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

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

10. Refer to the exhibit.

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

11. 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

To directly reference one shared and customized log4j2.xml file from multiple Mule applications

17. 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

18. Refer to the exhibit.

A business process involves the receipt of a file from an external vendor over SFTP. The file needs to be parsed and its content processed, validated, and ultimately persisted to a database. The delivery mechanism is expected to change in the future as more vendors send similar files using other mechanisms such as file transfer or HTTP POST.

What is the most effective way to design for these requirements in order to minimize the impact of future change?

Use a MuleSoft Scatter-Gather and a MuleSoft Batch Job to handle the different files coming from different sources

Create a Process API to receive the file and process it using a MuleSoft Batch Job while delegating the data save process to a System API

Use a composite data source so files can be retrieved from various sources and delivered to a MuleSoft Batch Job for processing

19. Refer to the exhibit.

A shopping cart checkout process consists of a web store backend sending a sequence of API invocations to an Experience API, which in turn invokes a Process API. All API invocations are over HTTPS POST. The Java web store backend executes in a Java EE application server, while all API implementations are Mule applications executing in a customer -hosted Mule runtime. End-to-end correlation of all HTTP requests and responses belonging to each individual checkout Instance is required. This is to be done through a common correlation ID, so that all log entries written by the web store backend, Experience API implementation, and Process API implementation include the same correlation ID for all requests and responses belonging to the same checkout instance.

What is the most efficient way (using the least amount of custom coding or configuration) for the web store backend and the implementations of the Experience API and Process API to participate in end-to-end correlation of the API invocations for each checkout instance?

A) The web store backend, being a Java EE application, automatically makes use of the thread-local correlation ID generated by the Java EE application server and automatically transmits that to the Experience API using HTTP-standard headers

No special code or configuration is included in the web store backend, Experience API, and Process API implementations to generate and manage the correlation ID

B) The web store backend generates a new correlation ID value at the start of checkout and sets it on the X-CORRELATlON-lt HTTP request header In each API invocation belonging to that checkout

No special code or configuration is included in the Experience API and Process API implementations to generate and manage the correlation ID

C) The Experience API implementation generates a correlation ID for each incoming HTTP request and passes it to the web store backend in the HTTP response, which includes it in all subsequent API invocations to the Experience API.

The Experience API implementation must be coded to also propagate the correlation ID to the Process API in a suitable HTTP request header

D) The web store backend sends a correlation ID value in the HTTP request body In the way required by the Experience API

The Experience API and Process API implementations must be coded to receive the custom correlation ID In the HTTP requests and propagate It in suitable HTTP request headers

Option A

Option B

Option C

Option D

20. 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

21. Refer to the exhibit.

A Mule application is deployed to a multi-node Mule runtime cluster. The Mule application uses the competing consumer pattern among its cluster replicas to receive JMS messages from a JMS queue. To process each received JMS message, the following steps are performed in a flow: Step l: The JMS Correlation ID header is read from the received JMS message.

Step 2: The Mule application invokes an idempotent SOAP webservice over HTTPS, passing the JMS Correlation ID as one parameter in the SOAP request.

Step 3: The response from the SOAP webservice also returns the same JMS Correlation ID.

Step 4: The JMS Correlation ID received from the SOAP webservice is validated to be identical to the JMS Correlation ID received in Step 1.

Step 5: The Mule application creates a response JMS message, setting the JMS Correlation ID message header to the validated JMS Correlation ID and publishes that message to a response JMS queue.

Where should the Mule application store the JMS Correlation ID values received in Step 1 and Step 3 so that the validation in Step 4 can be performed, while also making the overall Mule application highly available, fault-tolerant, performant, and maintainable?

Both Correlation ID values should be stored in a persistent object store

Both Correlation ID values should be stored In a non-persistent object store

The Correlation ID value in Step 1 should be stored in a persistent object store The Correlation ID value in step 3 should be stored as a Mule event variable/attribute

Both Correlation ID values should be stored as Mule event variable/attribute

22. 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

23. What comparison is true about a CloudHub Dedicated Load Balancer (DLB) vs. the CloudHub Shared Load Balancer (SLB)?

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

26. 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

27. Refer to the exhibit.

A business process involves two APIs that interact with each other asynchronously over HTTP. Each API is implemented as a Mule application. API 1 receives the initial HTTP request and invokes API 2 (in a fire and forget fashion) while API 2, upon completion of the processing, calls back into API l to notify about completion of the asynchronous process.

