You have an embarrassingly parallel or distributed batch job on a large amount of data running using Data Science Jobs

What would be the best approach to run the workload?

A. Create the job in Data Science Jobs and then start the number of simultaneous job runs required for your workload.

B. 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.

C. Reconfigure the job run because Data science jobs does not support embarrassingly parallel.

D. Create a new job for every job run that you have to run in parallel, because the Date Science Jobs service can have only one job run per job.

As you are working in your notebook session, you find that your notebook session does not have enough compute CPU and memory for your workload. How would you scale up your notebook session without losing your work?

A. Ensure your files and environments are written to the block volume storage under the /home/datascience directory, deactivate the notebook session, and activate the notebook larger compute shape selected.

B. Down your files and data to your local machine, delete your notebook session, provision tebook session on a larger compute shape, and upload your files from your local the new notebook session.

C. Deactivate your notebook session, provision a new notebook session on larger compute shape, and re-create all your file changes.

D. Create a temporary bucket in Object Storage, write all your files and data to Object Storage, delete tur ctebook session, provision a new notebook session on a larger com-pute shape, and capy your flies and data from your temporary bucket onto your new notebook session.
