1. 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?

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

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

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

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.

2. 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?

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

Upgrade vCore size from 0.1 vCore to 0,2 vCore

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

Add an additional Cloudhub worker to provide additional capacity

3. In Anypoint Platform, a company wants to configure multiple identity providers (IdPs) for multiple lines of business (LOBs). Multiple business groups, teams, and environments have

been defined for these LOBs.

What Anypoint Platform feature can use multiple IdPs across the company’s business groups, teams, and environments?

MuleSoft-hosted (CloudHub) dedicated load balancers

Client (application) management

Virtual private clouds

Permissions

4. An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.

A developer is building Munit test suit for a newly developed mule application that sends API request to an external rest API.

What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

Invoke the external endpoint of the rest API from the mule floors

Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API

Mock the rest API invocation in the Munits and return a mock response for those invocations

Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

5. 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

Shut out bad actors by using HTTPS mutual authentication for all API invocations

Apply a JSON threat protection policy to all APIs to detect potential threat vectors

6. An organization is successfully using API led connectivity, however, as the application network grows, all the manually performed tasks to publish share and discover, register, apply policies to, and deploy an API are becoming repetitive pictures driving the organization to automate this process using efficient CI/'CD pipeline. Considering Anypoint platforms capabilities how should the organization approach automating is API lifecycle?

Use runtime manager rest apis for API management and mavenforAPI deployment

Use Maven with a custom configuration required for the API lifecycle

Use Anypoint CLI or Anypoint Platform REST apis with scripting language such as groovy

Use Exchange rest api's for API management and MavenforAPI deployment

7. An insurance provider is implementing Anypoint platform to manage its application infrastructure and is using the customer hosted runtime for its business due to certain financial requirements it must meet. It has built a number of synchronous API's and is currently hosting these on a mule runtime on one server

These applications make use of a number of components including heavy use of object stores and VM queues.

Business has grown rapidly in the last year and the insurance provider is starting to receive reports of reliability issues from its applications.

The DevOps team indicates that the API's are currently handling too many requests and this is over loading the server. The team has also mentioned that there is a significant downtime when the server is down for maintenance.

As an integration architect, which option would you suggest to mitigate these issues?

Add a load balancer and add additional servers in a server group configuration

Add a load balancer and add additional servers in a cluster configuration

Increase physical specifications of server CPU memory and network

Change applications by use an event-driven model

8. A travel company wants to publish a well-defined booking service API to be shared with its business partners. These business partners have agreed to ONLY consume SOAP services and they want to get the service contracts in an easily consumable way before they start any development.

What is the most idiomatic (used for its intended purpose) Anypoint connector, validator, or scope that can be configured in the Mule application to filter duplicate sales orders on the basis of the unique ID field contained in each sales order record?

Configure a Cache scope to filter and store each record from the received file by the order ID

Configure a Database connector to filter and store each record by the order ID

Configure an Idempotent Message Validator component to filter each record by the order ID

Configure a watermark In an On New or Updated File event source to filter unique records by the order ID

10. 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 scope that participates in the local transaction.

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

Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations

Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back

Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations

Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back

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

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

28. An organization has implemented a continuous integration (CI) lifecycle that promotes Mule applications through code, build, and test stages. To standardize the organization's CI journey, a new dependency control approach is being designed to store artifacts that include information such as dependencies, versioning, and build promotions.

To implement these process improvements, the organization will now require developers to maintain all dependencies related to Mule application code in a shared location.

What is the most idiomatic (used for its intended purpose) type of system the organization should use in a shared location to standardize all dependencies related to Mule application code?

A MuleSoft-managed repository at repository.mulesoft.org

A binary artifact repository

API Community Manager

The Anypoint Object Store service at cloudhub.io

29. An organization has deployed both Mule and non-Mule API implementations to integrate its customer and order management systems. All the APIs are available to REST clients on the public internet.

What Anypoint Platform feature provides the most idiomatic (used for its intended purpose) way to monitor the availability of both the Mule and the non-Mule API implementations?

API Functional Monitoring

Runtime Manager

API Manager

Anypoint Visualizer

30. 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?

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

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

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

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