High

Low

Zero

Use a function

NEW QUESTION 79
Which OCI service provides a scalable environment for developers and data scientists to run Apache Spark applications at scale?

Data Science

NEW QUESTION 80
Which is NOT a valid OCI Data Science notebook session approach?

Ensure you don’t execute long-running Python processes in a notebook cell

Run the process directly in the terminal and use Python logging to get updates on the progress of your job

Avoid having multiple users in the same notebook session due to the possibility of resource contention and write conflicts

While connecting to data in OCI Object Storage from your notebook session, the best practice is to make a local copy on the device and then upload it to your notebook session block volume

Authenticate using your notebook session’s resource principal to access other OCI resources. Resource principals provide a more secure way to authenticate to resources compared to the OCI configuration and API approach

NEW QUESTION 86
You are working in your notebook session and 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?

Deactivate your notebook session, provision a new notebook session on a larger compute shape, and recreate all your file changes

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

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 with a larger compute shape selected

Create a temporary bucket in Object Storage, write all your files and data to Object Storage, delete the notebook session, provision a new notebook session on a larger compute shape, and copy your files and data from your temporary bucket to your new notebook session
