Measure the impact of the centre for enablement

build and publish foundational assets

agree upon KPI's and help develop and overall success plan

evangelize API's

Questions # 2:

A system API EmployeeSAPI is used to fetch employee's data from an underlying SQL database.

The architect must design a caching strategy to query the database only when there is an update to the employees stable or else return a cached response in order to minimize the number of redundant transactions being handled by the database.

What must the architect do to achieve the caching objective?

Options:

Use an On Table Row on employees table and call invalidate cache

Use an object store caching strategy and expiration interval to empty

Use a Scheduler with a fixed frequency every hour triggering an invalidate cache flow

Use an object store caching strategy and expiration interval to empty

Use a Scheduler with a fixed frequency every hour triggering an invalidate cache flow

Use an object store caching strategy and set expiration interval to 1-hour

Use an on table rule on employees table call invalidate cache and said new employees data to cache

Use an object store caching strategy and set expiration interval to 1-hour

Questions # 3:

An organization's security requirements mandate centralized control at all times over authentication and authorization of external applications when invoking web APIs managed on Anypoint Platform.

What Anypoint Platform feature is most idiomatic (used for its intended purpose), straightforward, and maintainable to use to meet this requirement?

Options:

Client management configured in access management

Identity management configured in access management

Enterprise Security module coded in Mule applications

External access configured in API Manager

Questions # 4:

In one of the critical payment related mule application, transaction is being used . As an enhancement to implementation , scatter gather route is introduced which is also the part of transaction group. Scatter gather route has 4 routes.

What will be the behavior of the Mule application in case of error occurs in 4th route of the scatter-gather router and transaction needs to be rolled back?

Options:

Only errored route will be rolled back

All routes will be rolled back

Scatter Gather router cannot be part of transaction

Questions # 5:

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?

Options:

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

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

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

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

Questions # 6:

A Mule application is running on a customer-hosted Mule runtime in an organization's network. The Mule application acts as a producer of asynchronous Mule events. Each Mule event must be broadcast to all interested external consumers outside the Mule application. The Mule events should be published in a way that is guaranteed in normal situations and also minimizes duplicate delivery in less frequent failure scenarios.

The organizational firewall is configured to only allow outbound traffic on ports 80 and 443. Some external event consumers are within the organizational network, while others are located outside the firewall.

What Anypoint Platform service is most idiomatic (used for its intended purpose) for publishing these Mule events to all external consumers while addressing the desired reliability goals?

Options:

CloudHub VM queues

Anypoint MQ

Anypoint Exchange

CloudHub Shared Load Balancer

Questions # 7:

A mule application is required to periodically process large data set from a back-end database to Salesforce CRM using batch job scope configured properly process the higher rate of records.

The application is deployed to two cloudhub workers with no persistence queues enabled.

What is the consequence if the worker crashes during records processing?

Options:

Remaining records will be processed by a new replacement worker

Remaining records be processed by second worker

Remaining records will be left and processed

All the records will be processed from scratch by the second worker leading to duplicate processing

Questions # 8:

A Mule application is built to support a local transaction for a series of operations on a single database. The Mule application has a Scatter-Gather that participates in the local transaction.

What is the behavior of the Scatter-Gather when running within this local transaction?

Options:

Execution of each route within the Scatter-Gather occurs sequentially

Any error that occurs inside the Scatter-Gather will result in a rollback of all the database operations

Execution of all routes within the Scatter-Gather occurs in parallel

Any error that occurs inside the Scatter-Gather will result in a rollback of all the database operations

Execution of each route within the Scatter-Gather occurs sequentially

Any error that occurs inside the Scatter-Gather will NOT result in a rollback of any of the database operations

Execution of each route within the Scatter-Gather occurs in parallel

Any error that occurs inside the Scatter-Gather will NOT result in a rollback of any of the database operations

Questions # 9:

What aspects of a CI/CD pipeline for Mule applications can be automated using MuleSoft-provided Maven plugins?

Options:

Compile, package, unit test, validate unit test coverage, deploy

Compile, package, unit test, deploy, integration test (Incorrect)

Compile, package, unit test, deploy, create associated API instances in API Manager

Import from API designer, compile, package, unit test, deploy, publish to Anypoint Exchange

Answer

Explanation

Correct answer is "Compile, package, unit test, validate unit test coverage, deploy" Explanation : Anypoint Platform supports continuous integration and continuous delivery using industry standard tools Mule Maven Plugin The Mule Maven plugin can automate building, packaging and deployment of Mule applications from source projects Using the Mule Maven plugin, you can automate your Mule application deployment to CloudHub, to Anypoint Runtime Fabric, or on-premises, using any of the following deployment strategies • CloudHub deployment • Runtime Fabric deployment • Runtime Manager REST API deployment • Runtime Manager agent deployment MUnit Maven Plugin The MUnit Maven plugin can automate test execution, and ties in with the Mule Maven plugin. It provides a full suite of integration and unit test capabilities, and is fully integrated with Maven and Surefire for integration with your continuous deployment environment. Since MUnit 2.x, the coverage report goal is integrated with the maven reporting section. Coverage Reports are generated during Maven’s site lifecycle, during the coverage-report goal. One of the features of MUnit Coverage is to fail the build if a certain coverage level is not reached. MUnit is not used for integration testing Also publishing to Anypoint Exchange or to create associated API instances in API Manager is not a part of CICD pipeline which can ne achieved using mulesoft provided maven plugin

Explanation

Architecture mentioned in the question can be diagrammatically put as below. Persistent Object Store is the correct answer .

* Mule Object Stores: An object store is a facility for storing objects in or across Mule applications. Mule uses object stores to persist data for eventual retrieval.

Mule provides two types of object stores:

1) In-memory store – stores objects in local Mule runtime memory. Objects are lost on shutdown of the Mule runtime. So we cant use in memory store in our scenario as we want to share watermark within all cloudhub workers

2) Persistent store – Mule persists data when an object store is explicitly configured to be persistent. Hence this watermark will be available even any of the worker goes down

Questions # 10:

A company is planning to migrate its deployment environment from on-premises cluster to a Runtime Fabric (RTF) cluster. It also has a requirement to enable Mule applications deployed to a Mule runtime instance to store and share data across application replicas and restarts.

How can these requirements be met?

Options:

Anypoint object store V2 to share data between replicas in the RTF cluster

Install the object store pod on one of the cluster nodes

Configure Persistence Gateway in any of the servers using Mule Object Store

Configure Persistent Gateway at the RTF
