B. They spend 80% of their time on failed analytics projects and 20% doing useful work.
C. They spend 80% of their time analyzing data and 20% finding and preparing it.

Question 2

Which statement about resource principals is true?

A. A resource principal is a feature of IAM that enables resources to be authorized principal actors.
B. The Data Science service does not provide authentication via a notebook session’s or job run’s resource principal to access other OCI resources.
C. A resource principal is not a secure way to authenticate to resources, compared to the OCI configuration and API key approach.
D. When you authenticate using a resource principal, you need to create and manage credentials to access OCI resources.

Question 3

You are a data scientist trying to load data into your notebook session. You understand that Accelerated Data Science (ADS) SDK supports loading various data formats. Which of the following THREE are ADS-supported data formats?

A. Raw Images
B. DOCX
C. Pandas DataFrame
D. XML
E. JSON

Question 4

You’re going to create an Oracle Cloud Infrastructure Anomaly Detection model for multivariate dat a. Where do you need to store the training data?

A. MySQL database
B. Object Storage Bucket
C. Autonomous Data Warehouse
D. Your local machine

Question 5

You have received machine learning model training code, without clear information about the optimal shape to run the training. How would you proceed to identify the optimal compute shape for your model training that provides a balanced cost and processing time?

A. Start with the strongest compute shape Jobs support and monitor the Job Run metrics and time required to complete the model training. Tune the model so that it utilizes as much compute resources as possible, even at an increased cost
B. Start with a random compute shape and monitor the utilization metrics and time required to finish the model training. Perform model training optimizations and performance tests in advance to identify the right compute shape before running the model training as a job
C. Start with a smaller shape and monitor the Job Run metrics and time required to complete the model training. If the compute shape is not fully utilized, tune the model parameters, and rerun the job. Repeat the process until the shape resources are fully utilized
D. Start with a smaller shape and monitor the utilization metrics and time required to complete the model training. If the compute shape is fully utilized, change to compute that has more resources and rerun the job. Repeat the process until the processing time does not improve
