An organization designing a hybrid, load balanced, single cluster production environment. Due to performance service level agreement goals, it is looking into running the Mule applications in an active-active multi node cluster configuration.

What should be considered when running its Mule applications in this type of environment?

A.

All event sources, regardless of time , can be configured as the target source by the primary node in the cluster

B.

An external load balancer is required to distribute incoming requests throughout the cluster nodes

C.

A Mule application deployed to multiple nodes runs in an isolation from the other nodes in the cluster

D.

Although the cluster environment is fully installed configured and running, it will not process any requests until an outage condition is detected by the primary node in the cluster.

As a part of design , Mule application is required call the Google Maps API to perform a distance computation. The application is deployed to cloudhub.

At the minimum what should be configured in the TLS context of the HTTP request configuration to meet these requirements?

A.

The configuration is built-in and nothing extra is required for the TLS context

B.

Request a private key from Google and create a PKCS12 file with it and add it in keyStore as a part of TLS context

C.

Download the Google public certificate from a browser, generate JKS file from it and add it in key store as a part of TLS context

D.

Download the Google public certificate from a browser, generate a JKS file from it and add it in Truststore as part of the TLS context

How does timeout attribute help inform design decisions while using JMS connector listening for incoming messages in an extended architecture (XA) transaction?

A.

After the timeout is exceeded, stale JMS consumer threads are destroyed and new threads are created

B.

The timeout specifies the time allowed to pass between receiving JMS messages on the same JMS connection and then after the timeout new JMS connection is established

C.

The time allowed to pass between committing the transaction and the completion of the mule flow and then after the timeout flow processing triggers an error

D.

The timeout defines the time that is allowed to pass without the transaction ending explicitly and after the timeout expires, the transaction rolls back

A trading company handles millions of requests a day. Due to nature of its business, it requires excellent

performance and reliability within its application.

For this purpose, company uses a number of event-based API's hosted on various mule clusters that communicate across a shared message queue sitting within its network.

Which method should be used to meet the company's requirement for its system?

A.

XA transactions and XA connected components

B.

JMS transactions

C.

JMS manual acknowledgements with a reliability pattern

D.

VM queues with reliability pattern

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?

A.

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

B.

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

C.

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

D.

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

Customer has deployed mule applications to different customer hosted mule run times. Mule applications are managed from Anypoint platform.

What needs to be configured to monitor these Mule applications from Anypoint monitoring and what sends monitoring data to Anypoint monitoring?

A.

Enable monitoring of individual applications from runtime manager application settings

Runtime manager agent sends monitoring data from the mule applications to Anypoint monitoring

B.

Install runtime manager agent on each mule runtime

Runtime manager agent since monitoring data from the mule applications to Anypoint monitoring

C.

Anypoint monitoring agent on each mule runtime

Anypoint monitoring agent sends monitoring data from the mule applications to Anypoint monitoring

D.

By default, Anypoint monitoring agent will be installed on each Mule run time

Anypoint Monitoring agent automatically sends monitoring data from the Mule applications to Anypoint monitoring

A project team is working on an API implementation using the RAML definition as a starting point. The team has updated the definition to include new operations and has published a new version to exchange. Meanwhile another team is working on a mule application consuming the same API implementation.

During the development what has to be performed by the mule application team to take advantage of the newly added operations?

A.

Scaffold the client application with the new definition

B.

Scaffold API implementation application with the new definition

C.

Update the REST connector from exchange in the client application

D.

Update the API connector in the API implementation and publish to exchange

What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?

A.

A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design

B.

The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region

C.

The FQDNs are determined by the application name, but can be modified by an administrator after deployment

D.

The FQDNs are determined by both the application name and the region

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?

A.

Use the parameter primaryNodeOnly= "false" on the JMS listener

B.

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

C.

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

D.

Use the parameter primaryNodeOnly= "true" on the JMS listener

A banking company is developing a new set of APIs for its online business. One of the critical API's is a master lookup API which is a system API. This master lookup API uses persistent object store. This API will be used by all other APIs to provide master lookup data.

Master lookup API is deployed on two cloudhub workers of 0.1 vCore each because there is a lot of master data to be cached. Master lookup data is stored as a key value pair. The cache gets refreshed if they key is not found in the cache.

Doing performance testing it was observed that the Master lookup API has a higher response time due to database queries execution to fetch the master lookup data.

Due to this performance issue, go-live of the online business is on hold which could cause potential financial loss to Bank.

As an integration architect, which of the below option you would suggest to resolve performance issue?

A.

Implement HTTP caching policy for all GET endpoints for the master lookup API and implement locking to synchronize access to object store

B.

Upgrade vCore size from 0.1 vCore to 0,2 vCore

C.

Implement HTTP caching policy for all GET endpoints for master lookup API

D.

Add an additional Cloudhub worker to provide additional capacity
