1. 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

2. 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

3. 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

4. When designing an upstream API and its implementation, the development team has been advised to not set timeouts when invoking downstream API. Because the downstream API has no SLA that can be relied upon. This is the only donwstream API dependency of that

upstream API. Assume the downstream API runs uninterrupted without crashing .

What is the impact of this advice?

The invocation of the downstream API will run to completion without timing out.

An SLA for the upstream API CANNOT be provided.

A default timeout of 500 ms will automatically be applied by the Mule runtime in which the upstream API implementation executes.

A load-dependent timeout of less than 1000 ms will be applied by the Mule runtime in which the downstream API implementation executes.

5. A company wants its users to log in to Anypoint Platform using the company's own internal user credentials. To achieve this, the company needs to integrate an external identity provider (IdP) with the company's Anypoint Platform master organization, but SAML 2.0 CANNOT be used. Besides SAML 2.0, what single-sign-on standard can the company use to integrate the IdP with their Anypoint Platform master organization?

SAML 1.0

OAuth 2.0

Basic Authentication

OpenID Connect

6. A company is building an application network and has deployed four Mule APIs: one experience API, one process API, and two system APIs. The logs from all the APIs are aggregated in an external log aggregation tool. The company wants to trace messages that are exchanged between multiple API implementations .

What is the most idiomatic (based on its intended use) identifier that should be used to implement Mule event tracing across the multiple API implementations?

Mule event ID

Mule correlation ID

Client's IP address

DataWeave UUID

7. A Mule application is deployed to a cluster of two(2) cusomter-hosted Mule runtimes.

Currently the node name Alice is the primary node and node named bob is the secondary node. The mule application has a flow that polls a directory on a file system for new files.

The primary node Alice fails for an hour and then restarted.

After the Alice node completely restarts, from what node are the files polled, and what node is now the primary node for the cluster?

Files are polled from Alice node Alice is now the primary node

Files are polled form Bob node Alice is now the primary node

Files are polled from Alice node Bob is the now the primary node

Files are polled form Bob node Bob is now the primary node

8. What aspect of logging is only possible for Mule applications deployed to customer-hosted Mule runtimes, but NOT for Mule applications deployed to CloudHub?

To send Mule application log entries to Splunk

To change tog4j2 tog levels in Anypoint Runtime Manager without having to restart the Mule application

To log certain messages to a custom log category

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

9. An organization uses one specific CloudHub (AWS) region for all CloudHub deployments.

How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?

Workers belonging to a given environment are assigned to the same AZ within that region.

AZs are selected as part of the Mule application's deployment configuration.

Workers are randomly distributed across available AZs within that region.

An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ

10. 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

Page 2 of 4

11. 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

12. 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

13. 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

14. 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

15. 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.

16. Refer to the exhibit.

An organization deploys multiple Mule applications to the same customer -hosted Mule runtime. Many of these Mule applications must expose an HTTPS endpoint on the same port using a server-side certificate that rotates often.

What is the most effective way to package the HTTP Listener and package or store the server-side certificate when deploying these Mule applications, so the disruption caused by certificate rotation is minimized?

Package the HTTPS Listener configuration in a Mule DOMAIN project, referencing it from all Mule applications that need to expose an HTTPS endpoint Package the server-side certificate in ALL Mule APPLICATIONS that need to expose an HTTPS endpoint

Package the HTTPS Listener configuration in a Mule DOMAIN project, referencing it from all Mule applications that need to expose an HTTPS endpoint. Store the server-side certificate in a shared filesystem location in the Mule runtime's classpath, OUTSIDE the Mule DOMAIN or any Mule APPLICATION

Package an HTTPS Listener configuration In all Mule APPLICATIONS that need to expose an HTTPS endpoint Package the server-side certificate in a NEW Mule DOMAIN project

22. 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

28. 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

29. 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 .
