2. 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

3. 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

4. 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.

The organization wants to monitor these APIs by running health checks: for example, to determine if an API can properly accept and process requests. The organization does not have subscriptions to any external monitoring tools and also does not want to extend its IT footprint.

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

5. A Mule application contains a Batch Job scope with several Batch Step scopes. The Batch Job scope is configured with a batch block size of 25.

A payload with 4,000 records is received by the Batch Job scope.

When there are no errors, how does the Batch Job scope process records within and between the Batch Step scopes?

The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records Each Batch Step scope is invoked with one record in the payload of the received Mule event For each Batch Step scope, all 25 records within a block are processed in parallel All the records in a block must be completed before the block of 25 records is available to the next Batch Step scope

The Batch Job scope processes each record block sequentially, one at a time Each Batch Step scope is invoked with one record in the payload of the received Mule event For each Batch Step scope, all 25 records within a block are processed sequentially, one at a time All 4000 records must be completed before the blocks of records are available to the next Batch Step scope

The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records Each Batch Step scope is invoked with one record in the payload of the received Mule event For each Batch Step scope, all 25 records within a block are processed sequentially, one record at a time All the records in a block must be completed before the block of 25 records is available to the next Batch Step scope

The Batch Job scope processes multiple record blocks in parallel Each Batch Step scope is invoked with a batch of 25 records in the payload of the received Mule event For each Batch Step scope, all 4000 records are processed in parallel Individual records can jump ahead to the next Batch Step scope before the rest of the records finish processing in the current Batch Step scope

6. An organization has an HTTPS-enabled Mule application named Orders API that receives requests from another Mule application named Process Orders.

The communication between these two Mule applications must be secured by TLS mutual authentication (two-way TLS).

At a minimum, what must be stored in each truststore and keystore of these two Mule applications to properly support two-way TLS between the two Mule applications while properly protecting each Mule application's keys?

Orders API truststore: The Orders API public key Process Orders keystore: The Process Orders private key and public key

Orders API truststore: The Orders API private key and public key Process Orders keystore: The Process Orders private key public key

Orders API truststore: The Process Orders public key Orders API keystore: The Orders API private key and public key Process Orders truststore: The Orders API public key Process Orders keystore: The Process Orders private key and public key

Orders API truststore: The Process Orders public key Orders API keystore: The Orders API private key Process Orders truststore: The Orders API public key Process Orders keystore: The Process Orders private key

7. A rale limiting policy has been applied to a soap VI.2 API published in Clondhub. The API implementation catches errors in a global error handler on error propagate in the main flow for HTTP: RETRY_EXHAUSTED with HTTP status set to 429 and any with the HTTP status set to 500.

What is the expected H1TP status when the client exceeds the quota of the API calls?

HTTP status 429 as defined in the HTTP: RETRY EXHAUSTED error handler in the API

HTTP status 500 as defined in the ANY error handler in the API since an API: RETRY_EXHAUSTED will be generated

HTTP status 401 unauthorized for policy violation

HTTP status 400 from the rate-limiting policy violation since the call does not reach the back-end

8. A company is designing an integration Mule application to process orders by submitting them to a back-end system for offline processing. Each order will be received by the Mule application through an HTTP5 POST and must be acknowledged immediately.

Once acknowledged the order will be submitted to a back-end system. Orders that cannot be successfully submitted due to the rejections from the back-end system will need to be processed manually (outside the banking system).

The mule application will be deployed to a customer hosted runtime and will be able to use an existing ActiveMQ broker if needed. The ActiveMQ broker is located inside the organization's firewall. The back-end system has a track record of unreliability due to both minor network connectivity issues and longer outages.

Which combination of Mule application components and ActiveMQ queues are required to ensure automatic submission of orders to the back-end system while supporting but minimizing manual order processing?

One or more On Error scopes to assist calling the back-end system An Untill successful scope containing VM components for long retries A persistent dead-letter VM queue configure in Cloud hub

An Until Successful scope to call the back-end system One or more ActiveMQ long-retry queues One or more ActiveMQ dead-letter queues for manual processing

One or more on-Error scopes to assist calling the back-end system one or more ActiveMQ long-retry queues A persistent dead-letter Object store configuration in the CloudHub object store service

A batch job scope to call the back in system An Untill successful scope containing Object Store components for long retries. A dead-letter object store configured in the Mule application

What is the most performant way of implementing this requirement?

Implement a scatter-gather scope to invoke the two vendor applications on two different route Use the Until-Successful scope to implement the retry mechanism for timeout errors on each route

Implement a Choice scope to invoke the two vendor applications on two different route Use the try-catch scope to implement the retry mechanism for timeout errors on each route

Implement a For-Each scope to invoke the two vendor applications Use until successful scope to implement the retry mechanism for the timeout errors

Implement Round-Robin scope to invoke the two vendor applications on two different routes Use the Try-Catch scope to implement retry mechanism for timeout errors on each route

10. 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?

