Question 1

An organization wants MuleSoft-hosted runtime plane features (such as HTTP load balancing, zero downtime, and horizontal and vertical scaling) in its Azure environment. What runtime plane minimizes the organization's effort to achieve these features?

AAnypoint Runtime Fabric

BAnypoint Platform for Pivotal Cloud Foundry

CCloudHub

DA hybrid combination of customer-hosted and MuleSoft-hosted Mule runtimes

Answer : A

Correct Answer: Anypoint Runtime Fabric

*****************************************

>> When a customer is already having an Azure environment, It is not at all an ideal approach to go with hybrid model having some Mule Runtimes hosted on Azure and some on MuleSoft. This is unnecessary and useless.

>> CloudHub is a Mulesoft-hosted Runtime plane and is on AWS. We cannot customize to point CloudHub to customer's Azure environment.

>> Anypoint Platform for Pivotal Cloud Foundry is specifically for infrastructure provided by Pivotal Cloud Foundry

>> Anypoint Runtime Fabric is right answer as it is a container service that automates the deployment and orchestration of Mule applications and API gateways. Runtime Fabric runs within a customer-managed infrastructure on AWS, Azure, virtual machines (VMs), and bare-metal servers.

-Some of the capabilities of Anypoint Runtime Fabric include:

-Isolation between applications by running a separate Mule runtime per application.

-Ability to run multiple versions of Mule runtime on the same set of resources.

-Scaling applications across multiple replicas.

-Automated application fail-over.

-Application management with Anypoint Runtime Manager.

Question 2

A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?

AWhen there are a large number of existing common assets shared by development teams

BWhen various teams responsible for creating APIs are new to integration and hence need extensive training

CWhen development is already organized into several independent initiatives or groups

DWhen the majority of the applications in the application network are cloud based

Answer : C

Correct Answer: When development is already organized into several independent initiatives

*****************************************

>> It would require lot of process effort in an organization to have a single C4E team coordinating with multiple already organized development teams which are into several independent initiatives. A single C4E works well with different teams having at least a common initiative. So, in this scenario, federated C4E works well instead of centralized C4E.

Question 3

What Anypoint Connectors support transactions?

ADatabase, JMS, VM

BDatabase, 3MS, HTTP

CDatabase, JMS, VM, SFTP

DDatabase, VM, File

Answer : A

Question 4

What Mule application can have API policies applied by

Anypoint Platform to the endpoint exposed by that Mule application?

A) A Mule application that accepts requests over HTTP/1.x

B) A Mule application that accepts JSON requests over TCP but is NOT required to provide a response

C) A Mute application that accepts JSON requests over WebSocket

D) A Mule application that accepts gRPC requests over HTTP/2

AOption A

BOption B

COption C

DOption D

Answer : A

Correct Answer: Option A

*****************************************

>> Anypoint API Manager and API policies are applicable to all types of HTTP/1.x APIs.

>> They are not applicable to WebSocket APIs, HTTP/2 APIs and gRPC APIs

Question 5

An API implementation is updated. When must the RAML definition of the API also be updated?

AWhen the API implementation changes the structure of the request or response messages

BWhen the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system

CWhen the API implementation is migrated from an older to a newer version of the Mule runtime

DWhen the API implementation is optimized to improve its average response time

Answer : A

Correct Answer: When the API implementation changes the structure of the request

*****************************************

>> RAML definition usually needs to be touched only when there are changes in the request/response schemas or in any traits on API.

>> It need not be modified for any internal changes in API implementation like performance tuning, backend system migrations etc..

Question 6

What is most likely NOT a characteristic of an integration test for a REST API implementation?

AThe test needs all source and/or target systems configured and accessible

BThe test runs immediately after the Mule application has been compiled and packaged

CThe test is triggered by an external HTTP request

DThe test prepares a known request payload and validates the response payload

Answer : B

Correct Answer: The test runs immediately after the Mule application has been

*****************************************

>> Integration tests are the last layer of tests we need to add to be fully covered.

>> These tests actually run against Mule running with your full configuration in place and are tested from external source as they work in PROD.

>> These tests exercise the application as a whole with actual transports enabled. So, external systems are affected when these tests run.

So, these tests do NOT run immediately after the Mule application has been compiled and packaged.

FYI... Unit Tests are the one that run immediately after the Mule application has been compiled and packaged.

Question 7

Refer to the exhibit.

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?

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

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

CWorkers are randomly distributed across available AZs within that region

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

Answer : D

Correct Answer:Workers are randomly distributed across available AZs within that region.

*****************************************

>>Currently, we only have control to choose which AWS Region to choose but there is no control at all using any configurations or deployment options to decide what Availability Zone (AZ) to assign to what worker.

>>There areNOfixed or implicit rules on platform too w.r.t assignment of AZ to workers based on environment or application.

>>They are completely assigned inrandom. However, cloudhub definitely ensures that HA is achieved by assigning the workers to more than on AZ so that all workers are not assigned to same AZ for same application.
