Question 1

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?

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

BUse the WSS module

CUse the Java module

DUse the Transform Message component

Answer : A

Question 2

When using Anypoint Platform across various lines of business with their own Anypoint Platform business groups, what configuration of Anypoint Platform is always performed at the organization level as opposed to at the business group level?

AEnvironment setup

BIdentity management setup

CRole and permission setup

DDedicated Load Balancer setup

Answer : B

* Roles are business group specific. Configure identity management in the Anypoint Platform master organization. As the Anypoint Platform organization administrator, you can configure identity management in Anypoint Platform to set up users for single sign-on (SSO). * Roles and permissions can be set up at business group and organization level also. But Identity Management setup is only done at Organization level * Business groups are self-contained resource groups that contain Anypoint Platform resources such as applications and APIs. Business groups provide a way to separate and control access to Anypoint Platform resources because users have access only to the busine

Question 3

An organization is creating a Mule application that will be deployed to CloudHub. The Mule application has a property named dbPassword that stores a database user's password.

The organization's security standards indicate that the dbPassword property must be hidden from every Anypoint Platform user after the value is set in the Runtime Manager Properties tab.

What configuration in the Mule application helps hide the dbPassword property value in Runtime Manager?

AUse secure::dbPassword as the property placeholder name and store the cleartext (unencrypted) value in a secure properties placeholder file

BUse secure::dbPassword as the property placeholder name and store the property encrypted value in a secure properties placeholder file

CAdd the dbPassword property to the secureProperties section of the pom.xml file

DAdd the dbPassword property to the secureProperties section of the mule-artifact.json file

Answer : B

Question 4

According to MuleSoft, which major benefit does a Center for Enablement (C4E) provide for an enterprise and its lines of business?

AEnabling Edge security between the lines of business and public devices

BCentralizing project management across the lines of business

CCentrally managing return on investment (ROI) reporting from lines of business to leadership

DAccelerating self-service by the lines of business

Answer : B

Question 5

What requires configuration of both a key store and a trust store for an HTTP Listener?

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

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

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

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

Answer : A

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

Question 6

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?

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

BDatabase polling stops All HTTP requests continue to be accepted

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

DDatabase polling stops All HTTP requests are rejected

Answer : A

Correct answer is Database polling continues Only HTTP requests sent to the remaining node continue to be accepted. : Architecture descripted in the question could be described as follows.When node 1 is down , DB polling will still continue via node 2 . Also requests which are coming directly to node 2 will also be accepted and processed in BAU fashion. Only thing that wont work is when requests are sent to Node 1 HTTP connector. The flaw with this architecture is HTTP clients are sending HTTP requests directly to individual cluster nodes. By default, clustering Mule runtime engines ensures high system availability. If a Mule runtime engine node becomes unavailable due to failure or planned downtime, another node in the cluster can assume the workload and continue to process existing events and messages

Question 7

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?

ASet numberOfConsumers = 1
Set primaryNodeOnly = false

BSet numberOfConsumers = 1
Set primaryNodeOnly = true

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

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