MCD - Level 1 Exam - Question 83

Question

Refer to the exhibits.

The input array of strings is processed by the batch job that processes, filters, and aggregates the values.

What is the last message logged by the Logger component after the batch job completes processing?

Examice · Accepted Answer

The batch job first filters out 'b' from the array ['a', 'b', 'c', 'd', 'e'], leaving ['a', 'c', 'd', 'e']. Then, it transforms the remaining elements to uppercase, resulting in ['A', 'C', 'D', 'E']. The batch aggregator processes the records in groups of three. The first aggregation will be ['A', 'C', 'D'], and the second aggregation will be ['E']. Since the question asks for the last message logged by the Logger component, the correct answer is ['E']. Therefore, the last message logged by the Logger component is 'E'.
