QUESTION: 137

An organization has just developed a Mule application that implements a REST API. The mule application will be deployed to a cluster of customer hosted Mule runtimes.
What additional infrastructure component must the customer provide in order to distribute inbound API requests across the Mule runtimes of the cluster?

A message broker
An HTTP Load Balancer
A database
An Object Store

Answer(s): B

Explanation:

Correct answer is An HTTP Load Balancer.
Key thing to note here is that we are deploying application to customer hosted Mule runtime. This means we will need load balancer to route the requests to different instances of the cluster. Rest all options are distractors and their requirement depends on project use case.

Implement a scatter-gather scope to invoke the two vendor applications on two different route
Use the Until-Successful scope to implement the retry mechanism for timeout errors on each route
Implement a Choice scope to invoke the two vendor applications on two different route Use the try-catch scope to implement the retry mechanism for timeout errors on each route
Implement a For-Each scope to invoke the two vendor applications Use until successful scope to implement the retry mechanism for the timeout errors
Implement Round-Robin scope to invoke the two vendor applications on two different routes Use the Try-Catch scope to implement retry mechanism for timeout errors on each route

QUESTION: 140

An application deployed to a runtime fabric environment with two cluster replicas is designed to periodically trigger of flow for processing a high-volume set of records from the source system and synchronize with the SaaS system using the Batch job scope

After processing 1000 records in a periodic synchronization of 1 lakh records, the replicas in which batch job instance was started went down due to unexpected failure in the runtime fabric environment
What is the consequence of losing the replicas that run the Batch job instance?

The remaining 99000 records will be lost and left and processed
The second replicas will take over processing the remaining
99000 records
A new replacement replica will be available and will be process all 1,00,000 records from scratch leading to duplicate record processing
A new placement replica will be available and will take or processing the remaining 99,000 records
