NO.39 Which component of Anypoint platform belongs to the platform control plane?

Runtime Fabric

Runtime Replica

Anypoint Connectors

API Manager

NO.40 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

NO.41 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 therunning 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 webclient 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 afterthe Mule application is redeployed.

NO.42 Refer to the exhibit.

A Mule application is being designed to be deployed to several CIoudHub workers. The Mule application’s integration logic is to replicate changed Accounts from Satesforce to a backend system every 5 minutes.
A watermark will be used to only retrieve those Satesforce Accounts that have been modified since the last time the integration logic ran.
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

NO.43 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: CICS CRM: SOAP

Correct answer is IBM: CICS CRM: SOAP
* Within Anypoint Exchange, MuleSoft offers the IBM CICS connector. Anypoint Connector for IBM CICS Transaction Gateway (IBM CTG Connector) provides integration with back-end CICS apps using the CICS Transaction Gateway.
* Anypoint Connector for Salesforce Marketing Cloud (Marketing Cloud Connector) enables you to connect to the Marketing Cloud API web services (now known as the Marketing Cloud API), which is also known as the Salesforce Marketing Cloud. This connector exposes convenient operations via SOAP for exploiting the capabilities of Salesforce Marketing Cloud.

NO.44 An organization is not meeting its growth and innovation objectives because IT cannot deliver projects last enough to keep up with the pace of change required by the business.
According to MuleSoft’s IT delivery and operating model, which step should the organization lake to solve this problem?

Modify IT governance and security controls so that line of business developers can have direct access to the organization’s systems of record

Switch from a design-first to a code-first approach for IT development

Adopt a new approach that decouples core IT projects from the innovation that happens within each line of business

Hire more |T developers, architects, and project managers to increase IT delivery

NO.45 A developer needs to discover which API specifications have been created within the organization before starting a new project.
Which Anypoint Platform component can the developer use to find and try out the currently released API specifications?

Anypoint Exchange

Runtime Manager

API Manager

Object Store

NO.46 Refer to the exhibit.

Anypoint Platform supports role-based access control (RBAC) to features of the platform. An organization has configured an external Identity Provider for identity management with Anypoint Platform.
What aspects of RBAC must ALWAYS be controlled from the Anypoint Platform control plane and CANNOT be controlled via the external Identity Provider?

Controlling the business group within Anypoint Platform to which the user belongs

Assigning Anypoint Platform permissions to a role

Assigning Anypoint Platform role(s) to a user

Removing a user’s access to Anypoint Platform when they no longer work for the organization

* By default, Anypoint Platform performs its own user management
– For user management, one external IdP can be integrated with the Anypoint Platform organization (note: not at business group level)
– Permissions and access control are still enforced inside Anypoint Platform and CANNOT be controlled via the external Identity Provider * As the Anypoint Platform organization administrator, you can configure identity management in Anypoint Platform to set up users for single sign-on (SSO). * You can map users in a federated organization’s group to a role which also gives the flexibility of controlling the business group within Anypoint Platform to which the user belongs to. Also user can nbe removed from external identity management system when they no longer work for the organization. So they wont be able to authenticate using SSO to login to Anypoint Platform. * Using external identity we can no change permissions of a particular role in Mulesoft Anypoint platform.
* So Correct answer is Assigning Anypoint Platform permissions to a role

NO.47 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?

O 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

NO.48 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

NO.49 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

* To send message or receive JMS (Java Message Service) message no separate network connection need to be established. So option A, C and D are ruled out.
Correct answer: The JMS connector supports both sending and receiving of JMS
* JMS Connector enables sending and receiving messages to queues and topics for any message service that implements the JMS specification.
* JMS is a widely used API for message-oriented middleware.
* It enables the communication between different components of a distributed application to be loosely coupled, reliable, and asynchronous.

NO.50 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

Create an API that receives the file and invokes a Process API with the data contained In the file, then have the Process API process the data using a MuleSoft Batch Job and other System APIs as needed

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

NO.51 Refer to the exhibit.

An organization uses a 2-node Mute runtime cluster to host one stateless API implementation. The API is accessed over HTTPS through a load balancer that uses round-robin for load distribution.
Two additional nodes have been added to the cluster and the load balancer has been configured to recognize the new nodes with no other change to the load balancer.
What average performance change is guaranteed to happen, assuming all cluster nodes are fully operational?

50% reduction in the response time of the API

100% increase in the throughput of the API

50% reduction In the JVM heap memory consumed by each node

50% reduction In the number of requests being received by each node

NO.52 Which Exchange asset type represents configuration modules that extend the functionality of an API and enforce capabilities such as security?

Rulesets

Policies

RESTAPIs

Connectors

NO.53 An organization has implemented the cluster with two customer hosted Mule runtimes is hosting an application.
This application has a flow with a JMS listener configured to consume messages from a queue destination. As an integration architect can you advise which JMS listener configuration must be used to receive messages in all the nodes of the cluster?

Use the parameter primaryNodeOnly= “false” on the JMS listener

Use the parameter primaryNodeOnly= “false” on the JMS listener with a shared subscription

Use the parameter primaryNodeOnly= “true” on the JMS listener with a nonshared subscription

Use the parameter primaryNodeOnly= “true” on the JMS listener

NO.54 What requires configuration of both a key store and a trust store for an HTTP Listener?

Support for TLS mutual (two-way) authentication with HTTP clients

Encryption of requests to both subdomains and API resource endpoints fhttPs://aDi.customer.com/ and https://customer.com/api)

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

1 way SSL : The server presents its certificate to the client and the client adds it to its list of trusted certificate. And so, the client can talk to the server.
2-way SSL: The same principle but both ways. i.e. both the client and the server has to establish trust between themselves using a trusted certificate. In this way of a digital handshake, the server needs to present a certificate to authenticate itself to client and client has to present its certificate to server.
* TLS is a cryptographic protocol that provides communications security for your Mule app.
* TLS offers many different ways of exchanging keys for authentication, encrypting data, and guaranteeing message integrity Keystores and Truststores Truststore and keystore contents differ depending on whether they are used for clients or servers:
For servers: the truststore contains certificates of the trusted clients, the keystore contains the private and public key of the server. For clients: the truststore contains certificates of the trusted servers, the keystore contains the private and public key of the client.
Adding both a keystore and a truststore to the configuration implements two-way TLS authentication also known as mutual authentication.
* in this case, correct answer is Support for TLS mutual (two-way) authentication with HTTP clients.

NO.55 A Mule application uses an HTTP Request operation to invoke an external API.
The external API follows the HTTP specification for proper status code usage.
What is a possible cause when a 3xx status code is returned to the HTTP Request operation from the external API?

The request was ACCEPTED by the external API

The request was REDIRECTED to a different URL by the external API

The request was NOT RECEIVED by the external API

The request was NOT ACCEPTED by the external API

Explanation/Reference: https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

NO.56 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

Security Assertion Markup Language (SAML) is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP).
SAML transactions use Extensible Markup Language (XML) for standardized communications between the identity provider and service providers.
SAML is the link between the authentication of a user’s identity and the authorization to use a service.
WS-Security is the key extension that supports many authentication models including: basic username/password credentials, SAML, OAuth and more.
A common way that SOAP API’s are authenticated is via SAML Single Sign On (SSO). SAML works by facilitating the exchange of authentication and authorization credentials across applications. However, there is no specification that describes how to add SAML to REST web services.

NO.57 What operation can be performed through a JMX agent enabled in a Mule application?
