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.A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
• B.The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
• C.The FQDNs are determined by the application name, but can be modified by an administrator after deployment
• D.The FQDNs are determined by both the application name and the region

An organization uses one specific CloudHub (AWS) region for all CloudHub deployments. How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?

• A.Workers belonging to a given environment are assigned to the same AZ within that region.
• B.AZs are selected as part of the Mule application's deployment configuration.
• C.Workers are randomly distributed across available AZs within that region.
• D.An AZ is randomly selected for a Mule application, and all the Mule application's CloudHub workers are assigned to that one AZ

An insurance company is implementing a MuleSoft API to get inventory details from the two vendors. Due to network issues, the invocations to vendor applications are getting timed-out intermittently. But the transactions are successful upon reprocessing What is the most performant way of implementing this requirement?

• A.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
• B.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
• C.Implement a For-Each scope to invoke the two vendor applications
  Use until successful scope to implement the retry mechanism for the timeout errors
• D.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

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

Correct Answer: A

* Each Batch Job uses SEVERAL THREADS for the Batch Steps
* Each Batch Step instance receives ONE record at a time as the payload. It's not received in a block, as it does not wait for multiple records to be completed before moving to next batch step. (So Option D is out of choice)
* RECORDS are processed IN PARALLEL within and between the two Batch Steps.
* RECORDS are not processed in order. Let's say if second record completes batch_step_1 before record 1, then it moves to batch_step_2 before record 1. (So option C and D are out of choice)
* A batch job is the scope element in an application in which Mule processes a message payload as a batch of records. The term batch job is inclusive of all three phases of processing: Load and Dispatch, Process, and On Complete.
* A batch job instance is an occurrence in a Mule application whenever a Mule flow executes a batch job. Mule creates the batch job instance in the Load and Dispatch phase. Every batch job instance is identified internally using a unique String known as batch job instance id.

• A.Configure alerts failure conditions in API manager
• B.Enable monitoring of individual applications from Anypoint monitoring
• C.Use any point functional monitoring test API's functional behavior
• D.Configure alerts with failure conditions in runtime manager
