MuleSoft Certified Integration Architect - Level 1 MAINTENANCE - MCIA-Level-1-Maintenance FREE EXAM DUMPS QUESTIONS & ANSWERS]

Question 1

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)

A. Tests for flows cannot be created with Mule errors raised inside
the flow or already existing in the incoming event B. A recorded flow execution ends successfully but the result does
not reach its destination because the application is killed C. The recorder support loops where the structure of the data been tested changes inside the iteration D. Recorder supports smoking a message before or inside a ForEach processor E. Mocking values resulting from parallel processes are possible and will not affect the execution of the processes that follow in the test

Question 2

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?

A. HTTP status 401 unauthorized for policy violation B. HTTP status 400 from the rate-limiting policy violation since the call does not reach the back-end C. HTTP status 429 as defined in the HTTP:RETRY EXHAUSTED error handler in the API B. HTTP status 500 as defined in the ANY error handler in the API since an API:RETRY_EXHAUSTED will be generated

Question 3

A company is planning to extend its Mule APIs to the Europe region. Currently all new applications are deployed to Cloudhub in the US region following this naming convention
{API name}-{environment}. for example, Orders-SAPI-dev, Orders-SAPI-prod etc.
Considering there is no network restriction to block communications between API's, what strategy should be implemented in order to apply the same new API's running in the EU region of CloudHub as well to minimize latency between API's and target users and systems in Europe?

A. Set region property to Europe (eu-de) in API manager for all the mule application Change the naming convention to {API name}-{environment}-{region} and communicate this change to the consuming applications and users B. Set region property to Europe (eu-de) in runtime manager for all the mule application Change the naming convention to {API name}-{environment}-{region} and communicate this change to the consuming applications and users C. Set region property to Europe (eu-de) in runtime manager for all the mule application No need to change the naming convention D. Set region property to Europe (eu-de) in API manager for all the mule application No need to change the naming convention

Question 4

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 API producer should be requested to run the old version in parallel with the new one. B. The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run. C. The API client code ONLY needs to be changed if it needs to take advantage of new features. D. The API producer should be contacted to understand the change to existing functionality.

Question 5

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?

A. Change applications by use an event-driven model B. Add a load balancer and add additional servers in a cluster configuration C. Add a load balancer and add additional servers in a server group configuration D. Increase physical specifications of server CPU memory and network

Question 6

An airline is architecting an API connectivity project to integrate its flight data into an online aggregation website. The interface must allow for secure communication high-performance and asynchronous message exchange.
What are suitable interface technologies for this integration assuming that Mulesoft fully supports these technologies and that Anypoint connectors exist for these interfaces?

A. AsyncAPI over HTTPS
AMQP with RabbitMQ JSON/REST over HTTPS B. CSV over FTP YAM L over TLS JSON over HTTPS C. SOAP over HTTPS HOP over TLS gRPC over HTTPS D. XML over ActiveMQ XML over SFTP XML/REST over HTTPS

Question 7

An organization is evaluating using the CloudHub shared Load Balancer (SLB) vs creating a CloudHub dedicated load balancer (DLB). They are evaluating how this choice affects the various types of certificates used by CloudHub deployed Mule applications, including MuleSoft-provided, customer-provided, or Mule application-provided certificates. What type of restrictions exist on the types of certificates for the service that can be exposed by the CloudHub Shared Load Balancer (SLB) to external web clients over the public internet?

A. Underlying Mule applications need to implement own certificates B. Only self signed certificates can be used C. All certificates which can be used in shared load balancer need to get approved by raising support ticket D. Only MuleSoft provided certificates can be used for server side certificate

Question 8

A manufacturing company is planning to deploy Mule applications to its own Azure Kubernetes Service infrastructure.
The organization wants to make the Mule applications more available and robust by deploying each Mule application to an isolated Mule runtime in a Docker container while managing all the Mule applications from the MuleSoft-hosted control plane.
What is the most idiomatic (used for its intended purpose) choice of runtime plane to meet these organizational requirements?

A. Anypoint Runtime Fabric B. Anypoint Service Mesh C. CloudHub D. Anypoint Platform Private Cloud Edition

Question 9

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?

A. 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 B. 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 C. 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 D. 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

Question 10

Mule application is deployed to Customer Hosted Runtime. Asynchronous logging was implemented to improved throughput of the system. But it was observed over the period of time that few of the important exception log messages which were used to rollback transactions are not working as expected causing huge loss to the Organization. Organization wants to avoid these losses. Application also has constraints due to which they cant compromise on throughput much. What is the possible option in this case?

A. Logging needs to be changed from asynchronous to synchronous B. External log appender needs to be used in this case C. Persistent memory storage should be used in such scenarios D. Mixed configuration of asynchronous or synchronous loggers should be used to log exceptions via synchronous way
