During the batch job Load and Dispatch phase, what data structure is created to hold the records for processing?

• A. Map
• B. Set
• C. Queue
• D. Array

Answer: (C)

During a batch job, the Load phase gathers all the records, and the Dispatch phase places those records into a queue so multiple workers can pull items off and process them in parallel. A queue fits this role because it provides a simple, orderly way to distribute work in FIFO order as resources become available. This is ideal for processing many records efficiently across parallel steps. Other structures don’t match this use: a Map is for key-value pairs, a Set enforces unique elements without a processing order, and an Array is just a static list without built-in mechanisms to feed multiple workers.
