MCIA-LEVEL-1 Online Practice Questions and Answers

An integration Mule application is deployed to a customer-hosted multi-node Mule 4 runtime duster. The Mule application uses a Listener operation of a JMS connector to receive incoming messages from a JMS queue.

How are the messages consumed by the Mule application?

A. Depending on the JMS provider's configuration, either all messages are consumed by ONLY the primary cluster node or else ALL messages are consumed by ALL cluster nodes

B. Regardless of the Listener operation configuration, all messages are consumed by ALL cluster nodes

C. Depending on the Listener operation configuration, either all messages are consumed by ONLY the primary cluster node or else EACH message is consumed by ANY ONE cluster node

D. Regardless of the Listener operation configuration, all messages are consumed by ONLY the primary cluster node

An organization has just developed a Mule application that implements a REST API. The mule application will be deployed to a cluster of customer hosted Mule runtimes.

What additional infrastructure component must the customer provide in order to distribute inbound API requests across the Mule runtimes of the cluster?

A. A message broker

B. An HTTP Load Balancer

C. A database

D. An Object Store

An auto mobile company want to share inventory updates with dealers Dl and D2 asynchronously and concurrently via queues Q1 and Q2. Dealer Dl must consume the message from the queue Q1 and dealer D2 to must consume a message from the queue Q2.

Dealer D1 has implemented a retry mechanism to reprocess the transaction in case of any errors while processing the inventers updates. Dealer D2 has not implemented any retry mechanism.

How should the dealers acknowledge the message to avoid message loss and minimize impact on the current implementation?

A. Dealer D1 must use auto acknowledgement and dealer D2 can use manual acknowledgement and acknowledge the message after successful processing

B. Dealer D1 can use auto acknowledgement and dealer D2 can use IMMEDIATE acknowledgement and acknowledge the message of successful processing

C. Dealer D1 and dealer D2 must use AUTO acknowledgement and acknowledge the message after successful processing

D. Dealer D1 can use AUTO acknowledgement and dealer D2 must use manual acknowledgement and acknowledge the message after successful processing

What condition requires using a CloudHub Dedicated Load Balancer?

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

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

C. When API invocations across multiple CloudHub workers must be load balanced

D. When server-side load-balanced TLS mutual authentication is required between API implementations and API clients

A customer wants to use the mapped diagnostic context (MDC) and logging variables to enrich its logging and improve tracking by providing more context in the logs.

The customer also wants to improve the throughput and lower the latency of message processing.

As an Mulesoft integration architect can you advise, what should the customer implement to meet these requirements?

A. Use synchronous logging and use pattern layout with [%MDC] in the log4j2.xml configuration file and then configure the logging variables

B. Useasync logger at the level greater than INFO and use pattern layout with [%MDC] in the log4j2,xml configuration file and then configure the logging variables

C. Useasync logger at the level equal to DEBUG orTRACEand use pattern layout with [%MDC] in the log4j2.xml configuration file and then configure the logging variables

D. Use synchronous logging at the INFO DEBUG or Trace level and use pattern layout with [%MDC] in the log4j2.xml configuration file and then configure the logging variables

According to MuleSoft, what is a major distinguishing characteristic of an application network in relation to the integration of systems, data, and devices?

A. It uses a well-organized monolithic approach with standards

B. It is built for change and self-service

C. It leverages well-accepted internet standards like HTTP and JSON

D. It uses CI/CD automation for real-time project delivery

A company is designing a mule application to consume batch data from a partner's ftps server The data files have been compressed and then digitally signed using PGP.

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

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

B. 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

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

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

In which order are the API Client, API Implementation, and API interface components called in a typical REST request?

A. API Client > API implementation > API Interface

B. API interface > API Client > API Implementation

C. API Client > API Interface > API implementation

D. API Implementation > API Interface > API Client

What is true about the network connections when a Mule application uses a JMS connector to interact with a JMS provider (message broker)?

A. To complete sending a JMS message, the JMS connector must establish a network connection with the JMS message recipient

B. To receive messages into the Mule application, the JMS provider initiates a network connection to the JMS connector and pushes messages along this connection

C. The JMS connector supports both sending and receiving of JMS messages over the protocol determined by the JMS provider

D. The AMQP protocol can be used by the JMS connector to portably establish connections to various types of JMS providers

Which integration technology, when used for its typical and intended purpose, meets the retailer's requirements for this use case?

A. Managed File Transfer (MFT)

B. Publish/Subscriber Messaging Bus (Pub/Sub)

C. Enterprise Data Warehouse (EDW)
