Organization wants to achieve high availability goal for Mule applications in customer hosted runtime plane. Due to the complexity involved, data cannot be shared among of different instances of same Mule application. What option best suits to this requirement considering high availability is very much critical to the organization?

• The cluster can be configured
• Use third party product to implement load balancer
• High availability can be achieved only in CloudHub
• Use persistent object store

A company is implementing a new Mule application that supports a set of critical functions driven by a rest API enabled, claims payment rules engine hosted on oracle ERP. As designed the mule application requires many data transformation operations as it performs its batch processing logic. The company wants to leverage and reuse as many of its existing java-based capabilities (classes, objects, data model etc.) as possible What approach should be considered when implementing required data mappings and transformations between Mule application and Oracle ERP in the new Mule application?

• Create a new metadata RAML classes in Mule from the appropriate Java objects and then perform transformations via Dataweave
• From the mule application, transform via theXSLT model
• Transform by calling any suitable Java class from Dataweave
• Invoke any of the appropriate Java methods directly, create metadata RAML classes and then perform required transformations via Dataweave

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

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?

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

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

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

Which Salesforce API is invoked to deploy, retrieve, create or delete customization information such as custom object definitions using a Mule Salesforce connector in a Mule application?

• Metadata API
• REST API
• SOAP API
• Bulk API

An organization has implemented the cluster with two customer hosted Mule runtimes is hosting an application. This application has a flow with a JMS listener configured to consume messages from a queue destination. As an integration architect can you advise which JMS listener configuration must be used to receive messages in all the nodes of the cluster?

• Use the parameter primaryNodeOnly= "false" on the JMS listener
• Use the parameter primaryNodeOnly= "false" on the JMS listener with a shared subscription
• Use the parameter primaryNodeOnly= "true" on the JMS listener with a non-shared subscription
• Use the parameter primaryNodeOnly= "true" on the JMS listener

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.

An organization is designing Mule application which connects to a legacy backend. It has been reported that backend services are not highly available and experience downtime quite often. As an integration architect which of the below approach you would propose to achieve high reliability goals?

• Alerts can be configured in Mule runtime so that backend team can be communicated when services are down
• Until Successful scope can be implemented while calling backend API's
• On Error Continue scope to be used to call in case of error again
• Create a batch job with all requests being sent to backend using that job as per the availability of backend API's
