NEW QUESTION # 53
A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process.
Which implementation should be used to get response data from the external API after it completes processing?
Answer: C
Explanation:
To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly. Reference: https://docs.mulesoft.com/mule-runtime/4.3/http-listener-ref#callback
NEW QUESTION # 54
Which statement is true when using XML SDK for creating custom message processors?
Answer: B
Explanation:
Option C is directly supported by the MuleSoft XML SDK documentation. MuleSoft defines an XML SDK property as a field supplied by an end user of the component that operates at the module configuration level.
Unlike an operation parameter, which applies to one operation invocation, properties configure the XML SDK component across the Mule project in which that configuration is used.
The other choices conflict with documented XML SDK behavior. XML SDK operations do not support recursive calls, so A is false. XML SDK provides outbound operations but does not provide inbound message sources such as schedulers, making B false.
Option D also requires correction. Current XML SDK versions support a visibility setting with values including PUBLIC and PRIVATE; the default is public, but operations are not universally required to remain public. MuleSoft's current XML SDK reference explicitly documents private operation visibility.
Therefore, C is the technically correct and directly documented statement. This is one question where the option selected in the supplied source should not be accepted without verification.
Reference topics: XML SDK Properties; Operations; module configuration; operation visibility; XML SDK limitations.

NEW QUESTION # 55
Refer to the exhibits.
Bioinfo System API is implemented and published to Anypoint Exchange. A developer wants to invoke this API using its REST Connector.
What should be added to the POM?
Answer: A
Explanation:
To invoke Bioinfo System API using its REST Connector, option E should be added to the pom.xml file. This option adds a dependency for Bioinfo System API REST Connector with its group ID, artifact ID, version, classifier, and type. The classifier specifies that it is a REST Connector (raml-client), and the type specifies that it is a Mule plugin (mule-plugin). Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-generate-from-rest-api-task#add-the-api-dependency-to-the-pom-file
NEW QUESTION # 56
Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?
Answer: B
Explanation:
To invoke multiple HTTP APIs in parallel and roll back failed requests in sequence, the developer should use a Scatter-Gather router as a central Saga orchestrator for all API requests with compensating actions for failing routes. A Scatter-Gather router executes multiple routes concurrently and aggregates the results. A Saga orchestrator coordinates a series of actions across different services and handles failures by executing compensating actions. Therefore, using a Scatter-Gather router as a Saga orchestrator allows invoking multiple HTTP APIs in parallel and rolling back any failed requests in sequence. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-concept https://docs.mulesoft.com/mule-runtime/4.3/saga
NEW QUESTION # 57
When registering a client application with an existing API instance or API Group instance, what is required to manually approve or reject request access?
Answer: D
Explanation:
To manually approve or reject request access when registering a client application with an existing API instance or API Group instance, it is required to configure the SLA tier for the application and have one of the following roles or permissions: Organization Administrator, API Manager Environment Administrator, or Manage Contracts permission. These roles or permissions allow managing client applications and contracts in API Manager.
