CCA175 - Spark Configuration

Hi, Can someone help what kind of question can be asked to cover this topic? We will be writing code in pyspark or spark-shell so wont be submitting any job so how will this topic be evaluated? OR will they provide a code and ask us to submit using spark-submit with these configuration?

Configuration

This is a practical exam and the candidate should be familiar with all aspects of generating a result, not just writing code.
Supply command-line options to change your application configuration, such as increasing available memory