Each API Is deployed to multiple redundant Mule runtimes and a separate load balancer, and is deployed to a separate network zone.

In the network architecture, how must the firewall rules be configured to enable the above Interaction between API 1 and API 2?

To authorize the certificate to be used both APIs

To enable communication from each API’s Mule Runtimes and Network zone to the load balancer of the other API

To open direct two-way communication between the Mule Runtimes of both API’s

To allow communication between load balancers used by each API

28. 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

Dedicated Load Balancer setup

31. Mule application A receives a request Anypoint MQ message REQU with a payload containing a variable-length list of request objects. Application A uses the For Each scope to split the list into individual objects and sends each object as a message to an Anypoint MQ queue.

Service S listens on that queue, processes each message independently of all other messages, and sends a response message to a response queue.

Application A listens on that response queue and must in turn create and publish a response Anypoint MQ message RESP with a payload containing the list of responses sent by service S in the same order as the request objects originally sent in REQU.

Assume successful response messages are returned by service S for all request messages.

What is required so that application A can ensure that the length and order of the list of objects in RESP and REQU match, while at the same time maximizing message throughput?

Use a Scatter-Gather within the For Each scope to ensure response message order Configure the Scatter-Gather with a persistent object store

Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU

Use an Async scope within the For Each scope and collect response messages in a second For Each scope in the order In which they arrive, then send RESP using this list of responses

Keep track of the list length and all object indices in REQU, both in the For Each scope and in all communication involving service Use persistent storage when creating RESP

32. Refer to the exhibit.

A Mule application is being designed to expose a SOAP web service to its clients.

What language is typically used inside the web service's interface definition to define the data structures that the web service Is expected to exchange with its clients?

33. 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

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 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.

What is the most appropriate way to implement persistence for the watermark in order to support the required data replication integration logic?

Persistent Anypoint MQ Queue

Persistent Object Store

Persistent Cache Scope

Persistent VM Queue

37. A new Mule application under development must implement extensive data transformation logic. Some of the data transformation functionality is already available as external transformation services that are mature and widely used across the organization; the rest is highly specific to the new Mule application.

The organization follows a rigorous testing approach, where every service and application must be extensively acceptance tested before it is allowed to go into production.

What is the best way to implement the data transformation logic for this new Mule application while minimizing the overall testing effort?

Implement and expose all transformation logic as mlaoservices using DataWeave, so it can be reused by any application component that needs it, including the new Mule application

Implement transformation logic in the new Mute application using DataWeave, replicating the transformation logic of existing transformation services

Extend the existing transformation services with new transformation logic and Invoke them from the new Mule application

Implement transformation logic in the new Mute application using DataWeave, invoking existing transformation services when possible

45. A Mule application contains a Batch Job with two Batch Steps (Batch_Step_l and Batch_Step_2). A payload with 1000 records is received by the Batch Job.

How many threads are used by the Batch Job to process records, and how does each Batch Step process records within the Batch Job?

Each Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and RECORDS are processed IN PARALLEL within and between the two Batch Steps

Each Batch Job uses a SINGLE THREAD for all Batch steps Each Batch step instance receives ONE record at a time as the payload, and RECORDS are processed IN ORDER, first through Batch_Step_l and then through Batch_Step_2

Each Batch Job uses a SINGLE THREAD to process a configured block size of record Each Batch Step instance receives A BLOCK OF records as the payload, and BLOCKS of records are processed IN ORDER

Each Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and BATCH STEP INSTANCES execute IN PARALLEL to process records and Batch Steps in ANY order as fast as possible

46. 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?

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.

98. An organization has several APIs that accept JSON data over HTTP POST. The APIs are all publicly available and are associated with several mobile applications and web applications. The organization does NOT want to use any authentication or compliance policies for these APIs, but at the same time, is worried that some bad actor could send payloads that could somehow compromise the applications or servers running the API implementations.

What out-of-the-box Anypoint Platform policy can address exposure to this threat?

Apply a Header injection and removal policy that detects the malicious data before it is used

Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors

Shut out bad actors by using HTTPS mutual authentication for all API invocations

Apply a JSON threat protection policy to all APIs to detect potential threat vectors

99. 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

100. An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the API's public portal. The API endpoint does NOT change in the new version.

How should the developer of an API client respond to this change?

The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run.

The API producer should be contacted to understand the change to existing functionality.

The API producer should be requested to run the old version in parallel with the new one.

The API client code ONLY needs to be changed if it needs to take advantage of new features.
