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.

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

B.

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 session with a larger compute shape selected

C.

Download all 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

D.

Deactivate your notebook session, provision a new notebook session on a larger compute shapeand re-create all of your file changes

After you have created and opened a notebook session, you want to use the Accelerated Data Science (ADS) SDK to access your data and get started with exploratory data analysis. From which TWO places can you access the ADS SDK?

A.

Oracle Big Data Service

B.

Oracle Machine Learning

C.

Conda environment in OCI Data Science

D.

Python Package Index (PyPI)

E.

Which statement about resource principals is true?

A.

When you authenticate using a resource principal, you need to create and manage credentials to access OCI resources.

B.

A resource principal is not a secure way to authenticate to resources, compared to the OCI configuration and API key approach.

C.

The Data Science service does not provide authentication via a notebook session’s or job run’s resource principal to access other OCI resources.

D.

A resource principal is a feature of IAM that enables resources to be authorized principal actors.

Global behaviour of a machine learning model may be complex, while the local behaviour may be approximated with a simpler surrogate model

B.

Model-agnostic techniques are more interpretable than techniques that are dependent on the types of models

C.

Global and local behaviours of machine learning models are similar

D.

Local explanation techniques are model-agnostic, while global explanation techniques are not
