Realexamdumps Providing most updated MuleSoft Certified Architect Question Answers. Here are a few sample questions:

MuleSoft MCIA-Level-1 Sample Question 1

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?


Options:

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

Answer: D Explanation: Explanation: ExplanationCorrect approach is to use Mixed configuration of asynchronous or synchronous loggers shoud be used to log exceptions via synchronous way Asynchronous logging poses a performance-reliability trade-off. You may lose some messages if Mule crashes before the logging buffers flush to the disk. In this case, consider that you can have a mixed configuration of asynchronous or synchronous loggers in your app. Best practice is to use asynchronous logging over synchronous with a minimum logging level of WARN for a production application. In some cases, enable INFO logging level when you need to confirm events such as successful policy installation or to perform troubleshooting. Configure your logging strategy by editing your application’s src/main/resources/log4j2.xml filf

MuleSoft MCIA-Level-1 Sample Question 2

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?


Options:

A. Create a WSDL specification using any XML editor
B. Create a RAML API specification using any text editor
C. Create an OAS API specification in Design Center
D. Create a SOAP API specification in Design Center

Answer: B

MuleSoft MCIA-Level-1 Sample Question 3

A mule application is being designed to perform product orchestration. The Mule application needs to join together the responses from an inventory API and a Product Sales History API with the least latency.

To minimize the overall latency. What is the most idiomatic (used for its intended purpose) design to call each API request in the Mule application?


Options:

A. Call each API request in a separate lookup call from Dataweave reduce operator
B. Call each API request in a separate route of a Scatter-Gather
C. Call each API request in a separate route of a Parallel For Each scope
D. Call each API request in a separate Async scope

Answer: C

MuleSoft MCIA-Level-1 Sample Question 4

An organization has defined a common object model in Java to mediate the communication between different Mule applications in a consistent way. A Mule application is being built to use this common object model to process responses from a SOAP API and a REST API and then write the processed results to an order management system.

The developers want Anypoint Studio to utilize these common objects to assist in creating mappings for various transformation steps in the Mule application.

What is the most idiomatic (used for its intended purpose) and performant way to utilize these common objects to map between the inbound and outbound systems in the Mule application?


Options:

A. Use JAXB (XML) and Jackson (JSON) data bindings
B. Use the WSS module
C. Use the Java module
D. Use the Transform Message component

Answer: A Explanation: Reference: [Reference: https://docs.mulesoft.com/mule-runtime/3.9/understanding-mule-configuration , , , ]

MuleSoft MCIA-Level-1 Sample Question 5

A Mule application is deployed to a cluster of two(2) cusomter-hosted Mule runtimes. Currently the node name Alice is the primary node and node named bob is the secondary node. The mule application has a flow that polls a directory on a file system for new files.

The primary node Alice fails for an hour and then restarted.

After the Alice node completely restarts, from what node are the files polled, and what node is now the primary node for the cluster?


Options:

A. Files are polled from Alice nodeAlice is now the primary node
B. Files are polled form Bob nodeAlice is now the primary node
C. Files are polled from Alice nodeBob is the now the primary node
D. Files are polled form Bob nodeBob is now the primary node

Answer: D Explanation: Explanation: Explanation* Mule High Availability Clustering provides basic failover capability for Mule. * When the primary Mule Runtime becomes unavailable, for example, because of a fatal JVM or hardware failure or it’s taken offline for maintenance, a backup Mule Runtime immediately becomes the primary node and resumes processing where the failed instance left off. * After a system administrator recovers a failed Mule Runtime server and puts it back online, that server automatically becomes the backup node. In this case, Alice, once up, will become backup ---------------------------------------------------------------------------------------------------------------------------------------------- Reference: https://docs.mulesoft.com/mule-runtime/4.3/hadr-guide So correct choice is : Files are polled form Bob node Bob is now the primary nodf

MuleSoft MCIA-Level-1 Sample Question 6

An organization is designing a Mule application to periodically poll an SFTP location for new files containing sales order records and then process those sales orders. Each sales order must be processed exactly once.

To support this requirement, the Mule application must identify and filter duplicate sales orders on the basis of a unique ID contained in each sales order record and then only send the new sales orders to the downstream system.

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?


Options:

A. Configure a Cache scope to filter and store each record from the received file by the order ID
B. Configure a Database connector to filter and store each record by the order ID
C. Configure an Idempotent Message Validator component to filter each record by the order ID
D. Configure a watermark In an On New or Updated File event source to filter unique records by the order ID

Answer: C Explanation: Reference: [Reference: https://docs.mulesoft.com/mule-runtime/3.9/idempotent-filter , , , , ]

MuleSoft MCIA-Level-1 Sample Question 7

An organization 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 HTTPS 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 rejections from the back-end system will need to be processed manually (outside the back-end system).

The Mule application will be deployed to a customer-hosted runtime and is 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.

What idiomatic (used for their intended purposes) 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?


Options:

A. 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
B. One or more On Error scopes to assist calling the back-end system An Until Successful scope containing VM components for long retries A persistent dead-letter VM queue configured in CloudHub
C. 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 configured in the CloudHub Object Store service
D. A Batch Job scope to call the back-end system An Until Successful scope containing Object Store components for long retries A dead-letter object store configured in the Mule application

Answer: B
