypoint Platform- Private Cloud Edition Customer-hosted runtime plane in each datacenter

17. A Mule application is being designed To receive nightly a CSV file containing millions of records from an external vendor over SFTP, The records from the file need to be validated, transformed. And then written to a database. Records can be inserted into the database in any order.

In this use case, what combination of Mule components provides the most effective and performant way to write these records to the database?

Use a Parallel for Each scope to Insert records one by one into the database

Use a Scatter-Gather to bulk insert records into the database

Use a Batch job scope to bulk insert records into the database.

Use a DataWeave map operation and an Async scope to insert records one by one into the database.

18. Additional nodes are being added to an existing customer-hosted Mule runtime cluster to improve performance. Mule applications deployed to this cluster are invoked by API clients through a load balancer.

What is also required to carry out this change?

A new load balancer must be provisioned to allow traffic to the new nodes in a round-robin fashion

External monitoring tools or log aggregators must be configured to recognize the new nodes

API implementations using an object store must be adjusted to recognize the new nodes and persist to them

New firewall rules must be configured to accommodate communication between API clients and the new nodes

19. An integration Mute application consumes and processes a list of rows from a CSV file. Each row must be read from the CSV file, validated, and the row data sent to a JMS queue, in the exact order as in the CSV file.

If any processing step for a row falls, then a log entry must be written for that row, but processing of other rows must not be affected.

What combination of Mute components is most idiomatic (used according to their intended purpose) when Implementing the above requirements?

Scatter-Gather component On Error Continue scope

VM connector first Successful scope On Error Propagate scope

For Each scope On Error Continue scope

Async scope On Error Propagate scope

20. 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

One of the backend systems invoked by an API implementation enforces rate limits on the number of requests a particular client can make. Both the backend system and the API implementation are deployed to several non-production environments in addition to production.

Rate limiting of the backend system applies to all non-production environments. The production environment, however, does NOT have any rate limiting.

What is the most effective approach to conduct performance tests of the API implementation in a staging (non-production) environment?

Create a mocking service that replicates the backend system's production performance characteristics. Then configure the API implementation to use the mocking service and conduct the performance tests

Use MUnit to simulate standard responses from the backend system then conduct performance tests to identify other bottlenecks in the system

Include logic within the API implementation that bypasses invocations of the backend system in a performance test situation. Instead invoking local stubs that replicate typical backend system responses then conduct performance tests using this API Implementation

Conduct scaled-down performance tests in the staging environment against the rate limited backend system then upscale performance results to full production scale

25. Refer to the exhibit.

This Mule application is deployed to multiple Cloudhub workers with persistent queue enabled. The retrievefile flow event source reads a CSV file from a remote SFTP server and then publishes each record in the CSV file to a VM queue. The processCustomerRecords flow’s VM Listner receives messages from the same VM queue and then processes each message separately.

How are messages routed to the cloudhub workers as messages are received by the VM Listener?

Each message is routed to ONE of the Cloudhub workers in a DETERMINSTIC round robin fashion thereby EXACTLY BALANCING messages among the cloudhub workers

Each messages routes to ONE of the available Clouhub workers in a NON-DETERMINSTIC non round-robin fashion thereby APPROXIMATELY BALANCING messages among the cloudhub workers

Each message is routed to the SAME Cloudhub worker that retrieved the file, thereby BINDING ALL messages to ONLY that ONE Cloudhub worker

Each message is duplicated to ALL of the Cloudhub workers, thereby SHARING EACH message with ALL the Cloudhub workers.

26. 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.

28. A global, high-volume shopping Mule application is being built and will be deployed to CloudHub. To improve performance, the Mule application uses a Cache scope that maintains cache state in a CloudHub object store. Web clients will access the Mule application over HTTP from all around the world, with peak volume coinciding with business hours in the web client's geographic location.

To achieve optimal performance, what Anypoint Platform region should be chosen for the CloudHub object store?

Choose the same region as to where the Mule application is deployed

Choose the US-West region, the only supported region for CloudHub object stores

Encryption of both HTTP request and HTTP response bodies for all HTTP clients

Encryption of both HTTP request header and HTTP request body for all HTTP clients

30. What Is a recommended practice when designing an integration Mule 4 application that reads a large XML payload as a stream?

The payload should be dealt with as a repeatable XML stream, which must only be traversed (iterated-over) once and CANNOT be accessed randomly from DataWeave expressions and scripts

The payload should be dealt with as an XML stream, without converting it to a single Java object (POJO)

The payload size should NOT exceed the maximum available heap memory of the Mute runtime on which the Mule application executes

The payload must be cached using a Cache scope If It Is to be sent to multiple backend systems

31. An organization is designing the following two Mule applications that must share data via a common persistent object store instance:

- Mule application P will be deployed within their on-premises datacenter.

- Mule application C will run on CloudHub in an Anypoint VPC.

The object store implementation used by CloudHub is the Anypoint Object Store v2 (OSv2).

what type of object store(s) should be used, and what design gives both Mule applications access to the same object store instance?

Application P uses the Object Store connector to access a persistent object store Application C accesses this persistent object store via the Object Store REST API through an IPsec tunnel

Application C and P both use the Object Store connector to access the Anypoint Object Store v2

Application C uses the Object Store connector to access a persistent object Application P accesses the persistent object store via the Object Store REST API

Application C and P both use the Object Store connector to access a persistent object store

32. 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.

37. 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?

EACH item VM message is processed AT MOST ONCE by ONE CloudHub worker, with workers chosen in a deterministic round-robin fashion Each of the four CloudHub workers can be expected to process 1/4 of the Item VM messages (about 50 items)

EACH item VM message is processed AT LEAST ONCE by ONE ARBITRARY CloudHub worker Each of the four CloudHub workers can be expected to process some item VM messages

ALL Item VM messages are processed AT LEAST ONCE by the SAME CloudHub worker where the parent flow was invoked This one CloudHub worker processes ALL 200 item VM messages

ALL item VM messages are processed AT MOST ONCE by ONE ARBITRARY CloudHub worker This one CloudHub worker processes ALL 200 item VM messages

38. Insurance organization is planning to deploy Mule application in MuleSoft Hosted runtime plane. As a part of requirement, application should be scalable. highly available. It also has regulatory requirement which demands logs to be retained for at least 2 years. As an Integration Architect what step you will recommend in order to achieve this?

It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required.

When deploying an application to CloudHub, logs retention period should be selected as 2 years

When deploying an application to CloudHub, worker size should be sufficient to store 2 years data

Logging strategy should be configured accordingly in log4j file deployed with the application.

39. In a Mule Application, a flow contains two (2) JMS consume operations that are used to connect to a JMS broker and consume messages from two (2) JMS destination. The Mule application then joins the two JMS messages together.

The JMS broker does not implement high availability (HA) and periodically experiences scheduled outages of upto 10 mins for routine maintenance.

What is the most idiomatic (used for its intented purpose) way to build the mule flow so it can best recover from the expected outages?

Configure a reconnection strategy for the JMS connector

Enclose the two(2) JMS operation in an Until Successful scope

Consider a transaction for the JMS connector

Enclose the two(2) JMS operations in a Try scope with an Error Continue error handler
