Question 56

Refer to the exhibit. A Mule application is deployed to a cluster of two customer-hosted Mule runtimes. The Mule application has a flow that polls a database and another flow with an HTTP Listener.
HTTP clients send HTTP requests directly to individual cluster nodes.
What happens to database polling and HTTP request handling in the time after the primary (master) node of the cluster has failed, but before that node is restarted?

A.Database polling continues
Only HTTP requests sent to the remaining node continue to be accepted

B.Database polling stops
All HTTP requests are rejected

C.Database polling stops
All HTTP requests continue to be accepted

D.Database polling continues
All HTTP requests continue to be accepted, but requests to the failed node incur increased latency

Question 57

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 receivesONE 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

Question 58

An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the API's public portal. The API endpoint does NOT change in the new version. How should the developer of an API client respond to this change?

A.The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run.

B.The API producer should be contacted to understand the change to existing functionality.

C.The API producer should be requested to run the old version in parallel with the new one.

D.The API client code ONLY needs to be changed if it needs to take advantage of new features.

Question 59

A new Mule application under development must implement extensive data transformation logic. Some of the data transformation functionality is already available as external transformation services that are mature and widely used across the organization; the rest is highly specific to the new Mule application.
The organization follows a rigorous testing approach, where every service and application must be extensively acceptance tested before it is allowed to go into production.
What is the best way to implement the data transformation logic for this new Mule application while minimizing the overall testing effort?

A.Extend the existing transformation services with new transformation logic and Invoke them from the new Mule application

B.Implement and expose all transformation logic as mlaoservices using DataWeave, so it can be reused by any application component that needs it, including the new Mule application

C.Implement transformation logic in the new Mute application using DataWeave, invoking existing transformation services when possible

D.Implement transformation logic in the new Mute application using DataWeave, replicating the transformation logic of existing transformation services

Question 60

A Mule application uses an HTTP Request operation to invoke an external API.
The external API follows the HTTP specification for proper status code usage.
What is a possible cause when a 3xx status code is returned to the HTTP Request operation from the external API?

A.The request was ACCEPTED by the external API

B.The request was REDIRECTED to a different URL by the external API

C.The request was NOT RECEIVED by the external API

D.The request was NOT ACCEPTED by the external API
