1) doyou have experiance in mule3. 2) what are the diff btw mule3 and mule4. 3) what are the versions runtime you are using 4) what is the diff btv flow, subflow, private 5) FTP/SFTP--and configuration , diff operations  6) filesize is more and have less vcores what you can do. 7) what is a scheduler. 8) what is fixed freequency, cron 9) cloud hub default timezone--Ans:UTC 10)how to sechedu a scheduler after before scheduler complete. 11) re-connection stratogy , where we will apply 12) untill successfull 13) what are the scopes you have worked. 14) the file size is bigger , no workers available. 15)System A and B provide data asynchronously: The data is not available at the same time. You need to aggregate the data: Data from both systems must be combined and sent to a destination. Handle timing differences: Since both systems don't return data simultaneously, you must wait for data from both or handle data persistence. 16) what is the output of parllel for eatch. 17) what is maxc...

**Company 1:** 1) What is batch processing in mule4 ? Ans: Let’s discuss Batch Processing. MuleSoft  allows you to process messages as a batch which can be achieved by batch scope. Batch scope in a mule application can divide the input payload into individual records, performs actions on these individual records, and then sends the processed data to target systems. Batch job divides payload as 100 records a batch, like that it will process 16 threads at a time. Batch has three phases in Mule 4. Load And Dispatch:    It will create job instances, convert payload into collection of records and then split the collection into individual records for processing. Process: In this   phase, it processes all individual records asynchronously. Batch step in this phase allows you to filter records. We can also use batch aggregator processor to aggregate records into groups. For example, if you want to process 10 as one group, you can set the aggregate processor size as 10 ....
