質問 3：
You have an embarrassingly parallel or distributed batch job on a large amount of data that you consider running using Data Science Jobs. What would be the best approach to run the workload?
A. Create the job in Data Science Jobs and start a job run. When it is done, start a new job run until you achieve the number of runs required.
B. Reconfigure the job run because Data Science Jobs does not support embarrassingly parallel workloads.
C. Create the job in Data Science Jobs and then start the number of simultaneous jobs runs required for your workload.