Scaffold the client application with the new definition

Scaffold API implementation application with the new definition

Update the REST connector from exchange in the client application

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

11. An organization is creating a Mule application that will be deployed to CloudHub. The Mule application has a property named dbPassword that stores a database user’s password.

The organization's security standards indicate that the dbPassword property must be hidden from every Anypoint Platform user after the value is set in the Runtime Manager Properties tab.

What configuration in the Mule application helps hide the dbPassword property value in Runtime Manager?

Use secure::dbPassword as the property placeholder name and store the cleartext (unencrypted) value in a secure properties placeholder file

Use secure::dbPassword as the property placeholder name and store the property encrypted value in a secure properties placeholder file

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

12. 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

13. A project uses Jenkins to implement CI/CD process. It was observed that each Mule package contains some of the Jenkins files and folders for configurations of CI/CD jobs.

As these files and folders are not part of the actual package, expectation is that these should not be part of deployed archive.

Which file can be used to exclude these files and folders from the deployed archive?

muleignore

_unTrackMule

mulelnclude

_muleExclude

14. What is not true about Mule Domain Project?

This allows Mule applications to share resources

15. 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.

2 vCores

4 vCores

16 vCores

17. When the mule application using VM is deployed to a customer-hosted cluster or multiple cloudhub workers, how are messages consumed by the Mule engine?

in non-deterministic way

by starting an XA transaction for each new message

in a deterministic way

the primary only in order to avoid duplicate processing

18. 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. The travel company will publish the initial design documents to Anypoint Exchange, then share those documents with the business partners. When using an API-led approach, what is the first design document the travel company should deliver to its business partners?

Create a WSDL specification using any XML editor

Create a RAML API specification using any text editor

Create an OAS API specification in Design Center

Create a SOAP API specification in Design Center

The API consumer creates an API client which sends API invocations to an API such that they are processed by an API implementation

An API client creates an API consumer, which receives API invocation from an API such that they are processed for an API implementation

The API client creates an API consumer which sends API invocations to an API such that they are processed by API implementation

20. What condition requires using a CloudHub Dedicated Load Balancer?

When cross-region load balancing is required between separate deployments of the same Mule application

When custom DNS names are required for API implementations deployed to customer-hosted Mule runtimes

When API invocations across multiple CloudHub workers must be load balanced

21. 1. A leading bank implementing new mule API.

The purpose of API to fetch the customer account balances from the backend application and display them on the online platform the online banking platform. The online banking platform will send an array of accounts to Mule API get the account balances.

As a part of the processing the Mule API needs to insert the data into the database for auditing purposes and this process should not have any performance related implications on the account balance retrieval flow

How should this requirement be implemented to achieve better throughput?

Implement the Async scope fetch the data from the backend application and to insert records in the Audit database

Implement a for each scope to fetch the data from the back-end application and to insert records into the Audit database

Implement a try-catch scope to fetch the data from the back-end application and use the Async scope to insert records into the Audit database

Implement parallel for each scope to fetch the data from the backend application and use Async scope to insert the records into the Audit database

22. 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

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

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

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

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

24. 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?

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

What inputs are required for the application to securely consumed these files?

ATLS context Key Store requiring the private key and certificate for the company PGP public key of partner PGP private key for the company

ATLS context first store containing a public certificate for partner ftps server and the PGP public key of the partner TLS contact Key Store containing the FTP credentials

TLS context trust or containing a public certificate for the ftps server The FTP username and password The PGP public key of the partner

The PGP public key of the partner The PGP private key for the company The FTP username and password

27. An organization is building a test suite for their applications using m-unit. The integration architect has recommended using test recorder in studio to record the processing flows and then configure unit tests based on the capture events

What are the two considerations that must be kept in mind while using test recorder (Choose two answers)

Tests for flows cannot be created with Mule errors raised inside the flow or already existing in the incoming event

Recorder supports smoking a message before or inside a ForEach processor

The recorder support loops where the structure of the data been tested changes inside the iteration

A recorded flow execution ends successfully but the result does not reach its destination because the application is killed

Mocking values resulting from parallel processes are possible and will not affect the execution of the processes that follow in the test

28. An organization is using Mulesoft cloudhub and develops API's in the latest version. As a part of requirements for one of the API's, third party API needs to be called. The security team has made it clear that calling any external API needs to have include listing

As an integration architect please suggest the best way to accomplish the design plan to support these requirements?

Implement includelist IP on the cloudhub VPC firewall to allow the traffic

Implement the validation of includelisted IP operation

Implement the Any point filter processor to implement the include list IP

Implement a proxy for the third party API and enforce the IPinclude list policy and call this proxy from the flow of the API
