I have scheduled CCA175 exam in couple of days, can you please clarify on below questions on priority . Thanks in advance.
1. Can we use sparkSQL to solve given questions? Is there any restrictions to solve questions using only spark core API or Data frame?
2. I have read that system time will not be available for exam , to keep track of exam can we use wrist watch or table clock? or we have to reply only on proctor for keeping time track?
3.Evaluation of result is based on exact & complete dataset saved in desired directory or if the results is saved but its not in exact desired format then also partial points are given. Partial points are considered or not?
