A Mule application contains a Batch Job with two Batch Steps (Batch_Step_l and Batch_Step_2). A payload with 1000 records is received by the Batch Job.

How many threads are used by the Batch Job to process records, and how does each Batch Step process records within the Batch Job?

A. Each Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and RECORDS are processed IN PARALLEL within and between the two Batch Steps

B. Each Batch Job uses a SINGLE THREAD for all Batch steps Each Batch step instance receives ONE record at a time as the payload, and RECORDS are processed IN ORDER, first through Batch_Step_l and then through Batch_Step_2

C. Each Batch Job uses a SINGLE THREAD to process a configured block size of record Each Batch Step instance receives A BLOCK OF records as the payload, and BLOCKS of records are processed IN ORDER

D. Each Batch Job uses SEVERAL THREADS for the Batch Steps Each Batch Step instance receives ONE record at a time as the payload, and BATCH STEP INSTANCES execute IN PARALLEL to process records and Batch Steps in ANY order as fast as possible

A retailer is designing a data exchange interface to be used by its suppliers. The interface must support secure communication over the public internet. The interface must also work with a wide variety of programming languages and IT

systems used by suppliers.

What are suitable interface technologies for this data exchange that are secure, cross- platform, and internet friendly, assuming that Anypoint Connectors exist for these interface technologies?

A. EDJFACT XML over SFTP JSON/REST over HTTPS

B. SOAP over HTTPS HOP over TLS gRPC over HTTPS

C. XML over ActiveMQ XML over SFTP XML/REST over HTTPS

D. CSV over FTP YAML over TLS JSON over HTTPS

An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.

A developer is building Munit test suit for a newly developed mule application that sends API request to an external rest API.

What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

A. Invoke the external endpoint of the rest API from the mule floors

B. Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API

C. Mock the rest API invocation in the Munits and return a mock response for those invocations

D. Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

Refer to the exhibit.

A Mule application is being designed to expose a SOAP web service to its clients.

What language is typically used inside the web service's interface definition to define the data structures that the web service Is expected to exchange with its clients?

A. WSDL

B. XSD

C. JSON Schema

D. RAMI

What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST API's, Anypoint CLI or the Mule Maven plugin?

A. By default, the Anypoint CLI and Mule Maven plugin are not included in the Mule runtime

B. Access to Anypoint Platform API;s and Anypoint CLI can be controlled separately thruough the roles and permissions in Anypoint platform, so that specific users can get access to Anypoint CLI while others get access to the platform API's

C. Anypoint Platform API's can only automate interactions with CloudHub while the Mule maven plugin is required for deployment to customer hosted Mule runtimes

D. API policies can be applied to the Anypoint platform API's so that only certain LOS's has access to specific functions

One of the backend systems involved by the API implementation enforces rate limits on the number of request a particle client can make.

Both the back-end system and API implementation are deployed to several non-production environments including the staging environment and to a particular production environment. Rate limiting of the back-end system applies to all non-production environments.

The production environment however does not have any rate limiting.

What is the cost-effective approach to conduct performance test of the API implementation in the non-production staging environment?

A. Including logic within the API implementation that bypasses in locations of the back-end system in the staging environment and invoke a Mocking service that replicates typical back-end system responses Then conduct performance test using this API implementation

B. Use MUnit to simulate standard responses from the back-end system. Then conduct performance test to identify other bottlenecks in the system

C. Create a Mocking service that replicates the back-end system's production performance characteristics Then configure the API implementation to use the mocking service and conduct the performance test

D. Conduct scaled-down performance tests in the staging environment against rate-limiting back-end system. Then upscale performance results to full production scale

A key Cl/CD capability of any enterprise solution is a testing framework to write and run repeatable tests.

Which component of Anypoint Platform provides the te6t automation capabilities for customers to use in their pipelines?

A. Anypoint CLl

B. Mule Maven Plugin

C. Exchange Mocking Service

D. MUnit

In one of the critical payment related mule application, transaction is being used . As an enhancement to implementation , scatter gather route is introduced which is also the part of transaction group. Scatter gather route has 4 routes.

What will be the behavior of the Mule application in case of error occurs in 4th route of the scatter-gather router and transaction needs to be rolled back?

A. Only errored route will be rolled back

B. All routes will be rolled back

C. Scatter Gather router cannot be part of transaction

A project team uses RAML specifications to document API functional requirements and deliver API definitions. As per the current legal requirement, all designed API definitions to be augmented with an additional non-functional requirement to protect the services from a high rate of requests according to define service level agreements.

Assuming that the project is following Mulesoft API governance and policies, how should the project team convey the necessary non-functional requirement to stakeholders?

A. Create proxies in API manager for the non functional requirement and publish to exchange

B. Add all non functional requirements as comments to RAML specification and publish to exchange

C. Create various SLA's in API manager for the non functional requirement and publish to exchange

D. Update API definitions with the fragment for the appropriate policy and publish to exchange

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 deplpoyed Mule applications, including MuleSoft-provided, customer-provided, or Mule application-provided certificates.

What type of restrictions exist on the types of certificates that can be exposed by the CloudHub Shared Load Balancer (SLB) to external web clients over the public internet?

A. Only MuleSoft-provided certificates are exposed.

B. Only customer-provided wildcard certificates are exposed.

C. Only customer-provided self-signed certificates are exposed.

D. Only underlying Mule application certificates are exposed (pass-through)
